Abstract

Abstract An Asynchronous Transfer Mode (ATM) network comprising a plurality of ATM switches may be arranged so that it may receive for routing telephone calls originating at Synchronous Transfer Mode (STM) switches. This may be done in the ATM network by accumulating voice signals as they are received from a STM switch and forming an ATM data-cell payload when the accumulation includes a predetermined number of the voice signals, e.g., 48 voice signals. The payload and a header, including a virtual channel identifier determined as a function of the identity of the STM trunk over which the voice signals were received, may then be supplied to an associated ATM switch for routing to an intended destination.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 131 words
A method of processing voice signals received from a STM switch via a trunk for presentation to an ATM switch of an ATM network, said voice signals being associated with a particular call, said trunk having a predetermined identity, said method comprising the steps of accumulating said voice signals as they are received from said STM switch to form a payload of an ATM data cell, said payload comprising a predetermined number of said voice signals, responsive to accumulating said predetermined number of voice signals and forming said payload, translating said trunk identity into a predetermined virtual channel identifier and forming a cell header comprising at least said virtual channel identifier, and supplying said cell header and said payload as said data cell to an input port of said ATM switch.
Claim 2
Independent Claim 131 words
A method of processing voice signals received from a STM switch via a trunk for presentation to an ATM switch of an ATM network, said voice signals being associated with a particular call, said trunk having a predetermined identity, said method comprising the steps of accumulating said voice signals as they are received from said STM switch to form a payload of an ATM data cell, said payload comprising a predetermined number of said voice signals, responsive to accumulating said predetermined number of voice signals and forming said payload, translating said trunk identity into a predetermined virtual channel identifier and forming a cell header comprising at least said virtual channel identifier, and supplying said cell header and said payload as said data cell to an input port of said ATM switch.
Claim 3
Dependent Claim 48 words
The method of claim 1 wherein said trunk identity includes an identity of an associated trunk subgroup and wherein said step of translating includes the step of translating the identity of said trunk subgroup into a virtual path identifier and including said virtual path identifier in said header.
Claim 4
Dependent Claim 37 words
The method of claim 1 wherein said step of translating the identity of said trunk performs said translation on a one-to-one basis such that said virtual channel identifier is made to equal the identity of said trunk.
Claim 5
Independent Claim 120 words
A method of processing voice signals in a ATM network, said voice signals being received from a STM switch via a STM trunk having a predetermined identity, said method comprising the steps of at an interface between said trunk and an associated ATM switch, forming said voice signals as they are received into a series of data octets, completing said series when the number of octets in said series is sufficient to form a payload of an ATM data cell, translating said trunk identity into a virtual channel identifier and forming a data cell header comprising at least said virtual channel identifier, and supplying said payload and said header to said associated ATM switch for routing to an intended destination.
Claim 6
Independent Claim 120 words
A method of processing voice signals in a ATM network, said voice signals being received from a STM switch via a STM trunk having a predetermined identity, said method comprising the steps of at an interface between said trunk and an associated ATM switch, forming said voice signals as they are received into a series of data octets, completing said series when the number of octets in said series is sufficient to form a payload of an ATM data cell, translating said trunk identity into a virtual channel identifier and forming a data cell header comprising at least said virtual channel identifier, and supplying said payload and said header to said associated ATM switch for routing to an intended destination.
Claim 7
Dependent Claim 48 words
The method of claim 4 wherein said trunk identity includes an identity of an associated trunk subgroup and wherein said step of translating includes the step of translating the identity of said trunk subgroup into a virtual path identifier and including said virtual path identifier in said header.
Claim 8
Dependent Claim 37 words
The method of claim 4 wherein said step of translating the identity of said trunk performs said translation on a one-to-one basis such that said virtual channel identifier is made to equal the identity of said trunk.
