Configuration
Each of the four trunk circuits on the E and M Trunk card can be
individually configured for trunk type, companding mode, and port-to-port
loss compensation. Configuring the card requires both jumper changes
and configuration software service entries.
The locations of the jumpers are shown in Figure 239 "E and M Trunk card
- jumper locations" (page 704) .
