ISDN terminal equipment-resident mechanism for determining service profile identifiers and associated telecommunication switch protocol
First Claim
1. A method for enabling a digital communications device to place a call via telecommunications equipment, using a service profile identifier (SPID) that is required for conducting digital communications via said telecommunications equipment, comprising the steps of:
- (a) attempting to register one or more SPIDs derived from one or more user-supplied local directory numbers and a selected one of a plurality of respectively different SPID formats in an automatic fashion; and
(b) in response to successful registration of said one or more SPIDs in step (a), automatically configuring said digital communications device for the placement of calls using the one or more SPIDs that has been successfully registered.

Abstract
The inability of an ISDN equipment user to properly configure ISDN terminal equipment, even when provided with correctly assigned switch protocol, SPID and LDN parameters by a telephone service provider, is successfully remedied by a SPID/switch protocol detector. Upon being invoked by the user, the routine proceeds to conduct an iterative search of stored SPID formats associated with different central office switch protocols. SPIDs are assembled in accordance with the iteratively accessed SPID formats and directory number information that has been entered by the user. If an attempt to register a SPID is successful, the routine places a test call. If the test call is successful, the SPID and its associated switch protocol will have been identified, and the terminal equipment may place a call.

18. A method for enabling integrated services digital network (ISDN) terminal equipment to place a call via a central office switch, using a service profile identifier (SPID) that is required for conducting digital communications via said central office switch, comprising the steps of:
-
(a) storing local directory number information supplied by a user, and a plurality of respectively different tables of SPID format entries associated with respectively different central office switch protocols; (b) iteratively stepping through SPID format entries of said tables and, for each SPID format entry, generating one or more SPIDs in accordance with contents of said SPID format entries and said local directory number information; (c) for a respective step iteration in step (b), attempting to register the one or more SPIDs generated therefrom; (d) in response to successful registration of said one or more SPIDs in step (c), placing a test call via said switch to a local directory number supplied by said user; and (e) in response to successful placement of said test call in step (d), configuring said digital communications device for the placement of calls using said one or more SPIDs generated in step (b). - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
