Sangoma A200 Remora Slave Card - 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 Sangoma A200 card supports upto 5 slave cards, providing 24 ports (12 modules).

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.
