Installing the Multi-Mount Rack

Connections to the port on the DEFINITY ECS and to the analog
line are made through a 50-pin Amphenol connector, which the
customer must supply. This connector provides the connections for
all 12 Rack-Mount Modules (listed as Cards A–L). See the
DEFINITY® Communications System Generic 3, Installation for
Single-Carrier Cabinets manual, document #555-230-894,
comcode #107595423, for complete installation requirements.
Table 3-2 shows the 50-pin connector pinout.
NOTE:
The pin connections for the 50-pin connector are not polarity-
sensitive. Therefore, if you reverse the tip and ring pair, service is
not affected.
