Central Office/Network Environment Equipment Installation/Removal Generic Requirements
Document Number GR-1275
Issue Number 12
Issue Date Dec 2010
Replaces TR-NWT-001275 Issue01
ABSTRACT: GR-1275 provides a broad coverage of the generic requirements associated with the support that Installation Suppliers or their
sub-contractors are expected to provide with their products, features, or services. These services might be associated with the
installation of new or expanded equipment, and the removal of existing equipment.
GR-1275 addresses the installation and removal of equipment in "both" traditional Central Office (CO) and emerging-technology
equipment environments operated by Telecommunications Carriers (TCs). These equipment environments warrant installation quality
requirements that are consistent with established practices, while facilitating the adoption of new technology. For over 15 years, the
Engineering and Installation Technical Advisory Group's (EI/TAG's) proven set of GR-1275 requirements has been a valued industry
In addition to an extensive review of the document, the most significant change in Issue 12 is the assignment of defect weightings
to the requirements. These defect weightings are designed to assist Auditors and Quality Assurance Inspectors who perform inspections
and assessments of the Installation Supplier's completed work in a Central Office (CO) environment. Weightings dictate the time
allowed for corrective action. Critical weightings require immediate action.
This reissue also includes:
- New and revised requirements in the areas of safety, auxiliary framing, cabinets, cabling and wiring, connecting, equipment
designations, power, bonding and grounding, equipment removal and cable mining, fiber optic, building requirements, fire-stopping, and
assessment of Installers' skill levels, etc.
- New and revised criteria, tables, and figures
- Further harmonization with its companion document, GR-1502-CORE, Central Office/Network Environment Detail Engineering
GR-1275 should be used in conjunction with GR-1502 for equipment installation and detail engineering. Buy FR-INSTALL-19 and
receive both GRs, plus GR-2981, Quality Program Analysis (QPA) for Telecommunications Engineering or Installation
Suppliers, at 30% off the total price.
