TIE Line Service A TIE line is a privately leased communication line between two or more PBXs, which provides cost effective communications between company members at different locations. (→ 1.30.1 TIE Line Service) Virtual Private Network (VPN) VPN is a service provided by the telephone company. It uses an existing public line as if it were a private line. (→ 1.30.3 Virtual Private Network (VPN)) QSIG Network QSIG is a protocol based on ISDN (Q.931) and offers enhanced PBX features in a private network of two or more connected PBXs. (→ 1.30.4 QSIG Standard Features) Voice over Internet Protocol (VoIP) Network The PBX can connect to another PBX via a private IP network. In this case, voice signals are converted into IP packets and sent through this network. Automatic rerouting of VoIP calls to public trunks is also available, in case of network difficulties. (→ 1.30.2 Voice over Internet Protocol (VoIP) Network) Built-in Small Call Centre Features An incoming call distribution group (→ 1.2.2 Incoming Call Distribution Group Features) can be used as a small call centre with the following features: Queuing Feature When a preprogrammed number of extensions in an incoming call distribution group are busy, additional incoming calls can wait in a queue. While calls are waiting in the queue, the calls are handled by the Queuing Time Table, which can be assigned for each time mode (day/lunch/break/night). (→ 1.2.2.4 Queuing Feature) Log-in/Log-out Incoming call distribution group members can join (Log-in) or leave (Log-out) the groups manually. While logged-in, a member extension can have a preprogrammed time period automatically for refusing calls after completing the last call (Wrap-up). (→ 1.2.2.7 Log-in/Log-out) VIP Call It is possible to assign a priority to incoming call distribution groups. If an extension belongs to multiple groups and the extension becomes idle, queuing calls in the groups will be distributed to the extension in priority order. (→ 1.2.2.5 VIP Call) Computer Telephony Integration (CTI) Features Connecting a PC to a DPT, or connecting a CTI Server to this PBX, allows functions of the PC, PBX and extension to be integrated so that, for example, detailed caller information can be taken from a database and displayed on the PC as a call arrives, or the PC can dial numbers for the extension automatically. (→ 1.32.1 Computer Telephony Integration (CTI)) PC Phone/PC Console Features This PBX supports PC Phone and PC Console. These Panasonic CTI applications provide advanced features combining telephone and PC, such as the ability to display detailed caller information, including a photograph, on the screen of the PC when a call is received, or to dial a telephone number automatically just by selecting a name (1.32.2 PC Phone/PC Console).

This PBX supports Voice Processing Systems (VPS) with DTMF Integration as well as DPT (Digital) Integration, attached locally and over a network. (→ 1.24 Voice Mail Features) Parallelled Telephone Features By connecting telephones in parallel, you can increase the number of telephones connected to the PBX without adding additional extension cards. (→ 1.11.9 Parallelled Telephone) Parallel Mode An SLT can be connected to an APT or DPT that is connected to a Super Hybrid port of the PBX. The SLT shares the same extension number with the APT or DPT. EXtra Device Port (XDP) Mode An SLT can be connected to a DPT that is connected to a Super Hybrid port of the PBX. Unlike parallel mode, XDP mode allows each telephone to act as an independent extension with its own extension number. Digital XDP A DPT can be connected to another DPT that is connected to a DPT port or a Super Hybrid port of the PBX. Similar to XDP mode, each DPT acts as an independent extension with its own extension number. Portable Station (PS) Features PSs (e.g., KX-TCA255, KX-TD7690) can be connected to this PBX. It is possible to use the PBX features using the PS like a PT. A PS can also be used in parallel with a wired telephone (Wireless XDP Parallel Mode). In this case, the wired telephone is the main telephone and the PS is the sub telephone. (→ 1.25 Portable Station (PS) Features) Hospitality Features This PBX has several features that support its use in a hotel-type environment. Extensions corresponding to guest rooms can be "checked in" or "checked out" by a designated hotel operator, who can also check or set wake-up calls, and print out records of guest charges. (→ 1.27.1 Hospitality Features—SUMMARY) Built-in Simplified Voice Message (SVM) Features By just installing an optional voice message card in the PBX, simple answering machine services can be provided. (→ 1.17.8 Built-in Simplified Voice Message (SVM)) Cellular Phone Features (KX-TDA6920/KX-TDA0920/KX-TDA3920 required) This PBX supports the use of cellular phones and other outside destinations with the PBX. Cellular phones can be treated as extensions within the PBX, and paired with wired telephones in Cellular Phone XDP Parallel Mode. (→ 1.33.1 Cellular Phone Features—SUMMARY)

The call is routed to the operator (Intercept Routing—No Destination). A trunk call is received.

Feature Guide 23 [Programming Example of DID/DDI Table] DDI can be programmed as DID. Note Tenant number and VPS trunk group number can also be assigned in the DID/DDI table. Tenant number is used to determine the time mode (day/lunch/break/night) for the corresponding DID/DDI number. VPS trunk group number is used in Voice Mail DPT (Digital) Integration (→ 1.24.3 Voice Mail DPT (Digital) Integration). Explanation: If the DID/DDI number is "123-4567": 1. Checks the number in the table. → Matches the number in location 0001. 2. Checks the time mode. In Day mode: CLI is enabled. Route to CLI destination. In Lunch mode: CLI is disabled. Route to DID/DDI destination, extension 100. Conditions • To use this feature, DID/DDI service must be assigned as the distribution method for a trunk port. • DID/DDI Number Modification It is possible to modify a received DID/DDI number, which may be convenient when programming the DID/DDI table. The modification method (removed number of digits/added number) can be programmed on a trunk port basis. [Modification Example] Location No.*1 Name*2 CLI*3 Destination*4 Day Lunch ... Day Lunch ... 0001 123-4567 John White Enable Disable ... 105 100 ... 0002 123-2468 Tom Smith Enable Disable ... 102 100 ... 0003 123-456 A company Enable Disable ... 101 101 ... : : : : : : : : : *1: → 2.16.3 [10-3] DDI / DID Table—DDI / DID Number → [451] DID Number *2: → 2.16.3 [10-3] DDI / DID Table—DDI / DID Name → [452] DID Name *3: → 2.16.3 [10-3] DDI / DID Table—CLI Ring for DDI/DID—Day, Lunch, Break, Night *4: → 2.16.3 [10-3] DDI / DID Table—DDI / DID Destination—Day, Lunch, Break, Night → [453] DID Destination Removed number of digits: 6 Added number: 10 Received DID/DDI number: 87654321 Modified DID/DDI number: 876543 21 = 1021 1) Remove the first 6 digits. 2) Add "10".

