Sangoma A102DE – PCI Express

Description

The A102 is Sangoma’s next generation hardware designed for optimum support of data and voice over T1 and E1.

Sangoma A102DE Key Features

• Available as Single T1/E1 port (A101) or Dual T1/E1 port (A102) with daughterboard (as shown in photograph).
• Dimensions: 2U Form factor: 120mm x 55 mm for use in restricted chassis.
• 32 bit bus master DMA data exchanges across PCI interface at 132Mbytes/sec for minimum host processor intervention.
• Intelligent hardware: Downloadable Field Programmable Gate Array programming with multiple operating modes.

Operational modes

Data only

T1/E1 and fractional T1/E1, single channel HDLC per line. Can be used as a hub for sub-DS1 remotes. The A101c and A102c can support any configuration of up to 62 DS0s carrying Frame Relay, PPP or HDLC data. Raw bitstream interfaces can be used to support arbitrary non standard line protocols such as non-byte aligned monosynch or bisynch.

Voice modes

Supports Robbed Bit Channel Associated Signaling (CAS) and ISDN PRI. Block mode raw bit-stream interface for integration with the Asterisk Open Source PBX/IVR platform. Channelized mode supporting individual DMA into voice timeslots plus on-board HDLC support of PRI channel for soft PBX implementations that can use these features.

Mixed Voice/Data mode

Combination of router/PBX functions in one server.Both 8 bit (64kbps per channel) and 7 bit (56kbps per channel) board-level HDLC support.WAN data connection is supported by Sangoma’s standard WANPIPE® routing stack providing certified Frame Relay, PPP, HDLC and X.25. RAIV: Receive Loss of Signal YEL: Receive Telco Yellow Alarm Line protocols Voice CAS and PRI, ATM, Frame Relay, X.25, HDLC, PPP, SS7, Transparent bit-stream, BSC.
