Is there anyway to figure out what kind of cabinet I'm on?

If you're using DSLstats, the Stats page will tell you the DSLAM type. BDCM (Broadcom) means it's a Huawei cabinet. I don't recall offhand what the ECI DSLAM is, but it's different.

I believe it is IFTN, at least that's what mine says

IFTN == Infineon

Huawei band plan (updated HG612 firmware):-

Discovery Phase (Initial) Band Plan
US: (7,32) (871,1205) (1972,2782)
DS: (33,859) (1216,1961) (2793,3970)

This is from my local ECI/IFTN  Cabinet

Discovery Phase (Initial) Band Plan
US: (6,31) (882,1193) (1984,2770)
DS: (33,857) (1218,1959) (2795,4083)

I presume there's a formula to work out what these mean to the end user?

For future reference Ive added these to the DMT page VDSL2 band plans

I presume there's a formula to work out what these mean to the end user?

Yep there is.  However, there's too many variables to work out what it means for an individual line, but in an attempt to put it in a nutshell... 

IF there was no such thing as PCB and PSD Masks
AND IF the line had sufficient SNR to fully load all bins
AND IF the line wasnt interleaved and didnt have to carry error correction overheads
AND IF the line could sync at its full potential not restricted by any caps THEN:-

A user on a Huawei cab could achieve a max 70140 Up and 164880 Down
A user on an ECI cab could achieve a max 67320 Up and 170700 Down

EDIT: I guess no one is really that interested in this info, so unless there's any interest then I won't bother with checking what the HG612 might say (if it reports any different that is)/post further updates on anything I find relating to this.

I am, however i just have nothing to really add to this conversation, I donno how to check my cabinet with a HG612.

I donno how to check my cabinet with a HG612.

As mentioned above theres a couple of ways of doing this:

1) If you are using DSLstats.  From the Stats tab ->

Code: [Select]

Stats recorded 16 Jan 2015 08:49:38

DSLAM/MSAN type:        IFTN:0xb204 / v0xb204
IFTN = ECI or  BDCM = Huawei
 


2) From your line stats -> pbParams

Check the Band Plans in use against the table here

I meant if my local cab has been modified or updated with G.inp support . band plans and cab type is obvious from dslstats.

Hi Ixel,

I'll give the HG612 a try soon, most likely in the next few days, and see what it says. The ASUS is definitely syncing below the maximum downstream sync rate set on the DSLAM (49Mbps, syncing at 42125Kbps) when I don't specify a manual PMS (specifying a manual PMS for the downstream is what allows me to specify a different max/min sync rate, INP and delay), even though I have spare SNR (13dB~) and the target SNRM is unchanged (6.0dB). If SOS is actually now enabled on the downstream then I presume that's why the SNRM is higher than I'd expect and why it's not syncing much closer to the 49Mbps downstream speed banding. If I discover anything else odd in the meantime then I'll post a reply here.

If SOS is enabled then I imagine I should get an identical sync rate and similar SNRM on the HG612. If it's not then I should sync much closer to or at the 49Mbps maximum sync rate and/or have an SNRM much closer to 6dB, which would mean something funny is happening with my ASUS if so - in which case this would unfortunately dash my hopes so I hope that's not the case. I haven't been able to override the SOS or SRA configuration in the past so I can't imagine so.

Did you get round to trying out the Hg612?

Now that my programs appear to deal with & plot various G.INP enabled graphs, I'd like to see what stats you get from your connection when using a HG612.

I have updated my programs based on stats from just one user who enjoys the full 80/20 with quite significantly higher attainable rates.

A lot of data in his raw stats shows as zeros, so it might be useful to see if yours are any different due to not being able to sync at 80/20.

I have attached 2 montages to some of the G.INP related data.
 


If you sent PM including an email address, I'd happily forward my updated data harvesting & graphing programs for you to test & report back.

There is no evidence of G.INP being enabled on my long length connection yet, so I am unable to test anything at my end.

[Ixel]

I see.

Yes, I did briefly try the HG612 but no sign of G.INP. Since then the ASUS is no longer reporting it. I'm on traditional interleaving at the moment.
