nonHDLCn

nonHDLCn is a term sometimes used in networking to describe a communication scenario that does not adhere to the High-Level Data Link Control (HDLC) protocol. HDLC is a bit-oriented data link layer protocol developed by the International Organization for Standardization (ISO). It is used for point-to-point and multipoint communication. When a network or a specific link within a network is described as "nonHDLCn," it implies that it is using an alternative data link layer framing or encapsulation method. This could be due to various reasons, such as using a proprietary protocol, a different industry standard like Ethernet, or a simpler custom framing mechanism for specific applications. The "n" in nonHDLCn might indicate a specific variation or instance of a non-HDLC protocol, though its exact meaning can depend on the context in which it is used. Understanding that a link is nonHDLCn is crucial for network troubleshooting, as it dictates the expected packet structure, error detection methods, and addressing schemes that are in play. Devices and protocols designed to interoperate within a nonHDLCn environment would need to support the specific alternative protocol being employed, rather than expecting standard HDLC framing.
