Warning
Metallic interfaces for connection to outside plant lines (such as T1/E1/T3/E3, etc.) must be
connected through a registered or approved device such as CSU/DSU or NT1.
Step 5 Label the transmit, receive, working, and protect cables at each end of the connection to avoid confusion
with cables that are similar in appearance.
1.11 DS-1 Cable Installation
DS-1s support both twisted pair wire-wrap cabling and AMP Champ connector cabling. Install the
proper backplane EIA on the ONS 15454 for each cabling option. This section provides information
about the DS-1 EIA options.
For information about DS-1 cable management, see the “DS-1 Twisted-Pair Cable Management” section
on page 1-58.
1.11.1 Twisted Pair Wire-Wrap Installation
Installing twisted-pair, wire-wrap DS-1 cables requires separate pairs of grounded twisted-pair cables
for receive (in) and transmit (out). Prepare four cables, two for receive and two for transmit, for each
DS-1 facility to be installed.
