Abstract
A communications system, in which a plurality of remote modems communicate over a twisted-pair telephony infrastructure, each remote modem being communicatively coupled to a corresponding subset of user devices. The system also comprises a healthcare information system (HIS) server capable of supporting healthcare information sessions established with individual user devices from the overall set of user devices, the HIS server being connectable to a core hospital network. Finally, the system comprises a head-end unit connected between the HIS server and the telephony infrastructure. The head-end unit comprises a bank of centralized modems operative to exchange out-of-telephony-band signals with respective ones of the remote modems over the telephony infrastructure to permit establishment of healthcare information sessions between the overall set of user devices and the HIS server. In this way, an existing telephony infrastructure in a hospital can be re-used to deliver healthcare information services to the point of care.
