What Is ZhoneAAL2-MIB?
ZhoneAAL2-MIB is a Zhone Technologies enterprise MIB implementing the ATM Adaptation Layer 2 (AAL2) MIB, covering configuration and performance statistics for AAL2 circuits carrying voice traffic over ATM (Voice over ATM) on Zhone access equipment. It exposes configuration objects for AAL2 circuit/channel setup and performance counters tracking cell/packet statistics on those circuits. Its primary monitoring value is around software/circuit-level performance rather than physical hardware sensors: administrators track AAL2 channel performance statistics (error counts, utilization) to ensure voice quality is maintained over ATM transport. It builds on the standard ATM-MIB (RFC 2515) and AAL2 signaling conventions, since AAL2 circuits are carried over underlying ATM virtual connections defined by those standards. It is deployed on Zhone ATM-based access/aggregation platforms in legacy carrier networks still carrying voice traffic over ATM infrastructure, such as DSLAMs or multiservice access nodes with voice gateway functions, where ZhoneAAL2-MIB SNMP monitoring helps catch voice-quality degradation early.
IPNetwork Monitor allows you to monitor SNMP objects defined in ZhoneAAL2-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
- Zhone ATM access/aggregation platform
Monitoring Examples
No sample objects were provided in the source data, but a MIB of this kind would typically expose an AAL2 circuit/channel table with per-circuit performance counters for cell loss, errored seconds, or channel utilization. An administrator would poll these counters to detect degraded voice quality on a given AAL2 channel, correlating rising error counts with subscriber complaints of choppy or dropped calls.
What Can Be Monitored
- AAL2 circuit/channel configuration
- AAL2 performance/error counters
- channel utilization

| zhoneAtmAAl2 | 1.3.6.1.4.1.5504.4.2.1 | ATM Adaptation Layer 2 (AAL2) MIB | ||
| aal2Traps | 1.3.6.1.4.1.5504.4.2.1.0 | Traps for the AAL2 MIB. | ||
| NTF aal2ExternalAIS | 1.3.6.1.4.1.5504.4.2.1.0.1 | Alarm Indication Signal - a signal, associated with a maintenance alarm detected on a defective maintenance span, that is transmitted in the direction of the defect as a substitute for the normal signal. Its purpose is to show downstream entities that a defect has been identified, so that other maintenance alarms consequent to this first defect can be inhibited. The external bit stream representation of AIS may be an all 1s signal. | ||
| NTF aal2ExternalRAI | 1.3.6.1.4.1.5504.4.2.1.0.2 | Remote Alarm Indication - a signal transmitted upstream from a terminal that has detected defects persisting long enough to constitute a received signal failure. Its purpose is to report in the backward direction that there is an interruption of service in the forward direction. | ||
| NTF aal2InternalAIS | 1.3.6.1.4.1.5504.4.2.1.0.3 | Alarm Indication Signal - a signal transmitted in the downstream direction from the AAL type 2 connecting point that first detects a defect affecting the AAL type 2 connection; this includes defects indicated by lower layers. | ||
| NTF aal2InternalRDI | 1.3.6.1.4.1.5504.4.2.1.0.4 | Remote Defect Indication - a signal transmitted upstream by an AAL type 2 endpoint that is in an alarm state as the result of having received an AAL type 2 connection AIS or having detected a defect that affects the AAL type 2 connection. | ||
| NTF aal2PvcDown | 1.3.6.1.4.1.5504.4.2.1.0.5 | Indicates the the status of the PVC has gone down. | ||
| NTF aal2PerfCellLossThreshTrap | 1.3.6.1.4.1.5504.4.2.1.0.6 | This trap is generated when the number of Bad Sequence errors exceeds the aal2AlarmConfigThreshCellLoss for a 15-minute interval. A bad sequence error is detected when some cells have been lost. | ||
| NTF aal2PerfCongestionThreshTrap | 1.3.6.1.4.1.5504.4.2.1.0.7 | This trap is generated when the number of congestion events exceeds the aal2AlarmConfigThreshCongestion for a 15-minute interval. | ||
| NTF aal2ElcpIgOperStatusChange | 1.3.6.1.4.1.5504.4.2.1.0.8 | A notification is sent when the operational status of an ELCP interface group changes. | ||
| aal2VclTable | 1.3.6.1.4.1.5504.4.2.1.1 | not-accessible | The AAL2 Virtual Channel Link (VCL) Table This table contains configuration and state information of a bi-directional AAL2 Virtual Channel Link (VCL) at an ATM interface. Each VCL entry has an associated Connection Identifier (CID) table, comprised of one or more CID entries. Each VCL entry refers to an Audio Profile (AP) by type (pre-defined or user-defined) and index into an AP table. An AAL2 VCL entry is created by the agent when an RFC2515 (ATM-MIB) atmVclEntry of atmVccAalType 2 is created. Objects in the row entry can by modified by CLI or ZMS if the connection is down. Deletion of AAL2 VCL entries is controlled by the rfc2515 (ATM-MIB) atmVclRowStatus. | |
