• 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.
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.

NOTE: 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)
• Two data port connections of various protocols (all 26-pin
mini-DIN connectors)
Figure 1-4 shows all the E1 CIM configurations.
