DTE Timed
The DTE is the source of timing. The TSU 120 uses the
incoming DTE clock to determine the transmission
timing. This is typically used in applications where it
is necessary to have the DTE as the primary clock
source, (such as limited distance line drivers). See
Figure 1-6.
The DTE source timing is restricted from use when a
secondary interface is used at the same time.
