scope:
This European Telecommunication Standard (ETS) specifies the minimum performance characteristic and the related methods of measurement for on-site paging transmitters and receivers. Although this ETS covers the general operational aspects of on-site paging systems, it is restricted to the wireless (radio and loop) communications of the service. It is assumed that the radio type of system will operate in the frequency range of 25 MHz to 470 MHz, and loop systems below 146 kHz.
This ETS does not cover radiation below 25 MHz, except for the output of loop equipment.
This ETS does not include performance characteristics that may be required by the user or requirements for interfacing equipment.
Additional standards or specifications may be required for equipment intended to interface to the Public Switched Telephone Network (PSTN).
This ETS also contains instructions for the presentation of equipment for type testing purposes.
The types of equipment covered by this ETS are as follows:
- base station transmitters (radio and loop) and transcoders, with or without an external 50 Ω antenna connector;
- base station receivers, with a permanent 50 W connector;
- pocket unit (receiver, transceiver or transmitter), with or without an external 50 Ω antenna connector.
