Interface: 32 Bit PCI - 5V Lieferung ohne Treiber / Zubehör The TR114 ISDN Series multichannel Universal Port boards offers full fax and voice processing with an on-board ISDN interface. Integrated ISDN Basic Rate telephone interfaces allow direct connection to ISDN BRI telephone service. Software-controlled digital signal processors provide independent fax & voice processing on each channel.
The TR114 ISDN boards include integrated, on-board ISDN line interfaces. Integrated interfaces allow TR114 boards to be directly connected to ISDN lines and eliminate the need for separate costly ISDN-to-analog conversion devices. ISDN enables network fax applications to support inbound fax routing. ISDN lines also offer the added advantages of improved performance and reliability. The TR114 ISDN Series boards support advanced fax features including 14.4kbps transmission, MMR compression, Error Correction Mode, T.434 Binary File Transfer and Ultrafine resolution as well as high performance voice processing features such as outstanding talk-off and DTMF cut-through characteristics. The TR114 ISDN Series also offers reliable call processing integrating ISDN-reported call progress with advanced in-band call progress interpretation and reporting for ISDN-initiated calls which carry over or terminate on an analog phone network. Subscription to Direct Dialing Inwards (DDI) or Multiple Subscriber Number (MSN) services on your ISDN BRI lines allow each user on a LAN to be assigned a personal fax phone number. Upon receipt of an inbound fax call, the fax recipient's fax phone number is provided in the ISDN Called Party Number field. The Called Party Number information is then extracted by the TR114 ISDN board and passed to the fax server application allowing the received fax to be routed directly to the intended recipient more efficiently and reliably than other methods of inbound fax routing. Most network fax server applications developed for the TR114 already support inbound fax routing using Called Party Number information and will seamlessly support inbound routing with the TR114 ISDN Series boards connected directly to ISDN Basic Rate lines. The Fax and Voice Application Programming Interface (API) is a powerful tool for sophisticated application development. High-level functions permit programmers to quickly create applications. Lower level functions permit direct interactions with individual elements of fax and voice calls, such as the T.30 protocol. |
