Re: Review comment of NG-ADSL-MIB

Hello Chen Jian,

If Moti and I understood you correctly, then your suggestion was already
considered previously, but rejected. We understood that you propose to
place the channel level table under the line level table. Is this correct?


The following example, explains why placing the channel level table under
the line level table is not an optimal solution, from the memory
consumption point-of-view:

Let's assume you have a "Bronze" service-package with one channel. In the
approach you suggest the operator creates a line configuration profile for
the "Bronze" package and a single channel configuration profile under it.
The channel level table uses the line level table index and an additional
index, as you propose.

Now, let's assume there is a need to support another package, a "Silver"
service-package, with 2 channels: the same channel as in the "Bronze"
package and an additional channel.  In this case the operator has to create
for the "Silver" package a new line configuration profile (dozens of
objects that contain exactly the same values as in the "Bronze" package and
all the mode specific extensions) and create two channel profiles, from
which one is the same as in the "Bronze" package.

So, the operator has 2 line profiles, 2 sets of mode specific extensions
and both sets have the same values. The operator also has 3 channel
profiles ("Service1 under Bronze", "Service1 under Silver" and "Service2
under Silver"). The result is that, relative to the memory required for the
"Bronze" setup alone, adding the "Silver" package almost duplicates the
memory consumption in the EMS and in the embedded system.

What happens in our approach?
The operator creates a line configuration profile for the "Bronze" package
and  then the "Bronze" template "points" to it and to an "independent"
Service1 channel profile.

When the operator configures the "Silver" package he uses exactly the same
line configuration profile and exactly the same Service1 channel profile he
used for the "Bronze" package. The "delta" is: a second channel profile
(let's call it Service2 ) and a specific template (which is basically up to
5 pointers).

This is a much more optimal solution from memory consumption point-of-view.

Best Regards,

Menachem.

Hello Menachem Dodge,

    It is my pleasure to do that.

    I have some advice about the structure of the profiles.

   I suggest the channel configration may be like the
  adsl2LineConfProfSpectrumTable, embedded in adsl2LineConfProfTable. The
  index of the table is adsl2LConfProfProfileName and
  adsl2ChConfProfChannelIndex. It is may not be managed as an independent
  profile.
  There are 3 profiles, LineConfigTemplate, LineServiceProfile,
  LineSpectrumProfile , follow the TR090's suggestion. We merge the
  LineServiceProfile
and the LineSpectrumProfile to one. So, it may be 2 profile left.
      It is 4 channels in the ADSL2/2+ line now. The expansibility of the
      MIB structure is limited if there are more channels in the furture's
      technology.

      The alarm configration profile is the same.

Attach the modified MIB:
