Cisco ONS 15454 DWDM Installation and Operations Guide, R6.0
August 2005
Chapter 1 Install the Shelf and Common Control Cards
DLP-G26 Install the TL1 Craft Interface (ANSI Only)
Note
The TCC2/TCC2P does not support Ethernet polarity detection. If your Ethernet connection has
incorrect polarity (this can only occur with cables that have the receive wire pairs flipped), a
“Lan Connection Polarity Reversed” condition is raised. This condition usually occurs during an
upgrade or initial node deployment. To correct the situation, ensure that your Ethernet cable has
the correct mapping of the wire-wrap pins.
Step 2
Return to your originating procedure (NTP).
DLP-G26 Install the TL1 Craft Interface (ANSI Only)
Note
Rather than using the craft pins, you can use a LAN cable connected to the TCC2/TCC2P EIA/TIA-232
port to access a TL1 craft interface.
Step 1
Using #22 or #24 AWG (0.51 mm² or 0.64 mm²) wire, wrap the craft interface wires on the appropriate
wire-wrap pins according to local site practice.
Step 2
Wrap the ground shield of the craft interface cable to the frame-ground pin.

Purpose
This task installs the TL1 craft interface on the ONS 15454 ANSI shelf
using the craft backplane pins. You can also use a LAN cable connected to
the TCC2/TCC2P EIA/TIA-232 port to access a TL1 craft interface.
