DS1 Network Loopup

DS1 Network Loopup

Sends an out-of-band(FDL) loopup or loopdown code over the drop DS1. The Network Interface Unit (NIU), such as a “Smart Jack,” should loop the received DS1 payload back to the DS1 transmit output. See Figure 15-8.

Note: This command works with ESF framing and T1.403 FDL.

Syntax: send ds1 <n> network <loopuploopdown>
