Type of cable (actual cable)

[youngqb]

Hi,

Hoping for some help.
I've had ntl cable broadband for a couple of years, no real problems so far. I'm looking to move my cable modem to a different part of the house and have a problem. When the installer originally came, it looks like he has drilled through a dwark wall under my house, came back up, put the cable end on, then went back down and sealed the hole in the wall. I could say he was being very thorough, but it's given me a problem in that I can't pull the cable back through the wall and into where I now wish it to be.

So my question is....if I remove the end off the cable (chop it off), where can I buy the fittings to re-do it? I presume maplins carries them, but I've no idea of the actual cable type, or end-fitting is called. It's a screw-in fitting to my cable modem.

Any and all help appreicated.

Thanks,

youngqb

officaly your not supposed to even touch the ntl cable, i believe they will relocate it for "fee"

unoffically yes i believe you can order the cable from maplins and the likes of and someone here will probably give you the part numbers you need...

really depends on how much the materials cost and what it would cost to have NTL relocate the connection point.

becuase if its not much more to have NTL do it then you might as well take that route becuase at least if they Screw something up its their problem.

However if you screw something up they may well wish to know what you were doing screwing about with their termination point/cabling in the first place!

there is also the factor of increasing the cable lengh may have an effect on power levels to your modem and if its marginal at the moment the difference may be enough to knock it offline or something.

may i suggest you wait for someone who knows what they are talking about to post before you continue (becuase im only repeating what ive picked up on from previous posts so it may not be 100% accurate)

as dragon says, you shouldn't really be touching the cable. i think the charge for relocating is £25 (i think there was a thread about new charges posted recently).

having said that, any decent electrical store will sell you some coax and an F type connector for a few pounds...but remember, modifying any of ntl's equipment is against the terms and conditions of service, so strictly at your own risk!

[jrhnewark]

I believe it is £25 - if nowhere locally can sell you some decent coax (you need CT100 or FT100 (or 125), not dodgy 'normal' coax), Maplin sell a wide range of everything you need online.

Anyway, it is an "f-type" fitting. Just be careful when you strip the end of the cable to re-fit a connector - make sure none of the outer braiding is touching the inner core, etc.

Once you've done it once, you can do it a thousand times.

I don't think this is a good idea as what NTL installed cable ect is their property and should you have to call them out, they would have a record of their installation and might get the sad on!!!

Doubt it. Would they also have recorded that they couldn't be bothered to cut some cable down to size so left an extra 15ft in the corner of my sitting room?!

[hairy_mick]

you need a tool that strips the cable back to the correct size also the ppc tool is used to compress the connector on to the cable if you atempt to do it your self then how are you going to check the levels do you have a te 1250 meter if not then get ntl to do it 25 quid and any problems its down to them. also if they do noise busting they can trace it back to the house then your in for it.

Can I ask why you want to move the modem, apart from it being in the way( could you not fix it to the wall.

Why not just get a cat5/long usb(not good) cable and run that into the room you want or am i missing someting!

Or you could buy a wireless router and go wireless.Or you could try homeplug and network your whole house over the mains http://www.homeplugs.co.uk/acatalog/...FTdBEgodaGgUvQ

and may I add cuz no one else has to the forum enjoy your stay

I agree with some of the above posts, £25 is not much if you think about it!

By the time you go get the cable, connectors, clips etc return home spend the time doing the work.....

Isn't it easier to call a free phone number and have them do it?

At least when the engineer goes you know your signal levels etc are all ok and you got the proper kit installed which will help reduce any poss faults in the future!

Thanks very much for the various replies.

I'm not sure if I've articulated my problem right. All I'm looking to do is take the connector off (f-type, thank you very much for letting me know what it's called), re-routing the cable then reapplying the connector. I would only do it if I thought I could do it prooperly, and without loss of signal. Your right in saying that £25 is not much, but I imagine the crimper and connector will cost less than £5 in maplins, and I think I've got a multimeter around somewhere. I'll have a look and see what I can pick up, and make a decision later, but in the mean time I'm very greatful for the speedy responses. Now that I've found you all I imagine I'll be lurking around for quite some time.

Thanks again.

why do they need crimping? Ive used threaded ones that just thread down on the cable

[youngqb]

I was assuming it was crimped down, looks like a fairly robust connection.

Might be useful if I decide to do the job myself. Any comments appreciated.

First it is against T&C's for you to mess around moving your equipment, ntl do log where the modem is in your house so they would be able to tell if you have moved it.
Second a multi meter will not do you need to measure the db's not volts etc.
Third the F is a mechanical joint not a threaded one, these are not up to the spec for what is required.

To sort your dilemma out the easiest way is run a cat5 cable from the modem where it is now to the new location, you can run up to 100 meter's and you are not breaking T&Cs, easy.

To buy your own tooling it would cost
£12 for the cable strippers
£48 for the compression tool

Good coax, joining new and old cable with 75ohm impedance connector.

Still will cause micro-reflections on the cable but so long as the connector and cable you use is good quality and 75ohm impedance shouldn't be a major issue.

Use anything that isn't 75ohm and you may see .... issues.
