CRS-170A – Top and Antenna Side Features

MN/CRS170A.IOM Introduction Revision 14 1–5 1.3 Functional Description The CRS-170A performs the Tx and Rx coaxial switching required for redundant modem operation with an outdoor BUC and LNB. The Tx (transmit) side switches four modem output signals that are multiplexed onto the transmit coaxial cable: • 950-2250 MHz L-band transmit RF; • 10 MHz BUC frequency reference; • 600 KHz BUC FSK control and status communication; • BUC DC power supply. The Rx (receive) side of the switch uses both power dividers and relays to provide the redundant modem interface for three signals multiplexed onto the LNB coaxial cable: • 950-2250 MHz L-band receive RF from LNB; • 10 MHz frequency reference to LNB; • DC power supply to LNB. 1.3.1 Switch / Modem Operation The CRS-170A is configured with two modems to form a complete 1:1 redundant modem system. Within the CRS-170A, a redundancy controller continually monitors the status of faults for both modems to determine which modem should be Online and Offline. The control cables between the modems and the CRS-170A include four signal groups: • First, serial full-duplex communication lines are routed from one modem to the other modem via the CRS-170A. Using these lines, this Online unit can interrogate the Offline unit at regular intervals to determine its configuration. If a difference in configuration is detected, the Online unit will reconfigure the Offline unit so that the configurations are always synchronized. This process is entirely automatic – if the Offline unit is replaced, it does not have to be manually reprogrammed to match the Online unit. • Second, the Modem’s Unit, Tx and Rx faults signals from both modems are routed to the CRS- 170A. This allows the redundancy controller to always know the health status of both modems. • Third, the online/offline signals are routed from the CRS-170A to each modem. Based on the modem faults, the CRS-170A will determine which modem should be Online and Offline. In the event that both modems indicate faults through some malfunction, the CRS-170A switch will select, by default, Modem ‘A’. • Fourth, +12V is routed from each modem to the CRS-170A for operational power. This power from both modems is diode OR’d so that the switch remains active if power is lost from one of the modems. Mode Switches – The Mode DIP switches, located on the antenna side of the CRS- 170A, allow the switch to operate in two different modes – Normal (Intelligent Controller) Mode and SDM-300L/CDM-600L (Dumb Controller) Mode: • Use Normal (Intelligent Controller) Mode for the CDM-625A or CDM- 625, H64/H32/H16/H8 Heights Remote Gateway, Advanced VSAT CDM-850 or CDM-840, CDM-760, CDM-750, CDM-710GL, CDM-710, CDM- 700, and CDM570L/AL modems.

MN/CRS170A.IOM Introduction Revision 14 1–6 • Use SDM-300L/CDM-600L (Dumb Controller) Mode for SDM-300L and CDM-600L (CLM-9600L) modems. IF Switching – The CRS-170A provides L-Band redundancy, but when switching occurs, it accommodates more than just the L-Band signals: • On the Tx side, it switches the Tx L-Band signal, the 10 MHz reference to the BUC, DC power to the BUC and, on CDM-570L modems, FSK signaling to the BUC. • On the Rx side, it switches the 10 MHz reference to the LNB, and DC power to the LNB. The Rx L- Band signal from the LNB is split in a power divider to continuously drive both the Online and Offline demodulator. The Offline demodulator can then maintain lock so that it is ready to quickly assume Online status for receive traffic when a switchover is required. Data Switching is accomplished inside each modem, in the data interface itself. A ‘Y’ cable connects both the Online unit and the Offline unit to the terrestrial data source. Transmit data drives both modems in parallel so that the Backup modulator is always ready to come Online. Termination impedance for the modem line receivers is active in the Online unit. On the Rx side of the interface, TRI- STATE® control of the Offline unit line drivers keeps the Offline unit from interfering with the Rx data traffic. Send timing output from the Offline unit is also TRI-STATE®1. The Offline Modem holds its Rx terrestrial data in TRI-STATE® as commanded by the CRS-170A Switch. Because of this, it is very important to power down the Offline Modem before disconnecting the modem from the Switch. Manual Switching is user-enabled locally via the Online unit; locally using the modem’s front panel, or remotely using serial remote control or the modem’s Web Server (HTTP) Interface. You must control Automatic Switching Selection via the Online unit. Use the CRS-170A Switch Conditions Unit+Tx and Unit+Rx DIP switches, located on the antenna side of the CRS-170A, to configure the conditions that cause an automatic switchover. These settings provide a great deal of flexibility in the operation of the switch: you can select between Modem Unit faults only; Modem Unit faults or Receive Traffic faults; Modem Unit faults or Transmit Traffic faults; or all three. Section 4.10 CRS-170A DIP Switch Settings Two green LEDs are located on the antenna side of the CRS-170A. They provide a visual identifier for the Online unit. With the ‘bridging’ architecture of the CRS-170A (whereby identical terrestrial data traffic signals are routed to both Online and Offline units), the redundancy controller can avoid unnecessary switchovers. By examining the fault status of both modems, it can infer if the fault is external to the system. For example, you have configured the CRS-170A to switch following Unit Faults or Transmit Traffic Faults, and your modems have been configured for external clock operation. Now, suppose that the external equipment (network, multiplex, router, etc.) fails – both the Offline and Online units will now show a Transmit Traffic fault (No Clock Detected from Terrestrial Port).

