Point-to-Point Multiplexing
The 3600 Series DSU operating in TDM mode can be
used for point-to-point circuits at speeds of up to 64 kbps.
Figure 4-6 shows a typical TDM application. In
point-to-point multiplexing, the DTEs at Port 1
communicate with one another, the DTEs at Port 2
communicate with one another, and so on. The TDM
point-to-point application provides the same functionality
as six point-to-point circuits. The DDS circuit can be
provided by a service provider or a metallic 4-wire LADS
facility.