24 Feature Guide • Inter-digit Time When the Inter-digit time expires, the PBX stops receiving the DID/DDI number and starts to check the DID/DDI table. (Refer to the [Programming Example of DID/DDI Table] above). Even if the Inter-digit time does not expire, the PBX stops receiving the DID/DDI number when the received number is found in the DID/DDI table. The PBX then routes the call to the corresponding destination. If the received number matches several entries in the table, the call is directed to the destination of the first matching entry. [Example] If a call is received in Lunch mode; Programming Manual References PC Programming Manual 2.7.30 [1-1] Slot—DID Card Property 2.8.4 [2-3] Timers & Counters—Miscellaneous—Receiving Dial Inter-digit Timer—DDI / DID 2.16.2 [10-2] DIL Table & Port Settings—DDI / DID / TIE / MSN → Distribution Method → DDI/DID/TIE/MSN—Remove Digit → DDI/DID/TIE/MSN—Additional Dial 2.16.3 [10-3] DDI / DID Table PT Programming Manual [421] BRI DIL/DDI/MSN Selection [451] DID Number [452] DID Name [453] DID Destination Feature Guide References 1.1.1.5 Calling Line Identification (CLI) Distribution 2.2.3 Tenant Service 2.2.4 Time Service 3.1 Capacity of System Resources Received Number Destination Explanation 123-4567 Extn. 100 The PBX finds the match in location 0001 in the table after receiving "7". So the call is routed to extension 100. 123-456 Extn. 101 The Inter-digit time expired after receiving "6". The PBX finds the match in location 0003 in the table. So the call is routed to extension 101.

Feature Guide 25 1.1.1.4 Multiple Subscriber Number (MSN) Ringing Service Description Provides automatic direction of an incoming ISDN-BRI (Basic Rate Interface) line call with an MSN to a preprogrammed destination. One ISDN-BRI port can support a maximum of 10 MSNs. Each MSN has a destination for each time mode (day/lunch/break/night). Point-to-multipoint must be selected for the ISDN configuration. [Method Flowchart] CLI works. Yes Yes No Does the call have its CLI* information and is CLI mode enabled for the time mode? No Is the CLI destination assigned? The call is routed to the MSN destination. The call is routed to the CLI destination. No Yes Yes Is the MSN found in the MSN table? The call is ignored. Is the MSN destination for the time mode assigned? No *: Calling Line Identification (CLI) Distribution: If the CLI routing is enabled and the caller's identification number is assigned in the Caller ID Table, the call will not be routed to the MSN destination, but routed to the CLI destination. No Are any MSNs assigned in the MSN table? Yes The call is routed to the operator (Intercept Routing—No Destination). The call is routed to the operator (Intercept Routing—No Destination). A trunk call is received.

26 Feature Guide [Programming Example of MSN Table for ISDN BRI Port 1] A table can be programmed for each ISDN-BRI port. Each BRI port has 10 MSN locations. → 2.16.6 [10-4] MSN Table Note Tenant number and VPS trunk group number can also be assigned in the MSN table. Tenant number is used to determine the time mode (day/lunch/break/night) for the corresponding MSN. VPS trunk group number is used in Voice Mail DPT (Digital) Integration. → 1.24.3 Voice Mail DPT (Digital) Integration Explanation: If the MSN "123-4567" is received from BRI port 1: 1. Checks the number in the table. → Matches the number in location 01. 2. Checks the time mode. In Day mode: CLI is enabled. Route to CLI destination. In Lunch mode: CLI is disabled. Route to MSN destination, extension 100. Conditions • To use this feature, the MSN service must be assigned as the distribution method for a trunk port. • MSN Modification It is possible to modify a received MSN to make it shorter, which may be convenient when programming the MSN table. The modification method (removed number of digits/added number) can be programmed on a trunk port basis. [Modification Example] • When using point-to-multipoint configuration with a BRI, do not connect another ISDN terminal device in parallel with the PBX. As only two channels can be used at one time with the BRI, the other ISDN terminal device may monopolise both channels. Location No. Name CLI Destination Day Lunch ...

Intercept Routing—Busy If a called party is already handling a call, new calls are handled as follows: – The call is redirected to the preprogrammed Intercept Routing—Busy destination. – If an Intercept Routing—Busy destination is not enabled, the caller will hear a busy tone. However, if the call is made through an LCOT/ELCOT or T1 [LCOT/GCOT] card, the caller hears a ringback tone. Intercept Routing—DND If a called party is in DND mode, the call is redirected to the preprogrammed destination. When the original destination is: The Available Intercept Destination is: • Wired Extension (PT/SLT/T1-OPX) • PS The destination assigned to the original extension. 2.10.1 [4-1-1] Wired Extension—Extension Settings— Intercept Destination → Intercept Destination—When called party does not answer—Day, Lunch, Break, Night → Intercept Destination—When Called Party is Busy 2.10.10 [4-2-1] Portable Station—Extension Settings—Intercept Destination → Intercept Destination—When called party does not answer—Day, Lunch, Break, Night → Intercept Destination—When Called Party is Busy → [604] Extension Intercept Destination

