LSD-5 Line Preselector Module
All user wiring to and from LSD-5 modules takes place at AMP 12-
pin connectors mounted directly beneath module on the console
mainframe’s bottom pan. There are four connectors per module (AMP A
and B for control, AMP C and D for power) that wire to two DB-25s on
the LSR-500 chassis rear.
