qbridge

qBRIDGE is a family of high performance access devices (modems/ converters) operating in the "Bridge connection" mode which prime function is connecting remote segments of Ethernet 10/100Base-TX networks. Various data transfer techniques via copper or optic channels are applied.

The device encapsulates LAN (Ehternet) data packages to a WAN (HDLC) synchronous port and vice versa. Maximum data transfer and filtration speed is 90000 packages per second with the size of adjustable package buffer as much as 340 frames. WAN can use any synchronous serial interface with 50 Mbps max speed from among already implemented or on the base of the customer order. The "Bridge connection" mode provides transparency for any protocol (TCP/IP, IPX, etc) as well as "standard" and "long" VLAN frames transfer.

""Point-to-ponit" technique can be applied to all qBRIDGE modifications when remote LAN segments are connected. Some qBRIDGE modifications can be used for "point-multipoint" systems, when for example Internet connection is required.

Various modifications with different WAN-port interface are produced in this series:
