9. PORT PACKS: DEFINITY GENERIC 2 WITH UNIVERSAL MODULES

This chapter presents supplementary information on port circuit packs, and loop distances for terminals
that you may find useful in designing a wiring installation.
Digital communications protocol (DCP) guidelines for DEFINITY® Generic 2 Communications System
(hereafter abbreviated to DEFINITY Generic 2 or Generic 2) with universal modules are the same as
those for System 85 and DEFINITY Generic 2 with traditional modules. See chapter 4, Port
Packs/DCP Repeaters: System 85 and DEFINITY Generic 2 with Traditional Modules, for more detailed
information.

PORT CIRCUIT PACKS

Table 9-1, Port Circuit Pack Cabling, identifies the circuit packs that are housed in the universal module
control (UMC) common port carrier (CPC) and the fields on the main distribution frames (MDF) where
cables from those packs terminate. There are 20 circuit packs per carrier, and one 25-pair cable serves
each pack. The table also gives the number of ports for each circuit pack. There are 8 ports for each
digital pack and 8 or 16 ports for each analog pack. Table 9-1 also lists the fields for cable termination.
Table 9-2, Terminals and Peripherals Served by Port Packs, list the voice terminals that each circuit
pack can serve, and table 9-3, Voice Terminals Loop Ranges, list the loop ranges for voice terminals.
The design of the MDF must allow for the termination of all 20 carrier cables even if the carrier is not
slated for a full complement of circuit packs. The design should not allow for vacant carrier positions
unless such an allowance is specifically requested.
