NT8D15 E&M Trunk Card
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 NT8D15 E&M Trunk Card serves various transmission requirements.
The four units on the card can operate in A-Law or Mu-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 27.
The trunk type is selected by making service change entries in the Route Data
Block Program LD 16. The companding mode is selected by making service
change entries in the Trunk Data Block Program (LD 14). Refer to Table 27
to select the proper values for the trunk type being employed. Refer to the
Succession Communication Server for Enterprise 1000 X21 Software Input/
Output Guide (553-3023-311) for LD 14 and LD 16 service change
instructions.
