Description: Extends standard ADSL line MIB objects with Paradyne-specific parameters for line provisioning and performance monitoring.

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 PDN-ADSL-LINE-EXT-MIB?

PDN-ADSL-LINE-EXT-MIB is a Paradyne (later Zhone Technologies) enterprise MIB supplementing the IETF standard ADSL-LINE-MIB and ADSL-LINE-EXT-MIB with additional objects needed for ADSL2/ADSL2+ modes not yet covered by the standard MIBs at the time it was written. It exposes per-line transceiver capability/configuration/actual-mode objects, power-management configuration including L0/L2 low-power states and timers, spectrum profile selection, and dynamic spectrum management (Ldsf) parameters. Its main monitoring role is DSL line performance and configuration health -- tracking which ADSL2/ADSL2+ transceiver mode a line is actually operating in, whether it is in a reduced-power L2 state and for how long, and whether the applied spectrum profile matches intended provisioning. It has an explicit stated dependency on the standard ADSL-LINE-MIB and ADSL-LINE-EXT-MIB, extending their per-line indexing to cover ADSL2/ADSL2+ specifics. It is typically deployed on Paradyne/Zhone DSLAM or ADSL2+ access equipment in telco central offices delivering broadband over copper, and the PDN-ADSL-LINE-EXT-MIB MIB extends the standard ADSL line MIBs to cover those ADSL2/ADSL2+-specific line states.

IPNetwork Monitor allows you to monitor SNMP objects defined in PDN-ADSL-LINE-EXT-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

Paradyne/Zhone ADSL2/ADSL2+ DSLAM
Paradyne/Zhone ADSL access equipment

Monitoring Examples

An operator polls pdnAdslLineExtTable/pdnAdslLineExtEntry, keyed by the standard ADSL line interface index, comparing pdnAdslLineTransAtucCap/Config/Actual to confirm the ATU-C transceiver negotiated the expected ADSL2+ mode rather than falling back to plain ADSL. Reading pdnAdslLinePmMode and pdnAdslLineL2Time reveals whether a line has dropped into the low-power L2 state and how long it has stayed there, affecting throughput. pdnAdslLineSpectrumProfile confirms the correct spectral mask is applied to avoid crosstalk, and pdnAdslLineExtNotifications would fire traps on related state changes.

What Can Be Monitored

ADSL2/ADSL2+ transceiver mode (capability/config/actual)
power management state (L0/L2)
spectrum profile
line power management timers
dynamic spectrum management (Ldsf) settings

How to Use in IPNetwork Monitor

Example using pdnAdslLineStatusAtucMaxAttainableLineRate OID:

Select a Paradyne/Zhone ADSL2/ADSL2+ DSLAM and access equipment as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type pdnAdslLineStatusAtucMaxAttainableLineRate into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The maximum downstream net data rate currently attainable by the ATU-C transmitter and the ATU-R receiver. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the value climbs close to a level you consider a practical ceiling for this device, since a rising peak often signals sustained load growth worth planning capacity around. Click Finish to create the monitor; you can adjust any parameter later.

pdnAdslLineExtMIB	1.3.6.1.4.1.1795.2.24.2.6.24			This MIB module is a supplement to the ADSL-LINE-MIB and to the ADSL-LINE-EXT-MIB, the `standard` MIBs, where additional objects are needed to support ADSL modes or flavors not covered in the `standard` MIBs. At the time this MIB was defined, the IETF ADSL MIB Working does not have any work on the 'standard' MIBs planned and/or has not produced a schedule to address ADSL2/ADSL2plus needs. As a result, these objects may be a `temporary' solution until MIBs/Objects are defined or extended to meet the needs of ADSL2/ADSL2plus. The following documents that should be referenced with respect to this MIB: [G.997.1] ITU-T G997.1 `Physical layer management for Digital Subscriber Line (DSL) transceivers', May 2003. [G.991.1 Am 1] ITU-T-G997.1 Amendment 1 `Physical layer management for Digital Subscriber Line (DSL) transceivers Amendment 1', December 2003.

