If the IDC strips are enclosed in a plastic connector block, with (usually) 8 or 10 contacts per block which mount into a white plastic base, with space for 50 contacts per row (25 pair), then you likely have a "110" block. Be careful, though; there are other structured wiring systems that are similar but use different tools. The 110 blocks are usually made from white plastic, while some of the alternatives are beige (for Nortel-flavored), for instance. louie
