• RM 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.
• RAI 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.
Loopback Testing
The iMcV-DS3/E3-LineTerm includes two loopback test modes: Coax Loopback and
Fiber Loopback.
The following illustrations show the path that a signal takes in each of the loopback
test modes.
Each loopback performs the following:
•
Copies the incoming signal back out to the origin while continuing to
transmit this signal downstream.
•
Blocks downstream data from arriving on the looped data line.
