Description: Manages Symmetricom 1PPS timing signal output configuration and pulse accuracy state.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is SYMMCOMMONPPS?
SYMMCOMMONPPS is a Symmetricom proprietary MIB covering common 1PPS (one-pulse-per-second) timing input/output status and configuration on Symmetricom timing equipment. It exposes objects for configuring and reporting the state of PPS signal inputs and outputs, which are used to distribute precise timing between synchronization devices. Monitoring it is fundamentally about verifying hardware timing signal health, such as confirming a PPS output is present and accurate, or detecting a missing or degraded PPS input that would indicate a cabling or reference-source problem. It is described as a "common" module intended to be shared across multiple Symmetricom timing product lines, and it likely works alongside other Symmetricom clock-state MIBs such as the output-generator MIB. It is deployed in precision timing and synchronization environments, such as telecom central offices or GPS-disciplined clock distribution systems, where engineers can download the SYMMCOMMONPPS file to load it into their timing management tools.
IPNetwork Monitor allows you to monitor SNMP objects defined in SYMMCOMMONPPS. 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
- Symmetricom timing/synchronization appliance (PPS-capable clock equipment)
Monitoring Examples
No concrete object or table names were provided in the sampled source for this MIB. In general, an operator would poll this MIB's PPS status objects to confirm the 1PPS output pulse is present and within its expected accuracy tolerance, and check the PPS input status to detect loss of the external timing reference. A missing or jittery PPS signal reported here would point to a cable fault or a failing timing reference before it causes downstream clock drift.
What Can Be Monitored
- 1PPS output presence/status
- 1PPS input signal status
- pulse timing accuracy
- PPS configuration state