MN/CRS170A.IOM Introduction Revision 14 1–7 will see that both faults have occurred at the same time (i.e., within a 0.5 second window), and infers that the fault is external. Therefore, no unnecessary switchover is initiated. 1.3.2 1:1 IP Redundancy Data Switching 1.3.2.1 Managed Switch Mode for CDM-625A or CDM-625, Heights Remote Gateway, Advanced VSAT CDM-850 or CDM-840, CDM-760, CDM- 750, CDM-710GL, CDM-710, or CDM-700 A standard, user-provided Ethernet Layer 2 Switch is needed if any of the modems listed here are configured for Managed Switch Mode (also known as “Ethernet Bridge Mode”) terrestrial traffic. A Layer 2 Switch is designed to limit the traffic that egresses each port by only sending Ethernet packets out the port that the destination network device is located. The switch maintains a table - known as the dynamic Content-Addressable Memory (CAM) table - that maps MAC addresses to switch ports. When a packet arrives, in which an entry for that specific destination MAC is unknown to the switch, it sends the packet out all ports and waits for response packets in an attempt to identify which port that particular MAC resides. Once the device responds, the switch is able to map the MAC to the port in the CAM table. Any new arriving packets destined for that MAC address will be forwarded only out the port identified in the CAM table. Most switch CAM tables do have a flush or timeout value, but is normally set to a very high number to limit the amount of times the switch has to broadcast a packet out all ports. It is also important to note that CAM entries for a specific port are cleared when a port link goes down.

Both modems are operational – Modem ‘A’ is Online and connected to Port 4 of the Layer 2 Switch. Modem ‘B’ is Offline and connected to Port 3 of the Layer 2 Switch, but the Ethernet link is not active because only the Online unit will have an active Ethernet data interface. Also, Local PC ‘A’ is connected to Port 1 of the Layer 2 Switch. When Ethernet traffic is sent from Local PC ‘A’ across the satellite link to remote PC ‘B’, the Layer 2 Switch will “learn” the MAC addresses of both PCs and will have these dynamic entries in its CAM Table: Port 1 MAC 00-00-00-00-00-11 (Local PC ‘A’) Port 3 No entries, port down Port 4 MAC 00-00-00-00-00-22 (Remote PC ‘B’) As shown in Figure 1-5, in the event of a fault on the Online unit ‘A’, the following will occur: • Modem ‘A’ goes offline and disables its Ethernet data interface. • Simultaneously, Modem ‘B’ goes online and enables its Ethernet data interface. • Layer 2 Switch ‘A’ senses that Port 4 is no longer active and clears the CAM table entries for that port. • When the next Ethernet packet from Local PC ‘A’ destined for Remote PC ‘B’ arrives at Switch ‘A’, there is no CAM entry for the PC ‘B’ MAC, so it will be broadcast to all active ports. • When the next Ethernet packet from Remote PC ‘B’ arrives at Switch ‘A’, Switch ‘A’ dynamically adds the PC ‘B’ MAC to the CAM table for Port 3.

MN/CRS170A.IOM Introduction Revision 14 1–9 Figure 1-5. 1:1 IP Redundancy Managed Switch Mode – Switchover for CDM-625A or CDM-625, Heights Remote Gateway, Advanced VSAT CDM-850 or CDM-840, CDM-760, CDM-750, CDM-710GL, CDM-710, or CDM-700 Note the following: 1) The Managed Switch Mode method of redundancy is intended to be equivalent to pulling the Ethernet cable from one port and putting it into a different port on the same switch. 2) For the CDM-625A or CDM-625 modems, you may configure one of the modem’s four available 10/100 Ethernet ports for M&C Ethernet. As configured in Dedicated Management Port Mode, when the modem is offline the M&C-designated port remains functional and available for operation, while the three remaining ports are unavailable. Otherwise, if none of the 10/100 Ethernet ports are reserved for M&C operation; all four ports become unavailable when the modem is offline. This configuration must be enabled on both modems. See the CDM-625A or the CDM-625 Advanced Satellite Modem Installation and Operation Manual (CEFD Part No. MN-CDM625A or MN-CDM-625) for instructions to configure one of the four 10/100 Ethernet ports for each modem for remote Ethernet M&C. Dedicated Management Port Mode is not configurable for use when the optional IP Packet Processor is installed and enabled. With the IP Packet Processor enabled, as a means to avoid Ethernet Networking Loops, only one of the CDM-625A or CDM-625’s four 10/100 Ethernet ports is used for each modem at any given time. 3) For CDM-760, CDM-750, CDM-710GL, CDM-710, or CDM-700 modems, when the modem is offline, although all GigE port(s) are unavailable, the M&C Ethernet port remains functional and available for operation. 4) Installation must use a true switching device, not a hub device.

