Label
Color
Description
OK
Green
Health and status indicator. The DSU’s operation is normal. (The DSU
has not detected any alarm listed in the next section labeled Alrm.)
This indicator flashes two times per second if a message is present.
Alrm
Red
Health and status indicator. An alarm in the local or remote DSU. For the
DSU with TDM or MCMP,
1
the alarm may be in the communications
path between the DSU and TDM or MCMP circuit card.
The following alarms at the local or remote DSU cause the Alrm status
indicator on the affected DSU to light: Configuration Corrupt, Device
Alarm, Dial Tone Test Failure, DTE Alarm, Facility Alarm, MUX Failure,
No Response, Redundant Power Alarm, Streaming Terminal,
Subnetwork Alarm, and Out-of-Frame Threshold.
Test
Yellow
Active device (DSU or DBM) is either performing a test, or other DSUs or
DBMs are in Test mode. For a DSU with TDM or MCMP, test activity may
be in the TDM or MCMP circuit card.
2,3
Dial
Yellow
DBM active:
Rapid flashing: Call setup in progress
Slow flashing: Call established but in Standby mode
Steady ON: Backup call established and active
TXD, RXD, RTS,
CTS, DSR, DTR,
LSD
4
Green
Internal lead states at DSU/DTE interface
(circuit designations):
Control circuit active,
or
Data circuit SPACEing.
For the DSU with TDM or MCMP, the circuit external lead states for any
of the TDM or MCMP ports can be selected from the DCP via the Control
Branch.
For a 3611 Series DSU with TDM or MCMP, the port LED illuminated on
the TDM or MCMP faceplate indicates the monitored port. For
Model 3610 DSUs, the monitored port is displayed on the DCP’s LED
display.
Front Panel
(Model 3611 only)
Yellow
DSU is currently selected by the SDCP (
the SDCP addresses one DSU
at a time).
For Model 3611 DSU with TDM or MCMP, the TDM or MCMP circuit card
is also selected (
the TDM or MCMP circuit card has the same address as
its associated DSU).
1
Health and status for the TDM or MCMP is integrated into the Health and Status report for the DSU. For an
alarm in the DSU with TDM or MCMP, this report indicates whether the TDM/MCMP or DSU is at alarm.
2
Any test involving the TDM or MCMP also involves the DSU, and the test is integrated into the DSU’s
Health and Status report.
3
The DSU or DBM is automatically put into Test mode when a remote DSU or DBM is performing a
disruptive test (e.g., a Local Loopback at the control DSU — select LL). A DSU or DBM in Test mode has
its DTE interface turned Off.
4
When the TDM or MCMP option is installed, DTR will always appear as ON for Port 1. Refer to the DTE
Status display on the DCP to determine the state of the DTR lead.
