<P>Hi</P>
<P>I am building a new office network for around 600 staff. One of the requirements is to have cat6A cabling to the desktop as the business wants to plan ahead. It was not feasible to have 6A at this stage as the coms rooms limitations and costs but gig to the desktop is in. This cable plant will be long term investment and all desktops/laptops are gigE already. We will use gig capable phones. I think even though an organisation may not have GIG requirement today but its the way forward. As far as the 6509 backplane limitation there is a general oversubsription/contention of 1-20 to 1-50 for access ports. I am yet to see an access layer design with one is to one for uplinks. 10 G server farm and uplinks are becoming commen with hardware prices going down.</P>
<P>6500 series roadmap has plans to upgrade the backplane to 1440 Gbps and we may see higher densities of ports so we can see more 10G ports per card from the current no of only 4<BR><BR>Regards </P></DIV>

"behind" the phones would need GiGE, then something<BR>>"at<BR>>the other end" may require such, as well. In an office environment, though,<BR>>at the other end is either a server (file shares), or a connection to a<BR>>remote site. The former, then, would require itself at least a 10 GiGE<BR>>connection to be able to support those workstations, which is not available,<BR>><BR>>and - based on regular office applications - it is hard to believe that<BR>>they,<BR>>themselves would be able to push this much on the wire (I liked/appreciated<BR>>the idea of medical imaging, but this is not our case). The latter would<BR>>obviously find its limitations in the bandwidth available inter-sites, so<BR>>that is not an argument, either;<BR>><BR>>- video for the phones: this is not the type of phones they are getting, to<BR>>begin with. Under the
assumption of future (not near) deployment of<BR>>video-based ones, I would expect a drop in price for the modules, and the<BR>>only restriction in such a case between the 4500s we were suggesting, and<BR>>the<BR>>6500's they would like becoming the backplane capacity (96 Gbps now for<BR>>4500's vs. 720 Gbps for the 6500's). In this [unlikely] scenario I would<BR>>expect higher capacity backplanes being made available for the 4500's, by<BR>>the<BR>>time of "must have video on every phone in the office".<BR>><BR>>To simplify my original question: does anybody have real life examples of<BR>>GiGE<BR>>deployment for office environments, with GiGE-based phones?<BR>><BR>>Thanks again,<BR>>Stefan<BR>><BR>>On Tuesday 01 August 2006 20:13, Rob Gault wrote:<BR>> > What about the switch port in the phone, are you connecting pc's to
