Equipment Physical Design Standards ATT-TP-76200, Issue 19

AT&T Services, Inc. June 2014

Unless otherwise detailed in this document or instructed by AT&T, Level Three is the

applicable level for all network equipment.

Equipment Types

Carrier Grade Equipment (CG) – Equipment designed and verified for high reliability

and/or safety use in Carrier Communications Spaces. See ESR-CG Level 1 and 3.

Non-Carrier Grade Equipment (NCG) – Equipment designed and verified to meet

common commercial grade safety and reliability requirements. See ESR-NCG Level 1

and 3.

Network Administrative Support Equipment - Administrative network support

equipment (e.g., computers, monitors, telephones, etc.) located in any network

equipment space shall meet Non-Carrier Grade (NCG) Level 1 safety requirements.

Outside Plant (OSP/CELL-SITE) Equipment *– CG equipment designed and verified to

meet hardened environmental requirements. There are four levels of OSP/CELL-SITE

equipment:

• OSP/CELL-SITE Class 1 - Controlled Protected Environments refers to an internal

environment typical to Huts and CEVs, per GR-3108-CORE

• OSP/CELL-SITE Class 2 - (-40C to +65C) Protected Equipment in Outside Environments

refers to an internal environment typical to GR-487 compliant remote cabinets, per GR-3108-

CORE

• OSP/CELL-SITE Class 3 - (-40C to +70C) Protected Equipment in Severe Outside

Environments refers to an internal environment typical of GR-487 non-compliant remote

cabinets, per GR-3108-CORE.

• OSP/CELL-SITE Class 4 - Unprotected Environments Directly Exposed to Weather refers

to an open, unprotected environment such as ONTs, and active NIDs (iNIDs), etc where the

equipment electronics are an integral part of the enclosure

Specific requirements for OSP/CELL-SITE electronic equipment are embedded in each

section of this document and summarized in Forms ESR-001-OSP/CELL-SITE and 003-

OSP/CELL-SITE.

*Per Telcordia GR-3171, Generic Requirements for Network Elements Used in Wireless

Networks Physical Layer Criteria, equipment deployed in an outside wireless network shall meet

the same requirements as equipment deployed in wire line outside environments.
