Voice Modules (VCMs & DPVs)
DPV Front Panel
Table 6-4
shows the front panels of all DPV modules and explains the function of each switch and
indicator. You can check the operation of each unit by monitoring the front panel indicators. The
colors of the LED indicators on the modules front panels are consistent in function:
•
Red and yellow are used for alarms or "service-affecting" conditions. This includes test modes
that are interfering with normal user data.
•
Alarm conditions depend on the modules, but normally, red indicates a Major Alarm (a number
of problems), and yellow indicates a Minor Alarm (channel alarms).
•
The green LED indicators are used for all other conditions.
