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.
