Specifications:

Eight T1/E1 ports with a single PCI interface for high performance voice and data applications.
TDM clocking mode: Network timing can be passed from a network-connected DS0 to any or all of the other ports. Both T1 and E1 are supported Simultaneously, making it possible to mix T1 channel banks and E1 networks with full channel synchronization.
Line decoding: HDB3, AMI, B8ZS. Framing: CRC4, no-CRC4, ESF, D4T1/E1.
Support for the Asterisk ™, OPAL ™ Yate, FreeSWITCH ™ PBX / IVR projects, as well as other Open Source and proprietary PBX / Switch / IVR / VoIP gateway applications.