MN/CRS170A.IOM Introduction Revision 14 1–10 1.3.2.2 Router Mode For CDM-625A or CDM-625 WITH Optional IP Packet Processor All configuration changes can only be made to the Online unit and will require you to “Save Parameters to permanent storage” to ensure the configuration change is also applied to the Backup Modem. For the CDM-625A or CDM-625 with the optional IP Packet Processor installed and enabled and the configuration set for Router Mode, you need to provide an external Ethernet switch. In Router Mode, both modems must be assigned a unique Management IP address on the same subnet (172.18.10.21/24 and 172.18.10.22/24 as shown in Figure 1-6 and Figure 1-7). This is used to share the parameters file. A Traffic IP address on the subnet must also be assigned (172.18.10.20/24) in the Online unit. The Traffic IP Address must be different from either Management IP Address. Whichever modem is Online will assume the Traffic IP. When there is a switchover to the backup modem, this modem will now assume the Traffic IP. Figure 1-6. CDM-625A or CDM-625 1:1 IP Redundancy Router Mode – ‘A’ Online

MN/CRS170A.IOM Introduction Revision 14 1–12 1.3.2.3 Managed Switch or Router Modes for CDM-570L/AL WITH Optional IP Module or Packet Processor • Do not use the M&C Ethernet port (bottom RJ-45 connector) when the optional IP Module is installed. • All configuration changes can only be made to the Online unit and will require you to “Save Parameters to permanent storage” to ensure the configuration change is also applied to the Backup Modem. Managed Switch (Ethernet Bridge) Mode: For the CDM-570L/AL in Managed Switch Mode (also known as “Ethernet Bridge Mode”) you MUST use an external Ethernet hub to insure that traffic will continue after a switchover. If an Ethernet switch is used, there could be a several minute outage while the Ethernet Switch “re-learns” the correct output Ethernet port. Using a “dumb” Ethernet hub allows LAN- to-WAN traffic to continue even after a switchover occurs since both modems will be receiving the LAN traffic. In Managed Switch Mode, both modems should be assigned a unique Management IP address on the same subnet in order to share the parameter file. Router Mode: For the CDM-570L/AL in Router Mode, you should use an external Ethernet switch. Router mode does not require a “dumb” hub as with Managed Switch Mode and, for performance reasons, an Ethernet switch is highly recommended. In Router Mode, both modems must be assigned a unique Management IP address on the same subnet (172.18.10.21/24 and 172.18.10.22/24 as shown in Figure 1-8 and Figure 1-9). This is used to share the parameters file. A Traffic IP address on the subnet must also be assigned (172.18.10.20/24) in the Online unit. Whichever modem is Online will assume the Traffic IP. When there is a switchover to the backup modem, this modem will now assume the Traffic IP. As shown in Figure 1-9, the backup modem will also broadcast a “gratuitous ARP” that will tell all local devices to now associate a new MAC address for the Traffic IP 172.18.10.20. Each device will update their ARP tables and traffic will resume virtually instantaneously.

MN/CRS170A.IOM Introduction Revision 14 1–15 1.3.3 CRS-170A Operation with CDM-600L (CLM-9600L) and SDM-300L3 Modems The CDM-600L (CLM-9600L) and SDM-300L3 modems do not have built-in switching capability for the terrestrial data side of the link: • For the CDM-600L (CLM-9600L), 1:1 redundancy requires both a CRS-150 switch to act as controller and terrestrial data switch and a CRS-170A to perform the L-Band switching. The CRS-170A is required because the CRS-150 RF switching is limited to the L-Band band, and will not handle the high current BUC power supply multiplexed onto the transmit coaxial cable. • Similarly, the SDM-300L3 requires an SMS-301 switch together with the CRS-170A. In both cases, the CRS-170A is controlled by the supporting data switch, and places the ‘A’ or ‘B’ modem RF Online to match the data switch state. The CDM-600L (CLM-9600L) modems supply redundant power to the CRS-170A through the CRS-150. The SMS-301 itself has redundant power supplies, and feeds power to the CRS-170A through the control cable. Online/Backup Modem configuration matching is provided by the CRS-150 controller communication with the CDM-600L (CLM-9600L) modem. The SMS-301 does not automatically configure the Backup Modem. Operation with two CDM-600L (CLM-9600L) modems requires an additional CRS-150 1:1 switch for terrestrial data switching and 1:1 control, while operation with two SDM-300L3 modems requires an additional SMS-301 1:1 switch to handle terrestrial data and control. Thus, there are three functional configurations for the CRS-170A. 1.3.3.1 Operation with CDM-600L (CLM-9600L) Modems and CRS-150 Switch CRS-150 1:1 Redundancy Switch Installation and Operation Manual (CEFD P/N MN/CRS150.IOM) THE CRS-150 IS AN ACCESSORY PRODUCT DESIGNED SPECIFICALLY FOR THE COMTECH EF DATA CDM-600 AND CDM-600L (CLM-9600L) MODEMS, AND MUST NOT BE USED WITH ANY OTHER EQUIPMENT. Figure 1-10. CRS-150 1:1 Redundancy Switch The CRS-150 1:1 Redundancy Switch (Figure 1-10) connects to Online and Backup modems, monitors the fault status of these units, and controls the routing of data to and from the units. IF signals, 10MHz

