Description: MEGACO-RINGING-MIB module

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 MEGACO-RINGING-MIB?

MEGACO-RINGING-MIB is an IETF-related MIB tied to the Megaco/H.248 protocol used for controlling media gateways in VoIP and telephony networks, specifically covering ringing tone/signal handling. Given its narrow, package-specific scope, it is expected to expose configuration and status objects for ringing signal generation/detection on gateway terminations rather than broad system health data. It would primarily support monitoring of software-level signaling status, such as whether a ringing signal is currently active on a given termination, since no hardware environmental objects are implied by its name or scope. It depends on the base Megaco/H.248 MIB framework that defines the gateway, context, and termination objects it extends. It would typically be deployed on media gateways in carrier or enterprise VoIP infrastructure that need to signal or detect ringing tones on subscriber lines. Network engineers evaluating or troubleshooting this functionality can download the MEGACO-RINGING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in MEGACO-RINGING-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

VoIP media gateways
vendor-neutral, standards-based MIB, not tied to a specific manufacturer

Monitoring Examples

No sample objects were provided for this MIB, so no concrete monitoring scenario can be described with confidence; based on its name, it likely defines objects for configuring or reporting on ringing signal/tone packages used by Megaco/H.248 media gateway terminations.

What Can Be Monitored

ringing signal activation status
ringing tone/package configuration

mgcoRingingPatternTable	1.3.6.1.2.1.0.1.1.1		not-accessible	This table contains a list of the various Ringing Pattern Ids available on a Media Gateway. Each row of the table contains a field to indicate the Ringing Pattern Id value, a field to indicate the Cadence Group Id associated with the Ringing Pattern Id, a field to hold a name for the pattern
mgcoRingingPatternEntry	1.3.6.1.2.1.0.1.1.1.1		not-accessible	This entry contains objects that indicate the pattern Id value, the Cadence Group Id value, the pattern Name, and the status of the row. The indices for an entry is the mgcoRingingPatternId and a manager creates a row in this table to define a Ringing pattern.
INT mgcoRingingPatternId	1.3.6.1.2.1.0.1.1.1.1.1	INTEGER	not-accessible	A value to indicate a unique ringing pattern identity.
INT mgcoRingingCadenceGroupId	1.3.6.1.2.1.0.1.1.1.1.2	INTEGER	read-create	A value to indicate the entry in the mgcoRingingCadenceGroupTable that defines this ringing pattern, it is an Index into that table
STR mgcoRingingPatternName	1.3.6.1.2.1.0.1.1.1.1.3	DisplayString	read-create	A string to indicate a unique ringing pattern identity.
ROW mgcoRingingPatternRowStatus	1.3.6.1.2.1.0.1.1.1.1.4	RowStatus	read-create	This is used to create new rows in this table, modify existing rows, and to delete rows.
TES mgcoRingingCadenceNextGroupId	1.3.6.1.2.1.0.1.1.2	TestAndIncr	read-write	The Next Cadence Group Id value available for a Media Gateway. Assists the manager in selecting a value for mgcoRingingCadenceGroupTable. A manager will 'lock' this variable to ensure single access.
mgcoRingingCadenceGroupTable	1.3.6.1.2.1.0.1.1.3		not-accessible	This table contains a list of the various cadence groups. This table is recursively accessed in order to completely define a cadence
mgcoRingingCadenceGroupEntry	1.3.6.1.2.1.0.1.1.3.1		not-accessible	This entry contains objects that describe the cadence characteristics. The indices for an entry are the mgcoRingingCadenceGroupId and mgcoRingingCadenceGroupIndex. mgcoRingingCadenceGroupId is a field from the mgcoRingingPatternTable
INT mgcoRingingCadenceGroupIndex	1.3.6.1.2.1.0.1.1.3.1.1	INTEGER	not-accessible	A value used to access all the entries in the table that correspond to a particular Group Id. This value also serves to order the entries for the Group Index.
