Dialogic Blue OneSpan Single PCI Express E1/T1/PRI interface, Software Echo Cancellation, Low Profile Form Factor

The Dialogic® BlueTM OneSpan-24/30-S-LP Telephony Board is an efficient one-span host-based call-processing board for the open source market, which includes features for Interactive Voice Response (IVR) along with call transfer emulation, G.711 support, automatic gain control (AGC), and software-based echo cancellation.

The form factor of the OneSpan-24/30-S-LP Telephony Board is Low Profile PCI Express (PCIe), which is half the length and half the height of a standard PCIe board. The OneSpan Board is very well suited for installations in which one or two telephony boards are needed to provide from 24 to 60 channels (phone line connections) for a single server.

The OneSpan-24/30-S-LP Telephony Board supports features required for most communications applications and for use in many Asterisk environments. Because it supports many standard APIs, the OneSpan Board is very useful when developing new applications.

The OneSpan-24/30-S-LP Telephony Board is supported under the Linux operating system.

• Brings Dialogic® technology to the Asterisk market
• Easy to install and operate
• Facilitates upgrading to a more powerful Diva Media Board for increased scalability or extended feature set

The OneSpan-24/30-S-LP Telephony Board supports features required for most communications applications and for use in many Asterisk environments. Because it supports many standard APIs, the OneSpan Board is very useful when developing new applications.The OneSpan-24/30-S-LP Telephony Board is supported under the Linux operating system. Support for Windows® is planned for Q4 2010.

Choosing a Host Processor

Because it is a “passive” board without an onboard CPU or DSPs, the OneSpan-24/30-S-LP Telephony Board relies on the host CPU to provide the computing power for the functionality that an application requires, such as echo cancellation and line interconnect. For this reason, the host CPU must be carefully selected to provide an appropriate feature set and system load capabilities. A system with 3MB L3 cache and 2.26GHz processor speed and 4 GB of DDR3 memory, for example, should be sufficient for many applications. Generally the OneSpan-24/30-S-LP Telephony Board is suitable for applications such as IVR systems designed to handle a maximum of 50 calls simultaneously, low-density conferencing servers with a maximum of six attendees, monitoring applications (two One Span Boards are required), and other telephony applications that use only a moderate amount of host resources. Applications such as large conferencing servers with echo cancellation normally require a more powerful system and possibly more powerful telephony boards.