MN/CRS170A.IOM Introduction Revision 14 1–16 reference signals, DC power for the BUC and LNB, and FSK signaling to the BUC are switched in the CRS- 170A under control of the CRS-150. In the case of an equipment failure, automatic switching takes place to protect the traffic circuit. At the heart of the CRS-150 is a Controller State Machine that is responsible for fault monitoring and control of switching functions – it is implemented in a Complex Programmable Logic Device (CPLD). The CRS-150 derives its operating power from the Online and Backup modems via extra power-carrying wires in the data cable from each modem. Similarly, the CRS-170A derives its +12V power from both modems through 'Y' cable connection to the same cables. The required online and offline control signals are also included in these cables. A diode sharing arrangement with a current sharing circuit ensures that power is taken equally from the two modems in normal operation. In the event that one of the two units is removed, however, the remaining modem can supply all current requirements. The modems supply +12 volts DC (at a combined total of 400 mA max) and -12 volts DC (at a combined total of 120 mA max). Maximum power consumption occurs in a serial LVDS mode at maximum data rate (20 Mbps). Power consumption in EIA-232 modes is approximately 40% of the maximum values. The modem employs electronic fuses that prevent excessive current from being drawn by the CRS-150 should an anomalous condition occur. Transmit Clock and Data signals entering the CRS-150 via the Data Interface are buffered and fed to both modems simultaneously; this parallel feed ensures that the Backup unit sees the same traffic conditions as the ONLINE unit. Rx Data and Clock signals coming from the ONLINE unit are routed through signal relays to the Data Interface. In the event that a switchover occurs, these relays switch so the Backup unit then supplies the Data and Clock signals. As only one modem in the pair (the Online unit) is permitted to transmit its IF carrier signal at any one instant, the Backup unit is forced to disable its Tx carrier by asserting the Tx Carrier Off signal at the Data Interface. Additionally, the CRS-170A provides further isolation and security by using an RF relay within the unit. The Rx IF signal is fed to both modems simultaneously through the power divider in the CRS-170A. This divider introduces a loss of approximately 3.5 dB but, given the wide dynamic range of the demodulator in the CDM-600L (CLM-9600L), this is not considered to be a problem. The advantage of this scheme is that the demodulators in both Online and Backup units are locked, and therefore if a switchover does occur, there will be no delay while waiting for the demodulator to acquire lock. Fault status information is fed from the Online and Backup modems via the Data Interface connector. Based on the fault status, the Controller State Machine in the CRS-150 decides whether the ‘A’ or ‘B’ unit is to be the ONLINE unit. It asserts a control signal to the Backup unit, which mutes its Tx IF carrier and simultaneously indicates to the microcontroller within the Backup unit that the unit is no longer ‘Online’. Consequently, the ‘Online’ LED on the front panel of the Backup Modem is extinguished and the Backup status is also reported over the remote control bus so an external M&C system can determine the state of the redundancy system. At the same time, a green LED will illuminate on the front of the CRS-150 to indicate whether the ‘A’ or ‘B’ unit is Online, and the green LEDs on the antenna side of the CRS-170A will indicate the same status.

MN/CRS170A.IOM Introduction Revision 14 1–17 Set the DIP switches on the CRS-170A antenna side to establish modem- specific operation. For the CDM-600L (CLM-9600L), place the Mode switch in the SDM-300L/CDM-600L (Dumb Controller) position and push the Switch Condition switches to the OFF position. Section 4.10 CRS-170A DIP Switch Settings 1.3.3.2 Operation with SDM-300L3 Modems and SMS-301 Switch SMS-301 Redundancy Switch Installation and Operation Manual (CEFD P/N MN/SMS301.IOM) Figure 1-11. Comtech EF Data SMS-301 1:1 Redundancy Switch The SMS-301 1:1 Redundancy Switch (Figure 1-11) is modified from the standard version that operates with 70/140 MHz IF SDM-300A modems. All operation as a 70/140 MHz modem switch applies except that the RF switching is done in the CRS-170A. The BNC IF connectors are replaced by Type ‘N’ connectors, as BNC connectors and internal switching are not suitable for L-Band operation. Signals on the ‘J14 | Status/Faults’ connector are modified to provide +12VDC power output and A/B switch control outputs to the CRS-170A. The SMS-301 has its own redundant power supplies, so the CRS-170A receives redundant power. Operation here is similar to operation of the CRS-150 1:1 Redundancy Switch with CDM-600L (CLM- 9600L) Online and Backup modems. The SMS-301 operates as the principal switch and controller, with the CRS-170A providing the required switching for L-Band signals, references, and power supplies that the SMS-301 cannot handle. The SMS-301 connects to the Online and Backup SDM-300L3 modems, monitors the fault status of these two units, and controls the routing of data to and from the units. IF signals, 10MHz reference signals, DC power for the BUC and LNB, and FSK signaling to the BUC are switched in the CRS-170A under control of the SMS-301. In the case of equipment failure, automatic switching takes place to protect the traffic circuit. Set the DIP switches on the CRS-170A antenna side to establish modem- specific operation. For the SDM-300L3, place the Mode switch in the SDM-300L/CDM-600L (Dumb Controller) position and push the Switch Condition switches to the OFF position. Section 4.10 CRS-170A DIP Switch Settings

