IEEE 823-1989

IEEE 823-1989 defines methodologies for specifying voice grade channel transmission parameters and evaluating connection transmission performance for speech telephony. This technical standard is relevant to communication, networking and broadcast technologies because it focuses on how voice-grade channels are described and assessed. By setting a common basis for transmission measurements and performance evaluation, IEEE 823-1989 helps support consistent engineering decisions, comparison of results, and clearer acceptance criteria for speech telephony connections.

About IEEE 823-1989

IEEE 823-1989 is concerned with the technical treatment of voice grade channels used for speech telephony. Its purpose is to guide how transmission parameters are specified and how connection performance is evaluated, which can be important when comparing channel behavior across equipment or network arrangements. As a standards document in the communications field, it provides a structured way to describe performance characteristics rather than leaving interpretation to ad hoc practices. That makes IEEE 823-1989 useful for engineering, testing, and documentation work.

Where is IEEE 823-1989 used?

This standard is typically used in telephony and communications environments where voice-grade transmission paths must be assessed in a consistent way. It may be applied during network planning, equipment evaluation, lab testing, or service acceptance for speech telephony connections. Organizations working with channel interfaces, transmission systems, or voice-related communication paths can use IEEE 823-1989 to compare results and document performance more clearly. It is especially relevant where measured transmission behavior needs to be tied to defined specifications.

Importance in practice

In practice, IEEE 823-1989 helps reduce ambiguity in how voice telephony transmission performance is defined and checked. That matters for compliance, procurement, and quality control because buyers and engineers need a shared reference for what should be measured and how results should be interpreted. Using a recognized standard can also improve consistency across test setups and reduce the risk of mismatched expectations between suppliers, operators, and evaluators. IEEE 823-1989 therefore supports more reliable performance assessment.
