PDN-ADSL-LINE-EXT-MIB: View SNMP OID List / Download MIB

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.

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.

An extended entry in the adslLineTable.

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.

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.

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.

This object enables or disables power management functionality. Enumeration: 'disabled': 2, 'enabled': 1.

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'.

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) Bits: 'lowPwrStateL1L2': 1, 'idleStateL3': 0.

The minimum time, in seconds, between and Exit from the L2 state and the next Entry into the L2 state.

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.

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.

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. Enumeration: 'ldsfMode1': 2, 'ldsfMode0': 1.

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.

This table contains specific configuration of transmission spectrum and power spectral density related parameters that can be mapped to one of the ADSL lines.

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.

This object identifies a row in the pdnAdslLineSpectrumProfile- Table. The system will always provide a default profile whose name is `DEFVAL'.

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).

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'

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.

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 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.

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.
