Sangoma A200-X

The A200-X and REMORA system together comprise the PCI-Express FXO/FXS version of Sangoma's range of Advanced, Flexible Telecommunications (AFT) hardware designed for optimum support of analog voice traffic.

The A200-X and REMORA cards support up to a total of 24 FXO and/or FXS connections. A single PCI-Express slot host connection for all ports ensures common synchronous clocking for all channels.

Like all the Sangoma AFT Series, the A200-X and REMORA system is field upgradeable to take advantage of the hardware and software improvements as they become available. Also, the A200-X supports Sangoma's echo cancellation and voice enhancement board so that hardware voice enhancement is available for analog as well as TDM voice.

The A200-X 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 A200-X assembly, connected to the A200-X by a backplane bus connector.

The A200-X and Remora cards incorporate four, 4 pin RJ11 narrow jacks such as used in telephone handsets. Each A200-X/Remora is shipped with four 2M cables terminating in a narrow RJ11/4 plug at one end and a telephone-standard RJ11/6 plug at the other. For those who need to hard wire the A200-X system, Sangoma has a kit available consisting of 24 RJ11/4 plugs and a crimping tool.
