BERKELEY, Calif.--(BUSINESS WIRE)--Oct. 22, 2002

Adax, the industry leader in high performance communications and signaling infrastructure, today announced the release of the PCI Mezzanine Controller (PMC) version of its HDC signaling protocol controller. The HDC-PMC offers a powerful high-density solution to expand the capabilities of legacy SS7 systems or sit within SS7/IP gateways to connect the PSTN with the Internet and other IP networks.

The PMC form factor enables full slot space utilization, maximum development flexibility in next generation infrastructure and provides a totally scalable and cost effective solution. The HDC-PMC complements the existing PCI and cPCI intelligent controller offerings from Adax, giving customers maximum platform choice. The HDC-PMC has been designed specifically for customers building Signaling Gateways, Media Gateway Controllers, Serving GPRS Support Nodes (SGSNs) and Gateway GPRS Support Nodes (GGSNs) in GPRS and 3G networks.

The HDC-PMC can be configured with a SBC as a single board signaling gateway, for the most cost effective single slot solution for infrastructure developers in converged and next generation network environments. The controller can support a complete SS7 stack over T1/E1 interfaces and SIGTRAN protocols over Ethernet ports (which provide SS7 transport over IP). The HDC-PMC supports the latest SIGTRAN protocol suite including Stream Control Transport Protocol (SCTP), M3UA, M2UA or M2PA. This SIGTRAN support is in addition to traditional SS7 MTP-2 64k and 2Mb High Speed Signaling, Frame Relay, X.25, LAPB/D/F and LAPV5. T1/E1 connections communicate to Signaling Transfer Points (STPs) and Signaling Control Points (SCPs) on one side of the network and Ethernet ports interface to the Media Gateway Controller/IP network.

The HDC-PMC can also be deployed within GPRS networks for SGSNs and GGSNs, or SGSNs and BSSs. The HDC-PMC can support simultaneous Frame Relay for the Gb interface alongside SS7 for the Gc/Gd/Gf/Gr and Gs interfaces. The solution provides a completely scalable solution and for the Gb Interface, enables a large number of BSSs to be connected to a single SGSN. Multiple cards can support up to 2,048 Frame Relay channels and thousands of DLCIs per system. For maximum performance of the application, the HDC-PMC card enables an OS independent solution.
