cPCI Central Office switch based on Linux

Axtar Limited has announced OneSwitch, the industry’s first standards-based Central Office programmable telephony switch to use Linux and the compactPCI (cPCI) form factor.

Axtar Limited, a UK-based developer of programmable communications solutions for public network operators and service providers, has announced OneSwitch, the industry’s first standards-based Central Office programmable telephony switch to use both the Red Hat Linux operating system and the compactPCI (cPCI) form factor.

OneSwitch is also the first system to combine a carrier-grade programmable switch, a Voice over IP Gateway and a value-added services platform. Value-added communications services that can be supported by the OneSwitch include: web-based call centre services, personal numbering, pre-paid calling card, Internet Call Waiting services and 1xxx services.  The Axtar OneSwitch supports both circuit switched interfaces such as TDM (E1 or T1) as well as IP (Ethernet) network interfaces. It is a complete replacement for a CLASS 5 or CLASS 4 central office switch and can be implemented on its own as the primary (core) switch in a small network or as an edge switch for larger networks.

Its architecture is both signalling agnostic and bearer agnostic, meaning that high-level value-added applications are abstracted from low-level issues such as network protocols (SS7, ISDN), transmission medium type (TDM, IP) and media coding methods (G.711, G.723, G,729).

To achieve the goals of high availability and low MTTR, the OneSwitch is housed in a custom-designed compactPCI (cPCI) chassis, with dual redundant PSUs, which houses up to 12 hot-swappable cPCI resource cards (such as E1/T1, IP, DSP).

Axtar supports many open interfaces defined by the ITU, ETSI, IETF and related industry standard-setting organisations. Much of the internal architecture is based on Intelligent Network (IN) standards including CS1 and CS2.

External interfaces available for developers include a PARLAY-compliant interface, an MGCP interface, and a CS1 interface.

The product will start shipping Q3 2000.
