ISDN

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.
