Abstract
A serial interface for interfacing communications traffic, e.g. frame based voice traffic, with a cell or packet based communications network, the interface comprises; a transmit unit and a receive unit, the units being coupled via a first serial line and one or more further serial lines. The transmit unit has packetising means for packing the communications traffic into micro-packets, each having a header portion containing control information and a payload portion. The payloads and control information are transmitted in parallel respectively over the first and further serial lines to the receive unit The receive unit has means for receiving the transmitted payloads and for relating the corresponding control information thereto.
Claims16
A serial interface for interfacing frame based communications traffic with a cell or packet based communications network, the interface comprising;
- means for segmenting the frame based traffic into micro-packets each consisting of a payload and a header containing control information, and means for transmitting said payload and control information in parallel over separate serial links.
A serial interface for interfacing communications traffic with a cell or packet based communications network, the interface comprising;
- a transmit unit, a receive unit, a first serial link and one or more further serial links therebetween, wherein the transmit unit has packetising means for packing the communications traffic into micro-packets, each having a header portion containing control information and a payload portion, first serial transmission means for transmitting the payload portion of each said micro-packet over the first serial line to the receive unit, and further transmission means for transmitting the control information in parallel with the payload information over the one or more further serial lines to the receive unit, and wherein the receive unit has means for receiving the transmitted payload and for relating the transmitted control information thereto.
An interface arranged to convey variable length voice and data information packets between processing devices in an asynchronous adaptation arrangement, wherein the voice and data information packets are conveyed in a serial manner within micro-packets whereby to obviate the use of null or padding data.
A method of conveying variable length voice and data information packets over an interface between processing devices in an asynchronous adaptation arrangement, wherein the voice and data information packets are conveyed in a serial manner within micro-packets whereby to obviate the use of null or padding data.
A method of interfacing frame based communication traffic with a cell or packet based communications network, the method comprising segmenting the frame based communications traffic into micro-packets each a consisting of a payload and a header containing control information, and transmitting said payload and control information in parallel over separate serial lines.
A method of interfacing communications traffic with a cell or packet based communications network, the interface comprising;
- a transmit unit, a receive unit, a first serial line and one or more further serial lines therebetween, wherein the method comprises packetising the communications traffic into micro-packets, each having a header portion containing control information and a payload portion, transmitting the payload portion of each said micro-packet over the first serial line to the receive unit, transmitting the control information in parallel with said payload transmission over said one or more further serial lines and at the receive unit receiving the transmitted payload and relating the transmitted control information.
