Accurate System timing is important for the proper operation of the Sonus SBC 1000/2000. The system time may be sourced from different places depending upon the specific topology where the Sonus SBC 1000/2000 is deployed. In some cases the Sonus SBC 1000/2000 itself may serve as a time source for the topology. In such cases, the Sonus SBC 1000/2000 may use its own independent internal clock, or it may be synchronized with a network time source through Network Time Protocol (NTP). The NTP source may be a public source such as NTP.org or NIST, or a private source such as an internal enterprise time server.
The Sonus SBC 1000/2000 allows you to configure a maximum of two NTP time servers from which to source time and date information.
Configuring the Sonus SBC 1000/2000 to Use an NTP Server
To configure your Sonus SBC 1000/2000 to use NTP:
Time Management/Network Time Protocol - Field Definitions
The Time Management panel contains fields that enable you to set the time zone and configure one or more network time sources (NTP).
