2 Control Unit Configuration
Planning Module Placement
each module with respect to type (line/trunk or extension) and its associated
logical ID. Each physical jack on the control unit is numbered sequentially from
bottom to top and left to right with logical IDs as follows:
Extension jacks are numbered from 1 to 200.
Line/trunk jacks are numbered from 1 to 80.
This sequence of logical IDs is the basis for connecting components to the control
unit, as well as for the assignment of extension numbers and line/trunk numbers.
Planning Form Instructions
NOTE: NOTE: NOTE:
The Unit Load blocks above the diagram are reserved for equipment
changes or maintenance. A technician computes these values manually.
1. On the Control Unit Diagram of Form 1 (page 2), record the type of module
to be installed in each slot by writing the module name (for example, 008
MLX) on the slanted lines at the top of each slot. Use the following
guidelines:
Indicate the power supply module in the far left slot of each carrier.
Indicate the processor module in Slot 00 of the basic carrier.
Indicate line/trunk and extension modules in any order in Slots 01
through 17, with the following conditions:
— Group the modules in each carrier from left to right with no
empty slots between modules. (The system does not
recognize modules in slots that follow an empty slot; slots to
the right of the last module can be left empty.)
— (Hybrid/PBX mode only) If the system includes a Queued
Call Console (QCC), the first line/trunk and/or extension
module must be a 408 GS/LS-MLX or 008 MLX module.
— (All modes) Current 012, 008 OPT, and 016 modules have
built-in ring generators and are compatible with earlier
releases. The 012 module [517G13 (28)] has a ring
equivalency number (REN) of 2.2 and rings only 4 ports at a
time, although 8 jacks can be used for applications. The 016
module (517A34) has a REN of >= 4, can ring 16 ports at a
time, and has no restriction on the number of jacks that can
be used for applications.
— Group all 800 DID, 100D, 800 NI-BRI, and 400EM modules
together according to type; this may save time in system
programming.
