Configuring the Stratum 3–4 Clock Timing
Data and voice transmit most efficiently (with the least amount of cells lost
per second) if a proper clock timing source is present in the PSAX 20.
Therefore, we recommend that you configure the Stratum 3–4 clock timing
before configuring any I/O or server modules.
Note:
You can avoid any system timing errors by configuring the
Stratum 3–4 clock timing before you configure and run traffic
through any I/O and server modules, DSP, or T1/E1 components.
Note:
On the Stratum Configuration window, you establish the source
of the system synchronization. You must configure the
Stratum 3–4 module before configuring any user-selected I/O or
server modules. You must configure the Stratum 3–4 clock timing
before configuring any user-selected I/O or server modules. After
you have configured the Stratum 3–4 clock timing, it provides the
reference clock to all I/O module ports configured for local timing.
