A communication method between a centralized Unit for Multiple Access and multiple Peripheral units coupled to the Central Unit through a Connecting medium and dispOsition with Multiple Access Communication for implementing Said method

摘要

The Invention relates to a method of Communication in a multiple access system which comprises a Central Unit and a multiplicity deunidades Peripheral connected to the unit centraliISED by a First means of conexionmo nodireccional suitable for transmission depaquetes fixed length Data from the Central Unit to the Peripheral units and MedThrough a Second Connection means to make the transmission monodireccionalapto depaquete s fixed length Data from these Peripheral units to a Central Unit.The Invention Phase foresees inserted in said Packet transmitted on the first Connection means a field that contains a First identifier Information Flow (BFI), groupedWhich identifies a Grouping of multiple virtual paths (VP) Senior downstream (downstream) from one Peripheral Unit.The Invention phase of R alsoallows inserted in said Packet transmitted on the second Connection means a field containing information of a Second identifier grouped Flow(BFI) which identifies a Grouping of a multiplicity of Virtual paths (VP) Q EU enter Upstream (upstream) in a Peripheral Unit.Thanks to these identifiers, it is possible to manage a single centralized Point elaboru00e1ndolasen cells.
