Ideal for developers targeting applications worldwide, the E1/T1 PCIe digital network access board brings with it the entire protocol heritage you would expect from Aculab. With the widest range of protocols available, developers can confidently specify this board with 1, 2, or 4 trunks – up to 124 voice or signalling data channels. Based on the industry’s new PCI Express bus, the product provides system integrators with a durable competitive advantage for a wide range of communications solutions requiring digital network connectivity.
Networking options
When looking to select a digital network access board, planning of international product roll out should be fully considered. The E1/T1 PCIe board offers public or private network connectivity with 1, 2 or 4 trunk options. Configuration of trunks is software selectable in terms of termination impedances and for E1 or T1 presentation. Therefore, the same hardware module can be used as either an E1 or T1 trunk interface, under software control. Moreover, E1 and T1 trunks can be simultaneously supported on the same board. Benefits can be gained from the increased flexibility in deployed platform hardware, with possible reductions in system board count. Furthermore, this inherent flexibility in configuration of the E1/T1 PCIe board ensures the roll out of a truly global product. An optional tone-based signalling DSP module for interworking into legacy CAS, R2 derivatives and SS7 protocol infrastructures is also available.
For the developer
In seeking to assist developers and integrators to swiftly bring their solutions to market, Aculab has always employed a consistent API across the whole product range, so the learning curve has a low gradient. All available protocols from our portfolio are posted on our website, enabling developers to collect the software free of charge, when they need it. In case of query, our expert technical support teams are experienced and available to assist via telephone or email with no annual support fees. Additionally, Aculab offers a self help knowledge base for developers, which is accessible via our website.
Basic signal processing functions
The optional CAS/SS7 DSP module used in support of signalling in tone-based networks is capable of fulfilling some functions appropriate to a line board in non-tone-based network applications. The functionality can be downloaded under a cost free licence from Aculab’s website.
Conferencing of two parties can be achieved, with an added warn tone where there is a need to monitor a two-way conversation.
A-law and µ-law coding conversion allows incoming PCM streams in one format to be changed to the other format (with or without gain), prior to being connected to another network, or speech resource.
Tone generation and detection are required to support applications where single and dual frequency tones are needed for handshaking or navigating through user menus.
Fax tone detectionallows the application to control the routing of calls by allocating a DSP resource to ‘listen’ to each incoming channel.