Programming Example

Feature Guide 33 Conditions [General] • Intercept Routing—DND on/off Intercept Routing—DND can be enabled or disabled system programming. If disabled, one of the following is activated depending on the type of line that a call arrives through: a) ELCOT, LCOT, or T1 (LCOT/GCOT) Card: The incoming trunk call will ring at the original destination while the caller hears a ringback tone. b) Other Trunk Cards: A busy tone will be sent to the caller. • If the intercept destination cannot receive the call: a) Intercept Routing—No Answer: Intercept timer will restart at the original destination, until the call is answered. b) Intercept Routing—Busy/DND: The call will be sent back to the original destination when the call arrives through the ELCOT, LCOT or T1 (LCOT/GCOT) card. When the call arrives through other trunk cards the caller will hear a busy tone. • Idle Extension Hunting If an extension is a member of an idle extension hunting group, calls to that extension will not be redirected by Intercept Routing—Busy/DND. If the extension is busy or in DND mode, calls to that extension will be redirected to the next extension in the idle extension hunting group. • Intercept Routing for intercom calls can be enabled or disabled on a system basis. → 2.16.7 [10-5] Miscellaneous—Intercept—Intercept Routing for Extension Call • IRNA Timer The IRNA timer can be set on a system basis and an extension basis for each time mode (day, lunch, break, night). → 2.10.1 [4-1-1] Wired Extension—Extension Settings—Intercept Destination—Intercept No Answer Time—Day, Lunch, Break, Night • The Intercept Routing destination for each time mode will not apply for Intercept Routing—Busy. When the original destination is busy, the call is redirected to the Intercept Routing—Busy destination assigned through system programming. If no destination is assigned the caller will hear a busy tone. • When a call arrives at an extension that is currently receiving a call, the call will be redirected to the extension's Intercept Routing—No Answer destination for each time mode. • The time modes that are selected for trunk calls arriving at extensions and VM groups are decided on a tenant basis.

Each incoming call distribution group has a floating extension number (default: 6 + two-digit group number). Incoming calls directed to an incoming call distribution group are distributed to the member extensions in the group using a distribution method. When a preprogrammed number of extensions in the group are busy, the incoming calls can wait in a queue. Each incoming call distribution group and member extensions can be programmed as desired to handle incoming calls. Calls to the group can be monitored by an extension assigned as a supervisor. 2.9.10 [3-5-1] Incoming Call Distribution Group—Group Settings → Main → Overflow Queuing Busy → Overflow No Answer → Miscellaneous *1: → [622] Incoming Call Distribution Group Floating Extension Number *2: → [623] Incoming Call Distribution Group Name *3: → [624] Incoming Call Distribution Group Distribution Method *4: → [632] Maximum Number of Agents *5: → [628] Queuing Call Capacity *6: → [629] Queuing Hurry-up Level *7: → [626] Overflow Time *8: → [625] Destination for Overflow Time Expiration/[627] Destination When All Busy *9: The tenant number is required to determine the time mode (day/lunch/break/night) (→ 2.2.4 Time Service) and the music source (for Music on Hold) for each group.

Overflow Feature [→ 1.2.2.6 Overflow Feature] A call is redirected to a preprogrammed destination when it cannot be answered or queued (Intercept Routing—Overflow in an Incoming Call Distribution Group). It is also possible to send a busy tone (Busy on Busy) or disconnect the line. 5. Incoming Call Distribution Group Controlling Feature Conditions • One extension can belong to multiple incoming call distribution groups. • ICD Group button An Incoming Call Distribution (ICD) Group button can be assigned on a flexible button for each incoming call distribution group. It receives the incoming calls to the group. One extension can have more than one ICD Group button of the same or different incoming call distribution groups (Multiple ICD Group). If all ICD Group buttons in the same incoming call distribution group are occupied, the next incoming call will be held in a queue or will overflow. If the ICD Group button is not assigned, incoming calls will arrive at the INTERCOM, CO or PDN button. The mode of ICD Group buttons can be selected through system programming, as follows: – Standard Mode (Group DN Button Mode) An extension can have an ICD Group button for an incoming call distribution group that the extension does not belong to through system programming. However, the ICD Group button will not receive calls to that group. – Enhanced Phantom Button Mode An extension can join an ICD Group just by creating a button for that group, even if the extension was not previously registered as a member. When the button is created, the extension will be Feature Description & Reference Log-in/Log-out Member extensions can join the group to handle calls (Log-in) or leave the group for a break (Log- out). They can leave the group temporarily when they are away from their desks, to prevent calls being sent to their extensions. → 1.2.2.7 Log-in/Log-out Supervisory Feature Incoming Call Queue Monitor The supervisor extension can monitor various information about the incoming calls for each incoming call distribution group on his display. → 1.2.2.8 Supervisory Feature Log-in/Log-out Monitor and Remote Control Monitor: The supervisor extension can monitor the log-in/log-out status of the group members.

50 Feature Guide automatically registered in the lowest-numbered available member slot for the group. Calls to the group can be received at the extension with no further programming. If no member slots are available for that group, the button cannot be created and an alarm tone will be heard. When creating an ICD Group button in this mode, the user can also specify the delayed ringing settings. If an extension user deletes the last ICD Group button at his extension for a certain group, he will also be deregistered as a member from that group. • Group FWD The FWD feature can be assigned on an incoming call distribution group basis. • COS for Incoming Call Distribution Groups Each incoming call distribution group is assigned a COS number. Group FWD to an outside party can be enabled or disabled for each COS. The COS for incoming call distribution groups is also used for the Internal Call Block feature; when an extension user calls an incoming call distribution group, the PBX checks the COS of the calling extension against the COS of the incoming call distribution group (→ 1.1.2.2 Internal Call Block).

