Strong noise for three seconds after beginning of conversation - VoIP General, VoIP News, VoIP Providers, VoIP hardware, VoIP software, VoIP Technology

Hello,

on the analog line attached my DECT telephone hangs my 7050 with current firmware, at FON1. Whom I am called now over fixed net, a very strong noise is to be heard for the first three seconds of the discussion (and only so long, thus not the well-known noise). One does not understand its opposite no more. Afterwards everything in order.
If DSL cable is separate from the fragment, at all no problem.

What can lie?

Ciao

Sorry only a few counter questions

You have the noise only (and always), if you are called from the fixed net?
Are DECT Basisstation, and/or. Mobile part far enough of the 7050 removes?
Did you switch already times the WLAN off?
You do not have the noise, if the DECT Basisstaion is attached at the TAE box directly?
Do basis station and FB hang on the same plug socket?
Did you put already times the plug power supply unit in of the FB differently?
Which language coding do you use?

kind regards
Dieter

Examine times your telephone house wiring whether there an electronic change over switch (AWADO/AMS) or a parallel telephone before the fragment is present. An indication for a AWADO/AMS is, if it in the house several telephone doses have, but only one telephone number…

* You have the noise only (and always), if you are called from the fixed net?
I do not have VOIP numbers in enterprise; Rush tut's however with outgoing like arriving (fixed net) calls.

* Are DECT Basisstation, and/or. Mobile part far enough of the 7050 removes?
Meanwhile…

* Did you switch already times the WLAN off?
Is always deactivated.

* You do not have the noise, if the DECT Basisstaion is attached at the TAE box directly?
No.

* Do basis station and FB hang on the same plug socket?
Yes.

* Did you put already times the plug power supply unit in of the FB differently?
Is that a joke?

* Which language coding do you use?
Only fixed net, s.o.

Thanks for your assistance!

Hello!
That is to cause actually occasionally miracles and is not not so wrong, as it lets assume at first sight. Even if in both electric rectifiers filter capacitors sit, nevertheless a certain “remaining ripple” remains on DC voltage. If one turns the power supply plug, in each case the other end of the electric rectifier receives the phase and opposite zero voltage, whereby a small temporal shift results. And if the two different devices are then connected and to certain times not the same potential on the feeder line, which can be expected, to have, do not come it to humming, which possibly. one strengthens. Should not happen actually, already not at all with circuit-moderately well designten devices - can however quite…
On the other hand I cannot imagine that in your case is applicable, since only the first few seconds of the discussion are concerned.

Did you already examine whether there is an electronic change over switch before the fragment?
If not, times examine the fragment (with neighbours exchange for a test).
The same problem exists with detailed calls, if your telephone is instead of the Fritz box telephone cable directly in the fragment (DSL naturally further attached!) ??

@friburg
Mean reference to the language coding can you forget, since you have the effect over fixed net.

Did you attach the DECT telephone already times to Fon2 or Fon3?

There is always exactly 3 seconds, and/or. if it is always accurate the same time, then possibly a software component moves into the suspicion. With different times electrical influences can be the cause.

You come testweise times at trying out Fritz! Box ran?

kind regards
Dieter

thus, the following:

the noise gives it also, if I put the telephone directly into the fragment,
and there is also a change over switch before the TAE. Thus probably is the Fritz box from the cutter.

Interestingly enough there was another noise, than I had put the telephone in at another convenience outlet.

And: As I recently the order of the plugs within the connector strip (telephone, Fritz,…) exchanged, was peace. However 10 minutes later ging's again loosely.

On what interprets now? Fragment broken? Change over switch 'raus?

Change over switch raus!
Before the fragment has to search nix.

dh. Copper cable if necessary. twist, where the switch was, simply? Lustre terminal?

Is it difficult, the two (?) To switch Drhtchen to the TAE correctly?

The change over switch contains electronic construction units, which make the DSL transmission signal of your box “audible”.

These change over switches originate from a time, when it still no DSL gave…

If you it further to use want/must (e.g. 2. Telephone in the house and/or emergency operation with power failure) you must him behind the fragment put.

Eliminate otherwise best completely.

[Edit] lustre terminal/to twist goes.
Polarity of the 2 wires is no matter in principle, but it cannot harm, on the vein Ringel to respected (no black Ringel/1 Ringel… etc.)
But caution, there are 60 V on the line. Usually not dangerously (if one of the heart stop because of “frightening” foresees), but it zwiebelt nevertheless already violently…

Is not heavy actually…. if one a lamp by lustre terminal to attach can. .sollte one also wars

If the change over switch beside the fragment lies, simply the post office wires directly into the fragment put (terminal block behind Klppchen down, marking a/b).

1. 60V are dangerous and may not not be touched!
2. Polarity of the veins is not generally all the same. It is no matter to modern TK-plants at your branches, so that also beginners your telephones run to gotten. Whether the Firtz! Box office-laterally cannot, white I. With many telephones it is anyhow important not to exchange the veins.

I do not know a similar telephone, with which the polarity of a/b plays a role. It is also all the same to the Fritz box and Konsorten with absolute security (has an electric rectifier in the entrance)
All modern POTS of devices (since liberalisation of the telecommunications market) has an electric rectifier in the entrance, which turns the polarity suitably.

Only with the 1.TAE box the polarity plays a role because of the passive test conclusion….and with ISDN it is naturally important…

To know well.

Hello is again here and has a question to the community, where I can write a new contribution?

By looking for first times dne forum range, where the topic could fit.
Then you find a button “new topic” there above direct left over the topic list.

Before you should read at least the headings of the first side of the Themenberichs and endeavor the search. Many questions clarify themselves already thereby or you find already a topic, where the problem is treated.

Hello new customer 1601, welcomely in the forum!

Click in the highest blue border on IP-Phone-forum.
Then on the suitable forum part (e.g. AVM or 1&1…)
Then on the suitable column (e.g. with AVM on “Telefonie” etc.)
Then the list srollen downward. Under the list a button is “new topic”

Whereupon press (and a meaningful heading for the topic invent!!!).

[Edit: Mega was faster. But is correct! Before with the search function it looks whether your question was not already once asked]
