Description: Manages Symmetricom DTI Digital Timing Interface configuration, port state, and timing signal.
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 SYMMCOMMONDTI?
SYMMCOMMONDTI is a Symmetricom, Inc. module covering the Digital Timing Interface (DTI) common to Symmetricom's precision timing/synchronization products, split into status and configuration nodes for DTI ports. It exposes DTI port operational status and timing-signal configuration used to distribute precise time/frequency references between equipment. Its monitoring focus is on hardware/software timing status: whether a DTI port is up and correctly receiving or distributing its timing reference, which is critical because loss of DTI sync can cascade into timing errors across dependent network equipment (e.g., telecom switches). It is a common/shared module referenced by other Symmetricom timing-product MIBs rather than a standalone standard. It is deployed on Symmetricom timing/synchronization units (e.g., GPS-disciplined clocks) used in telecom central offices and other precision-timing environments. Engineers can download the SYMMCOMMONDTI file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in SYMMCOMMONDTI. 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 DTI timing/synchronization unit
Monitoring Examples
No object names were sampled for this module, so specifics are inferred from the module description's split into status and configuration nodes. An admin would typically poll a DTI port's status object to confirm it is synchronized and receiving a valid timing reference, since a port reporting loss-of-signal or unlocked state would indicate the unit has fallen out of time sync, risking downstream clock drift on equipment relying on that DTI feed.
What Can Be Monitored
- DTI port operational status
- timing signal configuration
- DTI synchronization/lock state
