Installing a Modem
You can connect a modem to the system’s serial port to remotely collect history data and/or SMDR. Be aware
that remotely collecting SMDR may not be advisable since the system can buffer only 50 SMDR call records.
To connect a modem (Figure 5-5):
1. Plug the DIN end of the 8-Pin DIN to Mod-8 Cable (P/N 80893) into the CPU serial port.
2. Plug one end of the DB25 to Mod-8 Adaptor (P/N 85981) into the cable.
3. Plug the other end of the adaptor into the DB25F connector on the back of your modem.
4. Following the instructions that came with your modem, connect a trunk and the modem’s power supply.
To call from a PC at a remote site:
The remote PC must have a modem connected. Also, the default communications parameters of
the CPU serial port are 19200 8 N 1 (19200 baud, eight data bits, no parity and 1 stop bit).
1. Using commercially available communications software, dial the phone number of the trunk connected
to the modem at the telephone system site.
2. To test history, type Shift 1 on the remote PC.
If history doesn’t output correctly, press Ctrl Break on the remote PC to toggle through the
available CPU baud rates.
