channel number (CN)

Like the Channel Identifier (CID), the Channel Number (CN) is a channel identifier. In Datex-P, where this designation is also used, it is a reserved channel address(layer 3) on the main port (P10H). Reserved channel numbers realize logical channels in the third layer (OSI), the logical partial link transmissions for simultaneous routing of several virtual connections (multiple operation) between the data terminal equipment (DTE).
