XDS H.100 PCIe E1/PRA Board

Product Part Number:
259L017 : 4-Span E1 Interface Board
259L014 : 8-Span E1 Interface Board

PC Form Factor: Full Length PCIe
TDM Bus Type: H.100
Digital Line Interface: Primary Rate EuroISDN / E1 Spans


The XDS 4-span and 8-span E1/PRA boards offer a selectable 75ohm/120ohm E1 interface. Call progress tone generation and DTMF tone generation/detection are supported. Status LEDs are provided on each port for red, yellow, and blue alarm conditions. CRC4 and non-CRC4 signaling are supported for E1 interfaces. Primary Rate EuroISDN is supported, including access to either layer 2 or layer 3 from the application level. Driver support includes Linux RedHat, WindowsĂ’ 2000 / XP / NT, Gentoo, Fedora, Debian, and an AsteriskĂ’ channel driver.

E1/PRA interface boards include 128 channels of bi-directional voice resources (4-span boards) or 256 channels of voice resources (8-span boards), as well as two analog inputs for music-on-hold applications.
The 4-span E1/PRA interface boards also include 128 ports of enhanced conferencing.
