VOICE APPLICATION
This voice application is similar to the point-to-point multiport
application (described on page 7-2). This application (shown in
Figure 7-5) uses two of the four DSX-1 ports on the Quad DSX-1
card to transport PBX data, including voice channels, through the
same T3 as the data. See Table 7-5 for an example configuration of
this application.