Feature Guide 51 1.2.2.2 Group Call Distribution Description Incoming calls directed to an incoming call distribution group are distributed to the member extensions using the selected distribution method until a preprogrammed number of extensions (agents) are busy with calls. When incoming calls exceed the number of available extensions, calls enter a queue (→ 1.2.2.4 Queuing Feature). 1. Distribution Method One of the three distribution methods below can be assigned to each incoming call distribution group. Distribution Method Description Uniform Call Distribution (UCD) Calls are distributed evenly to a different extension each time a call is received. Extensions are hunted in a circular way in the preprogrammed order for the group, starting at the extension after the extension that received the last call. Depending on system programming, calls can be directed to the longest idle extension. This is known as Automatic Call Distribution (ACD). Priority Hunting An idle extension is searched for using the preprogrammed order for the group. Ring All extensions in the group ring simultaneously. Delayed Ringing: Delayed ringing or no ringing can be programmed for each extension in the group. The call can be answered by pressing the flashing button even if no ring or a delayed time is set. Extn. A Starts searching from extn. B. (Skips extn. A.) Received the last call. Extn. B Extn. C Extn. D Extn. A 1st Priority 2nd Priority 3rd ....

52 Feature Guide 2. Call Waiting for Incoming Call Distribution Group (Group Call Waiting) When there are no available extensions in an incoming call distribution group, the group members can receive the Call Waiting tone. To use this feature: • Select the Group Call Waiting mode through system programming. This determines the distribution method for waiting calls. • Member extensions must assign the Call Waiting mode individually, or they will not be notified. (→ 1.1.3.3 Call Waiting) [How the Group Call Waiting Feature Activates] [Example] [ICD Group Button for Group Call Waiting] The way that the Group Call Waiting feature works depends on the Group Call Waiting Distribution method as follows: a) Ring: The Group Call Waiting feature activates for all busy member extensions (even when the extensions do not have ICD Group buttons) simultaneously for only one incoming call— additional calls will wait in a queue. b) UCD/Priority Hunting: The Group Call Waiting feature activates on an idle ICD Group button located on busy member extensions in a certain order. (This order depends on the type: UCD or Priority Hunting.) Calls will arrive at idle buttons until all ICD Group buttons are occupied— additional calls will wait in a queue. Note In method b), if an extension has one or more ICD Group buttons for an incoming call distribution group and all the ICD Group buttons on the extension are occupied, the Group Call Waiting feature for the group will not work at the extension. *: Incoming calls enter the queue immediately. Member extensions do not receive the Call Waiting tone.

Feature Guide 53 3. No Reply Redirection (UCD or Priority Hunting Method) If a call received at a member extension is not answered within a preprogrammed time period (No Answer time), the call will be redirected to the next member extension. If there is no idle group member, the call queues at the target extension until a group member becomes available. Conditions • Automatic Call Distribution (ACD) – When a KX-TDA6920, KX-TDA0920 or KX-TDA3920 SD Memory Card for Software Upgrade to Enhanced Version is installed in the PBX, and the distribution type is set to Uniform Call Distribution, it is possible to select whether incoming calls are distributed to idle extensions evenly in order (UCD), or to the extension that has been idle the longest (ACD). – ACD does not work for ISDN extensions or PS Ring Groups. • FWD/DND Extension System programming for each incoming call distribution group is required to skip or ring extensions which have the FWD or DND feature set. If set to ring, the FWD/DND settings are ignored. (→ 1.3.1 Call Forwarding (FWD)/Do Not Disturb (DND)) • The Group Call Waiting feature cannot be used with the VIP Call feature (→ 1.2.2.5 VIP Call) and/or Wrap-up feature (→ 1.2.2.7 Log-in/Log-out). To use the VIP Call feature and/or Wrap-up feature, Call Waiting mode on each extension should be off.

Feature Guide 55 1.2.2.3 Outside Destinations in Incoming Call Distribution Group Description Up to 4 outside parties or destinations at another PBX can be assigned as members of an Incoming Call Distribution (ICD) Group, using the following method: A virtual PS is registered as a member of the ICD Group. Then, the telephone number of the outside destination is specified as the FWD—All Calls destination. Calls to the ICD Group will also ring at the outside destination as if that destination were an extension within the PBX. This is useful in situations such as the following: • An extension user can have his PT and multiple cellular phones ring together for calls. • An employee who is not in the office, but is still available to answer calls, can receive calls to an ICD Group. Cellular Phone XDP Parallel The extension registered first in an ICD Group can programme the Forward settings for trunk calls to up to 4 virtual PSs through PT programming. Using this feature, an extension user can assign his cellular phone to ring with his PT, so that he can easily receive trunk calls even when not at his desk. Conditions • Hardware Requirement The KX-TDA6920, KX-TDA0920 or KX-TDA3920 SD Memory Card for Software Upgrade to Enhanced Version PBX-1 Telephone Company Virtual PS 3 Virtual PS 2 Virtual PS 1 ICD Group Virtual PS 4 PBX-2 TIE Cellular Company

56 Feature Guide • For this feature to be activated, the following conditions must be met: – A virtual PS is assigned as a member of the ICD Group. (→ 1.25.6 Virtual PS) – The forwarding type of the virtual PS is set to All Calls. (→ 1.3.1.2 Call Forwarding (FWD)) – The forwarding destination is an outside party, including an extension at another PBX in the network. – FWD to trunk is allowed through COS programming for the virtual PSs. – The distribution method for the ICD Group is set to Ring. (→ 1.2.2.2 Group Call Distribution) • Up to 4 virtual PSs can be assigned to a single ICD Group. If more than 4 are assigned, the 4 virtual PSs with the lowest member numbers are available. • ELCOT/LCOT trunks without reverse circuit detection (→ 1.5.4.5 Reverse Circuit) and channels of a T1 trunk set to LCOT type do not support this feature. • Calls to an ICD Group will ring at a virtual PS even if all of the other extensions assigned to the group are busy. • If all members of an ICD Group are virtual PSs, and trunk lines are available but the called parties are all busy, neither the queuing or overflow features will operate. Therefore, it is recommended that at least one PT or SLT is also assigned to an ICD Group. • To log in to or out of a group, a virtual PS user can access the PBX through DISA, enter the Walking COS feature number (if required), and access log-in/log-out settings. • Delayed ringing can be assigned for virtual PSs in the same way as for other extensions. • The wrap-up time feature is not available for virtual PSs. • When forwarding calls to a public trunk, system programming selects whether the CLIP number of the calling party or of the virtual PS is sent to the forward destination. When calling using a private network, the CLIP number of the calling party will always be sent.

