Chapter 3. Operation

REMOTE LOOPBCK

This activates the same loopbacks as Local Loopback but at the far end. It uses either the inband loop-up code as specified by ANSI T1.403 for line loopback (ATT In-Band LLB), or the FDL as specified in ANSI T1.403 for payload and line loopback codes. The following options are available:

ATT In-Band LLB Activates the line loopback using inband code

ANSI FDL PLB Initiates the transmission of an FDL payload loop-up code toward the far end

ANSI FDL LLB Initiates the transmission of an FDL line loop-up code toward the far end

No Loopback Deactivates the loopback

Remote Loopback cannot be used with Fractional T1 since the full T1 stream including the FDL is not transported to the far end.

After a Remote Loopback option is selected, the TSU 600 verifies that the far end is actually in a loopback by checking for the receipt of a code looped back from the far end. Once the Remote Loopback type is selected, the LCD displays the loopback progress by displaying Looping until loopback is verified.
