A virtual private local PCN ring network(VPLPR) is proposed.VPLPR is a virtual logic ring served for digital cordless telephone system and it works on ATM VP cross-connection mechanism.Full-distributed data bases are organized for visitor location registers(VLR)and home location register(HLR).The signalling protocols are compatible upward to B-ISDN.The architecture and some of the main characteristics of VPLPR are given. How to configure the ATM VP cross-connection ring is described.And then a protocol conversion between STM frames and ATM cells in base station controller(BSC)is presented.
