Usage Examples
The following example specifies that the voice user's terminal outpulse 4 DNIS digits and use the delay
default values (200 ms for digit-delay and 500 ms for cut-through-delay):
(config)#voice user 4444
(config-4444)#dnis-digits 4
Technology Review
The following diagram demonstrates the actions taken by the FXS port and the DNIS delay feature:

status
The diagram shows that the DNIS feature is idle while the FXS port is alerting and waiting for the terminal
to go off-hook. After the terminal is off-hook, the DNIS feature enters the Delay 1 state, specified by the
digit-delay parameter of this command. Entering this state allows sufficient time for any transients audible
on the two-way wire to die away, and for the terminal to attach a digit register. After Delay 1 times out,
DNIS DTMF digits are outpulsed to the terminal. The feature then enters the Delay 2 state, specified by the
cut-through-delay parameter of this command. Entering this state allows for the connected terminal to
finish routing the call. Once the feature enters the Connect state, a two-way voice band connection is
established. Using the dnis-digits command allows you to specify the number of DNIS digits outpulsed
and the duration of both delay periods in this process.
This feature is intended for use with a fax server, where multiple inbound fax numbers are all routed to a
single analog port. To use this feature effectively, follow these steps:
1. Create a voice user account using the command
number assigned can be arbitrary, or it can be one of the desired inbound fax lines.
2. Connect an analog port using the command
3. Assign an alias for each inbound fax line to be steered into the fax server using the command
"<text>" on page
66.
4. Set the number of DNIS digits using the dnis-digits command. These digits must be set in conjunction
with the fax server configuration.
