I'm looking an installation that has an old patch bay that seems to have a set of analogue phone lines going in - being mixed with Internet style RJ45 connectors into what appears to be a regular internet switch.

the suggestion is the outputs are going to modern phones needing more power than is available from the analogue PBX

Does this sound a common practice?  Is this a way of migrating to VOIP phones?

 
That could be 2 things, PBX phones using patch panel cabling, which is standard practice in a business environment, or VOIP phones on the same cabling. If the phones patch to a switch then they are VOIP phones - a PBX would supply more than enough power for a handset.

All fine so far.

An RJ45 connector is an RJ45 connector. What makes this one look more like an "internet style" one?

into what appears to be a regular internet switch.


What's one of those?

That makes no sense. Just to break it down;

the suggestion is the outputs are going to modern phones


Outputs? Of what? What are "modern phones"?

needing more power than is available from the analogue PBX


Phones don't really need much power, if they are compatible with the PBX then that means they draw the power required and the PBX supplies it. You will not find a phone that "draws too much power from a PBX".

Is this a way of migrating to VOIP phones?


No, or yes. Not really sure what you are trying to do. To migrate to VoIP you can get rid of your old analogue lines/PBX and just put VoIP phones on the desk.

And "power over internet" is not a thing, and probably never will be. Maybe you mean PoE (power over ethernet), but then you never mention this in your post anywhere.

The PBX has only analog jacks being fed through the patch bay - and then through separate switch 

 
The PBX won't use a switch unless it's VOIP. Maybe it's mixed analogue and VOIP on the same panel?
