Interswitch telephone status monitoring
First Claim
1. A method of monitoring a telephone station status from a monitoring terminal comprising the steps of:
- initializing translation information of a switch for controlling said monitoring terminal to record that a status of the related monitored station is to be monitored by said monitoring station;
maintaining a status of said monitored station in a monitoring terminal;
responsive to detection of a change in the status of said monitored station, signaling said monitoring terminal information describing said change; and
responsive to receipt of said information, updating, in said monitoring terminal, the status of the monitored station whose status had changed;
characterized in that said monitoring terminal is on a different switch than said monitored terminal, and that the step of signaling comprises the steps of;
detecting the status change in a switch serving the monitored station;
transmitting a signaling message from the switch serving the monitored station to the switch serving the monitoring station; and
transmitting a signaling message from the switch serving the monitoring station to the monitoring station for informing the monitoring station of the status change;
wherein the switch serving the monitoring station is geographically separate from the switch serving the monitored station;
wherein the monitoring station can monitor the status of the monitored station, but not speech signals from and to said monitored station.

Abstract
A method and apparatus for monitoring stations from a monitoring terminal wherein at least one of the monitored stations is served by a different switch than that serving the monitoring station. Changes of status are reported by a monitored station to the switch serving the monitored station and, if that switch is not the switch serving the monitoring station, the switch serving the monitored station transmits a common channel signaling (CCS) signaling system 7 (SS7) message to the switch serving the monitoring terminal. Advantageously, this permits an attendant at the monitoring terminal to serve users not connected to the switch serving the monitoring terminal.

12. A switching system for controlling operation of attendant terminals for monitoring calls on a plurality of related monitored telephone stations comprising:
-
a switching network for establishing connections to said monitoring terminal; and control means for controlling establishment of connections to said monitoring terminal, and for controlling the transmission of control messages to said monitoring terminal; said control means comprising means for; initializing translation information of said switch to record that a status of a related monitored station is to be monitored by said monitoring station; and means, responsive to detection of a change in the status of said monitored station, for transmitting to said monitoring terminal information describing said change; characterized in that a switch serving said monitored station is geographically separate from the said switching and wherein, the means for transmitting to said monitoring terminal, information describing said change, comprises; means for receiving a message from said switching system serving said monitored station; and means, responsive to receipt of said message from said switch serving said monitored station, for transmitting a message to said monitoring station to update a status display of said monitoring station; wherein said monitoring station can not monitor speech signals to and from said monitored station.
