21 November 2002 - UK, Germany, Australia, US, South America, Korea, China, India --
At Telecom Asia 2002, Aculab, a leading provider of enabling technology for the communications market, will launch its IP telephony cPCI card. For computer telephony developers and system integrators who are seeking to implement conversation quality speech over IP networks, this standards based card offers up to 120 channels with low latency using H.323 or SIP in a single slot.

Aculabs card offers the essential performance features necessary for telco grade products, plus scalability to build a single gateway with multiple cards, optimal use of channels and fully specified performance characteristics.

Ease of use is assured through a simple extension to Aculabs generic API. Alternatively, for developers seeking to employ the card as a real time protocol (RTP/RTCP) resource for use with a third party or proprietary protocol stack, for example, an additional API is available, which provides control of the card as a media gateway.

Aculabs IP telephony card has sufficient power to simultaneously handle up to 120 channels using any supported codec: G.711; G.723.1; G.729 (A&B). There is a free allocation of any of the above codecs on a per channel basis ensuring full usage at all times.

With no adverse loading to the host and minimal contribution to delay from the card, there is little impact on latency regardless of the number of cards used. Users can select the number of codec frames to be included in each RTP packet, which allows for a trade-off between bandwidth overheads and delay.

Aculabs technology has been designed to minimise factors that impact conversation quality including delay, echo and background noise. This leads to a reduced 'effort to listen for users. The IP telephony card is designed as a multiple class terminal to meet ETSI TIPHON quality of service ratings. A system using an Aculab card allows Best quality ratings to be achieved on a suitable LAN and High quality ratings to be achieved on a suitable WAN. Participation in differentiated services (diff-serv) quality of service management for networks is facilitated by API access to specify the diff-serv code point (DSCP) in the type of service (TOS) byte in the IP header. Therefore, it is possible to deploy an interoperable solution meeting high performance standards in a well-managed private network environment.

For developers seeking to provide IP telephony features in new solutions or to enhance existing applications and replicate existing functionality, Aculab has implemented several H.450.2 call transfer cases.

About Aculab
Through a customer-focused approach to development, Aculab has produced a computer telephony (CT) product portfolio that satisfies the speech resource and global digital connectivity requirements of developers and system integrators. CT applications utilising Aculabs components can handle real-time telephony, through an extensive range of resources and signalling systems.

The evolution of Aculabs generic API, to provide a consistent programming interface, reduces the integration time of a combination of technologies including text-to-speech (TTS), automatic speech recognition (ASR), conferencing and fax. Collectively through supporting a broad range of industry standards and operating systems, Aculab can provide the products needed when quality and performance cannot be compromised.

Aculabs head office is located in Milton Keynes, UK with offices in North America, Germany and Australia. Website: www.aculab.com
