SECTION 14: APPLICATIONS

Section 14 describes some possible applications for the DS3134. The number of potential configurations

is numerous and only a few are shown. Users are encouraged to contact the factory for support of their

particular application. Contact information is shown in Table 14A.

The T1 and E1 channelized application examples shown in Section 14 will be one of two types. The first

type is where a single T1 or E1 data stream is routed to and from the DS3134.

This first type is

represented as a thin arrow in the application examples and the electrical connections are shown in

Figure 14B. The second type is where four T1 or E1 data streams have been Time Division Multiplexed

(TDM) into a single 8.192 MHz data stream, which is routed to and from the DS3134. This second type

is represented as a thick arrow and the electrical connections are shown in Figure 14C.
