Sangoma A400 FXO FXS Analogue PCI Card

Please Note: This is a PCI Card. Please make sure your motherboard/server is compatible with this product.

The A400 Series is the high density version of the popular A200 series analog cards. Identical in operation and configuration, and using the same FXO and FXS modules, the A400 system supports twelve ports per main board and REMORA, as compared to four ports for the A200.

If you need to, one additional REMORA card can be added to the base twelve port A400 card. A single PCI or PCI Express slot host connection can support up to 24 FXO/FXS ports with common synchronous clocking for all channels.

Supporting the same total capacity of the A200, the A400 is designedfor those specific requirements, where the space might not be availablein the PBX case to have upto 5 additional Remora's like the A200, but the same large capacity is still required.

Like all the Sangoma AFT Series, the A400 and REMORA system has field upgradeable firmware to take advantage of enhancements as they become available. Optionally, the A400 supports Sangoma's echo cancellation and voice enhancement DSP daughterboard for carrier grade echo cancellation and voice enhancement.


The A400 consists of an A400 REMORA daughterboard mounted on the AFT PCI /PCI Express. The A400 REMORA card has six 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 one additional A400 REMORA daughterboard can be mounted in empty slot positions beside the A400 assembly, connected to the A400 by a backplane bus connector. Each 12 port A400 REMORA card is connected by means of a standard 12 line color coded telephone cable terminating at the card in a robust DB25 connector, and ready for hard wiring into a punch block at for the PSTN connection.