Feature Guide 57 1.2.2.4 Queuing Feature Description When a preprogrammed number of extensions in an incoming call distribution group are busy, additional incoming calls can wait in a queue. The number of calls which can wait in the queue is programmable. While calls are waiting in the queue, the calls are handled by the Queuing Time Table, which can be assigned for each time mode (day/lunch/break/night) (→ 2.2.4 Time Service). This PBX supports a specified number of Queuing Time Tables which each have a specified number of sequences (specific commands which are performed when a caller enters a queue). The following commands can be assigned to each sequence when making a Queuing Time Table: [Command Table] [Programming Example of Queuing Time Table] Command Description Condition OGM xx An outgoing message is sent to the caller. "xx" applies to the OGM number. After the OGM, Music on Hold will be sent and the next event in the sequence will be activated. b × 5 s Puts the caller in the waiting queue for b (01-16) × 5 seconds. If an OGM has not been sent to the caller, the caller hears a ringback tone. If an OGM has been sent to the caller, the caller hears Music on Hold. Sequence c Redirects to sequence c. "c" applies to the sequence number. None Overflow Redirects to the overflow destination. None Disconnect Disconnects the line. None None (No command) Redirects to the next sequence. If assigned as sequence 01, the Queuing Time Table will not be activated. Queuing Time Table No. Sequence*1 Sequence 01 Sequence 02 Sequence 03 Sequence 04 ... 01 OGM 01 6 × 5 s OGM 03 Overflow 02*2 OGM 02 6 × 5 s OGM 04 None 03 : : : : : : *1: → 2.9.11 [3-5-2] Incoming Call Distribution Group—Queuing Time Table—Queuing Sequence— Sequence 01–16 → [631] Sequences in Queuing Time Table *2: If a call has not reached a destination by the time the final sequence is completed, the call will be disconnected.

58 Feature Guide Explanation for Queuing Time Table 01: Conditions • If the call is transferred to the incoming call distribution group and is handled by the Queuing Time Table: Transfer Recall will not occur even if the Transfer Recall time expires. • Manual Queue Redirection It is possible to redirect the longest waiting call in a queue to the overflow destination by pressing the Hurry-up button. (If the call is already ringing at an extension, it will not be redirected.)

60 Feature Guide 1.2.2.5 VIP Call Description It is possible to assign a priority to incoming call distribution groups. If an extension belongs to multiple groups and the extension becomes idle, queuing calls in the groups will be distributed to the extension in priority order. Each incoming call distribution group can enable or disable the VIP Call mode. When multiple groups enable the VIP Call mode, the incoming call distribution group with the lowest numbered group has the highest priority. When multiple groups disable the VIP Call mode, queuing calls are distributed to extensions uniformly. [Example] In the call centre, incoming call distribution groups 1 and 3 enable the VIP Call mode, while incoming call distribution groups 2 and 4 disable the VIP Call mode.

Feature Guide 61 1.2.2.6 Overflow Feature Description When waiting calls exceed the waiting queue capacity, they may be redirected to a preprogrammed destination or a busy tone may be sent to the callers by the following features: 1) Intercept Routing—Overflow in an Incoming Call Distribution Group 2) Busy on Busy 1. Intercept Routing—Overflow in an Incoming Call Distribution Group Intercept Routing—Overflow in an Incoming Call Distribution Group works in one of following conditions: a) There is no space in the waiting queue. b) The Queuing Time Table is not assigned and there are no extensions logged in. c) An Overflow command is assigned to the Queuing Time Table. d) The Overflow time expires. e) Manual Queue Redirection is performed. [Available Destination] The overflow destinations can be assigned for each incoming call distribution group and each time mode (day/lunch/break/night) (→2.2.4 Time Service). The destination can be assigned as follows, depending on the above conditions. • For a) and b): → 2.9.10 [3-5-1] Incoming Call Distribution Group—Group Settings—Overflow Queuing Busy—Queuing Busy—Destination-Day, Lunch, Break, Night → [627] Destination When All Busy • For c), d), and e): → 2.9.10 [3-5-1] Incoming Call Distribution Group—Group Settings—Overflow No Answer— Time out & Manual Queue Redirection—Destination-Day, Lunch, Break, Night → [625] Destination for Overflow Time Expiration Destination Availability Wired Extension (PT/SLT/ISDN Extension/T1-OPX) PS Incoming Call Distribution Group PS Ring Group Floating Extension no. for SVM VM Group (DTMF/DPT) External Pager (TAFAS) DISA Analogue/ISDN Remote Maintenance Idle Line Access no. + Phone no.

62 Feature Guide 2. Busy on Busy The Busy on Busy feature works when the destination for the Intercept Routing—Overflow in an Incoming Call Distribution Group feature is not assigned in one of the following conditions: a) There is no space in the Waiting queue. b) The Queuing Time Table is not assigned and there are no extensions logged-in. [Example of a)] There are five assistants in a shop. When the answering agent number is "2", and the queuing call number is "0": If two of the assistants are talking on the phone, the next caller will hear a busy tone to prevent the caller from thinking that there is no one in the shop or that the shop is closed. Conditions [Intercept Routing—Overflow in an Incoming Call Distribution Group] • If the Overflow time expires, and the overflow destination is unavailable: a) If the trunk call arrives through the ELCOT, LCOT or T1 (LCOT/GCOT) card: (1) If the call was once in a queue and an outgoing message (OGM) was sent to it, or the call reached an incoming call distribution group by using the DISA feature (→ 1.17.6 Direct Inward System Access (DISA)): The line is disconnected. (2) In all other cases: Redirection is ignored and the Overflow timer activates again. b) If the call arrives through another card: Redirection is ignored and the Overflow timer activates again. [Busy on Busy] • If a trunk call arrives through the ELCOT, LCOT or T1 (LCOT/GCOT) card, a busy tone will not be sent to the caller.

