Abstract

A communications system including a node connected via an ATM connection to a cell Synchronization and Recovery Unit. This allows a number of lower bit rate paths (e.g. n.times.64 kbit/s) to be utilized via a switching center. Another synchronization and recovery unit is connected through an ATM link to a selected recipient interface. A method is provided in which distinct first header portions in idle cells are used to determine the cyclic order in which the ATM cell portions are transmitted down paths and to determine the delay experienced through the paths in order to reconstruct the cells from the portions received from the respective paths. The units determine the delay experienced through the paths and reconstruct cells from the portions passed through respective paths. A personal identification number can be assigned a customer to allow access from one of a number of points and to select a desired service via a control point.
