Peer Protocol-Rejects CCP
If the peer does not actually support PPP compression, it will most likely Protocol-Reject
the CyberSWITCH’s attempt to negotiate CCP. In this case, the CyberSWITCH will
abandon its attempt to use compression and the connection will operate uncompressed.
The incoming frame from the peer contains a PROT-REJ, whose 1st two hex octets in the
trace indicate the CCP protocol (0x80FD).

The CyberSWITCH does not have Compression ENABLED
In this case, the CyberSWITCH will respond to all attempts by the peer to open CCP with
a TERM-ACK frame. The connection will operate uncompressed. (Note: a device that
supports compression but has it disabled will typically do the exact same thing).

1.
To verify bandwidth reservation, configure several different combinations of lines and devices.
2.
Attempt outbound and inbound calls.
3.
Verify the proper success and reject of each.
4.
If there is a problem, check the configuration of the profiles and how they are assigned to each
device (refer to
device (refer to
in the Configuring Call Control chapter).
