What is AutoSPID?
(North America only)
AutoSPID is a new National ISDN protocol feature which enables the
DIVA T/A to download a list of Service Profile Identifiers (SPIDs),
Directory Number and Call Type information from the ISDN line, and
to determine whether the SPIDs are currently initialized by other
devices.
Note: Check with your ISDN service provider to determine if they
support the AutoSPID feature.
This feature effectively eliminates the need for you to configure any
ISDN parameters.
AutoSPID works in the following manner:
If there are no SPIDs configured, then AutoSPID attempts to
determine and then assign SPIDs and DNs to the location designated
to store the AutoSPID parameters. The location for storing your
AutoSPID information can be configured on the Advanced
Configuration page.
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 configured manually, ISDN will fail to
initialize (the D-LED will flash).
The only way to use the DIVA T/A without entering SPIDs, is to
configure the ISDN numbers for Non-Initializing Terminal mode.
