BT to Launch 55/10 Product?

Tacitus · Dec 16, 2015, 18:49:09

Over on TB it's being reported that BT/OR are to offer a 55/10 product from next month. I wonder if iDNet have any plans to revise their offerings to incorporate this?

My max attainable rate DS hovers around the 53/57 mark depending on which router I have running - I'm around 0.4 mile from the (Huawei) Cabinet. FWIW I generally get a higher rate from a Broadcom based router than one with a Lantiq chip.

Given the right download allowances and provided this product is priced appropriately, for a lot of people it would make more sense to go for that than pay for the full 76Meg which they cannot possibly get.

You should use the Broadcom based routers otherwise G.inp wont work if you use a Lantiq chipset on Huawei cabs, that's probably why you have a better connection. ECI cabs have not been enabled for G.inp, or vectoring (if that happens) and there is some doubt if they ever will as ECI cabs cannot dont do G.inp on the upstream,s o BTOR had to change the way G.inp worked and re-roll it out to Huawei cabs. Loads on Kitz and Thinkbroadband about all this. Basically ECI cabs were cheap and the bean counters it seems did not check their compatibility. ECI Cabs also they all have had to have heating pads put in them, as they let in tow much damp air due to the large vents on the front which then caused corrosion internally

Interesting post Garry. I've used a Draytek (Lantiq) and although according to the stats G.INP was enabled, I can't be sure it was actually doing anything. All I could see was that the max attainable was generally that bit slower than the Broadcom based kit. Stability wise there was nothing between the two, both were pretty solid.

I see Draytek have updated the firmware a couple of times since then so it might be worth updating and trying again. Mind you given my current router seems pretty happy, I'm inclined to leave well alone. Now I'm on Fibre the days of trying to squeeze the last bit of speed out of a rubbish line seem long gone. Hopefully that's not an invitation for it all to go belly up.....

Round here most cabinets seem to be Huawei as they do near my sister. In fact take up in my sister's area must be good since in some places they are installing new cabinets alongside the existing Huawei 288s.

Certainly the Vigor 130 supports G.INP on the later firmwares. I'm on an ECI cab so there's no advantage to me to date and I think unlikely to be the case. I'm a fair way from the the cabinet so a 40/10 product is ideal for me although on a good day the max attainable rate does rise to 52-53 down. The reason for the 55/10 I guess is for the BT UHD TV streams .

Regarding Draytek stats either via the menu or telnet, the max attainable rates differ for me each time I input 'vdsl status' Regarding G.INP if ReTxEnable = 1 G.INP is enabled.

G.inp was enabled in some Lantiq chipsets on some routers/modems. ECI cabs still have nothing sadly.The BT ECI modem can do downstream G.inp as can the cab supposedly. Huawei have had G.inp for almost a year (G.inp Mk1 was up and downstream but that caused havoc for people using ECI modems with sync speed drops and large latency increases on Huawei cabs) Mk2 G.inp was then rolled out with downstream only enabled and occasionally its been reported on upstream, but this is all on Huawei cabs a SP08 firmware was rolled out to HG612 modems as well. BTOR seem to have created a two tier cab system caused by penny pinching, ECI cabs were cheaper in the middle phase of the roll out.

Since the product is supplied by Openreach, presumably it will be available to ISPs via BT Wholesale. It will be interesting to see how many offer products based on it. TBH 40/10 is OK for me, but I could be persuaded to go for 55/10 if the price was right. I've noticed how my usage has gone up in leaps and bounds since moving to Fibre at the start of the year.

The only defence I can give BT for the ECI cabinet debacle, is I don't think G.INP had been 'invented' at the time the cabinets were installed. I wonder if they'll be replaced when the service contract/warranty runs out around 2017

G.inp (PHYr) has been part of the many Broadcom chipsets since 2007, Steve.

Well that's potentially that theory out of the window but did BT specify G.INP compatibility when they put the tender out I wonder.

I cant see BTOR replacing ECI cabinets mine was put in in 2013, there were hundreds of thousands installed at that time, I cant see them being replaced, i'm betting BTOR is hoping G.fast will cover this glitch up.

G.998.4 - The ITU standard name for the technology which was standardised & approved in 2010 So I think it was, whether the change in how the DLM works caused the issue when BT were found to be infringing two ASSIA patents with its NGA DLM system who knows.
