Description
Sangoma A102D Two-Span T1/E1/J1 PCI Card with Echo Cancellation
The Sangoma A102D supports up to 60 voice calls or 4.096 Mbps of full-duplex data throughput over two T1, E1, or J1 lines.
Take advantage of hardware and software improvements, as soon as they become available. Like all cards in Sangoma's AFT family, the Sangoma A102D is field upgradable with crash-proof firmware.
Choose the Sangoma A102D and A102DE cards with Octasic's DSP hardware and certified algorithms to achieve carrier-grade echo cancellation and Voice Quality Enhancement functions on your open source or even proprietary telephone system.
Sangoma A102D Technical Specifications
- Two T1/E1 ports
- PCI form factor
- 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, Yate, CallWeaver and FreeSWITCH PBX/IVR Projects, as well as other open source and proprietary PBX, Switch, IVR, or VoIP gateway applications.
- Dimensions: 2U Form factor: 120 mm x 55 mm for use in restricted chassis.
- Includes high-quality, tested RJ45 cables and short 2U mounting clips for installation in 2U rack-mount servers.
- Autosense compatibility with 5V and 3.3V PCI busses.
- Line decoding: HDB3, AMI, B8ZS.
- Framing: CRC-4, Non CRC4, ESF, SF, D4T1/E1. Also compatible with Japans J1.
- 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.
- 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.
