APCO has released their NPSTC Standard Channel Nomenclature for the Public Safety Interoperabilty Channels. The 2017 update provides standard nomenclature for FCC and NTIA-designated nationwide interoperability channels used for public safety voice communications. The public safety community uses spectrum allocated by the FCC and NTIA in multiple bands that is replete with interoperability channels. It is necessary to develop and employ a common set of channel names so that all responders to an incident know which channel to tune their radios to, as well as the band and primary use for the channel.
APCO American National Standards (ANS) are voluntary consensus standards. Use of any APCO standard is voluntary. This standard does not imply that there are no other guides for public safety channel nomenclature. All standards are subject to change.
To view the latest ANS for NPSTC from APCO, you can download the file from the Resources page of the NAPCO website at NAPCO.org/resources.
