Messing around with some field phones and am curious if I can use these around the house or if these need to be hooked into some form of switchboard
Yup I was a 31v,31u,31k,31c,31w-pretty much the whole 31 series.I am/was a 25C/31C, and while it was not my job, I did cross train enough to be dangerous.
I have only ever seen them hooked into a switchboard.
IIRC, the switchboard is what provides the "power".
The TA312s were still kept at the same time for direct. Remember that the 312s have batteries (Ds if IIRC)
The 954s were used with switchboards to be a phone network for a BN HQ.
Its been 13+ years (and we never used them even then) since I have messes with them, so I could be wrong or confusing them with another similar type of field phone.
Its been awhile, but I do seem to recall that we had two and four wire reels.I've read the model just before could be used as a simple field phone with a similar phone for sure. Read conflicting info on the 954. One guy said you need 4-wire and have to supply power. Another said he "didn't think" it could be done but wasn't sure.
For my field pone I just stripped the phone cord wires and hooked up the appropriate set to my field phone wire polls. For dialing out you would need some kind of dialing mechanism, but for receiving you just picked up and held in the talk button. For mute you release the talk button.The conversion to hook into a phone line involved gutting them, throwing everything inside away and adding off the shelf phone parts. May end up having to do similar if I can't find a way to make these talk to each other
