Phones ?

[stidge]

hi all, sorry youve probably been asked a thousand times. I have wired 1 x master feeding 4 slave phone sockets. Total run approx 30 metres.have got signal at master and no 1. have had them all working individually but were not all connected to plate(just twisted pairs). Have been told too many slaves,too long run etc etc any advice please

1st. make sure the master socket is a master ( capacitor) then . incoming line to 2 & 5 on master. link 2,3,5, from master to all slaves. should work OK.

hi

i've not had much to do with phones other than connecting the odd slave etc. I have heard many times about something called REN, which I think is Ring Energy Number???
This limits the amount of slave and lengths i think. However I have had it a couple of times I have had the odd slave working and master not or both not etc etc and it turned out to be the types of phones used in the "system"

try different phones if available as this took me ages to work out?

REN = ring equivalent number.

What it meant was each phone was equal to 1 so you could have a max of 4 phones or 3 phones and 1 answer phone ont he circuitbut with the advent of digital phones I don't think it applies anymore
