PAGING SYSTEM WITH IMPROVED ACKNOWLEDGE-BACK CAPABILITIES |
摘要 |
A paging system (10) comprising a centrally located terminal (12) and a plurality of remote pager units (24) is disclosed wherein both automatic and manual acknowledge back signalling is provided. An appropriate acknowledge back signal by a called pager within a set interval indicates the message was duly received and understood which is so indicated to the initiating caller. Failure to respond within the set interval causes the pager unit to send back a negative response which is likewise so indicated to the initiating caller.
