The table adsl2SCStatusTable contains status parameters of the ADSL2 sub-carriers. The following points apply to this table: 1. The main purpose of this table is to hold the results of a DELT. 2. This table also holds parameters obtained at line initialization time. 3. The rows in this table are volatile; that is, they are lost if the SNMP agent is rebooted. 4. Due to the large OCTET STRING attributes in this table, the worst case memory requirements for this table are very high. The manager may use the row status attribute of this table to delete rows in order to reclaim memory. 5. The manager may create rows in this table. The SNMP agent may create rows in this table. Only the manager may delete rows in this table. 6. The maximum number of rows allowable in this table is indicated by the scalar attribute adsl2ScalarSCMaxInterfaces. The number of rows available in this table is indicated by the scalar attribute adsl2ScalarSCAvailInterfaces. 7. The SNMP agent is permitted to create rows in this table when a DELT completes successfully or when line initialization occurs. It is not mandatory for the SNMP agent to create rows in this table; hence, it may be necessary for the manager to create rows in this table before any results can be stored. 8. If the manager attempts to create a row in this table and there are no more rows available, the creation attempt will fail, and the response to the SNMP SET PDU will contain the error noCreation(11). 9. If the SNMP agent attempts to create a row in this table and there are no more rows available, the creation attempt will fail, and the attribute adsl2LineCmndConfLdsfFailReason will indicate the reason for the failure. The failure reason will be either tableFull(10) or noResources(11). 10. An example of use of this table is as follows: Step 1. : The DELT is started by setting the : adsl2LineCmndConfLdsf from inhibit to force. Step 2. : The DELT completes, and valid data is : available. Step 3. : The row in the adsl2SCStatusTable where the : results will be stored does not yet exist so : the SNMP agent attempts to create the row. Step 4. : Due to a low memory condition, a row in the : adsl2SCStatusTable table cannot be created at : this time. Step 5. : The reason for the failure, tableFull(10), is : indicated in the adsl2LineCmndConfLdsfFailReason : attribute. 11. Another example of use of this table is as follows : Step 1. : The DELT is started by setting the : adsl2LineCmndConfLdsf from inhibit to force. Step 2. : The DELT completes and valid data is : available. Step 3. : The row in the adsl2SCStatusTable where the : results will be stored does not yet exist so : the SNMP agent attempts to create the row. Step 4. : The row creation is successful. Step 5. : The value of the attribute : adsl2LineCmndConfLdsfFailReasonreason is set : to success(2). 12. Another example of use of this table is as follows: Step 1. : The manager creates a row in adsl2SCStatusTable : for a particular ADSL2 line. Step 2. : The DELT is started on the above-mentioned : line by setting the adsl2LineCmndConfLdsf from : inhibit to force. Step 3. : The DELT completes, and valid data is : available.

When a row in the adsl2LineConfProfTable table (the parent row) is created, the SNMP agent will automatically create a 'mandatory' row in this table. When the parent row is deleted, the SNMP agent will automatically delete all associated rows in this table. Any attempt to delete the 'mandatory' row using the adsl2LConfProfModeSpecRowStatus attribute will be rejected by the SNMP agent. The manager MAY create an 'optional' row in this table using the adsl2LConfProfModeSpecRowStatus attribute if the parent row exists. The manager MAY delete an 'optional' row in this table using the adsl2LConfProfModeSpecRowStatus attribute at any time. If the actual transmission mode of a DSL line does not match one of the 'optional' rows in this table, then the line will use the PSD configuration from the 'mandatory' row. Entries in this table MUST be maintained in a persistent manner.

OBJECT-TYPE

The table adsl2LineConfProfModeSpecTable extends the ADSL2 line configuration profile by ADSL Mode Specific parameters.

OBJECT-TYPE

The ADSL Mode is a way of categorizing the various ADSL transmission modes into groups; each group (ADSL Mode) shares the same PSD configuration. There should be multiple entries in this table for a given line profile in case multiple bits are set in adsl2LConfProfAtuTransSysEna for that profile.

OBJECT-TYPE

OBJECT-TYPE

The maximum nominal transmit PSD in the upstream direction during initialization and Showtime. It ranges from -600 to -300 units of 0.1 dBm/Hz (physical values are -60 to -30 dBm/Hz).

OBJECT-TYPE

The maximum nominal aggregate transmit power in the downstream direction during initialization and Showtime. It ranges from 0 to 255 units of 0.1 dBm (physical values are 0 to 25.5 dBm).

OBJECT-TYPE

The maximum nominal aggregate transmit power in the upstream direction during initialization and Showtime. It ranges from 0 to 255 units of 0.1 dBm (physical values are 0 to 25.5 dBm).

OBJECT-TYPE

The maximum upstream aggregate receive power over the relevant set of sub-carriers. The ATU-C should verify that the upstream power cutback is such that this maximum aggregate receive power value is honored. It ranges from -255 to 255 units of 0.1 dBm (physical values are -25.5 to 25.5 dBm). A value of 0x7FFFFFFF (2147483647) means that there is no limit.

OBJECT-TYPE

The downstream PSD mask applicable at the U-C2 reference point. This parameter is used only for G.992.5, and it may impose PSD restrictions (breakpoints) in addition to the Limit PSD mask defined in G.992.5. This is a string of 32 pairs of values in the following structure: Octets 0+1 - Index of 1st sub-carrier used in the context of a first breakpoint. Octet 2 - The PSD reduction for the sub-carrier indicated in octets 0 and 1. Octets 3-5 - Same, for a 2nd breakpoint. Octets 6-8 - Same, for a 3rd breakpoint. This architecture continues until octets 94-95, which are associated with a 32nd breakpoint. Each subcarrier index is an unsigned number in the range 1 to NSCds. Each PSD reduction value is in the range 0 (0dBm/Hz) to 255 (-127.5dBm/Hz) with steps of 0.5dBm/Hz. Valid values are in the range 0 to 190 (0 to -95dBm/Hz). When the number of breakpoints is less than 32, all remaining octets are set to the value 0. Note that the content of this object should be correlated with the sub-carriers mask and with the RFI setup.

Octet 2 - The PSD reduction for the sub-carrier indicated in octets 0 and 1. Octets 3-5 - Same, for a 2nd breakpoint. Octets 6-8 - Same, for a 3rd breakpoint. This architecture continues until octets 9-11, which are associated with a 4th breakpoint. Each subcarrier index is an unsigned number in the range 1 to NSCus. Each PSD reduction value is in the range 0 (0dBm/Hz) to 255 (-127.5dBm/Hz) with steps of 0.5dBm/Hz. Valid values are in the range 0 to 190 (0 to -95dBm/Hz).
