The SCX160 SCxbus Adapter introduces a hardware and software platform that forms the basis for SCSA Multi-Node Network Architecture (MNA). MNA allows you to interconnect similar or dissimilar voice processing systems to form a single distributed system image at the application level, thus breaking the single host limitation.
SCbus products or devices communicate with each other via the SCbus. All such products have one or more transmit (TX) channels and receive (RX - listen) channels. At Dialogic Service startup, each SCbus time slot is assigned to a corresponding SCxbus transmit time slot. Therefore, only a single device channel transmits on a single SCbus transmit time slot. To receive data, a device listens to the SCbus time slot connected to another device's transmit channel.
The SCX160 SCxbus Adapter incorporates a single stage, non-switching architecture. This architecture connects each data stream (bundle) of SCbus time slots on a one-to-one basis across the SCxbus so that each node can communicate with every other node by listening to each other's transmit time slot. This architecture takes advantage of the inherent switching capabilities of the SCbus. Included run-time drivers monitor operations in real-time and provide fault detection and troubleshooting functions.
The SCX160 SCxbus Adapter interfaces the SCbus transmit time slots to corresponding numbered SCxbus transmit time slots so all data transmitted on these time slots can be received at all other nodes in the system. Likewise, the SCX160 SCxbus Adapter interfaces the transmissions received from other nodes via the SCxbus to like numbered time slots on the node's internal SCbus. Therefore, any device can listen to any other device in any node by listening to the SCbus transmit time slot assigned to this other device.
