Central Office/Network Environment Detail Engineering Generic Requirements
Document Number GR-1502
Issue Number 09
Issue Date Dec 2010
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
- 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.
GR-1502 should be used in conjunction with GR-1275 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.
