NT8D09 Analog Message Waiting Line card

Software service changes

Individual line interface units on the NT8D09 Analog Message Waiting Line card are configured
using the Analog (500/2500-type) Telephone Administration program LD 10.
The message waiting feature is enabled by entering data into the customer data block using
LD 15. See Software Input/Output Reference — Administration (NN43001-611) for LD 10 and
LD 15 service change instructions.
Analog message waiting line cards with a vintage later than NT8D09AK provide a fixed +2 dB
transmission profile change in the gain of the D/A convertor. See
Profile Changes
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.
