14 APPLICATIONS AND STANDARDS OVERVIEW
Application Examples
and Figure 14-2 detail two possible applications of the DS3112. Figure 14-1 shows an
example of a channelized T3/E3 application. It shows the DS3112 being used to multiplex and
demultiplex a T3/E3 data stream into either 28 T1 data streams or 16 E1 data streams. The demultiplexed
T1/E1 data streams are fed into the DS21FF42/44 16-channel T1/E1 framer and the DS21FT42 12-
channel T1 framer devices. The T1/E1 framers locate the frame boundaries and concatenate four T1/E1
data streams into one 8.192MHz data stream, which is feed into the DS3134 HDLC controller.
Figure 14-2 shows an example of a dual unchannelized T3/E3 application. In this application, the
multiplexing capability of the DS3112 is disabled and it is only used as a T3/E3 framer.