64 Feature Guide 1.2.2.7 Log-in/Log-out Description Members of an incoming call distribution group can join (Log-in) or leave (Log-out) the group manually. They can leave the group temporarily when they are away from their desks, to prevent calls being sent to their extensions. They can return to the group when they are ready to answer calls. Wrap-up: While logged in, a member extension can have a preprogrammed time period automatically for refusing calls after completing the previous call (Wrap-up time). While the Wrap-up timer is active, calls to all incoming call distribution groups to which the extension belongs will skip the extension so that the extension user can perform necessary tasks such as reporting on the previous call. Wrap-up mode can also be activated manually (Not Ready) by pressing the Wrap-up button. [Log-in/Log-out and Wrap-up Status Example] Conditions • It is programmable whether the last remaining logged-in extension can log out. • Log-in/Log-out Button A flexible button can be customised as the Log-in/Log-out button with the following parameters: Parameter Usage Light Pattern Red on Off No parameter Used with an ICD Group button, or with the floating extension number of an incoming call distribution group, or with (All). — — Floating extension number of a specified incoming call distribution group Used to log in to or out of the specified incoming call distribution group.

Feature Guide 65 • If an ICD Group button is assigned, it also shows the log-in/log-out status of the corresponding group. The light pattern is the same as the Log-in/Log-out button that includes the group number. • Wrap-up Timer – Two wrap-up timers can be programmed, an ICD Group member wrap-up timer and an extension wrap-up timer. System programming selects which timer is used. When the ICD Group member wrap-up timer is selected, the timer is only activated after calls to the extension through an ICD Group. When the extension wrap-up timer is selected, the timer is activated after all calls to or from the extension, including a retrieved call on hold. – Only calls from ICD Groups cannot be received during the wrap-up time. Other calls are received as normal. – The wrap-up timer does not work for ISDN extensions or PS Ring Groups. • Wrap-up Button A flexible button can be customised as the Wrap-up button. It shows the current status as follows: • When a PS in Wireless XDP Parallel Mode completes a call, neither the PS nor its wired telephone can have Wrap-up time. (→ 1.25.5 Wireless XDP Parallel Mode) • Automatic Log-out A member extension may be logged out automatically, if the Unanswered time expires a preprogrammed number of times consecutively. The number of consecutive unanswered calls can be assigned for each incoming call distribution group. If the extension is a member of more than one incoming call distribution group, the unanswered number is counted across all corresponding incoming call distribution groups. It is possible to return to log-in mode manually. The Automatic Log-out feature does not work for extensions in an incoming call distribution group using the Ring distribution method (→ 1.2.2.2 Group Call Distribution). • Log-in/Log-out Monitor The supervisor extension can monitor and control the log-in/log-out status of the incoming call distribution group members. (→ 1.2.2.8 Supervisory Feature) • Log-in/Log-out Information on SMDR Log-in/Log-out information can be printed out on SMDR.

Feature Guide 69 1.3 Call Forwarding (FWD)/Do Not Disturb (DND) Features 1.3.1 Call Forwarding (FWD)/Do Not Disturb (DND) 1.3.1.1 Call Forwarding (FWD)/Do Not Disturb (DND)—SUMMARY Description When an extension user cannot answer calls (e.g., he is busy, or not at his desk), it is possible to forward or refuse calls using the following features: 1) Call Forwarding (FWD) 2) Do Not Disturb (DND) 1. FWD Extensions and incoming call distribution groups can forward their incoming calls to preset destinations. (→ 1.3.1.2 Call Forwarding (FWD)) 2. DND Callers to an extension will hear a tone to inform them that the extension user is not available. (→ 1.3.1.3 Do Not Disturb (DND)) 3. FWD/DND Button, Group FWD Button The FWD/DND fixed button, or a customised flexible button, can display the FWD/DND setting status of the extension. (→ 1.3.1.4 FWD/DND Button, Group FWD Button) Conditions • FWD and DND are set for intercom calls (including doorphone calls), and trunk calls (including a call from an extension that placed a trunk call on a consultation hold) separately.

70 Feature Guide 1.3.1.2 Call Forwarding (FWD) Description Extensions and incoming call distribution groups can forward their calls to preset destinations. There are several different types of forwarding, and the circumstances under which the calls are forwarded for each type differ as follows: Depending on the type of incoming intercom or trunk calls, it is possible to set a different destination for each. Type Circumstance All Calls Any time Follow Me: When an extension user fails to set this feature before leaving the desk, this feature can be set from the destination extension. Busy When the extension user's line is busy. No Answer When the extension user does not answer within a preprogrammed time. Busy/No Answer When the extension user's line is busy or the user does not answer within a preprogrammed time. Intercom Calls to Extension Trunk Calls to Extension Forwards to Another Extension Intercom Calls to Extension Available Forwarding Type: Forwards to Outside Party Extension Intercom Calls to Incoming Call Distribution Group Trunk Calls to Incoming Call Distribution Group Forwards to Another Extension Forwards to Outside Party Available Forwarding Type: All Calls Incoming Call Distribution Group All Calls Busy No Answer Busy/No Answer

Feature Guide 71 [Available Destinations] Conditions [General] • FWD for Trunk Calls/Intercom Calls The extension user can set the FWD feature for trunk calls, for intercom calls, or for both. • FWD from Incoming Call Distribution Group (Group FWD) COS programming determines the incoming call distribution groups that can use this feature. • FWD to Trunk COS programming determines the extensions or incoming call distribution groups that can forward calls externally. The original extension's TRS/Barring and ARS still apply to the forwarded call. • Trunk Call Duration The duration of a trunk call can be restricted by a system timer. Trunk call duration is assigned separately for calls between an extension user and an outside party, and calls between two outside parties. If the timer expires, the line will be disconnected. (→ 1.11.8 Trunk Call Limitation) Destination Availability Condition for Original Extension/ Incoming Call Distribution Group Wired Extension (PT/SLT/ISDN Extension/T1- OPX) Only available when FWD to extension is allowed through COS programming.* PS Incoming Call Distribution Group PS Ring Group – Floating Extension no. for SVM – VM Group (DTMF/DPT) – External Pager (TAFAS) – DISA Only available for incoming trunk calls. Incoming intercom and doorphone calls cannot be forwarded to a DISA floating extension number. Analogue/ISDN Remote Maintenance – Idle Line Access no. + Phone no. Only available when FWD to trunk is allowed through COS programming. Trunk Group Access no. + Trunk Group no. + Phone no. Other PBX Extension (TIE with no PBX Code) – Other PBX Extension (TIE with PBX Code) Only available when FWD to trunk is allowed through COS programming. *: If an extension user is not permitted by COS to call a certain extension (→ 1.1.2.2 Internal Call Block), the FWD feature will not function if that extension is set as the forwarding destination.

