Patent Images
1. A method for implementing telephone network services for a plurality of subscribers in an existing unmodified network provided with co-channel signaling comprising voice and signaling transmissions, said method comprising the steps of:
- connecting a central intelligent node point from outside of said network to said network, said node point being capable of handling approximately 30 out-of-network calls per second made by said subscribers;
routing said signaling transmissions over said node point and converting signaling information contained within said signaling transmissions, at said node point for carrying out said network services; and
routing said voice transmissions around said node point, in response to instructions received from said node point.

Abstract
A method and apparatus for implementing telephone network services in networks provided with co-channel signaling. The signaling is routed over an intelligent node point and signaling information is converted at the node point for carrying out the services. Signaling information is processed separately from network switching equipment and voice transmissions relating to signaling information are not routed over the node point.

7. An apparatus for implementing telephone network services for a plurality of subscribers in an existing unmodified network provided with co-channel signaling comprising voice and signaling transmissions, said apparatus being outside of said network and functioning independently of network switching equipment, said apparatus being capable of handling approximately 30 out-of-network calls per second made by said subscribers, said apparatus comprising:
-
a microprocessor; an internal memory; and an interface arranged to communicate with said network to monitor signaling information directed therethrough, to identify calls having services specified therefor, to convert said signaling information to a format which can be understood by a receiver for carrying out said services, and to direct said calls to said receiver. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
