I've done voice and data for decades and really do not see much of a difference between them. Ethernet over Twisted Pair was developed to utilize existing voice telephone cables. I've run LAN connections on the violet pairs of a 25-pair cable feeding a 6-button KTS phone. No Problem!
I haven't started yet, as there have been delays, but I'm installing a roughly 200 position call center. Everyone gets a quad-4 ... four 4-pair "RJ-45" jacks to be used for whatever: corporate LAN, DSL LAN, digital telephone, single or multi-line analog telephone, even lamps and switches. All the cables will terminate on patch panels in the equipment racks. Each floor position laid out vertical on four 24 position patch panel.
The rep's phones are on an Avaya whatever. The lines from the Avaya terminate on connectorized 66 blocks -- running the cable involves attaching a pair of 25-pair connectors. Supervisor lines are local Centrex analog and arrive from the 1.1 on tie cables that I actually had to punch down. Both will be cross-connected to either 2-w jacks or 8-wire jacks, depending on whether or not they only use pair one. These 66-blocks are also connectorized, and Panduit makes both 1 pair and 4 pair connectorized patch panels.
In the equipment rack I'll be mounting (with some variation):
24 2-wire patch jacks (1 ru)
24-quad-4 floor cables on patch jacks (4 ru)
48 port LAN switch
24-quad-4 floor cables on patch jacks (4 ru)
48 2-wire patch jacks (2 ru)
24-quad-4 floor cables on patch jacks (4 ru)
48 port LAN switch
24-quad-4 floor cables on patch jacks (4 ru)
24 2-wire patch jacks (1 ru)
24 8-wire parch jacks (1 ru)
95%+ of all patch cables in the equipment racks will be 12" tip to tip running vertically between the LAN switch and a floor jack or a voice patch and a floor jack.
