16-PORT ANALOG LINE BOARD ADAPTER CABLE
The 16-port analog line circuit pack (TN746) has an output of sixteen 1-pair circuits that
appear on a 25-pair connector at the switch. The 16-port analog line adapater cable
(Figure 3-14) separates the 1-pair circuits into 3-pair circuits that appear on two 25-pair
connectors at one end of the cable.
The adapter cable is 8 feet (2.4 m) long and can be ordered with the TN746 circuit pack. The
adapter cable is apparatus-coded as an adapter and can also be ordered below. This cable
should only be used with 110P-type hardware. Punch-down cross-connections using 110A-
type hardware allows direct access of the 16 ports via a single 25-pair cable. See Table 3-K
for lead assignments.
