ABSTRACT:
A method and apparatus are used for accounting for last and out-of-sequence interprocessor messages in a multiprocessor telephone switching system. Each message is assigned a sequence number by the sending processor. Upon reception of messages, the receiving processor analyzes the sequence numbers to ascertain their proper order and if any messages are missing. The identities of missing messages are entered in a table which is periodically updated.
