What Is TEMPUSLXUNISON-MIB?
The TEMPUSLXUNISON-MIB is EndRun Technologies' enterprise SNMP module for its Tempus LX/Unison family of GPS-synchronized NTP time server appliances. It exposes NTP client-server statistics under the 'cntp' subtree, covering packet counters, authentication results, synchronization source and quality metrics, and internal oscillator information. Its primary role is monitoring both the software (NTP protocol) and hardware (oscillator) status of the time server — administrators track synchronization source and stratum, time figure-of-merit and offset-to-reference to gauge timing accuracy, authentication failures for security, and oscillator type/status, all critical health indicators for a device whose sole job is delivering accurate time. As a time-server appliance MIB, it is closely tied to standard NTP protocol concepts (stratum, leap indicator) even though implemented as EndRun's own enterprise MIB rather than an IETF NTP MIB. It is deployed wherever an EndRun Tempus LX/Unison unit provides GPS-disciplined NTP time to a network, monitored to ensure the time source remains accurate and trustworthy. Engineers can download the TEMPUSLXUNISON-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in TEMPUSLXUNISON-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- EndRun Technologies Tempus LX/Unison GPS-synchronized NTP time server appliance
Monitoring Examples
An operator would poll cntpSyncSource and cntpStratum to confirm the appliance is properly disciplined to its GPS reference and reporting a low (authoritative) stratum, while cntpTimeFigureOfMerit and cntpOffsetToCDMAReference quantify current timing accuracy. Rising cntpAuthFail or cntpDroppedPkts counts alongside cntpRxPkts/cntpTxPkts would indicate NTP clients failing authentication or experiencing packet loss against this time server, and cntpOscType/cntpLeapIndBits reveal the internal oscillator type and any pending leap-second adjustment.
What Can Be Monitored
- NTP packets received/transmitted
- ignored/dropped packets
- authentication failure count
- synchronization source
- NTP stratum level
- time figure of merit / offset to reference
- oscillator type
- leap indicator bits

How to Use in IPNetwork Monitor
Example using cntpRxPkts OID:
Select an EndRun Technologies Tempus LX/Unison GPS-synchronized NTP time server appliance (sync status/oscillator health) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cntpRxPkts into the Find box to locate it in the OID tree, then select it and click OK. It reports the total number of NTP request packets received by the NTP daemon. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

| INT cntpTimeFigureOfMerit | 1.3.6.1.4.1.13827.5.0.6 | INTEGER | read-only | The Time Figure of Merit (TFOM) value ranges from 6 to 9 and indicates the current estimate of the worst case time error. It is a logarithmic scale, with each increment indicating a tenfold increase in the worst case time error boundaries. The scale is referenced to a worst case time error of 100 picoseconds, equivalent to a TFOM of zero. During normal locked operation with CDMA the TFOM is 6 and implies a worst case time error of 100 microseconds. During periods of signal loss, the CDMA sub-system will compute an extrapolated worst case time error. One hour after the worst case time error has reached the value equivalent to a TFOM of 9, the NTP server will cease to send stratum 1 reply packets and an Alarm LED will be energized. |
| INT cntpLeapIndBits | 1.3.6.1.4.1.13827.5.0.7 | INTEGER | read-only | This is a status code indicating: normal operation, a leap second to be inserted in the last minute of the current day, a leap second to be deleted in the last second of the day or an alarm condition indicating loss of timing synchronization. The leap indicator field of NTP reply packets sent from this server is set to cntpLeapIndBits. |
| STR cntpSyncSource | 1.3.6.1.4.1.13827.5.0.8 | DisplayString | read-only | This is an ASCII string identifying the synchronization source for this NTP server. It is one of CDMA, an IP address of a stratum 1 server, or NONE. If it is NONE, then the server is not synchronized, has its Leap Indicator Bits in the Alarm state and is running at Stratum 16. If it is an IP address, then the server is operating as a stratum 2 server synchronized to the network connected stratum 1 server whose IP address is shown. Check the Stratum, Leap Indicator Bits and Time Figure of Merit for further information. NTP reply packets from this server will have the reference identifier field set to cntpSyncSource if it is CDMA. Otherwise it will be set to either an IP address or 0.0.0.0 (NONE). |
| STR cntpOffsetToCDMAReference | 1.3.6.1.4.1.13827.5.0.9 | DisplayString | read-only | This is an ASCII string containing the floating value of the current offset in units of seconds of the NTP server CPU clock to the CDMA reference time. Positive values imply that the NTP server clock is ahead of the CDMA reference time. |
| INT cntpStratum | 1.3.6.1.4.1.13827.5.0.10 | INTEGER | read-only | This is an integer showing the current stratum level being reported by the NTP daemon in its reply packets to clients. If it is 1, then the server is fully synchronized and delivering Stratum 1 accuracy. If it is greater than 1 and less than 16, it is synchronized to a network connected NTP server operating at one stratum lower. If it is 16, then the server is unambiguously unsynchronized. NTP clients on the network should be configured to not use the time from this server if the stratum is 16. |

