• Sixteen T1/E1 ports with optimum PCI–Express interface for high performance voice and data applications
• Mix T1 channel banks and E1 networks with full channel synchronization. TDM clocking mode lets network timing to be passed from a network-connected DS0 to any or all of the other ports so both T1 and E1 are supported simultaneously
• Support for Asterisk® and FreeSwitch®
• Fully compatible with all commercially available motherboards—proper PCI-standard interrupt sharing without manual tuning
• Dimensions: Full height by half length (107mm x 176mm)
• Connector: Dense 68 pin SCSI type interface 
• Intelligent hardware: Downloadable FPGA programming with multiple operating modes; add new features related to voice and/or data when they become available
• Line decoding: HDB3, AMI, B8ZS
• Framing: CRC-4, Non CRC4, ESF, SF, D4, J1 (Japan)
• PCI Express Bus Version: 1.1
• Maximum operational power: 5.5 W (1.67 A @ 3.3 V)
• Temperature range: 0 – 50 °C
• Ring buffer DMA handling for minimum host intervention and guaranteed data integrity on high volume systems
• Supports Robbed Bit Channel Associated Signaling (CAS) and ISDN PRI
• T1/E1 and fractional T1/E1, multiple channel HDLC per line for mixed data/TDM voice applications
• Optimized per channel DMA streams and hardware-level HDLC handling unload the host CPU
• Uses raw bitstream interfaces to support arbitrary non-standard line protocols, such as non-byte aligned monosynch or bisynch
• WANPIPE® routing stack is completely independent of TDM voice application for total system reliability
• WANPIPE® supports certified, field-tested, and reliable Frame Relay, PPP, HDLC, and X.25

Optional DSP Hardware Echo Canceller Daughterboard

• G.168–2002 echo cancellation in hardware
• 1024 taps/128 ms tail per channel on all channel densities
• DTMF decoding and tone recognition
• Voice quality enhancement: music protection, acoustic echo control, and adaptive noise reduction
• Does not increase the physical size of the card, and no additional slot is required

Operating Systems

• Windows® 2003, Windows® XP, Windows® Server 2008, Windows® Vista, Windows® 7
• Linux (all versions, releases and distributions from 1.0 up)

T1/E1 Status Alarms

• RED: Telco Red Alarm Condition
• OOF: Out of Frame
• LOS: Receive Loss of Signal
• AIS: Alarm Indication Signal
• RAI: Remote Alarm Indication (Yellow Alarm)