Optional KT/11708 Switch Mounting Kit You may also mount the module into a 1RU space at the front or rear of the rack enclosure that houses the modems. The optional Comtech EF Data KT/11708 Mounting Panel Kit is available for this purpose. As shown in Figure 2-1, the module can be installed vertically or horizontally to the kit’s slotted mounting panel. User-supplied screws are then required to secure the panel to the rack enclosure threaded mounting rails. CAUTION: PROPER GROUNDING PROTECTION IS REQUIRED. The equipment must be connected to the protective earth connection at all times. It is therefore imperative that the Switch and its paired modems are properly grounded – using the ground stud provided on the Switch antenna side panel and the ground studs located on the modem rear panels – during installation, configuration, and operation.

AND PINOUTS 3.1 Cabling Connection Types The cable and connector types described in this section are commonly used in many Comtech EF Data products. Each cable type is typically dedicated to a specific mode of operation. The CRS-170A L-Band 1:1 Redundancy Switch and its compatible Traffic and Redundant Modems may not use all of these connector types. The European EMC Directive (EN55022, EN50082-1) requires that you use properly shielded cables for DATA I/O. These cables must be double-shielded from end-to-end, ensuring a continuous ground shield. 3.1.1 Coaxial Cable Connections Figure 3-1 show the coaxial cables (plugs) and their mating connectors (jacks/sockets) that Comtech EF Data uses with their products: ‘BNC’, ‘TNC’, ‘N’, ‘F’, and ‘SMA’.

CONFIGURATION 4.1 Overview To avoid damage either to the modem pair or the CRS-170A switch, it is important that you follow this sequence of configuration: • First, configure both modems for 1:1 redundant operation as directed in this chapter. This chapter organizes the modem-specific sections and any specific interface configuration examples as follows: For Product... See Chapter Section CDM-625A or CDM-625 4.2 H64, H32, H16, or H8 Heights Remote Gateway 4.3 Advanced VSAT CDM-850 or CDM-840 4.4 CDM-760 or CDM-750 4.5 CDM-570L or CDM-570AL 4.6 CDM-710GL, CDM-710, or CDM-700 4.7 CDM-600L (CLM-9600L) 4.8 SDM-300L3 4.9 • Then, once you properly configure both modems for 1:1 redundant operation, set the DIP switches on the CRS-170A to the correct modem selection. See Sect. 4.10 CRS-170A Switch DIP Settings for details. • Finally, once you properly configure both modems and the DIP switches, connect the control and IF cables between the powered OFF modems and switch. See Chapter 5. CABLES and CONNECTIONS for details.

MN/CRS170A.IOM Modem and Switch Configuration Revision 14 4–3 4.2 Configure the CDM-625A or CDM-625 for 1:1 Redundancy • CDM-625A Advanced Satellite Modem Installation and Operation Manual (CEFD P/N MN-CDM625A) • CDM-625 Advanced Satellite Modem Installation and Operation Manual (CEFD P/N MN-CDM625) The CDM-625A or CDM-625 Advanced Satellite Modem automatically detects if it is connected to a 1:1 redundancy system – the steps required to configure both modems are therefore minimal, with some exceptions: If the CDM-625A or CDM-625 has the optional IP Packet Processor installed and enabled, 1:1 Redundancy is controlled from the CDM-625A or CDM-625 HTTP Interface Redundancy page. When both the traffic and backup modems are equipped with the optional IP Packet Processor and are connected to the CRS-170A L-Band 1:1 Redundancy Switch), there is no need to use the drop-down menu here, as Packet Processor Redundancy is enabled automatically. If you wish to operate either modem outside of the redundant setup as a standalone unit, use the drop- down menu to select Packet Processor Redundancy for that specific modem as Disabled. If terrestrial data is not Ethernet and CnC will not be used, then no modem 1:1 redundancy configuration is needed. Otherwise, if either applies, refer to the sections that follow. 4.2.1 CDM-625A or CDM-625 Remote User M&C Ethernet Interface 4.2.1.1 For CDM-625A or CDM-625s without the Optional IP Packet Processor See the CDM-625A or CDM625 Advanced Satellite Modem Installation and Operation Manual (CEFD P/N MN-CDM625A or MN-CDM625) for instructions to configure one of the four 10/100 Ethernet ports as the Dedicated Management Port for remote Ethernet M&C. TO AVOID ETHERNET NETWORKING LOOPS – If you configure more than one Ethernet port for Ethernet traffic, you must use separate Layer 2 switches unless the Layer 2 switch in use isolates these ports from one another. You may configure one of the CDM-625A or CDM-625’s four available 10/100 Ethernet ports for M&C Ethernet. As configured in Dedicated Management Port Mode, when the modem is offline the M&C- designated port remains functional and available for operation, while the three remaining ports are unavailable. Otherwise, if none of the 10/100 Ethernet ports are reserved for M&C operation; all four ports become unavailable when the modem is offline.

