Field/Command

Description

Equipment Loopback (ELB)—Activates or deactivates an equipment loopback. An

ELB is at the V.35 or HSSI interface facing the local DTE in order to test the

equipment cable and router signal.

Payload Loopback (PLB)—Activates or deactivates a PLB. A payload loopback loops

the signal intended for the near end DTE back toward the far end DTE at the V.35 or

HSSI port. It tests the T1 channels and the IMUX module up to the data port.

AIS Pattern—Selects the desired AIS (Alarm Indication Signal) pattern. Valid options

are: disabled, all ones, or all zeros. Generally “all ones” is the preferred AIS.
