Upgrade Your Meridian CDMA Frequency Reference
Free software upgrades

We provide upgrades and enhancements to our products at this site for no charge.  The software available on this page is for the Meridian CDMA Frequency Reference.

NOTE: You do not need to upgrade software everytime we release a new version.  This is because the software installed in the Meridian is a shared code base used by other products - the Unison, the Tempus LX, and the Tycho.  Sometimes we make changes or add features that are not relevant to the Meridian.  Read the history of changes below to see if upgrading software makes sense for you.

History of Software Changes for Linux Subsystem
(Software Numbers 6010-0042-000 and 6010-0044-000)
Version
Changes
5.70 Patches applied to correct Shellshock vulnerabilities.  Please see Field Service Bulletin FSB140926-02.
RECOMMENDATION: Please upgrade unless you have secured the network port on your Meridian per the instructions in the Bulletin.

NOTE 1:  If you are upgrading and the current version in your unit is 5.50 or less, then please read this first.
NOTE 2:  IPv6 users - If you want the IPv6-capable kernel then click here to download.  For information on IPv6 capabilities read these release notes.
5.67 Minor bugs fixed in the PTP option.
RECOMMENDATION: No need to upgrade unless you have the PTP Option.
5.64 1. Fixed bug where sometimes, at first power-up after being shipped from factory, the NTP daemon would take a longer time than normal to indicate lock status.
2. Fixed bug in HTTP interface where it reports NTP Stratum 16 when the actual Stratum is any level greater than 2.
3. Fixed bug introduced at version 5.60 where the ntp daemon continues to serve Stratum 1 time after receiver subsystem goes unlocked for an extended period.
4. Dual power supply option: Added ability to inhibit Alarm LED and Alarm Open-Collector Output from going active if one of the power supplies fails or is not powered.  New commands are PWRFLTMASK and SETPWRFLTMASK.
RECOMMENDATION: No need to upgrade unless one of these items is important to you.
5.63 Fixed minor bug - erroneous SNMP traps when NTP is flooded with packets.
RECOMMENDATION: No need to upgrade unless this is important to you.
5.62 1. PTPv2 Option: Removed PTP "Port State = Listen" which could prevent the clock from becoming "Port State = Master".
2. Fixed polling fault that may occur when the unit is powered up the very first time only.
RECOMMENDATION: Upgrade if one of the above items is important to you.
5.61 1. PTP Option: Fixed mishandling of packet sequence numbers when packets are dropped.
2. Fixed bug where password is displayed when upgrading firmware using the Web Interface.
3. Fixed bug that prevents you from upgrading firmware using the Web Interface and the "Upgrade From Local File" option.  Because of this flaw in your current version you must upgrade using the Web Interface and the "Upgrade From FTP Server" option, or by using the command line interface.
4. Fixed bug introduced with change to NTP distribution 4.2.6p3 where ntpd would terminate if user did not configure network settings.
RECOMMENDATION: Upgrade if you have the PTP Option or use the Web Interface.
5.60 1. Updated NTP distribution version to 4.2.6p3 which solves the vulnerability below (item #5) and also improves timing jitter performance.
2. Added version 2 for PTP/IEEE-1588.  This only pertains to those who have purchased the PTP Option.
3. Fixed network domain name bug for domains with more than one '.' in them.
4. Fixed rare Secure Shell permissions bug.
5. Workaround for ntpq/ntpdc remote query vulnerability.  Did this even though the updated NTP distribution should solve the problem.
RECOMMENDATION: Upgrade if one of the above items is important to you.
5.50 1. Added capability for PTP/IEEE-1588 Option that allows setting of multicast time-to-live (ttl) variable.
2. Added capability to edit and view the Domain Name Server (DNS) via the front-panel keypad/display.
3. Fixed a bug related to erroneous SNMP FaultStatus2 traps.
4. Fixed a bug in the SNMP MIB related to the plug-in options.
5. Added Web Interface (HTTPS) for monitoring status of all functions and for upgrading software.  This new capability is only for units with Software Number 6010-0044-000.  The Web Interface is disabled for units with Software Number 6010-0042-000 (because these are older units and the required hardware is not available).
RECOMMENDATION: Upgrade if one of the above items is important to you.
5.11 Fixed a bug related to the csysuser login.  If you are having trouble logging in to your unit then upgrading your software will not correct the problem.  Please see this Field Service Bulletin.
RECOMMENDATION: No need to upgrade.
5.10 New option added to the product line: Precision Time Protocol (PTP/IEEE-1588).
RECOMMENDATION: No need to upgrade.
5.00 First software release for Meridian CDMA Frequency Reference.
