Data Link Control Layer

The data link control (DLC) layer consists of the elements that provide an interface to the hardware. The DLC elements supply support for various DLC protocols, such as Synchronous Data Link Control (SDLC) and the IBM® Token-Ring Network. The DLC layer supplies a common link appearance to the elements in the path control (PC) layer. The DLC layer is common to all Personal Communications LU implementations, including LUA.
