Aculab has launched a 30-channel IP telephony gateway PCI card.

Complementing its highly successful existing 60 channel IP telephony gateway PCI card, which also supports G.711, G.723.1 and G.729 (A and B) codecs, the new card is available with an optional E1/T1 trunk module, making it suitable for all implementation opportunities.

The card can also be supplied as an Ethernet only option, useful for IVR systems connected directly into packet networks.

Key benefits of the new gateway include ease of use through a simple familiar application programme interface (API), optimal use of channels and fully specified performance characteristics.

Multiple cards can also be installed in the same system to build a single large gateway.

According to Malcolm Campbell, Aculab's IP technology team leader, Aculab's technology has been designed to minimise factors that impact conversation quality including delay, echo and background noise.

"This leads to reduced 'effort to listen' as far as users are concerned", he says.

Aculab's IP telephony gateway is designed as a multiple class terminal to meet TIPHON quality of service (QoS) ratings.

"There are five ratings for QoS which are Best, High, Medium, Acceptable and Best Effort", explains Malcolm Campbell.

"A system using Aculab's card allows Best quality ratings to be achieved on a suitable LAN and High quality ratings to be achieved on a suitable WAN".
