GraemeReddish Posted March 17, 2016 Share Posted March 17, 2016 Hi, I have a job to install a galaxy G2 using a digicom, the customer has BT infinity fibre (FTTC) does a standard DSL filter work with the broad band or does it have to be specific to the fibre service? Thanks, Graeme Quote Link to comment Share on other sites More sharing options...
Simlec Posted March 17, 2016 Share Posted March 17, 2016 The customer should have a filtered master face plate, so your connection to the voice part will not require any filters nor do the telephones. Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted March 17, 2016 Share Posted March 17, 2016 As above. With vDSL it's filtered at the master socket. Quote Link to comment Share on other sites More sharing options...
GraemeReddish Posted March 17, 2016 Author Share Posted March 17, 2016 Great stuff it's only just getting up and running around these parts so not had an install on one yet, thanks for the prompt replies Quote Link to comment Share on other sites More sharing options...

datadiffusion Posted March 17, 2016 Share Posted March 17, 2016 (edited) I've seen BT do all sorts, isn't engineer installation over now as they've proven 'acceptable' performance on self install plug in filters? When we got upgraded here at the new house, we had to wait for the guy to do the gubbins outdoors at the cabinet, but no appointment in the house. We were send a HH5 with plug in filters... Of course I've fitted a mk 3 faceplate, but if I hadn't we would have had infinity on a 1980s linebox and plug ins... suspect they just wing it now, hoping that only 1 in 4 will have to call in an engineer to the house itself...

GraemeReddish Posted March 18, 2016 Author Share Posted March 18, 2016 Sounds about right, for the £10 they are selling for on eBay I'll buy one and keep it on the van incase Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted March 18, 2016 Share Posted March 18, 2016 We were send a HH5 with plug in filters... Maybe an admin **** up? HH5 can do ADSL and VDSL automatically You maybe right, I suppose for most people they will see an improved in speed without coming to site. I can't say I have seen Infinity without a MK3 etc round here. Quote Link to comment Share on other sites More sharing options...
Adi Posted March 18, 2016 Share Posted March 18, 2016 I'll check what mine is. Quote I really can't be ar**** with it anymore. Link to comment Share on other sites More sharing options...
GraemeReddish Posted March 19, 2016 Author Share Posted March 19, 2016 Had a chat with the customer earlier and they are using a plug in filter supplied with the HH5, as mentioned before I will install a mk3 faceplate as there only a couple of quid more than the Z-blocker that I normally use.

datadiffusion Posted March 19, 2016 Share Posted March 19, 2016 (edited) Yes, a faceplate change is a million times better for you and the customer, EXCEPT when they have the hub or similar upstairs on an extension.... Although if they have 6 core running up there already I've never, ever had an issue with making the green pair, for example, DSL only from the unfiltered block on the plate. I then change the affected socket for a double euro with one BT on the blue/orange pair and one RJ11 for the modem only on the green etc... To be honest not had to do it for ages though with WW and 3G type comms. Maybe an admin **** up? HH5 can do ADSL and VDSL automatically You maybe right, I suppose for most people they will see an improved in speed without coming to site. I can't say I have seen Infinity without a MK3 etc round here. Yes, I think it's intentional. As you say most will just see an increase and be happy, even if it could be even better, they'll never know. In dire cases they'll phone BT but if it saves 3 out of 4 home visits they're laughing. Here we go, it's official, Infinity self install, even mentions 'if you DO already have a 'double socket', 'otherwise use plug in filters...' http://bt.custhelp.com/app/answers/detail/a_id/47225/~/help-with-setting-up-bt-infinity-yourself Edited March 19, 2016 by datadiffusion Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted March 19, 2016 Share Posted March 19, 2016 The reasoning behind the Mk3 is to remove the interference from the ringer circuit that happens after the master socket. May find that other FTTC providers have been switching over without getting Openreach in, so BT are doing the same. I don't see why they don't supply you with a plug in master socket adapter plate filter as standard instead of the microfilters. Come to think about it they make money selling them at the BT shop.

Eh? I thought it was to improve noise on the broadband what's it gotnto do with ringer circuit? I may have read you wrong Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted March 20, 2016 Share Posted March 20, 2016 If the DSL is not filtered at the master socket it will be running around your house and picking up interference. Some of this comes from the ringer circuit. Also you want to filter the DSL as close to the exchange as possible to get the fastest speed. Another point to note is if you do use microfilters you may want to swap them out, the components in cheap ASDL filters may not be rated for the higher frequency of VDSL.

al-yeti Posted March 20, 2016 Share Posted March 20, 2016 Ok I understand that , but I didn't think the mk3 was introduced for this reason, more for interferencebon broadband and as you said increase speed Quote Link to comment Share on other sites More sharing options...
datadiffusion Posted March 20, 2016 Share Posted March 20, 2016 (edited) The thing is the plug-in ones BT supply with the HH5 kits are the cheapest and nastiest I've ever seen! A few years ago I was given a sample of a very nicely produced Fujitsu UK-made plug in filter, they must have been trying to impress BT for a bulk order, as I never saw them ever again or for sale etc... although if you google 'Fujitsu Microfilter' on ebay used ones can be found.

GraemeReddish Posted March 26, 2016 Author Share Posted March 26, 2016 Installed the MK3 and all working well, the HH5 was on the master but the MK3 does have an un-filtered output if its on an extension, these should be standard issue by BT, and yes the standard filters are nasty.

datadiffusion Posted March 26, 2016 Share Posted March 26, 2016 (edited) Yup the tiny 'hidden' unfiltred o/p is handy, amazingly some BT contractors don't even seem to know what it's for Interestingly the 'Fujitsu' dongle (if it ever really was made by them) lives on here... http://www.pressac.com/_literature_3542/DS034_ADSL_Microfilter Edited March 26, 2016 by datadiffusion Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...
