E1 RJ-48 Connectors
ALARM:
• OFF during normal operation
• Blinks red+green simultaneously
when CV errors detected on the E1
line at far end of the optical line
• Glows red+green when loss of
service (LOS) is detected, OR
continuous bit errors are detected
on the E1 line at far end of the
optical line
• Blinks red when local CV errors
detected on E1 line.
• Glows red when LOS detected on
the local E1 line, OR
when continuous errors are
detected on the local E1 line
STAT:
• Glows green
during normal
operation
• Glows
red+green when
out-of-service or
when the port is
in a loopback or
test state
• Glows red when
the Host to
Remote fiber
link(s) is down or
badly corrupted
SFP Ports
One model offers two SFP (A and B) ports for 1+1 protection; a
second model offers one SFP without protection.
ACT:
• Glows green when the SFP port is the active receive line.
• OFF when the SFP is not the receive line
• Glows red+green when the SFP port is manually forced to
be the active receive line
LNK:
• Glows green when there is a valid link
• Glows red when a loss of optical signal occur, LOF, or with
continuous optical bit errors
RAI:
• Off when no remote defects are detected
• Glows red+green when remote LOS or BER detected
MSA:
• Off when SFP is not an IMC Networks SFP
• Glows green when no SFP alarms are detected
• Glows red+green when SFP alarms or defects are detected
at remote end
• Glows red when SFP alarms or misconfigurations are
detected locally, i.e., when the SFP is missing, or when SFP
speed is not at 155Mbps
