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
—(All modes) Current 012 T/R, 008 OPT, and 016 T/R modules have
a time, although eight jacks can be used for applications. The 016 T/R module (517C34) 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
