TCC2/TCC2P card to access a TL1 craft interface.
Using #22 or #24 AWG (0.51 mm² or 0.64 mm²) wire, wrap the craft interface wires on the appropriate

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

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.
