External timing source input—The 8-pin mini-DIN connector
optionally receives a square wave signal from an external
timing device. For T1 versions this clock must be at 1.544
Mbit/s, for E1 versions it must be at 2.048 Mbit/s.
T1 CIMs
The DS-1 CIM 29010 and the DS-1 CIM 29011 support dual RJ-48C
network port connectors and dual V.35 or EIA 530/RS-449
equipment connectors, respectively.

Data Ports use mini-D-sub 26-pin connectors. They require
adapter cables to properly interface with native connectors.
See
Table 1-2

E1 CIMs provide the following connectors:
•
Two E1 line ports (either coaxial, DE-9, or RJ-45 connectors)
