Automated SPID Selection

(AutoSPID) (North America only)

AutoSPID is a new National ISDN protocol feature that enables the DIVA T/A to download a list of Service Profile Identifiers (SPIDs), Directory Number (DN) and Call Type (CT) information from the ISDN line. It also enables the DIVA T/A to determine whether other devices currently initialize the SPIDs.

Note: Check with your ISDN service provider to determine if they support the AutoSPID feature.

This feature eliminates the need for you to configure any ISDN parameters.

AutoSPID works in the following manner:

•If there are no SPIDs configured, or if current SPIDs are incorrectly configured, then AutoSPID attempts to determine and then assign SPIDs and DNs to the location designated to store the AutoSPID parameters.

•If AutoSPID fails to detect the SPIDs, try entering the DNs (in a 10- digit format) and the DIVA T/A will attempt to perform generic SPID guessing.

•Unless the SPIDs and DNs are configured correctly (whether through AutoSPID, SPID guessing, or manually) ISDN will fail to initialize (the D-LED flashes).

The only way to use the DIVA T/A without using SPIDs is to configure the port as a Non-Initializing Terminal. Refer to the next section “Non-Initializing Terminal Mode”, for more information.
