Low cost acknowledge-back system for a pager using existing infrastructure

摘要

A low cost acknowledge-back system for a pager includes a small, portable plug-in module with a telephone connector for coupling to an existing telephone network. Paging devices interact with plug-in modules through a wireless infrared (IR) link. When a paging device comes within communication range of a module, automated interaction therebetween allows the paging device to acknowledge to a paging system successful delivery of a given paging message. The system further includes multiple levels of acknowledgement including acknowledgement of message receipt and message read events at the paging device. Further, the system includes automatic and manual response functions allowing the user of the paging device to initiate automatically or manually a telephone connection using the telephone number of a telephone number message to respond to a given telephone number message.
