Adax HDC3

8 Trunk SS7 Signaling & I-TDM Controller

Compatible Operating Systems: Linux, MontaVista CGE, Solaris X.86 and Solaris SPARC as standard. Other OS support on request.
Specification Compliance: PICMG AMC.0, PICMG AMC.1, PICMG AMC.2, PICMG AMC.3, IPMI

The HDC3 is the 3rd generation of the highly successful Adax SS7 controller and offers up to 8 T1, E1 or J1 trunks per card. Specifically designed to meet the demands of wireline, wireless and convergence platforms, the HDC3 excels at traditional TDM SS7, High-Speed ATM SS7 as well as I-TDM voice interworking. The HDC3 provides a high density,high performance solution for signaling and interworking applications.

Delivering up to 248 LSL MTP2 links, I-TDM flows or 8 HSLs per card, the HDC3 provides one of the highest densities on the market today, making it ideal for demanding telecommunications applications with high capacity and throughput requirements. The low-power on board processor performs many thousands of transactions per second, with minimal load on the host, maximizing the performance of the applications and reducing system costs without compromising reliability.

The HDC3 is available in PMC, AMC, PCI and PCIe (including the new ExpressModule) form factors, all of which share a common software driver and have a consistent API for application portability. This makes the HDC3 card a highly flexible, scalable and portable signaling solution for all system architectures that maximizes protection of investment.
