LOCAL LOOPBCK

There are three available choices for setting the local loopback:

LINE ON

Activates the line loopback

PAYLOAD ON Activates the payload loopback

NO LOOPBACK Deactivates the loopback

Using the arrow keys, select a setting and record it by pressing Enter. The unit returns the display of 1) LOCAL LOOPBCK and

2)REMOTE LOOPBCK

REMOTE LOOPBK

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