MN/CRS170A.IOM Modem and Switch Configuration Revision 14 4–4 4.2.1.2 For CDM-625A or CDM-625s Equipped With the Optional IP Packet Processor TO AVOID ETHERNET NETWORKING LOOPS – While in 1:1 Redundancy mode, with the optional IP Packet Processors enabled and both units operating in Managed Switch Mode, the Port 1 M&C Ethernet must be isolated from the Ethernet Traffic. Also, if you use more than one of the Traffic Ports (Ports 2, 3, or 4), you must use separate Layer 2 switches unless the Layer 2 switch in use isolates these ports from one another. You may not configure your modem for Dedicated Management Port Mode when the optional IP Packet Processor is installed and enabled. Under such functionality, in 1:1 redundancy Port 1 is available only for M&C on both modems, while Ports 2, 3, and 4 are disabled when a modem is in the Offline state. 4.2.2 Configure CDM-625A or CDM-625 Carrier-in-Carrier® for Redundancy Operation The Pre-Mapped Symbol Interface (PMSI) is associated with DoubleTalk® Carrier-in-Carrier®. It permits the modulator in a selected unit to provide a direct copy of its output (the outbound interferer) to the second modem. The other modem may then choose to take the PMSI signal and use it for its own CnC reference. In 1:1 redundancy, the PMSI is an EIA-485 multi-drop bus system where one device transmits and the other device on the multi-drop bus is configured to receive. If you use Carrier-in-Carrier® (CnC), you must configure the CnC control setting to Redundancy mode using the CDM-625A or CDM-625 front panel menus. Do these steps to configure the CnC control setting for CDM-625A or CDM-625 1:1 Redundancy: Step Task 1 From the modem front panel menu – Use the ◄► arrow and ENTER keys to select the PMSI control mode menu: SELECT: Configuration  CnC  PMSI-control CnC PMSI mode: Redundancy (Idle, Redundancy, Talk, Listen) () Use the ▲ ▼ arrow keys to select Redundancy, and then press ENTER. 2 You will now need to connect the two modems together via use of a 1:1 PMSI cable (note that this cable bypasses the CRS-170A). • Chapter 5.

MN/CRS170A.IOM Modem and Switch Configuration Revision 14 4–12 Because the modem automatically detects if it is connected to a 1:1 redundancy system, the steps required to configure both modems are minimal. Modem configuration, monitor and control are possible through local or remote means (Figure 4-4): • Local Control – Use the modem front panel to fully configure, monitor, and control the modem operation: o The LEDs indicate, in a summary fashion, the status of the modem. o The VFD (Vacuum fluorescent Display) is an active display showing two lines of 24 characters each. It produces a blue light with adjustable brightness. Nested menus display all available options and prompt you to carry out a required action. o The keypad comprises six individual keyswitches. The keys have a positive ‘click’ action that provides tactile feedback. Enter data via the keypad. Data, prompts, and messages are displayed on the VFD. • Serial Remote Control – Configuration, monitoring and control of redundant systems is possible via remote means over an RS-485 multi-drop bus using Windows Command-Line, where data is transmitted in asynchronous serial form using ASCII characters. • Ethernet Remote Control – Configuration, monitoring and control of redundant systems is possible via remote means over an Ethernet connection using the Telnet Command Line Interface (CLI) or the CDM-570L/A HTTP Interface. 4.6.1 CDM-570L or CDM-570AL Non-IP Redundancy Configuration Do these steps for setup of CDM-570L or CDM-570AL modems for 1:1 Redundancy, when the terrestrial data type is non-Ethernet (i.e. RS422, G.703). Step Task 1 Enable 1:1 Redundancy on both modems: • From the CLI Main Menu, press ‘E’ to open the 1:1 Redundancy Configuration page. o Press ‘R’ to toggle 1:1 Redundancy as [Enabled]. o Press ‘S’ to ““Save Parameters to permanent storage”. • Alternately, using the HTTP Interface ‘REDUNDANCY’ page: o Use the drop-down list in the 1:1 Redundancy Control section of this page to select Enabled. o Click [Submit] to save. If you submit any changes to this web page when the CDM-570AL optional IP Packet Processor is INSTALLED, you must also open the ‘Admin | Pap Save’ page and immediately click [Save PaP Parameters]. 2 Connect all cables to the modems and the CRS-170A. This includes the control cable, IF cable and data ‘Y’cables. Chapter 5. CABLES AND CONNECTIONS

