What wiring is required to install IP Office

[carpediemnick]

Greetings,

I am looking to purchase a new phone system. I am interested in the Avaya IP office. The question I have is: Do digital ports require CAT5 cable? Is this mandatory? We have purchased a large facility; approx. 250 extensions; we were going to use the exisiting Definity system but Avaya required us to re-purchase the license. All jacks are wired with either the old "JK" wire and cat3.

Thanks!

Digital Phone only require one pair to work, on a CAT5 cable it only uses the middle pair.

if you are planning to rewire then use cat5e for everything
put it on patch panels and you are very flexible
you can put anything anywhere

If I intend to go fully IP (with all the "bells and whistles") will the digital phones still only require to work on one pair or require more pairs?

 

[tlpeter]

digital phones need only one pair so they still work when using ip phones

IP phones work on your LAN, or data network, so they require network cabling.

IPO digital/non IP phones require one pair minimum category 3, not sure what JK wiring means.

 

[carpediemnick]

JK" what i meant is the old 2-pair(red,green,black, yellow)

That usually works, but no guarantee.

Single location? Why go all IP? PLease explain the rationale, I'm curious.

there is no need to use cat 5 for keyphones they will work very happaly on standerd telephony cable most of our large installs are this way

 

[tlpeter]

but why put in two different types of cabling ?
if you put in new cabling then do it all on cat 5

one of our customers put in CAT3 for voice and CAT5e for data, while it's a very neat and clean job, I see the CAT3 as a waste of money now. Since they only ran one of each, their own people have been trying the CAT3 for additional network drops and then complained about speed and drops. I suggest running all CAT5 even if it's a few dollars a drop more. Save the next tech who comes onsite some grief and make it easy for the customers.

I think he is saying he wants to use the existing wire and not rewire everything that is why he wants to stay with IP Office.

Yes you can use the existing CAT3 for digital phones. The only difference between is the IP Office uses RJ45 connections instead of a 110 or 66 block. So you may want to setup a new patch panel to connect to your existing wiring.

The biggest reason to go with spearate cables for wiring and digital is that when the net goes down the phones still work.

The IP phones reside on the network, so they will use the network cabling like any other network device. The digital phones which are not IP can use cat3,5,or 6 , but they will only use one pair of that cable anyway, as they are traditional phones like any non-IP phone system extention.

The IP Office can deploy all IP(hardware or software based phones), all digital, all analog, or a combination of all four types, whatever you need. Don't forget wireless phones as an option as well. I even have a customer who has an IP -phone working over wireless network no problem.
