Ingress Table

The ingress table is a collection of network telephone numbers (other than the local telephone numbers) arranged sequentially according to priority. The ingress table is only a means of allowing call processing to begin before you have completed dialing. The originating Passport 4400 unit will begin processing the call when one of the following four things happens:

• The maximum number of dialed digits has been reached.
• The interdigit timeout has occurred.
• A # has been dialed (and end of dial signaling is enabled).
• The digits dialed so far match an entry in the ingress table.

Each network telephone number may or may not include a manipulation string. If included, the manipulation string will modify a user-dialed telephone number to another network telephone number. This number is then transmitted to the Voice Network Call Server (VNCS) in the Passport 6400 for address resolution (see the RSI/RSA section). If your system does not include a Passport 6400, then network address is resolved by the Network Address Server (NAS) as described in the NAC/NAS section. Ultimately, the resolved number is transmitted to the destination voice channel.

You may use one of two procedures to set the ingress table:

• Configurator Procedure for Setting the Ingress Table
• CLI Procedure for Setting the Ingress Table

Note: The manipulation string in the ingress table is unrelated to the manipulation string in the egress table.
