Figure 2-22. Dual Terminal Multiplexer Configuration
The two terminals are completely independent of each other in terms of data channels; there is no
drop and insert functionality, and no time slots pass between the two. However, they share the same
power supply and alarm system; an alert or alarm condition on either of the two terminals causes the
shelf to display ALERT or ALARM.
2.2.3 Point-to-Point Systems
The simplest type of ACS-160 system configuration is a point-to-point system, two terminal
multiplexers connected by a single T1 circuit (Figure 2-23). The same payload circuits appear at both
ends of a point-to-point system.
Figure 2-23. Point-to-Point System
Most payload types, such as voice and full-duplex data circuits, have both an input and an output at
each terminal multiplexer. However, some payload types, like simplex data and one-way program
audio channels, have an input at one multiplexer and an output at the other, with no return signal.
