This parameter controls whether the displayed time will be daylight savings time or not. If set to “Yes” and the Optional Rule is empty, then the displayed time will be 1 hour ahead of normal time.

The “Automatic Daylight Saving Time Rule” shall have the following syntax: start-time;end-time;saving

Both start-time and end-time have the same syntax: month,day,weekday,hour,minute

month: 1,2,3,..,12 (for Jan, Feb, .., Dec)

day: [+-]1,2,3,..,31

weekday: 1, 2, 3, .., 7 (for Mon, Tue, .., Sun), or 0 which means the daylight saving rule is not based on week days but based on the day of the month. hour: hour (0-23),

minute: minute (0-59)

If “weekday” is 0, it means the date to start or end daylight saving is at exactly the given date. In that case, the “day” value must not be negative. If “weekday” is not zero and “day” is positive, then the daylight saving starts on the first “day”th iteration of the weekday (1st Sunday, 3rd Tuesday etc). If “weekday” us not zero and “day” is negative, then the daylight saving starts on the last “day”th iteration of the weekday (last Sunday, 3rd last Tuesday etc).

The saving is in the unit of minutes. The saving time may also be preceded by a negative (-) sign if subtraction is desired instead of addition.

The default value for “Automatic Daylight Saving Time Rule” shall be set to “04,01,7,02,00;10,-1,7,02,00;60” which is the rule for US.

Examples

US/Canada where daylight saving time is applicable: 04,01,7,02,00;10,-1,7,02,00;60

This means the daylight saving time starts from the first Sunday of April at 2AM and ends the last Sunday of October at 2AM. The saving is 60 minutes (1hour).

Default is “*00”. User can switch the phone to PSTN line connected to the Line port of ATA and make outgoing calls.

Default is NAT router mode. HandyTone-486 Rev.2.0 can be configured in Bridge mode so the device functions as a bridge.

Default is “No”. The access to configuration page via WAN port is disabled. This setting has no effect if the device is in Bridge mode.

Unit will not respond to PING from WAN side if set to “No”.
