This feature makes use of DNIS (Dialed Number Identification Service), a feature that can be implemented on
your T1/E1. DNIS is a telephone service that identifies for the receiver or a call, the number that the caller
dialed. DNIS works by passing the touch-tone digits (dual-tone multi-frequency or MF digits) to the destina
-
tion for use by the terminating device.
The RAS uses its ability to capture DNIS information to provide the customer with the ability to set up dial-in
parameters for their dial-in clients based on the phone number dialed and the physical WAN port they have
dialed into or just the number dialed. The DNIS management feature allows you to configure the authentica
-
tion method and the IP address pool.
The Manage DNIS Window contains the following items:
• Information about DNIS configurations set-up—to view or modify individual DNIS configurations, select
an ID in the ID column. For more information about modifying a DNIS configuration, refer to

Entry Window” on page 79
