    ABSTRACT: This document replaces TA-NWT-000026.

    GR-26 outlines the Telcordia view of generic requirements for Controlled Environment Vaults (CEVs), formerly known as Below Ground Electronic Equipment Enclosures (BG/EEE). The stated requirements are designed to provide a suitable environment for telecommunications electronic equipment that is housed in below ground, prefabricated structures.

    The possible placement of Remote Switching Units (RSUs) and other environmentally sensitive equipment necessitates upgrading the internal environment of CEVs to levels maintained within central offices. These upgraded requirements are also included.

    When using GR-26, you may need to refer to GR-27, GR-57, GR-63, GR-209, TR-NWT-001011, GR-1089, GR-1252, ANSI/ASHRAE Standard 52.1, and EOS/ESD-DS-7.1. You may also want to refer to GR-43, GR-487, and/or GR-2832.
