Remote Management (DIP Switch S1, Position 10)
This switch enables or disables the Remote Management mode. Enabling Remote
Management on the Remote module allows all SNMP configurable features for the
Remote modules to be configured from the Host module. By default this feature is
Disabled, and the module acts as a HOST device in this default setting. This feature
can be selected only by setting the DIP Switches manually.
Loopback Testing
The iMcV-DS3/E3/STS-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.
Loopback testing is useful for troubleshooting problems with network connections
should they occur. Looping received data back onto the transmit path helps
determine whether a connection is still valid. Remote loopback tests isolate problems
on the coax run between an iMcV-DS3/E3/STS-LineTerm module and the connected
