Internal Timing
The TSU 600 is the source of timing. The TSU 600 is
configured to use its own internal oscillator as the
source of timing. Applications include private line
driver circuits where one end is set to network and the
other to internal. See Figure 1-7.
The internal source timing is restricted from use when a
secondary interface is also used.
