Summer Time (Daylight Saving Time) Setting:The start and end dates of the summer time can be programmed. The clock will be adjusted (one hourforward or backward) at 2:00 AM of the programmed date, if enabled through system programming. Itmeans 2:00 AM will become 3:00 AM on the start date of the summer time, and 2:00 AM will become1:00 AM on the end date.b. Time Information through Network Time Protocol (NTP):By connecting the Control Box to an NTP server, it is possible to receive and update the time setting.The clock will be adjusted every day at 3:05 AM, if enabled through system programming.Conditions• SMDR will record the call information using the Control Box clock so that the recording time will beoverlapped at the end of summer time.PC Programming Manual References10.1.1 Control Box Configuration—[2-1-1] System—Date & Time—Date & Time Setting10.1.2 Control Box Configuration—[2-1-2] System—Date & Time—SNTP / Daylight Saving—Automatic TimeAdjustment—Automatic Time Correction on Stand-alone mode10.1.2.1 Control Box Configuration—[2-1-2] System—Date & Time—SNTP / Daylight Saving—DaylightSavingFeature Manual References2.6.1.1 Station Message Detail Recording (SMDR)4.4.4 Dynamic Host Configuration Protocol (DHCP) ServerDescriptionThe Control Box has a built-in DHCP server.
