ABSTRACT: GR-1293-CORE contains requirements for standby engine-generator systems including fuel cells to be used in remote telecommunications
sites. Such sites have the following characteristics:
They are small sites, both in terms of physical size and power requirements.
They contain telecommunications equipment in a location outside the traditional telephone Central Office (CO) (wireline or
Typically, they physically resemble existing applications in Electronic Equipment Enclosures (EEEs) and Controlled Environment
On-site, permanently installed, i.e., dedicated, standby backup generator systems are one alternative to long battery reserve times.
The scope of this document therefore includes generic requirements for small, dedicated backup generators equipped for automatic
starting and load transfer. GR-1293 is not intended to cover all application considerations and generic requirements for the connection
and use of portable engine-generators. End-point requirements for backup generator systems having direct current, as well as or in lieu
of alternating current outputs, are included.
