FEATURES

• Allows async multipoint polling over frame relay networks
• Async RS-232 interface up to 57.6
• Sync RS-232 composite to 128 kbps
• Use for financial, traffic, SCADA networks
• Internal DSU option
• Simple to configure for polling protocol and address mapping
• Often more cost effective than multipoint polling modem networks

The BPF is easily configured. A host BPF port is simply mapped to the remote DLCIs that will receive the host polling data. No knowledge of the systems internal polling protocols is required.

The BPF makes it easy to convert async polling networks from multi-point modems to frame relay. Fast polling modems are disappearing from the market place at the same time async polling systems are requiring more bandwidth as their requirements move from 1200 to 9600 bps and faster. As remote terminal units become more capable, more data must be exchanged from the host to the remote units for financial, traffic and SCADA networks. The BPF is the ideal product for this requirement. It supports async port speeds up to 57.6 Kbps and synchronous frame relay composite speeds to 128 Kbps.

The BPF is often more cost effective than analog high speed fast polling modems. Frame relay networks are becoming less expensive than analog multipoint networks, and the DSUs are less expensive than high speed fast poll modems, even in combination with DCBs SR-BPF. The hardware cost savings alone provide a compelling reason to use the BPF.

An internal DSU is also available for the BPF, as well as for the remote units, which are the DCB SR-01-BPF frame relay units. With an internal DSU, you get the entire package in a single enclosure.

SPECIFICATIONS

• Rates: Async port to 57.6 Kbps (57.6 default)
• Application: Frame relay point to multipoint for async polling protocols. The SR-01-BPF frame relay unit is used at the remote end in conjunction with the BPF master. Remotes requiring more than one port use the SR-04-BPF hardware.
• Composite and async ports are RS-232
• Supports frame relay composites to 128 Kbps
• Up to 40 DLCIs may be mapped to each host port
