Paradyne COMSPHERE 3611 - Manual (Page 18)

Front Panel Operation

Status Indicators
The status indicators on the Model 3610 DSU’s front
panel and on the Model 3611 DSU’s faceplate
continuously provide information on the current operating
condition of the DSU.
Refer to the COMSPHERE 3000 Series Carrier
Installation Manual for SDCP status indicator tables;
these are unchanged by the presence of a TDM or MCMP
circuit card.
The status indicators of the carrier-mounted
Model 3611 DSU are spread across the SDCP, DSU,
TDM, or MCMP faceplates. Refer to Table 3-1 for
TDM
and MCMP status indicators and descriptions.
Table 3-1
Model 3611 TDM and MCMP Status Indicators
LED Color Description
OK Green Health and status indicator: TDM or
MCMP operation is normal. Indicator
flashes two times per second if a
message is present.
Alrm Red Health and status indicator: There is
an alarm in the TDM or MCMP
hardware, firmware, or a corrupted
configuration.
A voltage spike on the power line or
momentary loss of power may cause
an alarm. The DSU automatically
reloads the TDM or MCMP
configuration options. When the reload
has completed, the Alrm LED goes
Off and the TDM or MCMP OK LED
comes ON.
Port 1,
2, 3, 4,
5, or 6 Green TDM or MCMP mode: Shows ports
currently being monitored. The status
of the port’s leads is displayed on the
faceplate of the associated DSU.
One of the six ports can be monitored
at any given time; the port to be
monitored is selected at the SDCP.
When Network Interface is set to
aggregate switch (AggSw), all ports
are monitored and all LEDs will be
ON.
Bridge mode: The port LEDs perform
differently. The LEDs indicate which
ports had RTS ON during the last
second.
When the port is connected to a DCE
device, the port RTS becomes the
received LSD signal of the DCE
device. The LEDs indicate which ports
had upstream activity during the last
second.
