Abstract
Apparatus and method is disclosed for storing and subsequently transmitting later messages for system pagers with acknowledge back capability that nevertheless fail to acknowledge back in the first instance. Addresses are retransmitted for pagers initially failing to acknowledge back on a continuous periodic basis until such acknowledge back is received, at which time the message intended therefor is sent, or a predetermined time period expires.
