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 AC 60.
Therefore, we recommend that you configure the Stratum 3–4 clock timing
before configuring any I/O or server modules.
Note:
On the Stratum Configuration window, you establish the source
of the system synchronization. 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.
