Well, to do what I want to do is 11 pieces for that last module, and the other CO lines to the other modules, it looks like about 9 pieces of about 10 feet. 8 station ports and 11 CO ports. The ones for the CO ports could be a bit shorter, 6-7 feet, the 8 for the station ports need to be 10 feet to be safe, I think. This will be especially helpful if I decide to get cables run to my collection of old phones. I'll need that last module for sure. Honestly, an 012E module would be more useful since I don't need 15 CO lines. But... I don't really need all those station ports either, and if I ever reconnect all the VoIP gateways for the C*NET, those CO ports might be useful. It's always in a state of flux. For now, I'd like to just get the module cabled the way it sits so I can just work off the blocks as I need to.
