MT56DSU-R Owner's Manual
Local Area Data Set Application
In this application, two pairs of wires provide the connection
between two MT56DSU-R devices. The two pairs can be up to the
equivalent of 3 miles of 26 AWG wire at 56000 bps, or longer for
subrate applications (see distances chart in section 3.4.1 of this
manual).
The figure below depicts a typical Local Area Data Set application.

External Clocking Application
This application is similar to theLocal Area Data Set application
except for the timing option setting. In the example below, the DTE
connector of the T1 mux is connected to the DTE connector of the
MT56DSU-R. Here, the MT56DSU-R must receive timing
information from the T1 mux. The MT56DSU-R is set for external
timing in this type of application. At the DTE end, DDS timing is
selected, providing normal clocking to the DTE.
The figure below shows a typical External Clocking application.
