We are trying to make the change from old analog telephone guys into the IP world. The application is radio mountaintops linked back to the central station by telco T1s and linked together with ethernet or T1 microwave links. The payload will be a few 64k IP voice links and that's it. The...

Found them finally, I was in a place that had them and they still had the label, Siemon M2-5W

Don't tell me they stopped making them. I looked at what Siemon makes and they are definitely on the front in the pictures. There was no picture of Suttle.

I have been having a difficult time locating a 66 block with a telco connector on the side but where the wires from the connector attach to wire wrap pins on the back rather than being punched down on the front. I would like this because it saves another set of jaws I could use for cross...

At this point, I am more seeking to be sure I understand what the definition of terms such as "-2 to +10 from 404 to 2804 Hz" actually is. This is the spec for the "attenuation distortion." Does this mean that we consider 404 to be 0 dB and measure how much 2804 passes relative to it? Or is...

Finding the actual phone bill or USOC code could be difficult, but I have managed to come up with some spec numbers using the clues you provided. The lines are point-to-point analog radio circuits. I am still having a little trouble understanding exactly what it is supposed to be, though. The...

Having recently inherited a radio system that has a lot of leased analog audio phone lines, many of which have some kind of trouble, I would like to know some kind of general specs that the phone company is obligated to maintain. It seems hard to find anything on Google, maybe because POTS is...

I was moving and extending a special service line at a customer's premises and I came across an office full of these gems which made it pretty easy for me to do my job. I was not able to figure out what they were when on site so I had to just use an ohmmeter and toner and figure it out. It...

I am in need of software and a cloud storage space that will synchronize a single directory and all its subdirectories, and mirror them on all computers. There are lots of offers out there but I want to find out what really works and is small and light. We have files that we need to have...

Thanks for that posting. That looks like what I was remembering but I am 90% sure that the one I remembered did not have any spots missing and the first 4 pairs were G/R Bk/Y W/Bu Br/O. It also had lamp and switch hookups for the 1a2 type systems. I bet that just tells me that there was no...

I have no idea where this post belongs so I am posting it here. We have 3 radio systems, and more on the way, that have remote terminals managed by custom DOS software provided by the manufacturer back in the 1990s. It will connect to the system controllers direct by serial cable, which works...

How will I go about finding a good, reasonably priced SIP provider? Call volume will be low. I will need something for outgoing, too, though it could be as simple as a Magic Jack, but it would be nice to have it display caller ID on a per-user basis so something IP would be nice there too...

It's done all the time for various reasons.

Thanks for the replies to all my questions Tommy. That is an interesting page but unless I am missing it, it does not include the "JK" color code or whatever it was called. I was thinking of the one that we still see that rarely gets past green/red and black/yellow since that's all the 4...

I saw once on the web a complete chart of all the color codes of a 25 pair JK cable feeding a 1A2 station, prior to the BOGBS/WRBYV color code we are now all familiar with. It had the voice pairs, as well as lamps, grounds, etc. but now I can't seem to find it. I wish I had saved it at the...

I'm not sure how much credence to give it, since it seems to have been drawn with a watercolor. Places you'd expect to see boundaries and skewed data, such as areas in the state of Nevada where the population is near zero, do not show up that way.

I have a modern Partner-18D phone on an old Partner II R4.1 system. I was not able to get it to program auto dial numbers onto the top 4 buttons, or program anything for that matter. When I select the button I want to program it beeps but nothing comes up on the display when it would normally...

I have a Partner II system R4.1 that I just put together from used parts. From my memory with Partner ACS systems, they used to display both the number and name of the calling party on both lines of the display on display phones. Now I have as my main phone a modern Partner-18D phone...

Are Rockport worth the hype? They always advertised that you can run a marathon in them. When I said my feet get wet I meant from sweat. But if I have to walk in a puddle to do the job, I will. My last pair clean up fine after that sort of thing. They just don't breathe quite as well as I...

Also, FYI, this is going to always be a very low volume setup. Probably never more than 15 DID numbers and one, maybe 2 DID trunks.
