3.1 Radio exchange
The Radio Exchange (RE) interfaces between the PBX and the base stations. Incoming and outgoing
calls are routed via the radio exchange. The radio exchange is housed in a modular cabinet.
The radio exchange is connected to the PBX by standard analogue two-wire subscriber lines (one
dedicated subscriber line is required per cordless phone) and/or by a (2 Mbit/s) digital interface.
Standard RS232 ports on the cabinet make it possible to connect a personal computer and a printer
to the system. The personal computer is necessary for system initialization, system fault tracing and
system statistics information retrieval. A hardcopy of system error messages can be obtained via the
printer.