MN/CRS170A.IOM Modem and Switch Configuration Revision 14 4–13 4.6.2 IP Redundancy Configuration Before continuing you must remember that, when you use the Command Line Interface (CLI), you can make configuration changes to the Online modem only. Make sure to press ‘S’ to “Save Parameters to permanent storage” after making any changes to an active CLI page. This ensures that the configuration change is also applied to the Backup modem. Do these steps for setup of a CDM-570L or CDM-570AL 1:1 IP Redundancy System: Step Task 1 Use a Layer 2 switch (preferred) or hub to establish an Ethernet connection between the two modems. 2 Before you connect the modems to the CRS-170A, you must first use the modem CLI to configure the following CDM-570L or CDM-570AL IP operation settings: • Disable 1:1 Redundancy operation – From the Main Menu, press ‘E’ to open the 1:1 Redundancy Configuration page. o Press ‘R’ to toggle 1:1 Redundancy as [Disabled]. • From the Main Menu, press ‘A’ to open the Administration page. o Press ‘W’ (Administration  Working Mode) and set both modems to the same Working Mode. o Press ‘F’ (Administration  Feature Configuration) and make sure to configure, using all applicable submenus, both modems to have the same IP-related operability and settings. 3 For each modem, use the CLI to enter a unique IP Address that is on the same subnet: • From the Main Menu, press ‘I’ to open the Interface Configuration page. • Press ‘E’ to open the Ethernet Interface page (Interface Configuration  Ethernet Interface): • Press ‘I’ to enter the IP Address. 4 Verify that you can ping from one modem to the other: • From the Main Menu, press ‘O’ to open the Operations and Maintenance page. • Press ‘G’ to open the Diagnostics page (Operations and Maintenance  Diagnostics): • Press ‘P’ and then enter the IP Address of the other modem in the redundant pair. 5 Re-enable 1:1 Redundancy operation – From the Main Menu, press ‘E’ to open the 1:1 Redundancy Configuration page. • Press ‘R’ to toggle 1:1 Redundancy as [Enabled]. 6 Power down both modems. 7 Connect the modems to the CRS-170A.

MN/CRS170A.IOM Modem and Switch Configuration Revision 14 4–19 4.10 CRS-170A DIP Switch Settings The ‘Switch Conditions’ DIP switches are set depending upon the type of Tx or Rx traffic conditions resultant of switchover. Some modems have additional settings or alarm masks that affect conditions – see your individual modem manual for detailed explanations. Comtech EF Data’s expansion of compatible product required a change in the labeling on the Antenna Side (towards the BUC and LNB) of the CRS-170A L-Band 1:1 Redundancy Switch. Figure 4-6 shows the change to the ‘Mode’ DIP switch labeling between the original and current (i.e., Rev. ‘A’ and later) production versions of the CRS-170A. Use these features to set the ‘Mode’ and ‘Switch Conditions’ controls: • See Table 4-1 for setting the ‘Mode’ DIP switches. These settings define product/switch compatibility. • See Table 4-2 for setting the ‘Switch Conditions’ DIP switches. These settings define the conditional switchover functions.

CONNECTIONS 5.1 Overview When assembling a Comtech EF Data 1:1 Redundancy System, in addition to purchasing the modem pair (one Redundant Modem, one Traffic Modem), you must also purchase a redundancy kit tailored to that modem choice. Each kit provides the CRS-170A L-Band 1:1 Redundancy Switch module, plus all cables and components required for interconnection of the redundant configuration to various interfaces (i.e., control, IF, and data). This excludes Ethernet operation, which requires user-provided cabling and Layer 2 switching. 1) The cables required between each modem and Switch should be of shielded, twisted- pair construction, with the grounded shield bonded to the back shell. All data cables should be wired correctly using the pinout and connection information as specified in Appendix A. CABLE DRAWINGS. 2) It is physically impossible to connect all available data interface solutions within a single 1:1 redundancy system at a given time. For example, when using the CDM-625A or CDM-625 in a 1:1 system, you are unable to establish an ASI interface together with a G.703 Unbalanced interface, or an EIA-422/232 interface together with an HSSI interface. The quantities of cables and accessories supplied with each redundancy kit take such operational limitation into consideration. 3) The type of 1:1 Y-Splitter cable required for modem-to-user interconnection depends on your data interface. It is essential to ensure that the control and IF connections, both Rx and Tx, are made correctly. 4) The Electronic Industries Association (EIA) designations supersede the Recommended Standard (RS) designations. References to the old designations may be shown when depicting actual text (e.g., RS-232) displayed on Switch or the individual modem Web Server pages, serial remote interfaces, Telnet Command Line Interfaces (CLIs), or unit rear panels. All other references in the manual refer to EIA designations. 5) The modem-specific sections in this chapter identify the required redundancy kit: • Section 5.2 Common CRS-170A 1:1 Redundancy Control / IF Interface Cabling Kits • Section 5.3 Cabling the CDM-625A or CDM-625 • Section 5.4 Cabling the Heights Remote Gateway • Section 5.5 Cabling the Advanced VSAT CDM-850 • Section 5.6 Cabling the Advanced VSAT CDM-840

