Punchdown Blocks, Tools & Accessories.
66 and 110, for phone and data

Also known as "terminal blocks," these versatile devices are used in telecom and data network installations where it is necessary to join wires together neatly. They are often used as a transition between a phone system's control unit, and the wires going to the telephone jacks; and as a demarcation point ("demark") between the phone company's wiring and the customer's equipment. PhoneGeeks.com stocks a variety of blocks, both industry-standard items and custom blocks designed to speed up the installation of Panasonic, NEC, Inter-Tel, Nortel and ATT/Lucent/Avaya phone systems.

There are two common families of punchdown blocks. "66" blocks are usually used for phone work, and "110" blocks are usually used for data... but either can be used for either.
