The T1 and E1 channelized application examples in this section are one of two types. The first type is
where a single T1 or E1 data stream is routed to and from the DS31256. This is represented as a thin
arrow in the application examples
second type is where four T1 or E1 data streams have been TDM into a single 8.192MHz data stream,
which is routed to and from the DS31256. This type is represented as a thick arrow in
