CHAPTER 5
Communication Functions
This chapter explains how to use the built-in modem and the LAN unit.
When you use communications software:
Connect your computer to the AC power source.
Disable power management. (Refer to Disabling Power
Management section of Chapter 3.)
See also the manual or online help of the software you are using.
The communication speed may vary depending on the traffic, local
telecommunications infrastructure, and ISP (Internet Service Provider)
infrastructure.
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.
Within the communications software you are using, set the COM port
of the built-in modem to COM 3 if required.
Before commencing with fax communication, it is recommended that
you exit other application programs.
