System installation includes programming features, settings, and options selected by you or a representative from your company.

Depending on the feature, either you, as system manager, or a person at his or her extension can make changes to features:

■System Programming. Used to program systemwide or group features. A Lucent Technologies technician can also do system programming. You use one of the following:

—An MLX-20L telephone, referred to as the programming console

—A PC with System Programming and Maintenance (SPM) software, reaching the system in one of three ways: a direct connection between the PC and the system’s control unit, an on-site or local modem connection to the modem in the control unit, or an off-site remote modem connection.

■Extension Programming. Can be performed in two ways:

—Centralized Telephone Programming. You program at the programming console.

—Telephone Programming. Either you or the user programs at a specific telephone.

When programming at an MLX telephone or PC, you work with features and options from screen menus. You simply select an item from the menu and enter settings as desired.

System Capacities 2

The system can support up to 80 line/trunk jacks, 72 of which can actually be B-channels supplied on 100D modules or 800 NI-BRI modules (Release 4.0 and later systems).

The maximum number of extensions depends on the type of equipment included in the system. In theory, you can connect as many as 255 extensions, but this, in fact, is not practical. In Release 4.0 and later systems, a higher-capacity tip/ring (T/R) extension module, the 016, allows the system to support as many as 200 T/R devices such as single-line telephones, modems, and fax machines. The number of extensions you can connect depends on the equipment you are using in your system.

Appendix C describes hardware and software capacities, that is, the minimums and maximums for certain features.

If you have any questions about your system’s capacity, contact your Lucent

Technologies representative.
