2=Test 1=Loopback DTE 2=Loopback Proto 3=2047 Checker 4=NEBE/FEBE 5=Software Ver

Loopback DTE

Causes both DTE ports to loopback toward user equipment. This allows per- formance of a bit error rate test (BERT) between the ISU 512 and end user equipment to verify proper cable connection, etc.

Loopback Protocol

Allows data to be looped back toward the network after passing through BONDING protocol. See Figure 6-1 for loopback points.
