TR TSY 000573 : ISSUE 1

Business Group Call Waiting notifies a busy user of an additional call, and provides a procedure that allows acceptance and handling of the call. This new TR is a part of the LATA Switching Systems Generic Requirements (LSSGR), TR TSY-000064. Business Group Call Waiting, FSD 01-02-1205, was previously included in TR TSY-000522 of the LSSGR. TR TSY-000522 is now being separated into individual Technical References for convenience of purchasing, filing, and updating. There are no new requirements for Business Group Call Waiting.
