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:

Name	Description

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

ANSI FDL PLB	Initiates the transmission of an FDL payload
	loopup code toward the far end

ANSI FDL LLB	Initiates the transmission of an FDL line
	loopup code toward the far end

ANSI FT1 LLB	Initiates the transmission of a FT1 loopback
	using the inband code described in T1.403.

No Loopback	Deactivates the loopback

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.
