30.3.2 External NTP Servers Setup - Option 2

In the Setup Option 2 below, the EMS server uses two Stratum-2 NTP servers as its

NTP clock source and the Media Gateway also uses two Stratum-2 NTP servers as its

NTP clock source. Therefore, when this setup option is used, both the EMS and the

Media Gateway each receive their NTP clock directly from the external NTP server.
