What is Remote Bridge?

A bridge that connects two geographically separated networks by using a telecommunications service such as Plain Old Telephone Service (POTS), leased lines, or a circuit-switched service.

A remote bridge has at least one local area network (LAN) port, such as an RJ-45 jack for an unshielded twisted-pair (UTP) LAN connection to a switch or a hub, and at least one serial port, such as an RS-232 port or V.35 interface. The serial port is synchronous for digital lines or asynchronous for modems.

The bridge might have both synchronous and asynchronous serial ports. Remote bridges can also be enabled for Simple Network Management Protocol (SNMP) and have other diagnostic and support features such as out-of-band management (OBM) support.

TIP

To use remote bridges to connect remote LANs, connect a bridge to the main hub or switch in each LAN, and then connect the serial port on each bridge to the modem, Integrated Services Digital Network (ISDN) terminal adapter, or Channel Service Unit/Data Service Unit (CSU/DSU), depending on the type of wide area network (WAN) link used.
