ABSTRACT: The Central Office (CO) environment is an engineering challenge, and detail engineering service providers require an established, well-considered, and proven set of Generic Requirement documents (GRs).

This document provides the Telcordia view of proposed engineering generic requirements that Detail Engineering Service Providers (DESPs) are expected to provide with their services. Adherence to these generic requirements is necessary to help ensure that newly installed equipment operates in accordance with design parameters in owned or leased telecommunications equipment buildings of the Telecommunications Carrier (TC), and to ensure that equipment is installed in a safe and efficient manner. These proposed engineering and documentation generic requirements are the criteria to which DESPs may be compared for job acceptance purposes.

The proposed generic engineering requirements contained in this document are intended to be applicable to all types of engineered telecommunications equipment, i.e., switching, transmission, and common systems; and include frame, circuit-protection devices, and power, etc. However, this document is not all-inclusive; additional engineering guidance may be required to engineer a specific piece of equipment, or to meet additional regional practices or requirements.

This GR provides requirements for the generation of detail engineering output to the purchaser and installation supplier of telecommunications equipment. It is an industry-recognized document on the Detail Engineering process, and reflects the latest developments from industry.

GR-1502 addresses the detail engineering of equipment in both traditional Central Office (CO) and emerging technology equipment environments operated by Telecommunications Carriers. Emerging technology network environments warrant detail quality requirements that are consistent with established practices, while facilitating the adoption of new technology.

GR-1502 is a companion document to GR-1275, Central Office/Network Environment Equipment Installation/Removal Generic Requirements.

Issue 9:

• Further harmonizes the requirements, figures, and tables with GR-1275
• Contains new and revised material in the areas of power, equipment layout, grounding, cable rack, auxiliary framing, lighting, outlets and raceway, wire and cable, and Central Office equipment building environment.
