Protocol controllers take RTOS onboard
Adax has added the VxWorks real-time operating system from Wind River to the range of operating systems currently supporting Adax solutions
Using the WindNet Streams enables Adax to bring into the RTOS environment the proven, reliable and high performance Streams-based architecture of its ATM and HDC high-density channellised protocol controllers. This is a huge benefit to designers of 3G and VoIP networks. Two features of VxWorks RTOS make it particularly suitable for 3G applications.

Protocol acceleration board boosts performance
Adax has launched the SDCIII AMC, a protocol acceleration board designed to enhance IP network performance by offering packet processing, IP security and signaling capabilities
First, VxWorks supports priority pre-emption scheduling and fast task context switching.
These are important for real-time video and voice processing where delays in packet delivery can seriously affect QoS.
Secondly, the flexibility and scalability provided by VxWorks mean that developers can choose from numerous programming options to create configurations that meet their requirements.

They can also choose to allocate scarce memory resources to their application, rather than to the operating system.
"The decision to provide VxWorks RTOS for Adax's HDC and ATM protocol controllers is in line with Adax's commitment to provide our customers with competitive advantages in the migration to 3G and VoIP networks", said Robin Kent, Director, European Operations for Adax Europe.
"This development combines performance with robust, reliable products".
In the three years since HDC and the ATM protocol controllers made their debut, the Adax product development team has constantly added new features and advanced capabilities to the boards, allowing them to maintain industry-leading performance.
With Adax SCTP/T for reliable packet delivery over IP networks, AAL2 for voice and video and AAL5 for signalling and IP over ATM, and Classical IP over ATM, Adax HDC and ATM controllers are ideal foundation blocks for SGSN, RNC, Node B, GGSN and softswitches, or ATM and frame relay switches.
The boards are available in PCI, cPCI or PMC form factors.
The two Adax protocol controllers complement each other with the HDC providing a powerful narrowband and broadband MTP-2 signalling solution and the ATM, its broadband counterpart.
High-speed access to wireless sites, PSTN, VPN and IP networks is provided through T1, E1, OC3 or Ethernet connections.
The established Adax protocol software product line of SCTP/T, MTP-2, Frame Relay, LAPB/D/V5, SSCOP/SSCF-NNI over ATM or IP, as well as support for Sigtran's M3UA, SUA, M2UA, M2PA and other user adaptation layers are also available on the two protocol controllers.
