摘要：
During initiation procedure between subscriber stations and access network adhering to CDMA standards, (e.g., IS-95 and IS-2000) the subscriber station receives a Sync Channel Message. Due to a design/manufacturing error, certain subscriber stations adhering to the IS-95 fail to ignore a portion of the Sync Channel Message, intended for a proper operation of subscriber stations adhering to the IS-2000. This causes a failure of the IS-95 subscriber stations' operation. The disclosed invention describes embodiments allowing the faulty subscriber stations to operate on an access networks build in accordance with both IS-95 and IS-2000 standards.
