NURSE CALL SYSTEM, INTERFACE UNIT, AND NURSE CALL CONNECTION METHOD

In nurse call systems where communication between a plurality of slave units and a plurality of extension terminals is possible, a nurse call controller serving the slave units and a private branch exchange serving the mobile terminals have been connected to each other through a nurse call adaptor; thus, there is a need for one such nurse call system that does not require a nurse call adaptor. Provided is an interface unit which is connected to a nurse call controller through a plurality of ISND basic interfaces, connected to a private branch exchange through an ISDN primary rate interface, and performs interface conversion therebetween. 1. A nurse call system for forming a speech path among a plurality of slave units and a plurality of extension terminals to conduct a call , comprising:a nurse call controller accommodating the plurality of slave units;a private branch exchange accommodating the plurality of extension terminals; andan interface unit provided between the nurse call controller and the private branch exchange, connected with the nurse call controller through a plurality of ISDN basic interfaces, connected with the private branch exchange through an ISDN primary rate interface, to control all of data channels of the plurality of ISDN basic interfaces with one control channel of the ISDN primary rate interface and to allocate the data channels of the plurality of ISDN basic interfaces on the nurse call controller side to data channels of the ISDN primary rate interface on the private branch exchange side in order from a top.2. (canceled)3. (canceled)4. The nurse call system according to claim 1 , wherein the interface unit is accommodated in the private branch exchange.5. An interface unit claim 1 , which is:configured to be used in a nurse call system for forming a speech path among a plurality of slave units and a plurality of extension terminals to conduct a call, comprising a nurse call controller accommodating the plurality of slave units, and a ...

NURSE CALL SYSTEM, NURSE CALL CONVERSION UNIT, NURSE CALL CONNECTION METHOD, AND PROGRAM

In nurse call systems that enable communication from a plurality of cordless handsets with a plurality of extension terminals carried by nurses belonging to a group, a nurse call conversion unit is provided between a nurse call control device and a private branch exchange. A call signal for a group representative call in which only an identification number for a group is given is transmitted by the nurse call conversion unit from the nurse call control device to the private branch exchange. From this call signal, the private branch exchange generates a call signal for extension terminals belonging to a group and calls the extension terminals.

Nurse call system, nurse call conversion unit, nurse call connection method, and program

In nurse call systems that enable communication from a plurality of cordless handsets with a plurality of extension terminals carried by nurses belonging to a group, the line efficiency is poor when an extension terminal belonging to the group is called from a cordless handset because the number of channels that are occupied between a nurse call control device and a private branch exchange corresponds to the number of extension terminals belonging to the group. In this nurse call system, a nurse call conversion unit is provided between a nurse call control device and a private branch exchange. A call signal for a group representative call in which only an identification symbol for a group is given is transmitted by the nurse call conversion unit from the nurse call control device to the private branch exchange. From this call signal, the private branch exchange generates a call signal for extension terminals belonging to a group and calls the extension terminals.
