Analog message waiting line card - typical cross connection example
This transmission profile change is used for control of end-to-end connection
loss. Control of such loss is a major element in controlling transmission
parameters such as received volume, echo, noise, and crosstalk. The loss
plan for the analog message waiting line card determines port-to-port loss
between an analog line card unit (port) and other IPE ports. LD 97 is used
to configure the system for port-to-port loss. See Software Input/Output
Reference — Administration (NN43001-611) for LD 97 service change
instructions.
