Making E1 or Analog Synchronization Output Connections

Connect the E1 or analog synchronization outputs at the wire-wrap pins or BNC
connectors labeled El OUT A and El OUT B. If using the wire-wrap pins, connect the
tip wire to the pins labeled T, the ring wire to the pins labeled R, and the shield to
the pins labeled S. See
Figure 3-10
Notes:
1. For wire-wrap connections, the shield pin is provided to ground
2. A BNC connector can be used for one output, and a wire-wrap
Warning: To avoid possible equipment damage, do not connect the
El output line directly to a point outside the building. The El output
circuits do not provide lightning protection.

Making 1 PPS Output Connections

Connect an RG-58 coaxial cable from the connector labeled TTL PPS to the
equipment that will use the 1 pulse-per-second TTL output signal. See
for the connector location.

the cable shield at the shelf, if required. Normally, the shield is
grounded at the source. Grounding the shield at both ends is not
recommended.
connector can be used for the other output, but do not use the
BNC and wire-wrap connectors of the same output
simultaneously. For example, a BNC connector can be used for
output A and the wire-wrap pins for output B, but do not use the
output A BNC connector with the output A wire-wrap connector
