摘要：The invention concerns a telecommunication network using the W-CDMAprotocol comprising a variety of base stations (BS) communicating with each other via acentral Radio Network Controller (RNC) by an ATM based data connection via an IUBinterface, whereby at least one of the base stations (BS) is comprising a variety of radiosectors (1, 2, 3, ...n) with physically distributed AAL-2 based termination points (TP), eachtermination point having an AAL-2 over ATM structure where different call IDs aremapped into respective ATM virtual connections (ATM/VC) under the control of a controlunit timer (CU-timer) having a determined delay time, all AAL cell streams being sentparallel to each other to an ATM switching unit (AXU) via a UTOPIA interface. In order toincrease the efficiency of the system without a reduction of the maximum allowed delay,the ATM switching unit comprises a multiplexing unit (AAM CPS MUX) for multiplexingAAL-2 connections of the different termination points (TP) into one single ATM virtualconnection to be processed by the ATM switch.
