ADTRAN TSU 600 user manual Normal CSU Timing

Chapter 1. Introduction

Normal (CSU) Timing

The typical timing option arrangement is shown in Figure 1-8. The PBX is looped timed sending data to the TSU 100 which is actually synchronous to the received data. The Network Interface (NI) is the actual source of all timings. This timing option is the same as that typically used for CSUs. This is the preferred mode for use with a PBX application.
