DTE Timing
The DTE is the source of timing. The TSU 600 uses the incoming DTE
clock to determine the transmission timing. This is typically used in ap-
plications where it is necessary to have the DTE as the primary clock
source (such as limited distance line drivers). See Figure 5-3.
The DTE source timing is restricted from use when a secondary interface
is used at the same time.

U-BR1TE (Slot 1)
The timing mode selection U-BR1TE (Slot 1) works much like DTE tim-
ing except that the clock is derived from the U interface.
