Detailed description of Alphanumeric Dialing

Last Updated : Feb 24, 2021 |

With Alphanumeric Dialing, a user can place a data call with Data Call Setup and an alphanumeric string or alpha-name for the call-destination address. For example, a user can type 9+1-800-telefon instead of 9+1-800-835-3366 to place a call. Users need to remember the alpha-name of the far-end terminating point.

With Alphanumeric Dialing, you can change a mapped string (digit-dialing address) without informing all users of a changed dial address. Users dial the alpha name.

When a user enters an alphanumeric name, the system converts the name to a sequence of digits according to an alphanumeric-dialing table. If the name that the users enter is not in the table, the system denies the call attempt. The user receives an Invalid Address message (DCP) or a Wrong Address message (ISDN-BRI).

As data terminals use DCP or ISDN-BRI data modules to access the switch, dialing procedures vary:

  • For DCP, at the DIAL prompt, users type the alphanumeric name and press Enter.

  • For ISDN-BRI, at the CMD prompt, users type d, a space, the alphanumeric name, and press Enter.
