High-performance equipment describes telecommunications equipment that has the performance characteristics required for use in trunks or links, is designed primarily for use in global and tactical systems, and sufficiently withstands electromagnetic interference

Electromagnetic interference

Electromagnetic interference is disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit...

 when operating in a variety of network

Telecommunications network

A telecommunications network is a collection of terminals, links and nodes which connect together to enable telecommunication between users of the terminals. Networks may use circuit switching or message switching. Each terminal in the network must have a unique address so messages or connections...

or point-to-point circuits.

Note: Requirements for global and tactical high-performance equipment may differ.
