What number should ISDN BRI client use to dial into ISDN PRI (spid?)

Sorry for the apparently easy question, but what number would an router using BRI as a backup use to dial into a PRI? BRI-to-BRI uses a SPID, but what number would you dial when dialing into an ISDN PRI.

Thanks!

Thanks! I hadn't configured a PRI before, and was thinking SPID.

Regards,
