Any reason you're still bothering with BT jacks when RJ45 are so much cheaper?

I've possibly got access to a reasonable number of 2nd hand (installed but never used before being removed) BT keystone jacks if you're interested. DM me if intersted.

sbiddle: Any reason you're still bothering with BT jacks when RJ45 are so much cheaper?

Just ignorance. It is standard in pabx office environments, but not homes. Also, I have no experience in data cable installation. More ignorance. More questions..



  • Is there an electrical difference between the telepermitted BT vs straight RJ45, or have all components been eliminated from the latest telepermit 2 wire sockets? or is the only difference a retro ringing capacitor?

  • Daisy chaining / star is straight forward and provided for with telecom style sockets, how is this done with RJ45?

  • Ok to use cat5 instead of Telecom type cable?

  • Ok to mix the two types of cable and BT and RJ45 sockets?

  • What tools/costs are required to do the RJ45?

  • What is Telecom contractor attitude towards home RJ45 installations?



I'm considering doing the install as a favour for an utterly non-technical friend so I'd like to avoid any situation he has to explain to Telecom.

The latest 2c jackpoints have no components on them, pretty much the same as an RJ45 jackpoint.

Well, I take them all back to a patch panel. Then, I have an area that I reserve on the patch panel which I loop so that those ports are "telephone out" that I can then just patch through to any port required.

My understanding is that cat5 cable is acceptable.

I have some rj45 and bt sockets at my place. Really should pull more cable and make them all RJ45 though.

Depends on where you get them from. I have just brought the stuff on trademe which had krone punchdown blocks on the back. There are people selling 5 cat6 keystone modular jacks for $15. Much cheaper than the BT jackpoints. Having said that, see what is involved in making the BT jacks at this link
www.telepermit.co.nz/PTC226_2006.pdf

No idea, but, I would assume they are becoming more common. Probably just not covered under wire maintance costs.

Firstly if this is a new install you should be looking at the TCF Premises wiring guidelines, www.tcf.org.nz/premwiring any new wiring jobs should wired with this in mind.

Daisy chain wiring is an absolute no no for new environments, if the rewiring is an upgrade then you should be planning to upgrade existing daisy chain wiring to a star configuration back to a central point.

Cat5e cable has been the norm for most phone cabling for a number of years now, there is no point in using cat3 phone cabling, which is quite often more expensive.

You can mix sockets fine, but if you're retrofitting a place with star wiring you would be stupid to do so since it removes a lot of flexibility if you want to use jacks for data.

To punch down a RJ45 you need the same type 110 punchdown tool as you need for BT jacks.

I don't know what the official atitude is towards RJ45 installations now, but considering that it's now accepted as standard practice to use RJ45's for new installations I don't see why they would have issues.

We (Electrical company) have been using RJ45 jacks since 2004 in all commercial and domestic jobs (Large apartment blocks included) - we simply include a RJ45 -> BT adapter for about 3 of the outlets in the residential premises, and more on request.

and it is *still* cheaper than using BT jacks. None of this daisy chain crap, and the ability to patch and change outlets as needed.

Wouldn't it be cheaper just  to cut off the BT plus and put on RJ54s rather than supply  RJ45 to BT converters??

Not when you factor in the cost of labour vs the cost of the converters. Additionally that doesn't give the client the flexibility to change devices without needing a technician.

That, and the end user might not have moved in when the job is compleated (new buildings etc). Some people might not be too pleased with you cutting off the end of their cable (for whatever reason).

Not all RJ45s will use the same punchdown as BT jacks - the grey one will not work on many jacks and you need the yellow ones.

There aren't many phones/faxes/modems that don't have RJ11 connectors on them. Swapping the actual cable on the device can be just as easy!

If it's a new building it will be structured cabling with RJ45s. The customer has know idea whats at the end of the fone cord  so replacing  BTs or RJ11s with RJ45s  won't worry them the slightest.. The labor cost of doing large runs of line cards in small.. We do it to  about 90 of our installs .  All our fones come with RJ11s on them and you don't plug those onto structured cable jacks..
