Block Diagram
User-Network Interface Block Diagram
YTD439 is best-suited for applications in terminal equipment with built-in DSU (TA, TE1)
such as terminal adapters and remote routers with built-in DSUs.
YTD439 contains a DSU function, which is necessary between the ISDN switch and the user-
network interface, and layer 1 and layer 2 functions, which are required of ISDN system
equipment. By adding minimal peripheral parts such as microprocessor and CODEC, terminal
equipment can be optimally configured.
