DS3134

203 of 203

Single T3 with 672 HDLC Channel Support

Figure 14G shows an application where a T3 line is interfaced to three DS3134. In this application, the

T3 line is demultiplexed by the M13 block and passed to the DS21FF42 Four x Four 16 Channel T1

Framer and DS21FT42 Four x Three 12 Channel T1 Framer devices. The T1 framers locate the frame

and multiframe boundaries and interface to the DS3134. In this application, aggregating four T1 lines

into a single 8.192 MHz data stream is not required since the DS3134 has enough physical ports to

support the application but aggregation could be done to cut down on the number of electrical connections

between the DS3134 and the T1 framers. The T1 lines can be either clear channel or channelized.
