Lucent Technologies 4.1 Manuale Utente

If you are upgrading from a PARTNER or PARTNER Plus system, you can still
use its 200E modules, each providing two line jacks.

If you want message waiting capability on standard phones that are equipped
with message waiting lights, you must connect those phones to extension jacks
on Release 3.1 (R3.1) or later 206 modules. Additionally, you need an R3.1 or
later primary processor module.

The combination of 206 and 400 modules installed determines the number of
available lines and extensions. The system allows up to 24 lines and up to 48
extensions; however, these maximums cannot be achieved simultaneously:

For maximum line capacity (24 lines), install four 206 modules and four
400 modules. This arrangement allows up to 24 extensions.

For maximum extension capacity (48 extensions), install eight 206
modules. This arrangement allows up to 16 lines.

The system supports two modes of operation. The mode of operation

determines how users access outside lines from their phones:

Key Mode. Users access individual outside lines to make and receive
calls.

Hybrid Mode. Users can access individual outside lines as in Key mode.
However, you also can create up to four groups, or pools, of multiple
outside lines. When the user accesses a pool to make a call, the system
selects an available line from the pool. Since multiple lines are
associated with the pool, the user does not know which line within the
pool is being used to make the call.

System mode is determined by the configuration of the processor module. By
default, the system is configured for Key mode. Changing to Hybrid mode
requires modifying the processor module.  Only Lucent Technologies

The mode for your system must be decided upon before installation; and in the

continental U.S., the mode must be registered with the Federal Communications
Commission (FCC) (see “FCC Registration” later in this section).
