Chapter 1 Install the Shelf and Common Control Cards
NTP- G26 Install the TL1 Craft Interface Wires (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 (LAN-POL-REV) 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 Wires (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.
Wrap the ground wire of your computer cable to pin A3 on the craft pin field.

assignments for the CRAFT pin field.
Note
You cannot use the craft backplane pins and the EIA/TIA-232 port on the TCC2/TCC2P card
simultaneously. Using a combination prevents access to the node or causes a loss in connectivity.

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.
