Adax HDC3-EM SS7 Signaling Controller for PCIe ExpressModule

Adax introduced the HDC3 SS7 signaling controller for the PCIe ExpressModule (PCIe EM) format. The Adax HDC3-EM enables the HDC3 SS7 signaling board to be used in systems using the new PCIe EM architecture, such as the Sun Blade 6000 servers. The HDC3-EM is designed to meet the PCISIG PCI Express ExpressModule Specification Revision 1.0. The Adax HDC3 family is also available in PMC, AMC, PCI/X and PCIe (full height and low-profile) board formats, all of which share a common software driver and have a consistent API for application portability.

The Adax HDC3 board is a flexible and scalable I/O solution. The HDC3-EM has four or eight E1/T1 ports and two Ethernet interfaces which enable both SS7 and SIGTRAN to run on a single card. Delivering up to 248 MTP2 links or eight HSLs (Q.703 Annex A or ATM AAL5) per card, the HDC3-EM board is able to perform many thousands of transactions per second, placing minimal load on the host, maximizing application performance and ensuring no degradation of service for the customer.

Adax HDC3 Features

  • 8 software selectable trunks of full E1, T1, or J1 per card
