OPTI-6100 Tailored to Enable Utilities to Meet Growing Customer Demand

HUNTSVILLE, Ala. – (December 7, 2009) – ADTRAN, Inc. (NASDAQ: ADTN), a leading supplier of

next-generation networking solutions, today announced an IEEE 1613-compliant model of its

industry-leading OPTI-6100 Multi-Service Provisioning Platform (MSPP). Components of this OPTI-

6100 platform have been designed and tested to comply with the IEEE 1613 TM, "Standard

Environmental and Testing Requirements for Communications Networking Devices in Electric Power

Substations" standard, which outlines the guidelines for equipment operation in the presence of

electromagnetic interference. The additional compliance validation will expand applications for the

OPTI-6100 in the utility industry and allow customers to benefit from the many operational efficiencies

of this platform.

“IEEE 1613 compliance provides utility companies with confidence that products meet stringent

industry standards for electromagnetic interference and will not disrupt their network operation,” said

Andrew Schmitt, directing analyst, optical, Infonetics. “Utilities represent a large percentage of nonservice

provider optical spending and the recent $4.5 billion in stimulus funding for Smart Grids will

catalyze even more spending in this sector. Products like the OPTI-6100 are a good fit for the private

optical backbones of the utilities and the custom hardware required by IEEE 1613 is a barrier to

entry”.

“This will allow us to expand the market reach of the OPTI-6100 platform,” said Jason Morgan,

director of product management, ADTRAN Carrier Networks Division. “This certification comes as a

direct result of customer requests. Already realizing the many efficiencies of the OPTI-6100, utility

customers expressed a need to extend use of the platform into other areas of their network. We are

happy to meet this need, allowing them to reap even greater rewards from their ADTRAN equipment.”

The OPTI-6100 is a high-density, compact, multi-service optical access and aggregation platform. It is

perfectly suited for delivery of high density DS1s or E1s, Ethernet over SONET/PDH, Ethernet

aggregation, TDM over Pseudowire, multiple DS3/E3 delivery, customer premises service delivery,

and mobile backhaul. Services are configured via plug-in units, which are provisioned according to

the service needs of individual locations. The flexibility of multiple plug-in units eliminates the need for

separate network elements and minimizes CAPEX and OPEX by delivering TDM and Ethernet

services from a single system.
