66block transdot 66 block.

A 66 block is a simple way to use wire-wrap connections with DPS RTUs. When telcos really want connections to stay in place, they use wire wrap. You'll simply punch down your alarm, analog, and/or control relay wiring to the 66 block, then connect the 66 block to the RTU using a standard amphenol cable (also available from DPS).
