Remote Loopbk
This activates the same loopbacks as Local Loopback but at the far end.
It uses either the inband loopup 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:
Remote Loopback can only be used with Fractional T1 if the ANSI FT1 LLB is
selected.
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 select-
ed, the LCD displays the loopback progress by displaying
Looping
until
loopback is verified.
