ISDN interface configuration task list

SmartWare Software Configuration Guide 

Most ISDN terminals support two modes of call setup: En-bloc dialing and overlap dialing. En-bloc dialing 
transports the full called party information in the first SETUP message from the terminal. This means that the 
user must dial the number before going off-hook. Overlap dialing transports the called-party number digit by 
digit, after the first SETUP message, which contains no called-party information at all. Combinations between 
en-bloc and overlap dialing are possible.

Most terminals use ISDN keypad facility messages to transport digits one-by-one in overlap dialing. But some 
terminals, especially terminal adapters for analog devices, might transport the digits only using DTMF tones, 
without associated keypad facility messages.

The 

 command enables the ISDN port for the use with such devices.

Be sure to only use this command when needed. Otherwise, called party information can be corrupted because 
the digits arrive twice, as keypad facility messages and also as DTMF tones.

Procedure: To enable DTMF dialing

Mode: Interface ISDN

Example: Enable DTMF dialing

The following example shows how to enable DTMF dialing for a given ISDN interface.

node>enable
node#configure
node(cfg)#context cs
node(ctx-cs)[switch]#interface isdn MyIsdnIf
node(if-isdn)[myIsdnIf]#dtmf-dialing

The PSTN profile contains the configuration for data/voice transmission on circuit-switched channels (see 
chapter 48,

on page 597). In the case of ISDN interfaces, the PSTN profile 

applies to the ISDN B-Channels associated with the interface.

There is a PSTN profile named default, which always exists in the system. If no different PSTN profile name is 
explicitly configured on the ISDN interface, the profile default is used.

Procedure: To define an alternate PSTN profile for the ISDN interface

Mode: Interface ISDN

node(if-isdn)[if-name]#[no] dtmf-dialing Enables/Disables DTMF dialing (default: disabled)

Defines an alternate PSTN profile to be used for 
this ISDN interface/Reverts the setting to its default 
(use profile PSTN default)
