This parameter provisions the VDSL physical entity at start-up by defining whether and how the line will be channelized, i.e. which channel type(s) are supported. If the line is to be channelized, the value will be other than noChannel(1). This configuration can be activated only during start-up. Afterwards, the value of vdslLineType coincides with the value of vdslLineConfLineType. Depending on this vlaue, the corresponding entries in the ifTable for the interleaved and the fast channels are enabled or disabled according to the value of their ifOperStatus. Defined values are: noChannel(1) fastOnly(2) interleavedOnly(3) fastOrInterleaved(4) fastAndInterleaved(5) Note that 'slow' and 'interleaved' refer to the same channel.
