Check this check box if your service provider requires SPIDs.
Some service providers use SPIDs to define the services that are
subscribed to by an ISDN device that is accessing the ISDN service
provider. The service provider assigns the ISDN device one or more
SPIDs when you first subscribe to the service. If you are using a
service provider that requires SPIDs, your ISDN device cannot
place or receive calls until it sends a valid, assigned SPID to the
service provider when the device accesses the switch to initialize
the connection.
Currently, only the DMS-100 and NI switch types require SPIDs.
The AT&T 5ESS switch type may support a SPID, but we
recommend that you set up the ISDN service without SPIDs. In
addition, SPIDs have significance only at the local access ISDN
interface. Remote routers never receive the SPID.
A SPID is usually a 7-digit telephone number with some optional
numbers. However, service providers may use different numbering
schemes. For the DMS-100 switch type, two SPIDs are assigned,
one for each B channel.
Enter the SPID for the first BRI B channel provided to you by your
ISP.
Enter the SPID for the second BRI B channel provided to you by
your ISP.
Enter the phone number of the remote end of the ISDN BRI or analog modem
connection. This is the phone number that the ISDN BRI or analog modem
interface will dial whenever a connection is made. The dial string is provided to
you by your service provider.
