ISDN configuration task list

SmartWare Software Configuration Guide 

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,

Mode: q931

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

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.

tocol. Currently only CC-ISDN is supported.

Bind the Q.931 protocol to an existing call 
control interface.
