DSU Status Indicators
LED Label
Color Description
OK Green Health and status indicator: DSU operation is normal. The OK LED flashes two times per second
when a message from an NMS is present. When lit, the DSU has not detected any alarm listed
under Alrm, below.
Alrm Red Health and status indicator: There is an alarm in the local or remote DSU, DBM, or DDS facility, or
there is a corrupted configuration. For a DSU with TDM or MCMP, the alarm may be in the
communications path between the DSU and TDM or MCMP circuit card.
Alarms at the local or remote DSU cause the Alrm status indicator to light on the affected DSU.
Refer to Table E-5, Device Health and Status Messages, for further details. DBM health and
status messages are in Document No. 3610-A2-GB49.
Test Yellow When the active core is being tested, the active DSU or DBM device is either performing a test or
other DSUs or DBMs are in Test mode.
The DSU or DBM is automatically put into Test mode
when a remote DSU or DBM is performing a test disruptively. A DSU or DBM in Test mode has
the DTE interface turned Off.
DSU with TDM or MCMP: Any test involving the TDM or MCMP also involves the DSU. The test
is integrated into the DSU’s Health and Status report. When the active core is being tested, any
port included in the active core is also tested.
Dial Yellow DBM is active:
Rapid flashing: Call establish in progress
Slow flashing: Call established but in Standby mode
