In April, Adax's SCTP implementation, SCTP/T, was tested at the IETF-SCTP bake-off in Nice, France and successfully inter-operated with other leading telco companies' SCTP offerings. In May, the Adax-Hughes M3UA- SCTP/T integrated solution was tested in Madrid, Spain and again, successfully inter-operated with those offered by other participants.

SCTP is the latest Internet Engineering Task Force (IETF) defined protocol designed to provide the same signaling quality and integrity to Internet and VPN services that we have come to know with the traditional PSTN. Adax SCTP/T not only fully meets the IETF Standards, it provides telephony profile enhancements of standard specifications in terms of heartbeat monitoring, error detection and link recovery. While error detection is 10 times faster than the Standard recommends, heartbeat intervals can be set to 60 times more frequent than is recommended.

Two other distinguishing features of Adax SCTP/T are low host-CPU usage and higher transaction rates. In the interoperability testing, while other reference systems completely utilized their host-CPU capacity, the Adax machine was usually only 5% utilized, leaving ample CPU space for the processing of upper-layer applications.

With Adax SCTP/T being deployed on our highly successful HDC and ATM cards, Adax provides powerful, flexible and fully integrated signaling solutions for Convergence networks.
