| Description | This attribute specifies the status of this entry as to
whether this entry (row) contains usable Tone Plan
configuration information (object is set to 'configured'),
or if it is empty (object is set to 'unused'), or if is
temporarily (object is set to 'reloading') or
permanently (object is set to 'lostFile') unusable.
This tone plan information for this row can be used
by a DS-1 line only if this object has a value of
'configured (2)'.
To add a configured entry in the vismTonePlanTable
table, there must be an existing empty row with its
entry status set to 'unused(1)'.
Then before this empty row in the vismTonePlanTable
table can be changed to 'configured', it must, in
one single operation, be given all the usable
values necessary to be stored in the
tonePlanRegionName, tonePlanVersionNumber and
tonePlanFileName MIB objects for this row. In addition,
those values for the tonePlanRegionName and
tonePlanVersionNumber MIB objects pair must be
unique with respect to every other row of the
vismTonePlanTable. Then, as this existing empty row
is set with all three valid entries for the
tonePlanRegionName, tonePlanVersionNumber,
and tonePlanFileName MIB objects, the Entry Status
MIB object for this row will be finally, internally,
set to 'configured(2)'. This final 'configured' status
is the direct result of correctly setting these three
MIB objects with valid data.
In no case will an external manager be able to directly
set this MIB object to 'configured(2)' by a SNMP set
command, for such a single stand alone command will
be rejected.
Once a table entry is set to 'configured(2)' with
valid tonePlanRegionName, tonePlanVersionNumber, and
tonePlanFileName MIB objects for this row, then these
MIB objects may not be modified by any subsequent
SNMP set command. In the case where a row needs to
have these objects changed, this entry must be cleared
from the table (paragraph below) and a new entry added
by the add process above.
Once an entry exists in the vismTonePlanTable table it
may be cleared and set to unused by setting this MIB
object to 'unused(1)'. But before the entry status of
any entry in this table can be set to 'unused(1)',
there is a check to make sure there is no
vismDsx1TonePlanRegion MIB object and
vismDsx1TonePlanVersion MIB object pair in the
dsx1VismCnfGrpTable MIB table that may point to or
refer to this table entry (row) with its unique
tonePlanRegionName and tonePlanVersionNumber.
Once the entry status of an entry in this table is set
to 'unused(1)', all the other MIB objects for this
table row are set to defaults or to NULL.
Once an entry is 'configured', if a subsequent card
reset occurs the VISM card will attempt to restore
all of the configuration information by doing the
normal download of the latest MIB database, set all
'configured (2)' MIB objects to 'reloading (3)', and
then do an automatic background process to retrieve
all of the tone plan files from the server since they
were not downloaded by the PXM. If this retrieval of
the tone plan files succeeds then this MIB object
will be set back to 'configured (2)'. If this file
retrieval does not succeed, then this MIB object will
be set to 'lostFile (4)'. In no way will an external
manager be able to directly set this MIB object
to 'reloading (3)' or 'lostFile (4)' by a SNMP set
command. |
