A frame ground pin is located beneath each pin field (FG2 for the LAN pin field). Wrap the ground shield of
the LAN interface cable to the frame ground pin. Table 13: LAN Pin Assignments, on page 99 shows the
LAN pin assignments.

The ONS 15454 ANSI is a DCE.
The TCC2/TCC2P/TCC3 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.

DLP-G26 Install the TL1 Craft Interface Wires (ANSI Only)
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/TCC3 EIA/TIA-232 port to access a TL1 craft interface.
