So here is the basics of what we are looking to do. I have a NIM 4E/M module installed in our ISR4300 router and we use this module largely for intercom like things. I've been tasked with integrating a piece of equipment which I'm not sure how to handle. If the device was capable of 4 wire Type V signaling I'd have this implemented already, but unfortunately the device being integrated only supports Type II. Attached is a screenshot from the manual. Any suggestions on how to wire this thing up or convert the port in question on the NIM 4E/M to a Nortel style port? Thanks.
