Installing and cross-connecting a trunk card
Note: The speech pairs on the NT5K19 card are polarity-insensitive.
The E&M signaling pairs, however, are polarity-sensitive. Make sure the
ground side of the trunk is connected to the A leg of the NT5K19 circuit.
Make sure the -50 Volt side of the trunk is connected to the B leg.
