Internal Timing
The TSU ACE is the source of timing. The TSU ACE 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 5-5.

PORT MENU

Use this menu to select and configure the parameters associated with the V.35 port.
RATE 56/64
Sets the base rate of the interface. The actual data rate depends on the number of
DS0s assigned to the Nx port. The DTE data rate versus the number of DS0s appears
in Appendix B, DTE Data Rate Chart, on page 53.
