SCxbus Adapter
Internode Connectivity Solution

Features:

• Enables developers to take full advantage of the 1024 bi-directional time slots of the SCbus by spreading the application across multiple PCs (nodes)
• Static custom configuration program available for blocking time slots and increasing total system bandwidth to 4,096 time slots across multiple PCs (nodes)
• Switchless design takes advantage of the inherent switching capabilities of the SCbus
• Connect up to 16 nodes within a 15 meter distance
• Fault tolerant clocking
• Background diagnostics continually monitor clock, frame, and data integrity-faults are immediately reported to application
• "Hot plugability" means that a node can be removed from the SCxbus without corrupting live traffic nor disturbing the entire system
• Unique message channel permits run-time control via direct, node-to-node messaging (future)
• Multiple SCxbus Adapters can be installed in a node for connection to the same or different external SCxbus--permits application to switch to redundant backup in the event of adapter or connection failure (future)

Applications:

• Call center
• Telemarketing
• Voice/audio response systems
• Predictive dialer
• Automated call rerouting applications (debit card, international callback, long distance resale)
• Wireless gateway
• Programmable switches
• Audiotex
• Operator services
• Test equipment
• Protocol conversion equipment

The SCxbus Adapter from Dialogic is a simple, economical solution for the SCSA Multi-Node Architecture (MNA). The SCxbus Adapter extends the SCbus into other nodes by providing direct signal conversion between the SCbus' TTL signals and the SCxbus' SCSI-III-style RS485 signals. A switchless design is used where each node is mapped to a desired number of physical data streams, each of which carries a fixed, 64 time slots using TDM. This permits 1,024 full-duplex devices to have complete nonblocked, internode communications while maintaining a simple, single-stage switching model.