72 Feature Guide • Multiple FWD Calls can be forwarded up to four times. The following forwarding features are counted as Multiple FWD: – FWD—Busy or Busy/No Answer (when the destination extension is busy), or All Calls – Idle Extension Hunting—Overflow – Intercept Routing—Busy/DND (when the destination extension is busy or in DND mode) – Incoming Call Distribution Group—Overflow In the above illustration, forwarding stops at extension E. However, forwarding can go farther in the following cases: – If a destination extension rings, and then the call is redirected to the forward destination by the FWD—No Answer or Busy/No Answer feature. – If a destination extension rings, and then the call is redirected to the intercept destination by the Intercept Routing—No Answer feature. – If a call waits in a queue of an incoming call distribution group, and then the call is redirected to the overflow destination by the Queuing Time Table. (→ 1.2.2.4 Queuing Feature) In the above cases, the forwarding counter resets to zero, and the call can be forwarded up to four times again from the destination extension described above. • Boss & Secretary feature It is possible to call the original extension from the destination extension regardless of the forward setting. • Message Waiting While calls are forwarded, Message Waiting information is not forwarded. The Message button light turns on at the originally called extension. (→ 1.19.1 Message Waiting) • Idle Extension Hunting Idle Extension Hunting applies to calls forwarded to a busy extension in an idle extension hunting group.

74 Feature Guide 1.3.1.3 Do Not Disturb (DND) Description An extension user can make use of the DND feature. If this feature is set, calls will not arrive at the extension, but will arrive at another extension using the Idle Extension Hunting feature (→ 1.2.1 Idle Extension Hunting) or the Intercept Routing—Busy/DND feature (→ 1.1.1.6 Intercept Routing). When a destination cannot be found, the calling extension will hear the DND tone, while the calling outside party will hear a busy tone. Conditions • DND for Trunk Calls/Intercom Calls The DND feature can be set for trunk calls, for intercom calls, or for both of them by the extension user. • DSS button in DND Mode The DSS button light will turn red if the assigned extension has set DND. • DND Override An extension in DND mode can be called by other extension users who are allowed to override DND in their COS. • Paging DND It is programmable whether the PBX pages extensions in DND mode through system programming. (→ 1.15.1 Paging) • Intercept Routing—Busy/DND If a call arrives at an extension in DND mode, the call can be redirected to a preprogrammed destination by the Intercept Routing—Busy/DND feature. • Idle Extension Hunting While searching for an idle extension within an idle extension hunting group, any extension that has DND set will be skipped. The call will go to the next extension in the group, not the Intercept Routing— Busy/DND destination. • If (1) a trunk call via the ELCOT, LCOT, or T1 (LCOT/GCOT) card arrives at an extension in DND mode and (2) the Intercept Routing—Busy/DND destination is not available and (3) there is no available extension in the idle extension hunting group, then the original extension in DND mode will ring. • Calls from a doorphone arrive at the extension even when the extension is in DND mode.

Feature Guide 77 FWD/DND Setting by Fixed FWD/DND button Pressing the fixed FWD/DND button in idle status allows the extension user to set the following items for FWD/DND: • FWD/DND for trunk calls The FWD/DND status for trunk calls to that extension can be switched temporarily without clearing the FWD destination. During setting, the LED of the button shows the current trunk call FWD/DND status. The forwarding type and destination for trunk calls can also be set. • FWD/DND for intercom calls The FWD/DND status for intercom calls to that extension can be switched temporarily without clearing the FWD destination. During setting, the LED of the button shows the current intercom call FWD/DND status. The forwarding type and destination for intercom calls can also be set. • FWD—No Answer timer The length of time until unanswered calls are forwarded can be modified. This setting is applied to both intercom and trunk call forwarding. • FWD for Virtual PS If the extension is the first registered extension in an Incoming Call Distribution Group, the extension user can set the FWD destination and forwarding status (on/off) for up to 4 virtual PSs preregistered to the group. (→ 1.25.6 Virtual PS) These settings are only available when FWD/DND buttons are set through system programming to FWD/ DND Setting mode. Conditions • When FWD/DND buttons are set to FWD/DND Cycle Switch mode, pressing the FWD/DND button cycles the FWD/DND setting. In this mode, when intercom calls are set to be handled differently from trunk calls (forwarding type, forward destination, DND on/off): a) in idle mode, the light patterns of the FWD/DND—Both button (including FWD/DND button [fixed button]) and the Group FWD—Both button will indicate the setting for either trunk calls or intercom calls, but not both. b) the FWD and DND icons on a PS display reflect the settings for trunk calls only. c) pressing the FWD/DND—Both button (including FWD/DND button [fixed button]) or the Group FWD—Both button will be ignored. • When both the FWD and DND features are assigned simultaneously, pressing the button changes the settings as follows: • A FWD/DND button customised on a flexible button is always in FWD/DND Cycle Switch mode, and the mode cannot be changed.

