High Speed Data Ports 9-7
Figure 9-3. Local DTE Loopback
Choose the net (network) setting to loop the incoming data from the network back toward the
far end. This loopback is shown in Figure 9-4. It tests some of the local HSU Card circuitry,
the local system common cards, the WAN link card, the far-end HSU port and CPE device,
and the WAN link between the two sites. The net setting also drops the Data Set Ready (DSR)
control signal output on the HSU port.
