All BellSouth/FastAccess virtual circuits use a VPI/VCI of 8/35 respectively. If you have a modem that was not supplied by BellSouth you must make sure your VPI/VCI is correct or you will not be able to authenticate.
Important Note: Not having the correct VPI/VCI on a modem will not prevent a modem from synching.
