TDM and MCMP Status Indicators (Model 3611 Only)
Label Color Description
OK Green Health and status indicator. The TDM or MCMP hardware and software
are operating normally.
This indicator flashes two times per second if a message is present.
Alrm Red Health and status indicator. An alarm condition in the TDM or MCMP
hardware, firmware, or configuration data is disrupting normal operation
of the TDM or MCMP processor.
Configuration alarms may be caused by a voltage spike on the input
power line or momentary loss of power; the DSU automatically reloads
the TDM or MCMP configuration options. When the reload procedure is
completed, the Alrm LED goes Off and the TDM or MCMP OK LED
comes ON.
Port 1, 2, 3, 4, 5,
or 6 Green In TDM or MCMP mode,

shows which port is being monitored (the
status of the port’s leads is displayed on the faceplate of the associated
DSU).
Any one of the six ports can be monitored at any given time; the port to
be monitored is selected at the DCP (or SDCP). If the aggregate (Aggr)
is monitored, all LEDs will be ON.
In Bridge mode, the port LEDs perform a very different function. Each
second, the LEDs indicate which ports had RTS ON during the last
second. If the port is connected to a DCE device, the port RTS becomes
the received LSD signal of the DCE device. Therefore, the LEDs
indicate which ports had upstream activity during the last second.

Only the MCMP circuit card can be configured for MCMP mode of operation.
