Telica has expanded its Plexus 9000 Class 4/5 switching platform to include packet-based wireless capabilities, including Gateway Mobile Switching Center (GMSC), Soft MSC Media Gateway and an All-IP Wireless Solution. The announcement adds support for applications that can be applied in wireless network architectures; 2G, 2.5G or 3G, including GSM, GPRS, EDGE, CDMA, TDMA, CDMA2000, and UMTS. Telica said the flat topology of wireless networks is proving difficult to scale because of the large number of highly-meshed trunks required between Mobile Switching Centers (MSCs).
As a Gateway MSC, Telica's Plexus 9000 can be deployed like a Class 4 switch in a wireline network, using TDM, IP, or ATM-based trunking to support Tandem switching and long distance services. Specific to wireless networks, the Plexus 9000 Gateway MSC, which supports IS-41 and GSM MAP services, accepts calls from the PSTN and routes directly to the intended mobile subscriber's Serving MSC, bypassing the Home MSC entirely. The routing efficiency frees up tens of thousands of legacy MSC ports and reduces PSTN interconnect facilities and associated leased line costs through consolidation. The Plexus 9000 could also operate as a wireless media gateway. By working in concert with third party Soft MSCs via industry-standard protocols, the Plexus 9000 can communicate directly to the Radio Access Network, supporting 2G, 2.5G and 3G services. The Plexus 9000 supports TDM, Voice over ATM AAL2 and VoIP, enabling interfaces to the TDM-based A-interface of 2G and 2.5G, and the ATM-based UTRAN of 3G technologies, while supporting IP or ATM-based core network trunks. Telica noted that its platform is already supporting revenue traffic for SIP signaled IP access networks. SIP forms the basis of the 3rd Generation Partners' Project's (3GPP) "Release 5" architecture, where voice calls are converted to IP streams directly from the mobile terminal.
