RB-DS.11 Wireless Bridge

The RB-DS.11 Wireless Bridge connects a remote Ethernet network to a central

network server or Internet site via a BU-DS.11 Multipoint Base Unit.

The maximum number of MAC addresses that the unit can handle at any specific

time is 1024 and the Aging algorithm is applied at all times.

When a station on the Ethernet LAN sends a message that is not destined for a

local station, the RB-DS.11 forwards the message to the BU-DS.11. When the

BU-DS.11 receives a message destined for a station on the RB-DS.11's LAN, the

BU-DS.11 forwards it to the RB-DS.11. In this manner, the RB-DS.11 and the

BU-DS.11 work together like a standard network bridge.

The first time each station on the RB-DS.11’s LAN sends a message, the station’s

address is registered by both the RB-DS.11 and the BU-DS.11. It is possible for the

RB-DS.11 and BU-DS.11 to store all the addresses necessary to support an entire

LAN connected to a RB-DS.11.

The RB-DS.11 comes in two options: The RB-DS.11 and the RB-DS.11D.

The RB-DS.11 is the basic unit, equipped with an antenna integrated into the front

cover of the outdoor unit.

The RB-DS.11D has no integral antenna and is equipped with an antenna

connector (on the outdoor unit) for the connection of an external antenna (not

included with the unit).

Refer to Antennas for Outdoor Applications on page 2-6 and Available Antennas on

page 2-7 for information on how to select an external antenna.
