The AT&T ISDN Testing Program helps CPE vendors ensure that their multiplexer, PBX, router and similar equipment take full advantage of AT&T's ISDN PRI.

Service at turn-up is smooth. Testing helps to ensure that the products you have developed will work with our network and all the jagged edges are gone.

Testing identifies potential problems in the lab, not at customers' locations. Your customers will know that they own a product that has tested compatible and interworks with AT&T's ISDN. Testing also decreases maintenance costs. And it's free.

Conformance Testing (Currently Only PRI)

• Performed to specification TR 41459

• Verifies that the product implementation demonstrates proper functionality when connected to a laboratory-based AT&T network test platform.

• Performed at AT&T's Conformance Labs in San Francisco, CA and Washington, D.C.

• Follows rigorous procedures designed by AT&T Bell Laboratories.

• Performed in two phases:

  • Remote: at the vendor's location

  • On-site: at AT&T's Conformance Labs

• Vendors who pass the conformance testing program:

  • are identified to AT&T's ISDN consultants and field engineers

  • can advertise that their products were tested by AT&T.

Interoperability Testing

• Determines application layer, end-user feature interworking with AT&T's ISDN network.

• Executed over a live network representing a typical customer's configuration.

• Verifies end-to-end connectivity and performance.

• Performed at AT&T's Interoperability Labs in Holmdel, N.J.

  APPLICATIONS

  • Remote Local Area Network Access

  • Access to the Internet

  • Video Services

  • ...and others.

Demonstration Facilities

Labs using AT&T's live network are located in Holmdel, N.J. and San Francisco, CA. Arrangements can be made for CPE vendors to have their equipment demonstrated at either lab.

There is no charge for these programs.
