AI Technical Summary

Benefits of technology

The invention provides a method and system for enhancing the provision of voice services via packet switched facilities using an associated attachment device. The technical effects include storing information about voice terminals accessible through the associated voice switch in multiple attachment devices and generating requests between attachment devices for information about voice terminals. This allows for better information sharing and cooperation among attachment devices. The system also utilizes Switched Virtual Channels and allows for cooperation among attachment devices in multiple frame relay networks. Overall, the invention improves the efficiency and reliability of voice services in packet switched facilities.

Problems solved by technology

However, packet switching networks lack other services which are typically found in the voice dedicated network.
One of the difficulties with carrying voice services over packet switched networks is the problem of providing the FRAD or the like with this information.

Embodiment Construction

[0023] FIG. 1 shows a frame relay network 100. Included in the frame relay network 100 and not specifically illustrated in FIG. 1 are a plurality of data sources and sinks (here the term data is used to distinguish the form of the information from voice). FIG. 1 also shows several PBXs 201-203 which employ the services of the frame relay network to transmit voice. Coupled between each voice switch PBX 201-203 and the frame relay network 100 is an associated attachment device, particularly a Frame Relay Attachment Device (FRAD) such as FRADs 301-303.

[0024] FIG. 1 also shows the connection of each PBX to the local Public Switched Telephone Network or PSTN (local PSTN refers to the portion of the PSTN which is accessible to the associated PBX without incurring toll charges). Particularly, each PBX (including each of the illustrated PBX's 201-203) is capable of dialing into the local PSTN network and reaching thousands of telephone terminals. Because of typical calling tariffs, there is...

Abstract

Voice services provided over a packet switched facility such as a Frame Relay network are enhanced with routing capability by providing for attachment devices which, on initialization with the network, attempt to discover other similar attachment devices on the network. Thereafter the attachment devices exchange information on terminal accessibility to improve connectivity over the network.

Description

[0001] The invention relates to telecommunications and more particularly to improvements in digital provisioning for voice services.BACKGROUND OF INVENTION[0002] For the majority of the history of telecommunications, voice has been the predominant application. Indeed, only recently has data transmission become significant. Nevertheless, the advances that have been made in data communications have been so profound that it is not unusual for modern data communications technology to be applied to carrying voice, in addition to data.[0003] Many of the improvements in data communications relate to packet switching. Different varieties of data communication technology falling under the class of packet switching include Frame Relay (hereinafter also FR), Asynchronous Transfer Mode (ATM), Internet Protocol (IP), voice over Internet Protocol, SMDS, cell relay networks or the like.[0004] Packet switching networks provide a payload transport capability which is applied to voice communication p...
