Among the fastest growing telecommunications markets is the wireless market, where networks use code division multiple access (CDMA). In part, the popularity of CDMA among wireless service providers results from CDMA's use of packet switching for routing voice, data, and signaling. However, CDMA callers are usually talking to users of wireline telephones on the public switched telephone network (PSTN). This paper examines Lucent Technologies' CDMA packet switched network (PSN), which uses asynchronous transfer mode (ATM) to interconnect the 5ESS ® PSN elements. We discuss how voice packets go from the CDMA phone to several cell sites, through the ATM-based PSN, to the circuit-switched PSTN. We show how CDMA provides superior voice clarity and quiet soft hand-offs as the CDMA caller travels among cell sites. We discover that the 5ESS PSN is highly reliable, scaleable, and flexible, and supports a high capacity of traffic. Finally, we look at plans to evolve the architecture to increase its robustness and capacity.
