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

AT&T Services, Inc. June 2014

i. Manufacturer shall enter the respective airflow path(s) in the space

provided adjacent to the Yes or No indicator on Form ESP-001/2.

ii. Where more than one path exists, separate each path with a comma (e.g.,

F1-R3, F2-R3).

iii. Other cooling methods shall be explained with a statement included as

attachment to Form ESP-001/002.

Figure 6.4 - ESP – Path Designations

c. ESP Form - Non-Standard Airflow Path Reporting

Equipment cooling airflow designs other than front to rear/top (or BXT for

OSP) are considered non-preferred (e.g., side flow, etc.).

i. Equipment with non-preferred air flow path(s) will no longer be considered

for approval unless submitted with an integrated / attached air flow

redirection solution which effectively adjusts the air flow to the standard

front to rear requirement.

ii. Equipment with non-preferred air flow path(s) will be considered by ATT

Services; however non-preferred flow equipment will be considered on a

case by case basis and will require deployment restrictions or equipment

revisions prior to deployment.

Specifically, side to side air flow (e.g., SR2-SL2, etc.) and bottom to top

airflow (e.g., B-T) (Equipment for Mobility remote offices accepted) shall

require air deflection units as part of the equipment deployment to affect

the change of air flow to front to rear.)

2. ATIS Table 2 Airflow Reporting - General

The ATIS Table 2 Airflow Measurements source information is found in the

same ATIS document (ATIS- 0600010.03.2011 Heat Dissipation

Requirements for Network Telecommunications Equipment) described in

Section 6.4.E above.
