ADTRAN TSU 600 user manual Internal Timing, Internal Clock Source

Chapter 1. Introduction

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.
