Installation
iMcV-DS3/E3-LineTerm modules can be installed in any iMediaChassis, MediaChassis
or iMediaCenter chassis, but can be managed only through the iMediaChassis.
Remote modules can also be installed in either chassis, but cannot be managed by
the local chassis. Each module requires one slot in the chassis. To install a module,
remove the blank brackets covering the slots where the module is to be installed by
removing the screws on the outside edges of the bracket. Slide the module into the
chassis card guides, until the module is securely seated in the connector. Secure the
module to the chassis by tightening the captive screw. Save any blanks removed
during installation for future use.
It is not recommended that the iMcV-DS3/E3-LineTerm module be installed in an IE-
MediaChassis/1-DC chassis. The power source in this chassis is not isolated and
cannot support positive referenced ground systems typically used in Telco
environments. The IE-MediaChassis/2-DC and the iMediaChassis/6-DC are suitable
alternatives.
LED Operation
The iMcV-DS3/E3-LineTerm module features several diagnostic LEDs per port. The
LED functions are:
LEDs Next to Coax (BNC) Port
• ER Flashes yellow whenever a line code violation is received.
• LOS 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.
• PRBS Glows green when the BNC port receives a valid
Pseudorandom Bit Sequence. Off when the port is not
receiving a Pseudorandom Bit Sequence.
• LPBK Glows yellow when the module is in either coax or fiber
loopback mode.
LEDs Next to Fiber Optic Port
• ER Glows yellow when a fiber symbol error has been received.
• LOS 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.
