Chapter 5. Configuration Menu5-8 TSU 120 User Manual 61202129L1-1DTE TimingThe DTE is the source of timing. The TSU 120 uses the incom-ing DTE clock to determine the transmission timing. This istypically used in applications where it is necessary to have theDTE as the primary clock source, (such as limited distance linedrivers). See Figure 5-4.Figure 5-4.
