Product Part Number:
257L119 4-Span T1 Interface Board
257L120 8-Span T1 Interface Board
PC Form Factor: Full Length PCI
TDM Bus Type: H.100
Digital Line Interface: Primary Rate ISDN / T1 Spans
The XDS 4-span and 8-span T1/PRI boards offer a 100ohm T1 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. D4 and ESF signaling are supported for T1 interfaces. Primary Rate ISDN is supported, including access to either layer 2 or layer 3 from the application level. Driver support includes Linux RedHat, Windows® 2000 / XP / NT, Gentoo, Fedora, and an Asterisk® channel driver.
T1/PRI 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 T1/PRI interface boards also include 128 ports of enhanced conferencing.
