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.

GR-1502 is a companion document to GR-1275.

Issue 8:

• Revised many of the auxiliary framing and support criteria to reflect
  common practices in earthquake zones 3 and 4


• Extensive revision of figures, particularly in Sections 10, 13, 14, and 17,
  to improve clarity and readability, and to more accurately illustrate the
  criteria


• Revised criteria in Section 21 to provide correct terminology


• Provides additional guidelines and criteria for vertical space planning


• Changes to help harmonize the criteria of GR-1502 with those of
  GR-1275.

When using GR-1502, you may need to refer to GR-63, GR-295,
GR-347, GR-356, GR-383, GR-449, GR-1089, GR-1275,
FR-64, FR-440, FR-2063, FR-INSTALL-19, and various standards
documents.
