LED Operation
The iMcV-DS3/E3/STS-LineTerm module features several diagnostic LEDs per port.
The LED functions are:
ER
LOS
PRBS
LPBK
ER
LOS
RM
RAI
LEDs Next to Coax (BNC) Port
Flashes yellow whenever a line code violation is
received.
Glows red when the BNC is receiving no signal and is in
an LOS ALARM state, resulting in sending an RAI signal
to the fiber port. If Fault Loopback is set to ON, then
AIS will also be sent to the Coax line as well.
Glows green when the BNC port receives a valid
Pseudorandom Bit Sequence. Off when the port is not
receiving a Pseudorandom Bit Sequence.
Glows yellow when the module is in either coax or fiber
loopback mode.
LEDs Next to Fiber Optic Port
Glows yellow when a fiber symbol error has been
received.
Glows red when a link is not established and is in a LOS
ALARM state and will send an AIS signal to the BNC
Line. If Fault Loopback is enabled, then an RAI Signal is
also sent to the fiber line.
Glows green on the Remote Unit when set to DSW S1-
10. Glows green on the Local unit when it has
discovered a Remote management with Remote Unit
enabled.
Glows
yellow when a Remote Alarm Indication is
received on the fiber port. When the fiber port receives
an RAI signal, this will force AIS to transmit on the COAX
Line.
Features
The iMcV-DS3/E3/STS-LineTerm module includes several features that allow it to be
configured for DS3, E3/STS, or STS-based environments.
