Communication Functions

This chapter explains how to use the built-in modem and the LAN unit.

Built-in Modem

You can use the built-in modem for data transfer and fax communication.
The built-in modem on your computer is designed only for regular
analog telephone lines. The modem may be damaged when connected
to a digital ISDN terminal or a digital PBX.
Use TA (terminal adapter) to connect the built-in modem to a digital
telephone line.
If an unusual device is attached to the line you are connecting to, the
modem may not function properly. Remove the device or contact the
dealer of the device.
Before connecting to a PBX, consult the PBX maintenance staff or its
service company. If the electric characteristics of your PBX are
different from those of a regular analog line, the modem will not
function properly. If you connect the modem to a digital PBX, both the
modem and the PBX may be damaged.
Connecting the Modem to a Telephone Line
