TA 544 User Manual/61200704L1-1APage 21 of 68© 2001, ADTRAN, Inc. TA 544 User ManualBaud RateThis is the asynchronous rate that the maintenance port will run. The possible values are 300, 1200, 2400,4800, 9600 (def), 19200, 38400, and 57600.Data BitsThis is the asynchronous bit rate that the maintenance port will run. The possible values are 7 or 8 (def) bits.ParityThis is the asynchronous parity that the maintenance port will run. The possible values are NONE (def), ODD,or EVEN.Stop BitsThis is the stop bit used for the maintenance port. The possible values are 1 (def), 1.5 or 2.> Network TimeThe TA 544 unit time can be entered manually from the SYSTEM INFO menu, or the unit can receive time from an NTP/SNTP server. The N ETWORK T IME menu includes all parameters relating to how the unit communicates with the timeserver.Server TypeThe server type defines which port the TA 544 will listen on to receive timing information from the timeserver.NT TimeThe TA 544 will receive time from an NT server running SNTP software on its TIME port.SNTPThe TA 544 will receive time directly from an SNTP server.ActiveThis network timing feature can be turned on and off. It determines whether the unit will request and receivetime from a time server.Time ZoneThere are several time zones available for the time to be displayed in. All time zones are based off of Green-wich Mean Time (GMT).Adjust for Daylight SavingSince some areas of the world use Daylight Savings Time, theTA 544 is designed to adjust the time on thefirst Sunday in April and the last Sunday in October accordingly if this option is turned on.Host AddressThis is the IP address of the time server that theTA 544 will request and receive time from.RefreshThis is the interval of time between each request theTA 544 sends out to the time server. A smaller refreshtime guarantees that the unit receives the correct time from the server and corrects possible errors morequickly, but it is more taxing on the machine. A range of refresh times is available for the user to decidewhich is best for their unit.
