questionsshould i run 2x lan lines and 1x phone line to…


Any reason you can't just install wireless internet and VOIP?

Not sure if your project is limited to cubes or if it includes any conference rooms, but using LAN lines puts a hard limit on the number of connected employees sitting at the same desk/conference table/etc. without using an unsightly router or splitter.


Is Cat6 really necessary? It might be cheaper to just go with Cat5e. It still supports up to gigabit speed. While it isn't as new, it might be a little cheaper per cube.

How large of an office are we talking about? 50 people? 100? 200? 1000?


@smallbigtall: VoIP is planned for the future -- probably in the next few years. The area of renovation does include 3 conference rooms, a couple of printer-type areas and 45 cubicles (spread over two wings of the building) and 3 manager's offices.

"Just wireless" will not cut it. There is wireless that is available in the conference rooms and there's pretty good coverage throughout, but most of the people will have desktops in their cubicles.

If this were a smaller office, wireless might work, but we're talking an area that's supporting 100-125 people (one section of the wing won't be replaced this year). It's an IT area as well, so there's TONS of data being processed and moved around -- wireless wouldn't be able to keep up with that amount of traffic.


"The incremental cost of doing it now is XXX, the cost of realizing we need it down the road and doing it then is 400% of XXX" or something.


If you're seriously planning to go VOIP, maybe consider that in your network planning. My desk has 2 network drops, one is for the VOIP phone and one for my desktop. If I need to plug in another (like my personal laptop or if someone is working with me at my desk) then it can go into the back of the VOIP phone as a pass-through.

Is 3 better than 2? Yes... Are the new drops going to be for power users or customer service agents? That might be a factor too.

What about using 2 plus WIFI instead of 3?


The last time I planned out an office area, supporting approximately 80 or more people (I don't remember; machines were more important to me than people), each office had two connections for network, and one connection for phone, per person. Phones were digital phones (not analog), and wired to a Nortel switch in another building, so that was an indirect cost already taken care of in the building overhead. Sorry I can't share the Visio or other diagrams with you; they were very informative.

Two connections per person still did not take care of the full data needs. Many desks also had a small switch added in (I had them attached in a nice little niche built just for this purpose, so cables were out of sight). It was more complicated in my case because there were also additional network runs for a different network. This means that a few offices had an additional network connection.

Are you planning for extra runs for the future, or is there a justification for now?



When you say one Phone and two Lan, what is your justification (as in, what precisely did you say)?

Do you have this in nice graphs? I strongly recommend Visio. There are other products that are as nice, but I don't have have my list of these handy at the moment.

What is the current setup? Are there complaints about it?

BTW, I can talk about networks for a VERY long time. I live at the packet layer. Shrdlu == Layer 2/Layer 3.


IMHOP you should never run RJ11. 4 per CAT6 per location if allowed in budget? At least 3 CAT6. You do not know what the future has in store. Will you future phones run over you PCs? Will you have terminal services? Will they have be the CISCO's that have their own IP address and run Android?
You can run phone over the Cat6 and be ready for what ever comes at you. Network stops responding? Try the other plug and fix it later when you have a chance.

((Do as I say not as I do aka NOT RECOMMENDED )) In my case they decided to condense an office and the we did not have enough drops. We broke out the dumb switches.
Need a network printer at this desk? Dumb switch to the rescue.
Port stops working? Dumb switch until the problem is fixed.


If you have an IT area, you must have two network connections per desk, at least one phone, and one internet connection outside the network for software testing. Very often you will have multiple IT workers at a desk during development. My office connection had all of the above and we sometimes added a switch when we had 3 of us working together. The internet connection came in handy also for when a customer was in the office. (The customer couldn't sign into our network.)
