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.
