DTE Timing
The DTE is the source of timing. The TSU 610 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 4-7.
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 timing except that the clock is derived from the U
interface.
