||ANSI Approved NENA Standard
||NENA-STA-026.5-2016 (originally NENA 04-002)
This ANSI approved NENA Standard is a guide for designers and manufacturers of PSAP equipment.
It identifies engineering and technical requirements to be met before
the NENA membership shall consider purchase of such equipment; it may
also be of value to purchasers, maintainers and users of such equipment.
This document is not intended to provide complete design
specifications for a PSAP Master Clock. It will neither ensure the
quality of the performance of the equipment nor should it serve as an
exclusive procurement specification.
This standard provides a standard method of connecting an
accurate time source to the various elements of a PSAPs CPE that depend
on time information for operation. When this standard is used to guide
the design, development, and acquisition of CPE, successful system
integration of the time source equipment with the CPE elements that
depend on accurate time is enabled.
Adoption of this Standard enables interoperability among
the devices using the interfaces described. Implementation and
management of a standard time source in a PSAP is significantly improved
when products are selected that conform to this standard.
