The iMcV-T1/E1/J1 can be configured to use the following loopback test modes:
•
Local Fiber Loopback Mode
This setting tests the path from the CO copper port to the Local iMcV-T1/E1/J1
module fiber port and back.
•
Remote Fiber Loopback Mode
This setting tests the path from the CO copper port to the Remote iMcV-T1/E1/J1
module fiber port and loops it back.
•
Remote Copper Loopback Mode
This setting tests the path from the CO copper port to the Remote iMcV-T1/E1/J1
module copper port and loops it back.
The following illustrations show a typical progression of digital loopback tests; this
series allows you to individually test each segment of the conversion. To test the
copper segment at the remote location requires the PRBS test described in the next
section.
Local Fiber Loopback Mode
To set the loopback testing mode to Local Fiber Loopback Mode, perform the
following:
1.
Set the Local iMcV-T1/E1/J1 module to
Remote
Loopback
(DIP switch S3-3=Off and S3-4=Off)
2.
Set the Remote iMcV-T1/E1/J1 module Loopback to
None
(DIP switch S3-3=On and S3-4=On).
This configuration allows you to test the path from the CO copper port to the Local
iMcV-T1/E1/J1 module fiber port and loop it back. The transmitted data is sent
unhindered and the received data is ignored.
