Modems
There are two ways to use modems with your premises equipment, as
described below. Modems can connect directly to an extension jack without an
adapter.
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 7-4. Note that the 267F2 bridging adapter and
telephone are optional and can be used if you want the terminal to share an
extension with a phone.
To use the modem, follow the modem manufacturer’s instructions.
