2. To activate all the sublink loopbacks and tests, type:
LOOP SL<Enter> or LP SL<Enter>
To activate a specific sublink loopback or test, type:
LOOP LOC ANA SL<Enter> or LP LOC ANA SL<Enter>
LOOP REM ANA SL<Enter> or LP REM ANA SL<Enter>

LOOP LOC CH 1<Enter> or LP LOC CH 1<Enter>
LOOP LOC CH 2<Enter> or LP LOC CH 2<Enter>
LOOP REM CH 1<Enter> or LP REM CH 1<Enter>
LOOP REM CH 2<Enter> or LP REM CH 2<Enter>
• Inband loopback and BER testing are available on channel 1 only.
• The activation of an inband loopback is made by repeatedly transmitting the
activation sequence, therefore the loopback can be considered as activated
only after approximately 2 seconds.
If the requested loopback is already active, you will receive ERROR 053: CURRENT
LOOP ALREADY BEING PERFORMED. If the requested loopback is not supported by
the FCD-E1LC version, you will receive ERROR 055: LOOP NOT SUPPORTED ON
CURRENT FCD TYPE.
If you are trying to activate a loopback on a data channel of an FCD-E1LC with
Ethernet interface, you will see ERROR 056: ILLEGAL COMMAND FOR CURRENT
PORT MODE. Nevertheless, the BERT test (LOOP BERT) is allowed.
