Why?

IF as I and most of the others are now suspecting, your BELL CIRCUIT is using MAINS VOLTAGE directly on the Bell Push (the Bell Switch/Push by the door) , there is the distinct possibility of getting a MAINS VOLTAGE SHOCK in whatever Weather Conditions exist at the instant.

In reply to a post by konrado5:

EDIT: Phone cable is probably come in and come out from the round box. It is probably the same cable.

Don't believe that!

That pix shows only 1 circuit: Feed cable, prob mains, from L -> round box transformer -> connector block, where a loop on +ve pole, out-of-sight goes to bell-push thus

Bell push

----------------------------------------------------------------O--Block--------O To Bell Chimes
while the -ve pole in connector block O-------O goes straight through
-> Bell Chimes in rectangular box.

EDIT: Note in my diagram above I have 6 O terminals and 3 O----O connections which corresponds exactly with your connector block which consists of 3 x conductor strips joining 2 terminals each.

I agree that it looks very/most likely that it is all one circuit, possibly at Mains Voltage, I do question whether the circular box is "deep" enough to accommodate the typical Bell Transformer of the period, with 240 Volts in and generally <12 Volts out, usually with screw terminal arrangements and mounting screw holes.

Also the shorter "horizontal" wire from the Terminal Block to the Circular Box, appears to go "underneath" that Box, possibly entering it by the central (fifth) conduit hole in the base of that Box. There is no obvious shadow or such-like on the left-hand hole, unlike the longer horizontal wire.

The Circular Box appears typical of early plastic circular conduit boxes, with four holes around the periphery, and one "reinforced" one in the base - which would probably need a shallow hole in the wall (plaster).

That I recollect, the OP has not shown/described two aspects-

a) Does the longer horizontal wire in gcr7 run down behind the pipe at the left, to re-appear in xvqr as the pink-painted wire, rising up to that box?

b) The unpainted wire emerging from the top of that xvqr box and dropping vertically downwards - Where does that wire go to, termination etc.

If we are generally correct about the circuitry etc, the OP does not appear to have the knowledge to assess the probable hazards, hence my thinking that for the safety of all, the circuit requires on-the-spot examination by a competent electrician.

The bell push will not be mains operated, If a bell is mains powered there will be a step down transformer. Typically they work on something like 9V dc

In short as others have suggested, you are clutching at straws and without dismantling which needs to be carried out by a person suitable qualified it will not be clear as to what the situation is.

The concern over the bell ring button having mains to it is real, and since no-one can be sure advise to get that checked out is valid and the best practice for an online forum.

If done properly yes that should be the case, but I think like most of us we have seen some horrible lashups over the years.

If that is an old fashioned door bell that rings a bell or buzzer, there's a coil inside that type of device which can produce rf interference (it sparks)

What is frequency? I've never seen error on upstream when doorbell rings, by contrast I always see error on download.

I've talked about this doorbell with my father. He said that there aren't any transformer, transformers were used on old door bells only. The doorbell is connected directly to 230V mains. The round box is only phone box. Moreover, the doorbell push is covered (rain doesn't matter).

Although nominally the mains voltage should be about 230 Volts, in practice in the UK for historic reasons - and looking at my Mains Monitor right now, it is about 248 Volts AC RMS.

The pain voltage induced in an electric shock would be about 1.414 times the RMS value, so about 350 Volts Peak.

This in itself could render someone unconscious - and could "kill" a Heart Defribillator.

Additionally, if you are hoping to get your Broadband Download problems cured, that Bell Circuit needs to be totally replaced.

Your father's statement that the Bell Circuit operates at Mains Voltage, confirms that it is DANGEROUS!

I have never seen a Circular/Round Phone Termination Box in Domestic Premises in my 60 years experience. (Has anyone else?)

HAVE YOU EVER HAD AN UNEXPECTED ELECTRIC SHOCK?

And YOU would be LEGALLY LIABLE for any INJURIES caused to a Visitor, Caller, Deliveryman, Postman etc!

==========================

Why does it affect the Download more than the Upload?

Typically on ADSL2, the Download is running at 10 Mbps.

The Upload at 1 Mbps.


So if the Interference lasts for 1/10 th of a second, you will lose 100 Kbits of Download information; and as the Download circuit is "being pushed to its limits", it is very difficult and "time-consuming" for a Recovery to be achieved.

If it were the Upload side, it would be about 10 Kbits; and as there is less traffic on the Upload side, it is easier fo Recover and Reset.

---------------------------

Think of a typical Motorway, there is the potential for the same amount of traffic on each of the two carriageways.

Think of the M4 Motorway going in to London at Rush Hour in the morning.

If there is a crash or obstruction on the Inward East Carriageway, queues build up; and it takes a long time to clear them. The after-effects can be observed for a long time, say 5 hours.

A similar crash or obstruction on the Outward West Carriageway would have much less effect, due to the lower traffic levels.

================================

From all the evidence YOU HAVE SUPPLIED, you will NOT MAKE ANY PROGRESS in sorting out your Broadband until you do so.


AND the effects will be WORSE if you get Higher Speed, FTTC/VDSL Broadband, as in the 1/10 th second Interference period, you will lose a lot more data.
