If I'm reading this right you're talking about a patch cable used to cross-connect from a 110-style termination block to a 8-position, 8-conductor modular port (aka RJ-45).
If so you only need to request a 110 to RJ-45 patch cable from any distributor, they'll know what you're talking about. Make sure you tell them the category cable, how many pairs you want on the 110 side, and the pin-out you want for the RJ-45 end.
Hope this helps.
