Configuring DTMF dialing (optional)
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.
DTMF dialing
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
Step
1
node(if-isdn)[if-name]#[no] dtmf-dialing Enables/Disables DTMF dialing (default: disabled)
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
Configuring an alternate PSTN profile (optional)
The PSTN profile contains the configuration for data/voice transmission on circuit-switched channels (see
chapter 48, "PSTN profile configuration"
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
Step
1
