Mass Termination Connector
As an option, a 50-pin mass termination connector may be specified for the TELCO connection.
The adapter for conversion from modular connectors to mass termination also has wire-wrap
pins for TELCO connection.
Mass termination pin functions for the dial backup backplane are shown in the following table.
The 50-pin mass termination connectors are Cinch Number 97-CS-50 with screw lock assembly.
The mating connector is 97-12500-181, or equivalent. Wire wrap pins are not available.
NOTE:
TELCO jack pin functions are identical for both standard and
dial backup modems.
DTE connectors are the same as for standard modems.
