Set DS1 Payload Loopup
Purpose:
Provides payload loopback to verify DS1 signal processing in the Quad T1 Framer
card. The payload loopup command creates a signal connection inside the framer,
causing it to loop the received payload data back into the framer, where the 24 DS0s
are reframed as the DS1 transmit output. See Figure 18-29.
NOTE:
The DS1 must be set Out of Service, using the set ds1
command, before you can use loopbacks or test patterns.
NOTE:
For normal operation, the loopback must be disabled (loopdown).
