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 resource.

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 Generic Requirements
