Plusnet Hub One and G.INP as required by SIN 498

Oldjim — Fri, 12 Feb 2016 17:34:19 GMT

This question has come up several times but I have never seen an authoritative answer from Plusnet
Does this modem/router support G.INP on downstream or not and, if not, how did it get approval

Is it actually approved? I don't think I've seen an authoritative document from Openreach or BTW listing approved devices, only lists from ISPs which might well be limited to models that they sell.

The point is that

Is it mandatory to use SIN 498 compliant products?
Yes; BT Openreach provide almost all VDSL lines in the UK (for all ISPs) and they do require the use of SIN498 approved devices. You are expected to have an approved device on the line in order that they can monitor performance/stability and in the event of any reported fault/problem so that they can eliminate any unknown hardware as being the cause. SIN 498 testing ensures that devices provide adequate performance a large variety of line types and varying line quality and comply with all requirements and features within the specification.

and SIN498 states

Quote
A.4.2.2.8 Support of Downstream Retransmission (R.VDSL2.10)
Description – The modem shall support downstream PHY layer retransmission as defined in G.998.4 [6] .

So according to that it must comply

"Must" as in "Should", but is there actually any document stating that it's approved?

The ISP branded devices have never appeared in any lists of approved models, but it's been assumed that something supplied by a large ISP would have been tested and passed.

It is easy enough for (honest) ISPs to make simple statements of compliance to remove the need to rely on risky assumptions.
Arguably, if they are not compliant, given the requirement from BT that they should be compliant, then they are not fit for their intended purpose.

Strange that nobody can reply to this question, It has been asked several times with no response!

I believe that it is Openreach approved. Whether or not it's compatible isn't something I'm sure of, however the profile amendments BT made shortly after the G.INP rollout should mean there is little detriment now. It may be able to be made compatible with future firmware but again, that's not something I'm 100% on.

Chris
That isn't correct
The changes made were in relation to G,INP on upstream not downstream
Can I ask that you check with your experts whether it supports G,INP on downstream or not
Alternatively run a GEA test on several of your customers with that router and it should show whether it supports G.INP downstream or not http://www.kitz.co.uk/adsl/retransmission.htm

It does.

that doesn't mean anything to me
To add - I think it does but the awkward person I was arguing with couldn't be persuaded

Unfortunately references to version numbers of Lantiq software and firmware don't really prove anything - the TP-Link TD-W9980 had newer versions than that, but ReTx wasn't actually enabled, then TP-Link released newer firmware, containing Lantiq components with the same version numbers as before, but with ReTx switched on.
