C
- Category I.
Terminal options that perform an asynchronous multiplex function. Examples of Category I transport NE interfaces are low-speed interfaces to ADMs, digital radio terminals, fiber-optic terminals (excluding terminals that function solely as digital repeaters or regenerators), and low-speed interfaces to DACSs.
- Category II.
Equipment interfaces whose behavior with respect to timing jitter is governed exclusively by input timing recovery circuitry. Examples of Category II transport NE interfaces are digital terminals at a DLC system, repeaters for metallic cables, regenerators for fiber-optic cables, and high-speed interfaces to DACSs. STS-N and OC-N interfaces to a SONET NE are also considered Category II.