pdnAdslLineExtNotifications	1.3.6.1.4.1.1795.2.24.2.6.24.0
pdnAdslLineExtObjects	1.3.6.1.4.1.1795.2.24.2.6.24.1
pdnAdslLineExtTable	1.3.6.1.4.1.1795.2.24.2.6.24.1.1		not-accessible	This table extends the adslLineTable in support of an ADSL Line object. The objects pdnAdslLineTransAtucCap, pdnAdslLineTrans- AtucConfig, and pdnAdslLineTransAtucActual exist along with their PdnAdslTransmissionModeType TC because the AdslTransmissionModeType defined in the ADSL-LINE-EXT-MIB does not include the ADSL2/ADSL2plus bits defined in ITU G.997.1 (05/2003) ATU Transmission System Enabling (ATSE) section. When using the objects defined in this MIB with a syntax of type PdnAdslTransmissionModeType, the interworking relationship between these objects and the objects defined in the ADSL-LINE- EXT-MIB defined with a syntax of type AdslTransmissionModeType must be considered and explained in an implementation-specific document such as an Operational Specification. Note that the PdnAdslTransmissionModeType is a super set of the AdslTransmis- sionModeType. One possible implementation could be as follows: 1. Both objects of syntax AdslTransmissionModeType defined in the ADSL-LINE-EXT-MIB and objects of syntax PdnAdsl- TransmissionModeType defined in this MIB are supported. By supporting both, a manager with the ADSL-LINE-EXT-MIB loaded could manage the device with the restriction of not being able to utilize ADSL2/ADSL2plus modes. 2. When the ADSL2/ADSL2plus capabilities are desired, a manager would have to use the objects defined in this MIB to configure the transmission modes, read capability, or read the actual transmission mode of the ATU-C. 3. The transmission mode that the ATU-C is currently configured for is based on the last object, adslLineTrans- AtucConfig or pdnAdslLineTransAtucConfig, that was written.
pdnAdslLineExtEntry	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1		not-accessible	An extended entry in the adslLineTable.
PDN pdnAdslLineTransAtucCap	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.1	PdnAdslTransmissionModeType	read-only	The transmission modes, represented by a bitmask that the ATU-C is capable of supporting. The modes available are limited by the design of the equipment.
PDN pdnAdslLineTransAtucConfig	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.2	PdnAdslTransmissionModeType	read-write	The transmission modes, represented by a bitmask, currently enabled by the ATU-C. The manager can only set those modes that are supported by the ATU-C. An ATU-C's supported modes are provided by pdnAdslLineTransAtucCap.
PDN pdnAdslLineTransAtucActual	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.3	PdnAdslTransmissionModeType	read-only	The actual transmission mode of the ATU-C. During ADSL line initialization, the ADSL Transceiver Unit Remote terminal end (ATU-R) will determine the mode used for the link. This value will be limited a single transmission mode that is a subset of those modes enabled by the ATU-C and denoted by pdnAdslLineTransAtucConfig. After an initialization has occurred, its mode is saved as the `Current' mode and is persistent should the link go down. This object returns 0 (i.e. BITS with no mode bit set) if the mode is not known.
INT pdnAdslLinePowerManagementConfig	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.4	INTEGER	read-write	This object enables or disables power management functionality.
