4.6 MAIN CABINET WIRING
With the Enhanced Main Cabinet, telephony connections (PSTN, ISDN, SLT, and DTIM) are made
through male RJ-21X 25-pair connectors mounted on the back plane. Modules terminate the
telephony interfaces at the appropriate connector on the back plane, using connector pairs (circuit
locations) based on the Module location in the cabinet. Each slot is terminated on the appropriate
male RJ-21X connectors. The relationship between slots and RJ-21X connectors is shown in
Figure 4.6-1.
Complete all the telephony wiring for the Module prior to installing and applying power to the
Module. Note also consider the slot and sequence assignments when installing Modules, refer to
section 4.5.1.1.
Complete all telephony wiring by making cross-connects between the RJ-21X and the appropriate
telephone company termination point. For details, see the following figures. Note the red boxes
indicate wiring for the PRIM.
