Configuration

Each of the four trunk circuits on the E&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 151 on page 647.

Jumper settings

The NT8D15 E&M Trunk card serves various transmission requirements. The four units on the card can operate in A-Law or µ-Law companding modes, which are selected by service change entries. Each unit can be independently configured for 2-wire E&M, 4-wire E&M, and paging trunk types. The trunk type is selected by service change entries and jumper strap settings.

See Table 203 on page 648.