| aal2VclEntry | 1.3.6.1.4.1.5504.4.2.1.1.1 | not-accessible | An entry in the AAL2 Virtual Channel Link (VCL) Table. Indexed by ifIndex, atmVclVpi from atmVclTable, and atmVclVci from atmVclTable. An AAL2 VCL entry or row (aal2VclEntry) is 'automatically' created by the agent when an rfc2515 (ATM-MIB) atmVclEntry with atmVccAalType 2 is created. The request to create an RFC2515 atmVclEntry can originate at either CLI or ZMS. Once the row exists, objects within the row with read-write access can by modified by CLI or ZMS if the connection is down. Deletion of an aal2VclEntry is managed by the rfc2515 (ATM-MIB) atmVclRowStatus. Note there is no RowStatus in the aal2VclEntry, whereas there is an atmVclRowStatus in the rfc2515 atmVclEntry. | |

If the field atmVccAal2AppId is set to casPotsOnlyNoElcp then the valid range for aal2VclMinCidForAal2UserChannels and aal2VclMinCidForAal2UserChannels is between 16 and 128. If the field atmVccAal2AppId is set to dss1BriOnlyNoElcp then the valid range for aal2VclMinCidForAal2UserChannels and aal2VclMinCidForAal2UserChannels is between 129 and 223. Also the aal2VclMaxCidForAal2UserChannels must be greater than aal2VclMinCidForAal2UserChannels. For Jetstream app-id, this Cid value represents the port number which the phone is on and the valid range is 1 to 254. The range for non-Jetstream applications is 16 to 255. By default because atmVccAal2AppId is set to casPotsOnlyNoElcp the default value of this field is 16. |
| I32 aal2VclMaxCidForAal2UserChannels | 1.3.6.1.4.1.5504.4.2.1.1.1.9 | Integer32 | read-write | Maximum CID value for AAL2 user channels. Valid range is 1..255. Maximum CID is 255. If the field atmVccAal2AppId is set to casPotsOnlyNoElcp then the valid range for aal2VclMinCidForAal2UserChannels and aal2VclMinCidForAal2UserChannels is between 16 and 128. If the field atmVccAal2AppId is set to dss1BriOnlyNoElcp then the valid range for aal2VclMinCidForAal2UserChannels and aal2VclMinCidForAal2UserChannels is between 129 and 223. Also the aal2VclMaxCidForAal2UserChannels must be greater than aal2VclMinCidForAal2UserChannels. For Jetstream app-id, this Cid value represents the port number which the phone is on and the valid range is 1 to 254. The range for non-Jetstream applications is 16 to 255. By default because atmVccAal2AppId is set to casPotsOnlyNoElcp the default value of this field is 127. |
| I32 aal2VclNextCid | 1.3.6.1.4.1.5504.4.2.1.1.1.10 | Integer32 | read-only | The Channel Identifier is one of the indicies for the CID table, aal2CidTable. The Application Identifier, atmVccAal2AppId, determines the valid range of values for the aal2Cid. The next CID, aal2VclNextCid, indicates the next valid aal2Cid that can be used to create a new row in the aal2CidTable. A value of 0 indicates that an aal2Cid is not available for a given atmVccAal2AppId. The agent manages this value. Range of valid values is 0, 16..255. Also see the description for aal2Cid. |
| I32 aal2VclTimerCU | 1.3.6.1.4.1.5504.4.2.1.1.1.11 | Integer32 | read-write | Value of the 'combined use' Timer_CU. The combined use Timer_CU assures that CPS-Packets with one or more octets already packed, wait at most the duration of Timer_CU before being scheduled for transmission (actual transmission takes place after receipt of a MAAL_SEND.request primitive from Layer Management). |

| INT aal2VclCircuitModeData | 1.3.6.1.4.1.5504.4.2.1.1.1.13 | INTEGER | read-write | The service provided is the transfer of circuit mode data. The circuit mode data service is an emulation of the N*64 kbit/s (N = 1, 2, ..., 30) unrestricted, 8 kHz structured circuit mode service of Recommendations I.231.1 and I.231.10. The value N = 31 is also allowed. The value of N does not change during the lifetime of a call. Valid values are enabled and disabled. |
| INT aal2VclFrameModeData | 1.3.6.1.4.1.5504.4.2.1.1.1.14 | INTEGER | read-write | Frame mode data is an intermittent data stream containing delimited units of information, possibly of varying size, with idle intervals between them. The service provided is the transport of data units as specified in the Transmission Error Detection service of Recommendation I.366.1. There is no assurance of data unit delivery, but if delivered, the relative sequence and the bit integrity of data units are assured. This service corresponds to the service provided by the Common Part of AAL type 5, Recommendation I.363.5, except that the option of corrupted data delivery is not available.

