Protocol Controller ATM cPCI / PCI

The Adax ATM card is the perfect solution for the rapidly evolving telecoms wireless infrastructure market to 3G and beyond, where broadband signaling and higher bandwidth is needed. For example, the narrowband/broadband signaling product combination is the ideal foundation for the GGSNs and SGSNs required for GPRS systems. The ATM virtual channels provide higher bandwidth than the DS0's used with T1 or E1 connections. The SSCF/SSCOP NNI software, the ATM equivalent to MTP-2, makes more efficient use of link bandwidth. For example a single ATM board has the potential to carry voice and data channels for hundreds of wireless users in VCI/VPIs on the same OC3 link to the Base Tranceiver Station that is carrying the signaling data.

The ATM card is a dual port, clear channel, Asynchronous Transfer Mode controller for the CompactPCI and PCI bus. It compliments the established Adax Protocol Controller (APC) product line and enables integrators and OEMs to build high performance, complex systems with any mix of ATM, Frame Relay, X.25 and SS7 from one to 64 ports and this narrowband/broadband signaling product combination is ideal for the GGSNs and SGSNs required for GPRS systems, 3G networks and beyond.
