Maybe some cabling gurus can answer, but what are these used for? I've done a quite a few structured cabling jobs for customers, nothing more than wiring up houses/offices with cat5e terminating into wall-plates and patch panels. But where do these blocks (or wiring frames) fit in? I've seen them already installed described to me merely as the "phone system", but one client of mine had his 100baseT LAN on these blocks too. Someone quickly described them as an alternative to patch panels. Which I can see, one pair goes in one side, another pair comes in the other and they are connected...but what are the advantages in using blocks instead of patch panels? Any other uses for them?

110 and 66 block purpose...

For network cabling I would choose patch panel most every time: run a cable, terminate on a jack, plug in a patch cable to your network device. What could be easier? I have used a CAT5e rated 66 block but that was for a very small network with very limited space for equipment.
Predominantly I use 110 and 66 blocks to wire voice. Standard distribution cable for voice systems is 25, 50 or 100 pair run from a main distribution frame (MDF) to intermediate frames (IDF) and then dispersed on 4 pair cable to the telephone. In the IDF the wiring block allows simple cross connection of wires for ease in moves, adds and changes. Also, on your larger telephone systems you don't have modular plugs to patch into so at your MDF you need a wiring field to connect to your dial tone.

The description of distribution cable above is a good one, as well as terminating cabling out of telephone systems. Simply, they are a splice point, just a place to make a connection between multiple wires.
The 66 block dates way back I'm sure, and the 110 style is the better choice now.
A routine installation for us would have all the data cabling terminating on a patchrack, and all the phone wiring terminating on 110 blocks, with jumpers run to the other 110 blocks where the PBX/KSU wiring terminates.
It is only my opinion, based on my experience and education...I am always willing to learn, educate me!