STR pdnAdslLineSpectrumProfile	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.5	SnmpAdminString	read-write	The value of this object identifies the row in the ADSL Line Spectrum Profile Table, pdnAdslLineSpectrumProfileTable, which applies for this ADSL line. If this object is not a zero-length string, it should default to the default profile whose name is `DEFVAL'.
BIT pdnAdslLinePmMode	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.6	Bits	read-write	The line states the ATU-C or ATU-R may autonomously transition to on this line. It is coded in a bit-map representation (0 if not allowed, 1 if allowed) as follows: idleStateL3(0) - Bit 0 L3 state (Idle state) lowPwrStateL1L2(1) - Bit 1 L1/L2 state (Low power state)
U32 pdnAdslLineL0Time	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.7	Unsigned32	read-write	The minimum time, in seconds, between and Exit from the L2 state and the next Entry into the L2 state.
U32 pdnAdslLineL2Time	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.8	Unsigned32	read-write	The minimum time, in seconds, between an Entry into the L2 state and the first Power Trim in the L2 state and between two con- secutive Power Trims in the L2 State.
U32 pdnAdslLineL2Atpr	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.9	Unsigned32	read-write	The maximum aggregate transmit power reduction, in dB, that can be performed through a single Power Trim in the L2 state. At the time this MIB was produced, the upper limit for this object was not updated in the G.997.1 with respect to ADSL2plus. As such, the upper limit of this object should be defined in an implementation- specific document such as an Operational Specification.
INT pdnAdslLineLdsf	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.10	INTEGER	read-write	Defines whether the line should be forced into the loop diagnostics mode by the near-end ATU on this line. ldsfMode0(1) - 0: Inhibits the near-end ATU from performing loop diagnostics mode procedures on the line. Loop diagnostic mode procedures may still be initiated by the far-end ATU. ldsModef1(2) - 1: Forces the near-end ATU to perform the loop diagnostics procedures. The line needs to be forced to the L3 state (idle state) before it can be forced to the loop diagnostics mode. Only while the line power management state is the L3 state, the line can be forced into the loop diagnostics mode procedures. The following are ways to force the line to the L3 state: (1) Set the ifAdminStatus to down. When the loop diagnostics mode procedures are completed successfully, this object shall reset to ldsf0 and the line shall return to and remain in the L3 idle state. The loop diagnostics data shall be available at least until the line is forced to the L0 state. If the loop diagnostics procedures can't be completed successfully, then an Initialization Failure occurs. As long as loop diagnostics procedures are not completed successfully, attempts shall be made to do so, until the loop diagnostics mode is no longer forced on the line through this configuration parameter.
U32 pdnAdslLineL2Atprt	1.3.6.1.4.1.1795.2.24.2.6.24.1.1.1.11	Unsigned32	read-write	This parameter represents the total maximum aggregate transmit power reduction (in dB) that can be performed in an L2 state. This is the sum of all reductions of L2 Request (i.e., at transition of L0 to L2 state) and Power Trims.

