Name of problem
Ensuring the time on SIP Telephones meets local conditions.
Products affected
46XX and 96XX Session Initiation Protocol (SIP) Telephones.
Problem description
The PSN 1181u described what must be done with 46XX and 96XX SIP Telephones with regards to Daylight Saving Time for the
United States and Canada. Countries outside of North America should implement what their country uses for start and stop dates of
Daylight Saving Time.
Resolution
The following two lines must be included in the 46xxsettings.txt file, replacing any existing settings for these parameters that may
already be in the file:
SET DSTSTART "XSunMonthYL"
SET DSTSTOP "XSunMonthYL”
Where X is the 1
st
, 2
nd
, 3
rd
, 4
th
, or 5th Sunday of the month and Y is the hour in AM local standard time.
For example, in Germany, Daylight Saving Time started on Sunday, 30
th
of March 2008 at 2:00 AM local standard time and stopped
on Sunday, 26
th
of October 2008 at 3:00 AM local daylight time. So using Germany as the example, the parameters to be included in
the 46xxsettings.txt file would be:
SET DSTSTART "5SunMar2L"
SET DSTSTOP "4SunOct3L”
The telephones must then be reset for the change to take effect. Further information can be found in the 4600 Series IP Telephone LAN
Administrator Guide, in the section of "Setting the Date and Time on SIP IP Telephones".
