See Table 281 "Pad switching algorithm" (page 711) for the pad switching
control for the various through connections and the actual port-to-port
loss introduced for connections between the E and M Trunk card and any
other IPE port designated as Port B. Figure 242 "Pad orientation" (page
713) shows the pad switching orientation.

Note: Transmit and receive designations are from and to the CS 1000. Transmit is from the CS
1000 to the external facility (digital-to-analog direction in the E and M Trunk card). Receive is to the
CS 1000 from the external facility (analog-to-digital direction in the E and M Trunk card).

Applications
The optional applications, features and signaling arrangements for each
trunk are assigned through unique route and trunk data blocks. Refer to
Features and Services (NN43001-106-B) for information about assigning
features and services to trunks.
