DOC ID: 10105711 OSD732 OPERATOR MANUAL Page 11 of 16 2.3 OSD732 OPERATION 2.3.1 OSD732 TELEPHONE CALL OPERATION This section applies to both the OSD732T and OSD732R. When a handset is connected to the OSD732T and an exchange or PABX line is connected to the OSD732R, a conventional telephone circuit is established. If the handset connected to the OSD732T is in the "OFF HOOK" state, the trunk line at the OSD732R end is switched into its active state, thus informing the exchange that the handset is “OFF HOOK”. The exchange feeds a dial tone via the fiber modems to the handset so that the user can then dial the required number. Either tone or decadic loop disconnect signalling can be used. The exchange network or PABX connects the two handsets once the distant handset is picked up and breaks down the connection when either party hangs up following standard telecommunications practice. An incoming call to the handset is first detected by the OSD732R as a ringing signal. The frequency and cadence of this signal is transferred to the OSD732T which generates a similar ring signal and feeds this to the handset. The OSD732T detects when the user picks up the handset and transfers this information to the remote OSD732R which sets the attached trunk line to the active state. This causes the initiating exchange or PABX to stop the ring signal and a two-way conversation can then start. Figure 5 below illustrates the RJ11 connection FIGURE 5: RJ11 PINOUT CONFIGURATION 1 2 3 4 5 6 1 – N/C 2 – N/C 3 – TIP 4 – RING 5 – N/C 6 – N/C

DOC ID: 10105711 OSD732 OPERATOR MANUAL Page 12 of 16 2.3.2 TELEPHONE TO TELEPHONE INTERCOM OPERATION* Figure 6 indicates how to connect the OSD732 as Telephone to Telephone Intercom connection. Intercom mode is activated automatically when two OSD732T's are connected back-to-back. Intercom mode operates as follows: 1. Handset A or B goes off-hook, a ringtone should start on handset B or A respectively. 2. Handset B or A goes off-hook, the ringtone should stop and audio communication between handset A and B is possible. 3. Handset A and/or B go back on-hook, the communication is stopped and the system resets. Note: For 4 channel OSD732 versions, the handsets will communicate through the corresponding channels (ie Ch1 to Ch1, Ch2 to Ch2, etc) FIGURE 6: TELEPHONE TO TELEPHONE INTERCOM 2.3.3 TIP & RING POLARITY REVERSAL* The standard method to transport voice between two telephone sets is to use tip and ring lines. Tip and ring lines are the twisted pair of wires that connect to your phone by way of an RJ−11 connector (see Figure 5 for pin configuration). The tip and ring lines are also used for polarity reversal which is used in a number of examples; 1. A ringing tone is a 20-25Hz toggled signal which produces the ring tone 2. Some countries require Caller Line ID signalling where polarity reversal precedes the transmission of data before the ringing signal. 3. Some systems require reversal of polarity to indicate far end answer eg coin operated phones. In the case where Tip and Ring reversal is encountered at one end (eg OSD732R), the distant OSD732 (eg OSD732T) will transfer the polarity reversal over the fiber link providing system integrity. *Note: This feature is only available on units with serial numbers 10004506 and higher.

When using the OSD732T for the first time, check that the unit is in good condition with no visible damage. If a card version is used, insert it in an appropriate slot on the OSD chassis and check that the indicators illuminate accordingly on power up. If a module version is used, connect the unit to an appropriate power source and check that the indicators illuminate accordingly on power up. In either case take special note of the “Laser OK” indicator, it should be "Off". If it is red there may be a problem with the laser. Disconnect power and have the Laser checked as soon as possible. Finally, plug in the optical connectors of the optical cable. If the remote OSD732R is connected, the "Receive OK" LED will change from Red to Green. Ensure that the correct signals are connected to the correct pins of the RJ11 connector as specified in Figure 5.

When using an OSD732R for the first time check that the unit is in good condition with no visible damage. If a card version (OSD732R) is used, insert it in an appropriate slot on the OSD chassis and check that the indicators illuminate accordingly. If a module version (OSD732RC) is used, connect the unit to an appropriate power source and check that the indicators illuminate accordingly. The “Laser OK” indicator LED should be "Off" in both Card and Case Versions, if the LED is red there may be a problem with the laser. Disconnect power and have the Laser checked as soon as possible. Connect the optical cable: if adequate optical power is received and signal is locked the “Receive OK" indicator will change from ‘red’ to ‘green’.
