Last month, Verizon revised its Technical Purchasing Requirement VZ.TPR.9203 to include testing requirements by location for wireless Network Equipment Building System (NEBS) equipment.  Issue 5 replaces Issue 4, which dated from March, 2009.

Wireless equipment is a small, but growing, portion of the overall NEBS market.

VZ.TPR.9203 Issue 5 includes a new “Table 2,” which details wireless requirements by location for testing to GR-63-CORE Issue 3 (environmental simulation), GR-1089-CORE Issue 4 (electromagnetic compatibility and safety), and VZ.TPR.9205 TEEER (energy efficiency). 

Issue 5 maintains Table 1, which details testing requirements by location for “wireline” or landline NEBS equipment.  

For wireless, equipment located in Mobile Switching Centers (MSC) has the most testing requirements, followed by Hubs, and Cell Sites, which has the fewest testing requirements.

In other Verizon NEBS news, the telecom giant issued this month a new Technical Purchasing Requirement – VZ.TPR.9508 – to define the minimum required NEBS and battery reserve testing for VRLA batteries supporting FiOS services.

Verizon NEBS compliance is gained through the Verizon Independent Testing Laboratories (ITL) NEBS Testing Certification Program (NEBS-TCP).  MET Labs is one of the independent labs recognized by Verizon under the NEBS-TCP program.

On a recent trip to Disney World, we were impressed with Epcot’s Test Track, a General Motors-sponsored ride.  Not only is it thrilling, it is highly educational, introducing the concepts of automotive electromagnetic compatibility, safety, and environmental simulation to the general public.

Like all the best Disney rides, the experience begins in the pre-ride waiting area, where the line snakes through a model of an EMC chamber.   

During the ride, the 6-seat vehicle undergoes the safety and quality tests that General Motors performs on every prototype it manufactures.

Most impressive is the demonstration of automotive environmental simulation testing.  The car passes through an area that blasts passengers first with heat lamps, then with cold guns, for a reported 100 degree variation.  Then robotic arms perform a corrosion test using misted salt water.

The ride spans nearly a mile and lasts 5 minutes, but it seemed much shorter.  We went straight from the ride’s exit to its entrance, to do it all over again.
