Standards Development

Prior to founding AST Technology Labs, Inc. in 1995, James Bress was a Bellcore Member of the Technical Staff (MTS) and senior engineer which developed Caller-ID product and network requirements. Mr. Bress authored Bellcore SR-2476, Customer Premises Equipment Compatibility Considerations for the Voiceband Data Transmission Interface, and SR-3004, Testing Guidelines for Analog Type 1, 2, and 3 products.

AST Technology Labs is a contributing member of the Bluetooth® SIG eAudio task force developing standards for communication devices.

AST contributed to the development of the Consumer Technology Association (CTA) (formerly known as CEA) standard for ANSI-CTA-2051 Personal Sound Amplification Products (PSAP).

AST Technology Labs provides leadership to, and contributes to the standards developed by, the Telecommunications Industry Association (TIA) TR41 committee, Performance and Accessibility for Communications Products.
