Tone remote control over fiber

Post by arlojanis »

What would be required to change from using tone remote on a copper pair to using phone company fiber?

Dark Fiber (e.g. there is no service provisioned on the line) you will probably want to look at TC Communications TC8000 series boxes.

If they are providing you some sort of service I think the only thing Verizon is doing (at least in the north east) is T1 via FiOS. They supposedly have a ONT variant that has one or several T1 ports which they can then map to another Fiber T1. I don't think they can cross a fiber one over to a copper one, but, who knows. At that point if you are using normal RTNA/FDDA circuits you will need a channel bank to take the analog audio and send it over a T1 on both sides.

If they are giving you a metro ethernet circuit or something similar you can look at the RAD IP MUX, Cisco E&M, JPS NXU, or other Ethernet to E&M gateways to accomplish the task. There are several ways to skin this cat and each have their positives and negatives depending on your network topology....

The other monkey wrench in here is your radio system and how it is configured today may not tolerate the transport delays imposed by IP. In Fiber there is almost no delay and you can expect the circuits to be lossless audio circuits (e.g. -13 in is -13 on the other side) which makes alignment of your audio levels pretty easy.
