DLP-A23 Install DS-1 Cables Using Electrical Interface Adapters (Balun)
Note
All DS-1 cables connected to the ONS 15454 DS-1 ports must terminate with twisted-pair cables to
connect to the DS-1 electrical interface adapter. The DS-1 electrical interface adapters project
1.72 inches (43.7 mm) beyond the SMB EIA. Refer to the “Shelf and Backplane Hardware” chapter in
the
Cisco ONS 15454 Reference Manual
for more information.
Step 1
Attach the SMB connector on an adapter to the SMB connector for the port’s transmit pair on the
backplane.
Step 2
Attach the SMB connector on an adapter to the SMB connector for the port’s receive pair on the
backplane.
Step 3
Terminate the DS-1 transmit and receive cables for the port to the wire-wrap posts on the adapter:
a.
Using a wire-wrap tool, connect the receive cables to the receive adapter pins on the backplane
connector for the desired port.
b.
Connect the transmit cables to the transmit adapter pins on the backplane connector for the desired
port.
c.
Terminate the shield ground wire on the DS-1 cable to ground according to local site practice.
Note
If you put DS1N-14 cards in Slots 3 and 15 to form 1:N protection groups, do not wire Slots 3
and 15 for DS-1 electrical interface adapters.
shows a ONS 15454 backplane with an SMB EIA. DS-1 electrical interface adapters are
attached on both sides of the shelf assembly to create DS-1 twisted-pair termination points.
Purpose
This task installs the DS-1 cables on an SMB EIA using the electrical
interface adapters.
