The Two-Wire Voice (V2W/V2T) Module’s
technical specifications are shown in Table 12-2.
12.4.1 Status Indicators
This module has five status indicators, as shown
in Figure 12-6. The only difference between the
V2W and the V2T LEDs is the location of the
“ring” and “busy” LEDs. As Figure 12-6 shows,
the V2W has the “busy” LEDs on the left and the
“ring” LEDs on the right, as you look at the front
of the chassis. On the V2T, the “ring” LEDs are on
the left and the “busy” LEDs are on the right.
