An arrangement for adapting a PCM (pulse code modulation) switch to control and communicate with a CDMA (code division multiple access) cell site for communication the wireless CDMA stations that communicate with that cell site. A protocol converter converts between signals for controlling integrated services digital network (ISDN) stations and signals for controlling a cell site, so that the cell site operates as if it were being controlled by a wireless switching center and the switch acts as if it were controlling ISDN stations. In the switch, a switchable connection is established between land based inputs and intermediate ports and a separate set of permanent connections is established between the intermediate ports and the PCM/packet converters. Advantageously, a switch designed to serve ISDN stations can be readily adapted to serve cell sites for serving wireless CDMA stations.
