Sangoma Remora A20101 PCI Card with 2FXS and 2FXO Ports The A200 and REMORA system together comprise the FXO/FXS version of Sangoma's range of Advanced, Flexible Telecommunications (AFT) hardware designed for optimum support of analog voice traffic. Sangoma Remora A200 Series - Model A20101 PCI - Analog Dual FXS, Dual FXO The A200 and REMORA cards support up to a total of 24 FXO and/or FXS connections. A single PCI slot host connection for all ports ensures common synchronous clocking for all channels. The base AFT architecture is shared with Sangoma's A101, A200 and A104 cards ensuring proven 3.3v/5v, high performance PCI compatibility.  Like all the Sangoma AFT Series, the A200 and REMORA system is field upgradeable to take advantage of the hardware and software improvements as they become available. Also, the A201 supports Sangoma's echo cancellation and voice enhancement board so that hardware voice enhancement is available for analog as well as TDM voice. Architecture
The A200 consists of a REMORA daughterboard mounted on the AFT PCI card . The REMORA card has two sockets each of which can accept an FXO-2 or FXS-2 module. Each FXO-2 or FXS-2 module supports two FXO or FXS ports respectively. Up to four additional REMORA daughterboards can be mounted in empty slot positions beside the A201 assembly, connected to the A201 by a backplane bus connector.  Technical Specifications - From 2 to 24 ports supported, mixing FXO and FXS interfaces as required.
- Support for the Asterisk™, OPAL™ PBX/IVR projects, as well as other Open Source and proprietary PBX/Switch/IVR/VoIP gateway applications.
