NT5K19 Analog TIE line trunk card terminations
Cross connect the NT5K19 analog TIE line trunk card as shown in Table 67
"NT5K19 2W paging mode terminations" (page 363) .
Note: The speech pairs on the NT5K19 card are polarity insensitive.
The E&M signalling 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 V side of the trunk is connected to the B leg.
