NTP Servers
Overview
Purpose
This appendix presents the available NTP servers.
NTP Servers: US
The Alcatel-Lucent OmniTouch Advanced Communications Server requires an external
time reference to maintain the accuracy of its system clock. If you do not run a NTP server
within your organization, you may use one of the publicly accessible time servers used by
the NIST Internet Time Service (ITS). The OmniTouch ACS server ships with
us.pool.ntp.org as the default. This is an NTP round robin, giving a different NTP server
with each access. This assures that if one NTP server is unavailable, another will be
accessed.
However, if you prefer to use a single NTP server, the table below lists publicly accessible
servers. It was obtained at http://www.boulder.nist.gov/timefreq/service/time-servers.html