| BIT cdmaFaultStatus | 1.3.6.1.4.1.13827.5.1.1 | Bits | read-only | This is a bit string contained in one character representing the least significant two nibbles of the CDMA fault status word. Unfortunately, SNMP numbers the bits in the reverse order, so that the enumerated values are backwards from the description contained in the User's Manual for the fault status field returned by the cdmastat command. Each bit indicates a fault when set. Currently defined fault states encoded in this value: Bit 7: DAC controlling the TCXO is near the high or low limit. Bit 6: Time Figure of Merit has been 9 (unsynchronized) for 1 hour. Bit 5: Field Programmable Gate Array (FPGA) did not configure properly. Bit 4: FLASH memory had a write fault. Bit 3: Local Oscillator PLL fault. Bit 2: CDMA reference time fault (fails sanity checks). Bit 1: NTP daemon is not polling the CDMA reference clock. Bit 0: Not Used. |
| INT cdmaTimeFigureOfMerit | 1.3.6.1.4.1.13827.5.1.2 | INTEGER | read-only | The Time Figure of Merit (TFOM) value ranges from 6 to 9 and indicates the current estimate of the worst case time error. It is a logarithmic scale, with each increment indicating a tenfold increase in the worst case time error boundaries. The scale is referenced to a worst case time error of 100 picoseconds, equivalent to a TFOM of zero. During normal locked operation the TFOM is 6 and implies a worst case time error of 100 microseconds. During periods of signal loss, the CDMA sub-system will compute an extrapolated worst case time error.

The value ranges from 0 to 511 and is in units of 64 Pseudo Noise Code chips. This offset serves as a base station identifier that is analogous to the Pseudo Random Noise (PRN) codes used by the individual satellites in the GPS system. |
| INT cdmaAGC | 1.3.6.1.4.1.13827.5.1.6 | INTEGER | read-only | Current 8 bit, Automatic Gain Control (AGC) DAC value. Typical values are around 200, but proximity to the base station, type of building construction and orientation within the building have a strong influence on this value.

| BIT gpsFaultStatus | 1.3.6.1.4.1.13827.6.1.1 | Bits | read-only | This is a bit string contained in one character representing the least significant two nibbles of the GPS fault status word. Unfortunately, SNMP numbers the bits in the reverse order, so that the enumerated values are backwards from the description contained in the User's Manual for the fault status field returned by the gpsstat command. Each bit indicates a fault when set. Currently defined fault states encoded in this value: Bit 7: DAC controlling the TCXO is near the high or low limit. Bit 6: Time Figure of Merit has been 9 (unsynchronized) for 1 hour. Bit 5: Field Programmable Gate Array (FPGA) did not configure properly. Bit 4: FLASH memory had a write fault. Bit 3: GPS engine communication fault. Bit 2: GPS reference time fault (fails sanity checks). Bit 1: NTP daemon is not polling the GPS reference clock. Bit 0: GPS antenna or feedline is shorted or open. |
| INT gpsTimeFigureOfMerit | 1.3.6.1.4.1.13827.6.1.2 | INTEGER | read-only | The Time Figure of Merit (TFOM) value ranges from 3 to 9 and indicates the current estimate of the worst case time error. It is a logarithmic scale, with each increment indicating a tenfold increase in the worst case time error boundaries. The scale is referenced to a worst case time error of 100 picoseconds, equivalent to a TFOM of zero. During normal locked operation the TFOM is 4 and implies a worst case time error of 100 nanoseconds. During periods of signal loss, the GPS sub-system will compute an extrapolated worst case time error. One hour after the worst case time error has reached the value equivalent to a TFOM of 9, the NTP server will cease to send stratum 1 reply packets and an Alarm LED will be energized. |
| INT gpsSigProcState | 1.3.6.1.4.1.13827.6.1.3 | INTEGER | read-only | Current GPS signal processor state. One of 0, 1 or 2, with 0 being the acquisition state and 2 the fully locked on state. |

| INT gpsCurrentLeapSeconds | 1.3.6.1.4.1.13827.6.1.9 | INTEGER | read-only | This value is the current difference in seconds between GPS time and UTC time. GPS time is ahead of UTC time by this amount. |
| INT gpsFutureLeapSeconds | 1.3.6.1.4.1.13827.6.1.10 | INTEGER | read-only | This value is the future difference in seconds between GPS time and UTC time. Leap seconds may be inserted or deleted from the UTC timescale twice during the year: Dec 31 and June 30 at UTC midnight. If this value is the same as cdmaCurrentLeapSeconds, then no leap second insertion or deletion will occur at the next possible time. If it is different, then the change will take affect at the next possible time. GPS time will be ahead of UTC time by this amount. |