MN/CRS170A.IOM Cables and Connections Revision 14 5–15 5.3.2.2 Modem-to-User IP (10/100 Ethernet) Interface Examples 5.3.2.2.1 Data Interface Connections Using IP Sub-Mux • Appendix N. IP SUB-MUX in CDM-625A Advanced Satellite Modem Installation and Operation Manual (CEFD P/N MN-CDM625A) • Chapter 15. IP SUB-MUX in CDM-625 Advanced Satellite Modem Installation and Operation Manual (CEFD P/N MN-CDM625) Subsystem Multiplex – referred to by CEFD as Sub-Mux – is a secondary framing structure that combines one to four ports of IP (10/100 Ethernet) traffic (see ) with any currently available combination of framing and interface type (see Figure 5-5 through Figure 5-12) – excluding IP itself. The composite data rate to the modulator and from the demodulator is referenced to the primary, non-IP data interface rate by a specific user-selected ratio. 5.3.2.2.2 Managed Switch Mode (with/without the Optional IP Packet Processor) shows the block diagram for the CDM-625A or CDM-625 1:1 modem configuration using the IP (10/100 Ethernet) Interface in Managed Switch Mode (also called Ethernet Bridge Mode). Figure 5-14 shows the cabling example for this setup. This configuration requires no cabling kit – you must use user-provided Ethernet cables and Layer 2 switches for direct connection to the modem via one to four RJ-45 ports. This cabling example shows use of all four Ethernet ports. 1) When in Managed Switch Mode with the Packet Processor either not installed or installed but disabled, all Ethernet ports on the Offline modem will be disabled. The exception is if one of the ports has been set to be the Dedicated Management Port. See the CDM-625A or CDM-625 Advanced Satellite Modem Installation and Operation Manual (CEFD P/N MN-CDM625A or MN-CDM625) for instructions on configuring one of the four 10/100 Ethernet ports as the Dedicated Management Port for remote Ethernet M&C (Dedicated Management Port is available only without the optional IP Packet Processor). 2) When in Managed Switch Mode with the optional IP Packet Processor installed and enabled, only Port 1 of the Offline modem is enabled, while Ports 2, 3, and 4 on the Offline modem are disabled. 3) TO AVOID ETHERNET NETWORKING LOOPS – When in Managed Switch Mode and using more than one Ethernet port, the ports must not be connected to the same Layer 2 Switch unless they are isolated from one another. The ports can be isolated by connecting each port to a separate Layer 2 Switch (see ), or by configuring separate VLAN’s for each port on a single Layer 2 Switch.

MN/CRS170A.IOM Cables and Connections Revision 14 5–18 5.3.2.2.3 Router Mode (Requires Optional IP Packet Processor) • When the optional IP Packet Processor is installed and enabled, you should use Port 1 of each modem for M&C purposes only. Reserve use of Port 2, 3, or 4 for each modem for Ethernet traffic only. • TO AVOID ETHERNET NETWORKING LOOPS – Make sure to connect Port 1 (M&C) and the designated Traffic Port to separate Layer 2 Switches, unless your Layer 2 Switch is configured to isolate these ports by using VLANs. Figure 5-15 shows the block diagram for a CDM-625A or CDM-625 1:1 modem configuration using the IP (10/100 Ethernet) Interface in Router Mode, with the optional IP Packet Processor installed and enabled. The Figure 5-16 cabling example shows Ethernet Port 2 as the designated Ethernet traffic connection. This configuration requires no cabling kit – you must use user-provided Ethernet cables and Layer 2 switch(es) for direct connection to the modem. Figure 5-15.

MN/CRS170A.IOM Cables and Connections Revision 14 5–20 5.3.2.3 PMSI Interface Example The Pre-Mapped Symbol Interface (PMSI) is an EIA-485 point-to-point bus system where one device transmits, and the other device on the bus is configured to receive. It is a function associated with DoubleTalk® Carrier-in-Carrier® (CnC®) that permits the modulator in a selected unit to provide a direct copy of its output (the outbound interferer) to the Offline modem in a 1:1 pair. The Offline modem then takes the PMSI signal and uses it for its own CnC® reference. You must take specific configuration steps to enable CnC® in your CDM-625A or CDM-625 1:1 pair before you can make any switch configurations, This ensures proper operation of the pair within a configured CRS-170A 1:1 Redundancy System. Chapter 4. MODEM AND SWITCH CONFIGURATION Use of PMSI requires that you connect and secure the CDM-625A or CDM-625 Multi-drop CnC® Plus 1:1 Cable CA-0000276 (2X DB-9M, 1’) between the Redundant Modem and the Traffic Modem using CnC.
