2.18.4 Supporting Caller Identification Service
You can provide Caller ID information through the serial data port COM2 using the Caller ID
Interface (product code CID08) and a special equipment-supplied cable. Caller ID information
for incoming calls shows on the displays of the system’s LCD speakerphones.
Make the connections that are detailed in the following statements.
•
Connect the CO lines providing Caller ID data to both the common equipment and the
CID08 line jacks in the same numerical order.
•
Connect the CID08-supplied cable between the CID08 and the COM2 serial data
connection on the common equipment.
•
With the Caller ID Interface installed, you can also add two leads to provide the TD and SG
signals to a data printer or personal computer (PC). These leads are useful for adding caller
ID enhancement to the SMDA/SMDR printout or for providing messages in the ASCII
format suitable for use with PC-based applications programs.
