Modems
There are several ways to use modems with your system, as described below.
NOTE:
Modems can connect directly to an extension jack without an adapter.
However, if you connect a high-speed modem through the control unit, you may
experience some degradation of efficiency and throughput, depending on the
quality of the outside lines connected to the system. To solve the problem,
either connect modems directly to the network interface jacks, or contact your
local telephone company for information about upgrading line quality.
Stand-Alone Modem for Placing Calls Only
A modem and a terminal allow you to dial out and connect to computer bulletin
boards and other data services. This setup, which lets you dial out but not
receive calls, is shown in Figure 4-7. Note that the telephone is optional and
can be used if you want the terminal to share an extension with a phone.
