Modem Installation

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):

Plug the DIN end of the 8-Pin DIN to Mod-8 Cable (P/N 80893) into the CPU serial port.

Plug one end of the DB25 to Mod-8 Adaptor (P/N 85981) into the cable.

Plug the other end of the adaptor into the DB25F connector on the back of your modem.

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:

Using commercially available communications software, dial the phone number of the trunk connected

to the modem at the telephone system site.

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.
