This chapter tells you how wireless calls take place and gives you the basic system
configurations.There are two available configurations:
♦
Strata AirLink External Wireless System –
The basis for this system is the Base Station
Interface Adapter (BSIA) system that interfaces to Strata DK systems and many non-Toshiba
systems using the standard telephone ports.
♦
Strata AirLink Integrated Wireless System –
The basis for the integrated version is the
RWIU system that interfaces to Strata DK16, DK16e, DK40, DK40i, DK280, DK424 and
DK424i using a proprietary RWIU Printed Circuit Board (PCB).
Strata AirLink operates in single building and campus environments in the 1920~1930 MHz band.
This bandwidth is designated by the Federal Communication Commission (FCC) for unlicensed
operation, and an FCC license is not required to install and operate the system.
How Wireless Calls Take Place
Wireless telephone calls are similar to other calls that take place in a telephone system, except that
a Radio Frequency (RF) link is used from a Base Station.
The BSIA/RWIU and handset are assigned unique identification (ID) numbers. The handset must
have a BSIA/RWIU ID before it can communicate with a Base Station. Up to eight system IDs can
be programmed into a handset enabling operation in multiple wireless systems.
Receive Calls
The BSIA/RWIU receives a call for a specific handset and sends the call to all Base Stations. The
handset responds to the Base Station to which it is locked. The Base Station establishes an RF link
to the BSIA/RWIU, and the call proceeds like any other call.
Make Calls
When you make a call, the handset locks onto a channel on the Base Station. The Base Station
transmits the calling information to the BSIA/RWIU, and the call proceeds as any other call.
Terminate Calls
When you end a call, a signal is sent to the BSIA/RWIU freeing a voice channel and changing the
handset to standby. The BSIA/RWIU sends a release message to the Base Station and the RF link
is terminated.
