We are in the process of building another building.  We decided to provide telephone service via our existing Hipath 4000.  Using TDM phones connected via skywalk to the new building.  The contractors have provided a cabling scheme using all CAT 6 cabling terminated to patch panels located in the data closets.  They also wanted the riser pairs punched down in this fashion.  This is a totally new concept in our environment, because we are used to the traditional "telecom" way of doing things by using 66 blocks or 110 blocks for termination.  What I am looking for is any thoughts any body has out there with this configuration.  Advantages?  Disadvantages?  Any help would be appreciated.

RE: Wiring?

Hello 30ptbuck,

You might consider posting this on the Cabling forum.

To summarize

The advantages are that this standards compliant method of doing this allow quick and easy changes since the Layer 1 infrastructure is interchangeable between between voice and data.

The down side is that unless you break the system and make it no longe rcomply wiht the standards, it is hard to use different pairs int he same jacket for different functions.

For example you might want to run a voice pair and 2 pairs for 100Base-T in the same jacket. To do this and be at least semi-compliant wih the standards you'd use "splitter dongle gizmos" to break out the pairs at the ports int he closet and at the jack. These gizomos are available, but there are not an elegant solution. (The elegant part is having the the infrastructure be a known quantitiy without cusotmization).

I'll watch for a vigorous discussion among various proponents of the two concepts over on the cabling forum, here:


have fun

RE: Wiring?


If you want another vigorous debate ask about the grounding and bonding considerations.

While it is true the cable never goes outside (I assume it goes on the inside of the skywalk) it is still running between buildings and probably requires protectors at either end.

The AHJ (authority having jurisdiction, e.g. local inspector) gets the final call on this, of course.


RE: Wiring?

We went through a simular debate when opening a new building. The contractor's justification for cat 6 was for VOIP. Well, VOIP phones work inline -- Why do you need another data jack? Patch panels for voice also take up way more room, and if you need 2 telephones in one location make a mess. So we just ended up going with Cat3 and blocks.
