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 Remote
Management is enabled. Glows green on the Host unit
when it has discovered a manageable Remote unit. Under
normal operation this LED is the only LED that is ON.
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.
