I apologize if I confuse anyone with this, but I've never installed a merlin classic, I've only taken them out and replaced them....Here goes. I'm installing a customer provided 410 unit.
He had someone install the cabling and had it terminated on both ends(rj11's & 66 blk). I know I will have to replace the rj11's with 8 pin jacks, but what wires go where. I'll be using 8 pin modular jacks. Can I terminate a patch cord on the on the 66 blk and use the modular end to plug into the system. Again, what wires from the patch cord goes to the station cables on the 66.
