This method for TOD clock synchronization, which applies to certain communication servers, uses the Avaya Site Administration tool installed on a client computer to set up a synchronization task schedule.

You must install Avaya Site Administration on the client computer along with the NTP or SNTP software. Connect the client computer to an Internet Time Server so that the computer can continuously poll the Internet Time Server for the UTC time. Synchronize the client clock time with the clock time of the switches on the network using the Avaya Site Administration Time Synchronization feature.

On communication servers with software releases prior to R11, the synchronization command is ignored if the minute time specified for the incoming time is the same as that currently being counted at the switch. Consequently, this synchronization method is only accurate to within 59 seconds or less on communication servers that are installed with releases prior to R11.

On communication servers that are installed with a software release of R11 or later, if the minute time specified for the incoming synchronization command is the same as that being counted at the switch, the minute count on the switch is set back to the 0-second mark for the minute. When potential network delays are factored in, this method is accurate to within 5 seconds or less.
