NetClock version 3.6.7 Release Notes
Contents
1. Version 3 4 9 e The Frequency alarm classified as a Major alarm condition is no longer being asserted immediately upon the loss of qualified GPS reception O The Frequency alarm and its associated Major Alarm was prematurely being asserted as soon as the Holdover mode started Upon initial loss of GPS reception Since during the Holdover mode the oscillator and the NetClock s outputs are still within specifications the Frequency and associated Major alarms are now only being asserted if the Holdover mode expires without qualified GPS reception being restored yet e Leap Second notification improvement for NTP when a NetClock with version 3 4 8 software currently installed is syncing to other NTP servers Note This is applicable only to NetClocks operating in a Stratum 2 or lower configuration Not applicable to NetClocks syncing via GPS or IRIG input www spectracomcorp com 7 NetClock Release Notes Resolved an issue that NTP could keep the leap second indicator bits active for 1 2 minutes after the insertion of a Leap Second causing a Leap Second notification to be asserted for the following month as well Version 3 4 8 e Improved Stratum 2 operation that was previously incorporated in version 3 4 7 e Enabled unit logs to be obtained remotely via SSH sessions in addition to telnet sessions e Fixed a minor issue with the reported Antenna Status as read using SNMP Version 3 4 7 e Enhanced NTP Stratum 2 operatio2. iced specced ac cnc ahs eps eto ca cece cess ee 2 Software enhancements iretsi ar vet E EE AEE E EE RE EEEE AEE a E ESE 5 Determining the version of software currently installed eee ceessceeneeceeeeceseeeceeneeceeaeeceaeeceeeeceeneeseeeeeeeeeees 11 Links to download NetClock software and user manual Updates 0 eeeeeeeeceeeeceseeeceeeeeceeeeeceeeeeceeeeesteeeesaeees 12 Sp ctracom Tech SUppOftsiiisiissssiesinio ian kEi eN E EEEE OEA AAEE ERE EAE EREE EEE E Eaa ER AE TEREE EDIE EAE 13 www spectracomcorp com 1 NetClock Release Notes Rev A 29 Oct 2014 New Features Version 3 6 2 e Added ability for users to be able to manually set the time o USER LCL for NTP RefID is the synchronizing reference o NTP can override USER handset time as a synchronizing reference o When time is USER set the NTP server remains in sync until reboot loss of power Holdover mode expires or until another external input reference such as GPS or NTP is restored e Allows users to set the NTP Local Clock Reference s default Stratum level o Per NTP specifications available range is Stratum 0 to Stratum 15 though it s recommended to use Stratum values of 2 through 15 only o With no external inputs present NTP selects the Local Clock Reference and NTP will become one less than its Stratum level if the Local Clock Reference is configured as Stratum 3 for instance NTP will become Stratum 4 with no external inputs present Setting this value t
3. 1 but a user can change this value to 4 if they wish for instance the GPS antenna has a partially blocked view of the sky causing it to drop to tracking only 3 satellites for periods of time throughout the day e Improved the text on the Front Panel LCD display window and on the System gt GPS Signal Status page of the web browser to more clearly indicate the input reference for synchronization e Applicable only to Option 04 Rubidium Oscillator installed Improved Rubidium oscillator 1PPS output operation o The IPPS output from the Rb oscillator will always be present and selected once the oscillator has locked even if the oscillator subsequently goes into Free Run mode and then back into lock mode again Version 3 5 0 e Fixed an issue with ASCII Data Format 90 output o While in GPS Standard mode factory default configuration the data output string was only changing the reported time every 3 seconds o While in Mobile GPS mode the data output string contained no time data e Fixed an issue with the Models 9388 and 9288 which could cause the RS 485 input to stop receiving data o If the input time being received from the NetClock reference stepped by more than one second the input time of the Ethernet time sever could stop being processed e An entry is now added in the Operational log when either the GPS receiver or SAASM GPS receiver for military DOD applications detects a leap second is pending
