single-channel simplex
1Simplex signaling — (SX): Signaling in which two conductors are used for a single channel, and a center tapped coil, or its equivalent, is used to split the signaling current equally between the two conductors. Note: SX signaling may be one way, for intra central… …
2Channel (communications) — Old telephone wires are a challenging communications channel for modern digital communications. In telecommunications and computer networking, a communication channel, or channel, refers either to a physical transmission medium such as a wire, or …
