Synchronizing Network Time

29

Selecting Public NTP Servers

1

From any computer with internet access, access the following website:

http://www.eecis.udel.edu/~mills/ntp/clock1.htm

2

From the website, record the IP addresses for two separate active servers. One 
is used as the primary NTP server, and the other is used as the secondary NTP 
server. We recommend choosing NTP server locations that are as close to the 
Media Gateway chassis as possible.

Setting the NTP

Parameters

Use NTP to synchronize the time across the network. The NTP parameters must 
be set for the HiPer NMC card in each Media Gateway chassis, the 
Gatekeepers, SIP Proxy Servers, and the Back-end Servers.

All Media Gateway chassis components are automatically synchronized 
through the controlling HiPer NMC after it is configured for NTP.

Setting the NTP Parameters for the HiPer NMC

For the HiPer NMC card in each Media Gateway chassis, do the following:

1

Using IP Telephony Manager, open the Media Gateway chassis.

2

Select the HiPer NMC card.

3

Click 

Configuration, 

then

 Programmed Settings 

from the IP Telephony 

Manager Console window.

4

Select 

Network Time Protocol

 from the Parameter Group drop-down list.

The Network Time Protocol windows appears.
