PVC Loopback
The PVC Loopback loops frames back to the selected interface on a per-PVC
basis. This test logically (not physically) loops back frames received from another
FrameSaver device through the selected frame relay PVC to the same device.
Send Pattern
This test sends packets filled with a hexadecimal 55 test pattern and sequence
number over the selected interface and DLCI to another FrameSaver device.
To send a pattern test on a link:
If the CIR is zero, the pattern will be sent at a rate of 1000 bps.
