Sangoma Enters Analog Telephony Market with Release of Remora A200 Analog Cards

March 9, 2006 by Garrett Smith

Sangoma has recently announced their A200/REMORA FXO/FXS Analog Telephony support System. It is now available at VoIPSupply.com

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.

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

Wiring Connections

The A200 and Remora cards incorporate four, 4 pin RJ11 narrow jacks such as used in telephone handsets. Each A200/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 system, Sangoma has a kit available consisting of 24 RJ11/4 plugs and a crimping tool.
