摘要： A communication system typically comprises a number of interconnected broadband-narrowband interfaces (304, 402-404) that together interact to provide a communication resource (400) that can support a call across the system At a time when the communication resource (or a portion thereof) is apparently in place, a terminating node of a broadband-narrowband interface sends a verify-request message (452) backwards across the communication resource. A connection broker (322), coupled to both ends of the communication resource in a particular broadband-narrowband interface (404), is aware of the issuance of the verify-request message, and is therefore able to assess and report, principally, on path connectivity of the communication resource (either within the broadband-narrowband interface or between adjacent interfaces). More particularly, the connection broker expects the arrival of a path connectivity message (454, 460) issued from an end of the broadband-narrowband network responsive to the verify-request message and, as such, can provide an appropriate report (458, 470, 480) upon the timely receipt, or not, of the path connectivity message. Indeed, the verify-request message may also function to confirm path continuity.

摘要： A number of narrow band networks are interconnected via a broad band network having a signalling protocol different from that or those of the narrow band networks. Calls between terminals associated with first and second narrow band networks are set up by the selection by a call server of a phantom trunk between the networks. This phantom trunk is used to relay the addresses of the two terminals to be connected. By recognizing that two connection requests have been received at opposite ends of the same phantom trunk, a processor in the second network determines that a connection between the terminals via the broad band network is required. Selection of the phantom trunk and sending of address messages is effected via a selected one of a number of identical connection brokers coupled to the call server. The workload of the call server is shared among the connection brokers coupled thereto.
