PCI Type: PCI Express

Sangoma's A200 4 port FXO/FXS card delivers superior audio qualities and is expandable to 24 ports in a 2U form factor, with optional carrier-grade echo cancellation.

As you need them, additional REMORA cards can be added to the base four port A200 card. A single PCI slot hosts connection for up to 24 ports and ensures common synchronous clocking for all channels.

The A200 AFT architecture is shared with Sangoma's A101, A102, A104 and A108 cards ensuring common 3.3v/5v, high performance and universal PCI compatibility.

Like all the Sangoma AFT Series, the A200 and REMORA system has field upgradeable firmware to take advantage of enhancements as they become available. Optionally, the A200 supports Sangoma's echo cancellation and voice enhancement DSP daughterboard for carrier grade echo cancellation and voice enhancement.

Architecture

The A200 consists of a REMORA daughterboard mounted on the AFT PCI card. The REMORA card has two sockets each which can accept an FXO-2 or FXS-2 module. Each FXO-2 or FXS-2 module supports two FXO or FXS lines respectively.

Up to five additional REMORA daughterboards can be mounted in empty slot positions beside the A200 assembly, connected to the A200 by a backplane bus connector.

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 provides a kit of 12 RJ11/4 plugs and a crimping tool.
