Configuration
This section outlines the procedures for configuring the switches and
jumpers on the NT8D09 Analog Message Waiting Line card and configuring
the system software to properly recognize the card.
Figure 138 "Analog
message waiting line card - jumper block and switch locations" (page
561)
shows where the switches and jumper blocks are located on this board.
Jumper and switch settings
The NT8D09 Analog Message Waiting Line card has no user-configurable
jumpers or switches. The card derives its address from its position in the
backplane and reports that information back to the CPU through the LAN
Link interface.
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
Table 226 "Transmission Profile Changes" (page 560) .
