LIU-Framer Interface
LIU-Framer Physical Interface
The transmit framer-LIU interface for the TFRA08C13 consists of the TND, TPD, and TLCK pins. In normal opera-
tions, TND, TPD, and TLCK are driven from the transmit framer and are connected to an external transmit line inter-
face. The receive framer-LIU interface for the TFRA08C13 consists of the RPD, RND, and RLCK internal signals. In
normal operations, RND, RPD, and RLCK are sourced from an external receive line interface unit and are directly
connected to the receive framer. Figure 5 illustrates the interfaces of the transmit and receive framer units.
