| patch panels for voice|
|Our facility is in the design phase of a new tower. Expert consultants recommend voice and data cabling on patch panels in closets, with cable management trays on outside of racks. On-site contracted telephone techs are screaming. They say it will not work for voice and will be a mess. Are they right or reluctant to change??|

This can work but requires some planning and thought. It also comes with additional cost as the PBX tails must be either broken out or terminated directly on the patch panels (typically 1 pair per port) and also the cost for patch cables.
Some PBXs have dedicated slots for the station cards while other have universal slots. The problem comes in when a slot that was wired for station card, using 1 pasir per port, must now be used for another function which would require a different pair arrangement or not needed in the patch panel field.
The only way to keep the flexability and still accomplish the desired effect is to fist cut down the PBX tails on blocks and then cross connect them, 1 PBX port per patch panel port, to tie cables feeding the voice patch panels.
Last thought on this is that if you are planning to use patch cables with plugs that are not 8 pin, make sure that the patch panel selected can work with 6 pin plugs without any damage to pins 1 & 8 of the patch panel.
