2. Connect the 25-pair cable to the corresponding plug on the backplane. See
the “Procedure: Installing the Wireless Fixed Base”
and “Inside Wiring
Cable” sections later in this chapter for details regarding cable and power
configurations.
Wireless Fixed Base
The WFB is a radio base station. The WFB provides the radio functions necessary
to transform the following:
■ Incoming calls from the DEFINITY ECS into radio signals for transmission
through the air to the appropriate WTs
■ Incoming radio signals from the WTs into signals for transmission to the
DEFINITY ECS
Each WFB is connected to the following:
■ RC via a Category 3 twisted-pair using an Avaya proprietary interface
■ One to four CAUs via a fixed-length coaxial cable with an Avaya proprietary
interface. The fixed-length coaxial cable of a designated length is provided
and installed by Avaya only.
A WFB can support a maximum of four (remote) attached CAUs. As an
alternative, a WFB can support an internal antenna via special order. The number
of simultaneous calls that can be supported by a WFB with multiple CAUs is 12
minus the number of idle CAUs. In other words, for the WFB to carry 12 calls,
each CAU must carry at least one of the calls. However, in high-traffic areas, a
WFB is usually connected to just one CAU, which can carry 12 simultaneous
calls.
WFBs must be located throughout the interior of a premise in a manner that
ensures appropriate radio coverage. Placement of each WFB and CAU, as with
all other components, is based on the information provided by the Installation
Map. The following figure provides an illustration of the WFB.
