Cabling
The DS-3 or DS-3/STS-1 I/O rear interface modules provide the
terminations for three or eight DS-3 or STS-1 ports. Each module
terminates DS-3 or STS-1 ports with an input and output BNC connector
for each DS-3. The rear DS-3 (triple) IOM connectors are shown in
and the Octal DS3/STS-1 IOM connectors are shown in
The DS-3 cables typically terminate at a DSX-3 cross-connect and the
cable distance to the DSX-3 cross-connect panel cannot be greater than
450 feet. Refer to
for an illustration of the triple DS-3 cable
for the octal. DS-3 cabling in a rack is shown in
