Lucent Technologies 4.1 manual Modems, Stand-Alone Modem for Placing Calls Only

Modems

There are several ways to use modems with your system, as described below.

N O T E:

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 4-9. Note that the telephone is optional and can be used if you want the terminal to share an extension with a phone.

To Use

Follow the modem manufacturer’s instructions.

To Program

1.If extension X is a key extension, use Line Assignment (#301) to assign one or more lines to extension X.

If extension X is a pooled extension, use Pool Extension Assignment (#314) to assign the pools you want the modem to use to extension X. Also use Line Assignment (#301) to assign any individual lines you want the modem to

use to extension X.

2.If the modem will only dial outside the system, set Automatic Line Selection for extension X to select outside lines first. If you also use the modem for calls within the system, set Automatic Line Selection to select intercom first, and include a 9 or a pool access code and a couple of pauses in the modem’s dialing sequence for outside calls.

3.Set Line Ringing for all lines and pools assigned to extension X to No Ring.
