H3C-E1T1VI-MIB

Description: H3C MIB for E1/T1 voice interface management including channelization, signaling, and voice port configuration.

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.

H3C-E1T1VI-MIB is an H3C private-enterprise MIB for E1/T1 voice interface (VI) management, covering channelized voice trunk ports carrying TDM telephony over E1/T1 lines, information not covered by the standard RFC 1213/RFC 2233 interface MIBs. It exposes timeslot utilization data per interface, including the number of timeslots in use and the utilization ratio, along with trap-enable configuration for timeslot-related events. Its monitoring focus is capacity/performance status of voice trunk hardware: an operator sees how much of a voice interface's available timeslot capacity is consumed and receives traps when a threshold-worthy condition occurs. It complements standard telecom interface MIBs and IF-MIB extensions since it layers voice-channel semantics on top of the underlying physical E1/T1 interface. Deployment context is H3C voice gateways/routers with E1/T1 voice interface cards used for TDM voice trunking between PBXs and IP telephony infrastructure, typically after an H3C-E1T1VI-MIB download is loaded into the operator's MIB browser.

An administrator polls h3cE1T1VITable/h3cE1T1VIEntry for h3cE1T1VIUsingTimeslots and h3cE1T1VIUsingTimeslotsRatio to see how heavily a voice trunk's available timeslots are utilized. As utilization nears full capacity, new calls may start failing, so enabling h3cE1T1VITrapTimeSlotEnable ensures objects under h3cE1T1VINotifications fire a trap so the operator is alerted before the trunk runs out of usable timeslots.
