The tables defined by this MIB module contain a collection of managed objects that are general in nature and apply to different types of modems. The structure of this module
resembles the ADSL-LINE-MIB, CISCO-SDSL-LINE-MIB,
ADSL-DMT-LINE-MIB, CISCO-ADSL-DMT-LINE-MIB, etc. Observe that the tables in this module do not necessarily extend the tables defined by the these mibs. Currently, only the table that contains the configuration information extends the profile tables defined by the above modules.
Mib objects must fulfill the following criteria to be contained in this mib module:
1) The ADSL-LINE-MIB or the modem specific mibs such as
CISCO-SDSL-LINE-MIB, CISCO-ADSL-DMT-LINE-MIB, etc. does not already contain a managed object representing the same information.
2) The mibs object must NOT be technology dependent, they must apply to various types of DSL modems, e.g. IDSL, SDSL, ADSL, etc.

InterfaceIndexA unique value, greater than zero, for each interface or interface sub-layer in the managed system. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization.

Represents status of the test per port. Once a test is completed or aborted, the status remains at passed, failed, or aborted until user clears it by setting cXdslTestTrigger to clear or starts a new test. This object will return 'passed' if there are no cXdslTestBertErrors and no cXdslTestBertBitErrors
The type of test to be performed. The test duration is determined by cXdslTestTime. All the test types inhibit the service on that line. The agent will only change cXdslTestType, if no test is active on the targeted port. The XTU-C may support other test types that are not defined in this mib, if such test is running this object will have a value of 'other'. cXdslTestTrigger will start the test when set to start.
Starts, stops (aborts) a test in progress or clears the test results. The agent will only start a new test, if no test is active on the targeted port. The value of this object returns 'ready' when read, the value cannot be set to 'ready'. The cXdslTestTrigger value affects cXdslTestStatus as following:
value current TestStatus --> new TestStatus
----- ------------------ --------------
start inactive/pass/fail/ active
aborted
stop active aborted
clear pass/fail/aborted inactive
All other combinations will result in error, for instance, starting a test may fail due to a test already in progress. Likewise, stopping a test NOT in progress will result in an error.
The value of cXdslTestType, cXdslTestStatus and cXdslTestTime will remain in the system until cleared or until the the agent is reset. When this object is set to 'clear' the test results are cleared, cXdslTestType is set to none and cXdslTestStatus is set to inactive. The 'old' test results will remain until completion of a 'new' test if test results are not cleared

Note: that even if there are no BERT errors the test can still fail due to BertBitErrors.

This table contains enterprise-specific mode parameters initiated by the XTU-C class devices supported by the system.
InterfaceIndexA unique value, greater than zero, for each interface or interface sub-layer in the managed system. It is recommended that values are assigned contiguously starting from 1.

The value of this object specifies the loopback mode of this interface. The interface will stay in loopback mode until this object is set to disabled. The XTU-C may support other mode types that are not defined in this mib, if such mode is running, this object will have a value of 'other'. The loopback modes will inhibit the service on that line.
The value of this object specifies the spectrum mode of this interface. The interface will stay in spectrum mode until this object is set to disabled. The modes will inhibit the service on that line. Not all spectrum modes are avaiable for all types of modems. The modes translate as follows:
sdsl & shdsl ------------
spectrum1 = tx-1 spectrum2 = tx-3
spectrum3 = tx+1 spectrum4 = tx+3
spectrum5 = spec2PT spectrum6 = spec4PT
dmt ---
spectrum1 = reverb spectrum2 = medley
spectrum3 = pilot spectrum4 = not supported
spectrum5 = not supported spectrum6 = not supported
cap ---
spectrum1 = 136k spectrum2 = 340k
spectrum3 = 680k spectrum4 = 952k
spectrum5 = not supported spectrum6 = not supported
This table extends the adslLineConfProfileTable and contains enterprise-specific xDSL configuration information. Entries in this table apply to more than one type of DSL modems
SnmpAdminStringAn octet string containing administrative information, preferably in human-readable form.
To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 transformation format described in [RFC2279].
Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited.
The use of control codes should be avoided.
When it is necessary to represent a newline, the control code sequence CR LF should be used.
The use of leading or trailing white space should be avoided.
For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided.
For information encoded in 7-bit US-ASCII, the UTF-8 encoding is identical to the US-ASCII encoding.
UTF-8 may require multiple bytes to represent a single character / code point; thus the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the number of encoded octets, not the number of characters represented by an encoding.
Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC3416].
Note that the size of an SnmpAdminString object is measured in octets, not characters. SIZE (1..32) · OCTET STRING · hint 255t
This object is used by the line configuration table in order to identify a row of this table.
When `dynamic' profiles are implemented, the profile name is user specified. Also, the system will always provide a default profile whose name is `DEFVAL'.
When `static' profiles are implemented, there is an one-to-one relationship between each line and its profile. In which case, the profile name will need to algorithmicly represent the Line's ifIndex. Therefore, the profile's name is a decimalized string of the ifIndex that is fixed-length (i.e., 10) with leading zero(s). For example, the profile name for ifIndex which equals '15' will be '0000000015'.
