• transmission line performance monitoring and Fault Management with
Alarm reporting
• downloadable PAD value for Loss level control and A-law/Mu-law
conversion
• Elastic Buffer for Slip Control
• alarm detection and generation
• Uniform Delay on all time slots in Nx64 formats
The NTMW04 has eight faceplate LEDs. The first six LEDs are associated
with the NTMW04 card itself, and the remaining two LEDs are associated
with the clock controller and DCHI daughterboards.
In general, the first six LEDs operate as follows:
• During system power up, the LEDs are on.
• When the self-test is in progress, the LEDs flash on and off three times,
then go into their appropriate states, as shown in
September 1998
