Phone line extension help

[rizred]

Hiya,

I have just helped a freind out with putting in a phone extension socket into a shed/ office conversion.

He put a 4 core cable from his main telephone (BT) socket to the new office location. We connected the cable ontop of the existing cable in the bt socket and put a new pace plate on the office end.

This gives him the ability to have a phone in the house and in the new office.

However with a phone plugged into the new socket, his broadband which is still connected to the origional BT socket does not work?! If the phone is taken out of the new socket the broadband works again!?

Any ideas?

Hopefully i've explained this well enough!

Plug a broadband microfilter into the extension and plug the phone into that.

Might be better to put a single filter at the BT master socket for all the phones.

NTE5 compatible ADSL filtered faceplate with connections for filtered and unfiltered extensions. The Austin Taylor Faceplate Splitter is considered by some installers to give superior performance on installations which are a long way from the exchange or for some other reason have a marginal broadband signal.

There are other suppliers of similar equipment

can you hard wire into the back of that?

There are two sets of terminals on the back of the removalable front plate

One set of terminals for the telephone wiring and a separate set of terminals for the wiring for the ADSL circuits

I dare to think an "office/shed" conversion is going to need both?

The NTE 5 appears to be in the house where the OP requires both phone and broadband. There for phone and broadband for the house are connected to the NTE. Only phone wiring needs to be taken to the shed / office.

you have no idea what the O/P wants - stop confusing the issue.





Micro filter required - that simple.

 

[Steve]

Why are they called micro filters? Are there large filters available?

 

[bernardgreen]

Micro ? possibly because the sound of the word has marketing value in the world of micro electronics. And maybe because some of them have a micro specification.

Some "Micro" filters tend to be suitable for only a single telephone due to them having a maximum DC current capability.

Face plate filters ( but not all of them ) have a higher maximum DC current so they will operate if two or more phones are off hook on the circuit the filter is fitted to.

Actually you may be wrong. The phone in the shed plugged into the new long extension cable to the shed may be reflecting the ADSL signal such that at the ADSL modem ( router ) there is sufficent amplitude and phase shift of reflected signal to cancel out or seriously distorted the ADSL signals rendering broadband non functional.

A micro filter in the shed may solve the problem by reducing the reflection but the long cable to the shed is still a stub on the ADSL route and will therefor contribute out of phase reflections of the incoming signal to the ADSL modem unless properly terminated.

If the shed end of the line to the shed is properly terminated for ADSL to prevent reflections then the termination will have to absorb rather that reflect the signal. That means a reduction of ADSL signal at the modem.

rubbish - just admit your mistake and "move on"

I'd say it's more than reasonable to make the assumption that the friend of the OP only wants a phone in the shed.

Since you can't fit 2 modems to the line you would have to MOVE the modem out of the house and into the shed. How likely is this? Further to this, if it had been the intention to move the modem to the shed they would have already fitted a filter of some type, in order to get the correct connections for both phone and modem. So if your argument about what the OP might require holds true then your solution would already be in play.

So, the person suggesting fitting the faceplate has got it spot on. It's not the only solution but it is the best one. For a number of reasons, some of which have been touched on already.

Even if a network connection is wanted in the shed, you can't hook up two ADSL modems to the line, so if you still wanted access in the house as well you'd have to run an Ethernet connection from house to shed.

I've used the XTE2005 filters from ADSL Nation quite extensively on long ADSL lines (almost 5 miles in the area in which I live), and have found no problems with them. They provide both filtered and unfiltered terminals:
