Any telecoms experts in here?

We have just converted an old building on the farm into a holiday flat and are looking to add a phone line and broadband package.

This will be about 100m away from the main farm house. We did have an engineer come out to look at installing new lines but said it will take ages doing surveys and probably cost a bomb.

We have a couple of old lines in the house that have been disconnected for 7-8 years or so. I thought it might be easier to just extend one of these ourselves and get it reconnected.

Can anyone tell me what type of cable I would need to do this?

Ive ordered a roll of this but totally unsure if it will be the right stuff?

looks the right gear, remember tho anythign before your master socket belongs to BT.
I'd wire from the socket to yer other point as you would a normal internal extension.
 
Do you specifically need to have a seperate line? Just either run external cat5 from your router to the barn or setup a wifi network for them. Off the shelf range extenders could easily accommodate 100m.
 
That's the right kit for extending the line, and it's not at all difficult. But you do have the possibility of of slowing down your actual DSL if you connect it to that point. As said, get your router near the original socket, then route out the LAN either WiFi or run an external ethernet cable out to the barn.
 
It does really need it's own line yes.

Would cat5 not slow down at that range? I have a couple of 30 odd meter lengths but never thought about doing it that way.

If I did just bodge an extension with the external cable is it difficult to do?

It will slow down even with the external extension cable?

The original socket seems to be left loose on the end of the cable coming through a window at the moment. Is there nothing I can do to just unwire the socket, connect it up to some longer wire and put the socket back on the end in the barn?

Ethernet could be a possibility for the short term but we want a phone in there also soon.
 
You wouldn't necessarily slow down, but if you run 100 Metres of Cat5 you'll potentially suffer from packet loss as it's only rated up to 100 Metres, usually you'd put some sort of repeater in at 90 Metres. You should be fine with a WiFi repeater though to get the internet into the holiday flat.
If you extend from the old master socket with 2 pair cable, you should be fine running out to the holiday flat for another DSL connection, but you may slow down the actual speed the DSL syncs up at.

I think you're pushing the limits too far for an Ethernet connection. You say your out building is 100m from the house, then this is at the absolute limit for an Ethernet cable without plugging in some extra hardware to boost the signal. The volts drop is just too much for a decent connection.

The maximum length for a cable segment is 100 m per TIA/EIA 568-5-A. If longer runs are required, the use of active hardware such as a repeater or switch is necessary. The specifications for 10BASE-T networking specify a 100 metre length between active devices. This allows for 90 metres of solid-core permanent wiring, two connectors and two stranded patch cables of 5 metres, one at each end.

What does sync speed actually mean?

Thanks again

I think im going to have to give BT another call but everytime I speak to them they are useless. Do you think they could move the line for me without causing problems?

Basically it's how fast your DSL line actually connects to the internet. The further from the exchange you are, the lower the speed, so adding another 100 metres may drop it even further. However, if you use something like a WiFi extender to get internet out to the holiday home, with the modem being in the farm house, it'll most likely be a lot faster than how fast you connect to the internet anyway.

In reality you can go over 100 metres, it just depends on the situation.

It doesn't suddenly stop working when you get to 101 metres. It just needs to work at at-least 100 metres to be within spec.

If you install network cable you could run it at 100 Mbps using two of the pairs and have a voice line running over one of the spare pairs.

So it could effect download rates?

To be honest we are nearly 2 miles from the exchange anyway. Daytime in the house on AOL we get about an 8meg connection but this drops a lot during peak times. I can't imagine another 100m would effect this or am I thinking on the wrong lines?
 
Another 100 metres shouldn't make much difference if you use decent twisted pair cable (CW1308, Cat5e, Cat6, etc.).

They'll be some difference, but you should still have a perfectly acceptable connection.

Yeah I know, I was just trying to inform the OP that anything approaching or over 100m would give very poor performance. Jeez. :rolleyes:
 
Isn't it a lot less when using it for 10Gbit? Something like 50 odd metres with Cat6?
Regardless, as it's still pushing the limit for a 4 pair CAT5/6 cable run for LAN lol.

As for line speed, it will effect it, by how much however, I can't say. But you can do a test yourself I guess. I can't see it making a huge difference however. I take it you're looking at extending out a wall socket from the main BT wall socket in your house?

How do you intend on getting the cable from the main house to the out building? Overhead? Through a buried duct?
