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.
The handsets used with the RWIU system have many of the same Strata DK Digital Telephone (DKT) features. Unique Electronic Serial Numbers (ESNs) are programmed into the handsets at the factory and are automatically configured the first time a call is made. Strata AirLink Installation Guide 5/00...

Pre-installation This chapter provides common step-by-step pre-installation procedures and several sample configurations for both Strata AirLink Wireless systems. The configurations range from a single system with one or two Base Stations to multiple-overlapping systems. The anticipated coverage of 320,000 square feet per Base Station and a maximum number of 32 users for each system was used to layout the samples.
