Abstract

Abstract A loop carrier system includes a home local area network having plural telephone modules and a hub coupled to in-home telephone wiring. The telephone modules and the hub communicate voice signals over the in-home wiring in a dedicated frequency band above baseband POTS. The hub converts between voice signals and voice packets and is connected to a network access device for transferring the voice packets from the home local area network to a telecommunications network which routes the voice packets to a gateway. The gateway converts between the voice packets and a circuit format compatible with a local digital voice switch. The gateway includes an ATM switch and a call processing adjunct coupled to the ATM switch. The call processing adjunct controls the conversion between voice packets and the circuit format at the ATM switch. The call processing adjunct communicates with the home local area network using a first signaling protocol such as Media Gateway Control Protocol, Session Initiation Protocol or H.323, and with the local digital switch using a second signaling protocol such as GR-303 for controlling call processing in the communication system.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 146 words
In a communication system having a home local area network for transmitting and receiving voice packets to and from a wide area network, a gateway for coupling to the wide area network for converting between the voice packets and a circuit format compatible with a local digital voice switch, the gateway comprising: an ATM switch; and a call processing adjunct coupled to the ATM switch wherein the call processing adjunct controls the conversion between voice packets and the circuit format at the ATM switch, wherein the call processing adjunct communicates with the home local area network using a first signaling protocol and with the local digital switch using a second signaling protocol for controlling call processing in the communication system and wherein the first protocol is selected from among Media Gateway Control Protocol, Session Initiation Protocol and H.323 and the second protocol is according to GR-303.
Claim 2
Dependent Claim 146 words
In a communication system having a home local area network for transmitting and receiving voice packets to and from a wide area network, a gateway for coupling to the wide area network for converting between the voice packets and a circuit format compatible with a local digital voice switch, the gateway comprising: an ATM switch; and a call processing adjunct coupled to the ATM switch wherein the call processing adjunct controls the conversion between voice packets and the circuit format at the ATM switch, wherein the call processing adjunct communicates with the home local area network using a first signaling protocol and with the local digital switch using a second signaling protocol for controlling call processing in the communication system and wherein the first protocol is selected from among Media Gateway Control Protocol, Session Initiation Protocol and H.323 and the second protocol is according to GR-303.
Claim 3
Dependent Claim 12 words
The gateway of claim 1 wherein the voice packets comprise ATM cells.
Claim 4
Dependent Claim 17 words
The gateway of claim 2 wherein the ATM cells are formatted according to an ATM Adaptation Layer.
Claim 5
Dependent Claim 14 words
The gateway of claim 3 wherein the ATM cells include AAL1-type and AAL5-type cells.
Claim 6
Dependent Claim 27 words
The gateway of claim 4 wherein the ATM switch includes a converter module responsive to the call processing adjunct for converting between AAL1 cells and PCM samples.
Claim 7
Dependent Claim 26 words
The gateway of claim 5 wherein the converter module includes means for inserting PCM samples into DS0 format for connection to the local digital voice switch.
Claim 8
Dependent Claim 27 words
The gateway of claim 4 wherein the ATM switch is configurable to route AAL5 cells to the call processing adjunct for conversion to GR-303 call processing messages.
