Figure 15-2 shows an application where up to 40 T1 or E1 ports are interfaced to a single DS3131. In this
application, the quad T1 and E1 transceivers (DS21Q352/DS21Q552/DS21Q354/DS21Q554) perform
the line interface function and frames to the T1 or E1 line. The local bus (if enabled) can be used to
configure and monitor the T1/E1 transceivers.
