Parameter count: Maximum number of VCs, ranging from 1 to 8.
Description Use the
x25 vc-per-map command to set the maximum number of VCs for
connections with the same destination device.
Use the
undo x25 vc-per-map command to restore the default.
The default is 1.
If the parameter is greater than 1, and the sending window and the sending
queue of VC are filled full, the system will create a new VC to the same
destination. If the new VC cannot be created, packets will be discarded.

its value ranges from 0 to 4095. If hic (highest incoming-only channel) is set to 0,
lic (lowest incoming-only channel) must also be set to 0, which indicates that the
incoming-only channel section is disabled.
in-channel loc hoc: Lowest and highest outgoing-only channels of X.25 VC, and
its value ranges from 0 to 4095. If hoc (highest outgoing-only channel) is set to 0,

outgoing-only channel section is disabled.
