DS1 Payload Loopup
DS1 Payload Loopup
Sends an out-of-band (FDL) payload loopup or loopdown code over the Access Navigator drop DS1.
The CSU should perform a payload loopback, which loops the received DS1 payload back to the DS1
transmit output (see Figure 15-10).
Note: This command works with ESF framing and T1.403 FDL.
Syntax: send ds1 <n> payload <loopup|loopdown>
