Base Stations - Toshiba Strata DK14 General Description Manual

Base Station Interface Adapter (BSIA)
The BSIA interfaces the wireless system to the office telephone system. It supports up to two Base
Stations and is designed for wall or rack mounting. Information stored in the BSIA assigns
handsets to Base Stations and defines the handset feature operation.
The BSIA sends information about system operation and alarm conditions to a PC using its RS-
232-C port and the Strata AirLink Manager software.
RWIU Interface Unit
The RWIU PCB functions as a protocol converter between the Base Stations on one side and the
Strata DK system on the other. The RWIU is the "master" PCB, generating timing and
synchronization signals and the WWIS PCB is the "slave." The WWIS has four Base Station
interface connectors. The PCBs have LEDs that indicate a continuous status of operation for both.

Base Stations

Base Stations (shown in
radio transmitters and receivers that
handle communication with the handsets.
The Base Stations relay calls between the
handsets and other telephones and trunks
connected to the office telephone system.
LEDs on the Base Station provide
diagnostic information for System
Administrators.
Each Base Station provides coverage for a
particular area and supports eight
simultaneous conversations.
In typical office environments, each Base
Station, using four antennas for the best possible signal reception, has a broadcast range of up to
328 feet and supports an area of 320,000 square feet. To increase traffic capacity without
interference, the Base Stations can be placed in the same coverage area (co-location).
Wireless Test Stand
The Strata AirLink Wireless Test Stand easily determines proper Base Station positioning prior to
permanent installation. The test stand is mobile, enabling quick identification of the best possible
locations for each Base Station. It generates set frequencies for the handset to lock onto and
verifies Bit Error Rate (BER) status.
Strata AirLink BSIA Manager Software
The Strata AirLink BSIA Manager software is a Windows 95 application that includes:
Easy-to-use Desktop Toolbar for navigation
Configuration Window for setting system parameters and handset features
Status Window to view system alarms
Upgrade icon for immediate upgrades to the BSIA and Base Stations
