Great video, very helpful info, appreciate you putting the effort into this! Helped me understand how these lines are working as I just inherited quite a bit of this infrastructure at a new job.
That's a good way to look at it. They are just not as clearly defined as a network patch panel so it's a lot more confusing for new phone techs. Bottom line is 1 pair / 2 conductors = 1 phone line / signal.
I'm looking for videos explaining analog speaker systems and 66 block? I have a speaker system where my speakers are plugged in to 4 plugs(tip,ring,24v,gnd)
Wow. I have never heard of running a speaker system through a 66 block. I don't know that I can help on that one sorry. I know just enough to get myself in trouble lol.
Thank you for the video. I have a question about the bridge clips. If you don’t have any could you just use a small piece of wire to jump the single over with?
Digital phone systems behave differently. You may not be able to get dial tone with a buttset. I would check the dial tone feeding into the Avaya to ensure you have an active line there. If you have dial tone to the system and the phones power up, but no phones on any extension will get dial tone, then there might be an issue with the system itself. Obviously, do the old "pull power and reboot" trick. If that doesn't work, pull power and re-seat all the internal cars. If it still doesn't work, unfortunately at that point, it's beyond my experience. Maybe one of the community here or Reddit can offer some further guidance.
After watching several videos i'm still having a hard time understanding the 66 0r 110 blocks and what it does with the PBX. Can you just wire up 16 wires from 16 rooms straight to a 16EXT PBX without any problems?
I'm going to be honest, I am not an expert on old school PBX systems. Here are a couple of things that I believe are true... A PBX system doesn't send a standard POTS signal to the 66 block. It sends a data and power signal to each extension so if you try to tone a jack, it's going to tone on the entire block because they are all interconnected. Typically you can't put a butt set on a PBX block to check for dial tone because it is sending a PBX signal to the block instead of a Tip and Ring signal. Wiring the extension on the block and on the jack is going to be specific to the PBX system. It may use one pair or two pair. It all depends on the brand and type of system. The bottom line is whatever pairs it's using are sending the data and power signals on the same pair or split between two pairs. Look at an existing extension that is working, and duplicate it for repairing, adding new, or replacing extensions. Hopefully, someone in the community will see your message and give you better information than I can.