Feature Guide 91 1.5.4.3 Account Code Entry Description An account code is used to identify outgoing trunk calls for accounting and billing purposes. The account code is appended to the SMDR call record. If, for example, a firm uses an account code for each client, the firm can determine what calls were made for the client, and can submit a bill to the client according to the client's account code on the SMDR call record. There are two methods of entering account codes as follows: One of the methods is selected for each extension on a COS basis. Conditions • An account code can be stored into Memory Dialling (e.g., One-touch Dialling). • Account Button A flexible button can be customised as the Account button. The Account button is used in place of the feature number for entering an account code. This button is useful because it can be used at any time, while feature number entry is allowed only when hearing a dial tone before seizing a trunk. • Extension users can enter an account code at any time during a call, including after the call has been disconnected and a reorder tone is heard. However, if an account code is entered after there is no longer a reorder tone, the call will not be stored in the SMDR record. • If more than one account code is entered, the code entered last is printed out on SMDR. • Even in Forced mode, emergency numbers can be dialled out without an account code. (→ 1.5.4.2 Emergency Call) • PT users can also enter an account code for incoming trunk calls during a conversation. • Verification Code Entry To identify who made a trunk call for accounting and billing purposes, a verification code is used. This code can be used at any extension.

Feature Guide 93 1.5.4.4 Dial Type Selection Description The dialling mode (rotary or tone) can be selected for each analogue trunk through system programming regardless of the originating extension (under contract with the telephone company). There are the following modes: Conditions • Pulse to Tone Conversion It is possible for an extension user to temporarily switch from Pulse mode to DTMF mode so that the user can access special services such as computer-accessed long distance calling or voice mail services. To switch to DTMF mode, wait for a preprogrammed time period (Default: five seconds) after the trunk is connected, or press . This feature works only on trunks set to Pulse mode. DTMF mode cannot be changed to Pulse mode. • It is possible to select the pulse rate for a trunk port that has been set to Pulse mode. There are two pulse rates: Low (10 pps) and High (20 pps). • It is possible to assign the minimum duration of the DTMF signal sent to a trunk port that has been set to DTMF mode.

Feature Guide 95 1.5.4.5 Reverse Circuit Description A circuit in the PBX can detect the reverse signal from the telephone company when an extension user tries to make a trunk call. This detects the start (a called party goes off-hook) and end (the called party goes on- hook) of an outgoing trunk call. When a trunk call is received, the circuit can also detect the reverse signal after an outside caller goes on-hook. If Reverse Circuit Detection is disabled, the total duration of the call is not accurately recognised by the PBX. The duration of a call can be verified on SMDR using this feature (→1.26.1 Station Message Detail Recording (SMDR)). It is possible to select whether the PBX detects the reverse signal for outgoing trunk calls only, or for both outgoing and incoming trunk calls, or for no trunk calls (detection disabled) through system programming. Conditions • This feature is not available for the following ELCOT or LCOT cards: KX-TDA6181AL (ELCOT16) KX-TDA0181AL (LCOT16) KX-TDA0180AL (LCOT8) Programming Manual References PC Programming Manual 2.7.11 [1-1] Slot—LCO Port—Reverse Detection PT Programming Manual [415] LCOT Reverse Circuit

96 Feature Guide 1.5.4.6 Trunk Busy Out Description The PBX can monitor the loop current sent through analogue trunks, preventing users from seizing trunks where a loop current is not detected. When loop currents are not detected, trunks are set to Busy Out status, and become unable to make or receive calls. A trunk in Busy Out status cannot be used for making calls as a TIE line, as part of a trunk group, or with the ARS feature, and cannot receive trunk calls. If a user tries to seize a trunk set to Busy Out status, the user will hear a reorder tone. This is useful if some or all trunks are occasionally unavailable because of problems with the external telecommunications environment. Conditions • This feature is not available for the following LCOT cards: KX-TDA0181NE (LCOT16) KX-TDA0180NE (LCOT8) KX-TDA0183NE (LCOT4) KX-TDA3180NE and KX-TDA3180AL (LCOT4) KX-TDA3183NE and KX-TDA3183AL (LCOT2) • Loop current detection is performed on active trunks whenever the trunk is seized and/or at fixed intervals. • When a trunk is in busy-out status, loop current detection is performed at fixed intervals, returning the trunk to in-service status once a loop current is detected. An extension assigned as the manager can manually change the trunk back to in-service status. • Trunk status changes are recorded in the error log of the PBX. • Busy Out status is maintained even when the PBX is reset.

98 Feature Guide 1.5.4.8 Host PBX Access Code (Access Code to the Telephone Company from a Host PBX) Description This PBX can be installed behind an existing PBX (host PBX) by connecting the extension ports of the host PBX to the trunk ports of this PBX (behind PBX). A Host PBX Access code is required for the behind PBX to access the telephone company (e.g., to make outside calls) through the host PBX. The Trunk access number of the host PBX should be stored as a Host PBX Access code on a trunk group of the behind PBX. A preprogrammed Pause time will be automatically inserted between the user dialled Host PBX Access code and the subsequent digits (1.5.4.7 Pause Insertion). [Example] Note "0" should be assigned as a Host PBX Access code for trunk group (TRG) 1 of the behind PBX. Dials "9-0-01-23-4567".

Feature Guide 99 Conditions • TRS/Barring TRS/Barring checks only the dialled telephone number excluding the Host PBX Access code when accessing the telephone company through the host PBX. (→ 1.9.1 Toll Restriction (TRS)/Call Barring (Barring)) • ARS A pause is not automatically inserted between the user-dialled access code and the subsequent digits when the ARS mode is enabled. (1.10.1 Automatic Route Selection (ARS)) • SMDR The dialled number including the Host PBX Access code will be recorded on SMDR only if the modified number setting is selected in the ARS setting for SMDR. • When a Host PBX Access code is assigned to a trunk group, calls to extensions of the host PBX are not recorded on SMDR. • A Host PBX Access Code can be used to record only long distance calls on SMDR when a trunk port is connected directly to the telephone company (not a host PBX). This is allowed when the long distance code (e.g., “0”) is assigned as the Host PBX Access code. All local calls (e.g., calls that do not require a “0” to be dialled first) are treated as extensions of the telephone company and do not get recorded on SMDR, because in this case this PBX recognises the telephone company as the host PBX. Therefore, only long distance calls are recorded on SMDR.
