Versions are available for 11 bit word protocols, Racal Redac, and other protocols. Another special firmware version provides for automatic private line or dial line backup. If the frame relay link is lost, the remote BPF will automatically check the private line port and the dial up port to establish a backup link. When the frame relay link is re-established, the BPF automatically drops the dial backup link and reverts to frame relay again. Click here for a data sheet on how the backup operates.
Standard firmware allows for redundant hosts, even at different locations.
And, with an internal DSU, you get the entire package in a single enclosure. Frame relay point to multipoint for async polling protocols. The BPF-04 can duplicate a DLCI on different ports, allowing it to be used as a sharing unit at remote locations. Up to 40 DLCI's can be configured per BPF port. BPF-BU firmware is available for dial or private line backup and requires a DCB ASU at the host.
