Configuring Q.931 encapsulation
This command specifies the next protocol or application has to be attached to the Q.931 protocol. In case of
ISDN this will always be the CC-ISDN (Call Control) application. For this case also a binding to a pre-created
ISDN interface is necessary. For information about creation and configuration of an ISDN interface please see
Chapter 34, "ISDN interface configuration"

Debugging ISDN

For the investigation of possible Q.921/Q.931 protocol problems or to get call signaling information, there
exists a debug command with the options 'event' and 'error'. The command can be applied to the port on
which ISDN is configured and has a further option to switch on or off a specific ISDN layer. In addition, the
'show port isdn' command can be used to printout information about the current state and statistic informa-
tion about received and transmitted frames.
Mode: Operator execution

Purpose
Specify B-channel allocation strategy (Default:
ascending)
The numbering mode defines how the avail-
able time slots are filled. The cyclic modes use
a "round-robin" implementation. The "up"
and "down" modes define whether the time
slots are filled at the lowest or highest avail-
able slot, i.e. up means that always the lowest
available slot is used, down uses always the
highest available slot.
Purpose
Enables/Disables the next application or pro-
tocol. Currently only CC-ISDN is supported.
Bind the Q.931 protocol to an existing call
control interface.