pdnAdslLineSpectrumProfileEntry	1.3.6.1.4.1.1795.2.24.2.6.24.1.2.1		not-accessible	Each entry contains a specific profile for transmission spectrum and power spectral density related parameters. A default profile with an index of `DEFVAL', will always exist and its parameters will be set to vendor or product specific values, unless otherwise specified in this document.
STR pdnAdslLineSpectrumProfileName	1.3.6.1.4.1.1795.2.24.2.6.24.1.2.1.1	SnmpAdminString	not-accessible	This object identifies a row in the pdnAdslLineSpectrumProfile- Table. The system will always provide a default profile whose name is `DEFVAL'.
ROW pdnAdslLineSpectrumProfileRowStatus	1.3.6.1.4.1.1795.2.24.2.6.24.1.2.1.2	RowStatus	read-create	This object is used to create a new row or modify or delete an existing row in this table. A profile is activated by setting this object to `valid'. Before a profile can be deleted or taken out of service, by setting this object to `destroy' or `outOfService', the profile must be first unreferenced from all entries that referred to it (entries in the pdnAdslLineExtTable).
STR pdnAdslLineSpectrumModeSpecificPsdProfile	1.3.6.1.4.1.1795.2.24.2.6.24.1.2.1.3	SnmpAdminString	read-create	The value of this object identifies the row(s) in the ADSL Mode-Specific PSD Configuration Table, pdnAdslModeSpecific- PsdConfTable, which applies for this Line Spectrum Profile. A particular ADSL line may need to support multiple mode- specific power spectral density related settings. For example, a ADSL line may need to support one set of settings for ADSL2 and another set of settings for ADSL2plus. See the pdnAdslMode- SpecificPsdConfTable for additional detail. The system will always provide a default profile whose name is `DEFVAL'
STR pdnAdslLineSpectrumAtucCarMaskProfile	1.3.6.1.4.1.1795.2.24.2.6.24.1.2.1.4	SnmpAdminString	read-create	This object identifies one or more rows in the pdnAdslCarMaskTable. The pdnAdslCarMaskTable is a table containing a list of subcarriers to be masked in the downstream or upstream direction; the profile in the pdAdslCarMaskTable that this object identifies will apply the masks in the downstream direction. This object defaults to an empty string meaning that no subcarriers are masked by an administrator.
STR pdnAdslLineSpectrumAturCarMaskProfile	1.3.6.1.4.1.1795.2.24.2.6.24.1.2.1.5	SnmpAdminString	read-create	This object identifies one or more rows in the pdnAdslCarMaskTable. The pdnAdslCarMaskTable is a table containing a list of subcarriers to be masked in the downstream or upstream direction; the profile in the pdAdslCarMaskTable that this object identifies will apply the masks in the upstream direction. This object defaults to an empty string meaning that no subcarriers are masked by an administrator.
pdnAdslModeSpecificPsdConfTable	1.3.6.1.4.1.1795.2.24.2.6.24.1.3		not-accessible	This table binds an entry indexed by a specific ADSL type or flavor (e.g. ADSL2 or ADSL2+) and indexed by a profile name to a specific DSL PSD Configuration Profile.
pdnAdslModeSpecificPsdConfEntry	1.3.6.1.4.1.1795.2.24.2.6.24.1.3.1		not-accessible	An entry in the table. For each particular ADSL mode or flavor supported (pdnAdslMOdeSpecificPsdConfAdslMode), there will be an entry that points to an entry in the ADSL PSD Configuration Table (pdnAdslPsdConfTable). For example, if ADSL2 and ADSL2plus ADSL modes are supported, this table will have the following two default entries: 1. An entry indexed by pdnAdslModeSpecificPsd- ConfProfileName = 'DEFVAL' and pdnAdslModeSpecific- PsdConfAdslMode = adsl2(1) and has pdnAdslModeSpecific- PsdConfAdslPsdConfProfile = DEFVAL_ADSL2 2. An entry indexed by pdnAdslModeSpecificPsd- ConfProfileName = 'DEFVAL' and pdnAdslModeSpecific- PsdConfAdslMode = adsl2plus(3) and has pdnAdslModeSpecific- PsdConfAdslPsdConfProfile = DEFVAL_ADSL2PLUS DEFVAL entries may be modified but not deleted.

STR pdnAdslModeSpecificPsdConfAdslPsdConfProfile	1.3.6.1.4.1.1795.2.24.2.6.24.1.3.1.4	SnmpAdminString	read-create	This object identifies a row in the ADSL PSD Configuration Table, pdnAdslPsdConfTable.
pdnAdslPsdConfTable	1.3.6.1.4.1.1795.2.24.2.6.24.1.4		not-accessible	This table contains power spectral density settings.
pdnAdslPsdConfEntry	1.3.6.1.4.1.1795.2.24.2.6.24.1.4.1		not-accessible	Each entry contains specific power spectral density settings for a particular profile. A default profile for each particular ADSL mode or flavor supporting PSD configuration will exist (See the pdnAdslModeSpecificPsdConfAdslMode object the the range of possible ADSL modes or flavors that are possible). For example, if only ADSL2 and ADSL2plus modes are supported, the indices would be 'DEFVAL_ADSL2' and 'DEFVAL_ADSL2PLUS'. The DEFVAL rows may be modified but not deleted. The DEFVAL rows will always exist and its parameters will be set to vendor or product specific values, unless otherwise specified in this document.
