Figure 15-3 shows an application where three T3 or E3 framers are interfaced to a single DS3131. The
DS3131 is used to terminate both the payload of the T3 or E3 link as well as the overhead channels (like
the C bits in a T3 application). The local bus (if enabled) can be used to configure and monitor the T3/E3
framers.
