Discuss 3 phone points in the UK Electrical Forum area at ElectriciansForums.net

Only 2 & 5 needed these days connecting terminal 3 can be a cause interference which reduces broadband speed

If you want to connect terminal 3 and your broadband speed reduces then BT suggest fitting an I-Plate which disconnects the ring wire
 
I have a quick of topic sort of ish question, ive done these before with 3 phone sockets.. What is the maximum Master to Slaves you can have on one? Is it unlimited or can you actually have like Master - > slave 1 > 2 > 3 > 4 > 5 > 6... 7 Telephone points ;P !
 
There is no limit on the number of line jacks you can install your limit is the total number of REN (ringing equivalence number) connected to the line the maximum is 4 before problems occur. All telephone equipment has a REN value most phones are 0.5 but some can have a REN of 1

Got a job to do for a customer next week where I'm expecting problems as sky are insisting all their boxes are connected to a telephone line the customer has 7 boxes plus the phones