Significance to peer-to-peer. The maximum size of an SSSAR-SDU may be restricted on a per SSSAR-connection basis with the parameter 'Max_SDU_Length'. This parameter is negotiated by signalling or management procedures. Valid values are 1..65568. |
| I32 aal2VclRasTimer | 1.3.6.1.4.1.5504.4.2.1.1.1.24 | Integer32 | read-write | The reassembly timer RAS_Timer assures that the reassembly of an SSSAR-SDU does not exceed a certain time; if such timer supervision is not required, the timer is disabled by setting the timer value to 0. If the timer is exceeded the i366.1 receive state machine goes into the abort state, look for the end of the frame and goes back to idle. See figure 8.1 I.366.2 State transition diagram. The default is 0 milliseconds. Value of 0 means the timer is disabled. |
| G32 aal2VclCellsReceived | 1.3.6.1.4.1.5504.4.2.1.1.1.25 | Gauge32 | read-only | Total cells received |
| G32 aal2VclCellsSent | 1.3.6.1.4.1.5504.4.2.1.1.1.26 | Gauge32 | read-only | Total cells sent |
| I32 aal2VclStatsTimeElapsed | 1.3.6.1.4.1.5504.4.2.1.1.1.27 | Integer32 | read-only | The number of seconds that have elapsed since the beginning of the current collection period. If, for some reason, such as an adjustment in the system's time-of-day clock, the current interval exceeds the maximum value, the agent will return the maximum value. |
| aal2CidTable | 1.3.6.1.4.1.5504.4.2.1.2 | not-accessible | The AAL2 Channel Identifier (CID) Table The AAL2 Channel Identifier Table contains status, I.366.2 SSCS parameters, and I.366.1 SSCS parameters for the channel identifier. Default values for these objects are defined in the AAL2 VCL entry. Values in the AAL2 Channel Identifier entry can supercede the defaults specified in the AAL2 VCL entry. The maximum number of connections or CIDs allowed per ATM VCL is 255. Certain atmVccAal2AppID values (ie, any app running over Common Channel Signaling) can cause the auto-creation of an AAL2 CID entry. When the creation of an AAL2 VCL entry does not lead to the auto-creation of an AAL2 CID entry by the agent, a CLI or ZMS request from the CLI or ZMS can use the AAL2 CID entry RowStatus object, aal2CidRowStatus, to create an aal2CidEntry instance. In this case, an rfc2515 (ATM-MIB) atmVclEntry must exist prior to creating an AAL2 CID entry. AAL2 CID entry deletion is accomplished with the AAL2 CID entry RowStatus object, aal2CidRowStatus. If an AAL2 VCL entry is deleted, then the agent cleans up all associated AAL2 CID entries. | |
| aal2CidEntry | 1.3.6.1.4.1.5504.4.2.1.2.1 | not-accessible | An entry in the Channel Identifier (CID) table. Indexed by ifIndex, atmVclVpi from atmVclTable, atmVclVci from atmVclTable, and aal2Cid. | |
| I32 aal2Cid | 1.3.6.1.4.1.5504.4.2.1.2.1.1 | Integer32 | not-accessible | The Channel Identifier is one of the indices for the CID table. The maximum number of connections allowed per ATM VCL is 255. Note that there are restrictions in the use of CID and in order to be LES compliant. The following assignments of AAL2 Channels and CID Allocation are specified in STR-VMOA-LES-01-00, Section 4.4. 0 Not used 1-7 Reserved for I.363.2 layer management 8 Some CPE manufactures use this CID for CCS and/or Emulated Loop Control protocol 9 If LES-EOC is supported, else not used. 10-15 for future revisions of STR-VMOA-LES-01-00 16-223 Bearer channels and ISDN D-channels 224-255 set aside for vendor-specific usage See STR-VMOA-LES-01-00 4.4 for allocation of CIDs when ELCP is not used, allocation of CIDs when ELCP is used, and implementation options for AAL2 CPS. If the ELCP is not used, the default assignment of CIDs to bearer channels and ISDN D-channels shall be as specified in this section. These default assignments may be overridden by provisioning or by management action. POTS ports at the CP-IWF shall be numbered from 1 to N, where N is the number of POTS ports that exist at the CP-IWF. CID = 16 shall be assigned to POTS port number 1, CID = 17 shall be assigned to POTS port number 2, and so on up to POTS port number N. For Jetstream applications, CID refers to port number and the valid range is 1 to 255. For non-Jetstream applications, the valid range is 16 to 255. |
