Not sure exactly which forum to post in, so please move if you don't agree. There is a FTTC service on the line and I think an answer reflecting modern lines and equipment, and any adjustments that could make to previously issued advice, would be useful to others.
I would like to know if REN numbers are still a necessary consideration on a BT line.
I have today purchased a new telephone, and moved the old one (with real bells, needed the ring wire connected) onto a spare extension socket, so now the setup is like this:
Master socket with FTTC faceplate: 1 telephone with electronic ringer (REN=1) plus data extension to FTTC modem / BT Home Hub 3 (Does this have a REN value?)
Extension 1: 1 telephone with electronic ringer (REN=1)
Extension 2: 1 telephone with real bell ringer (REN=1)
Extension 3: 1 DECT cordless telephone (REN=1)
Extension 4: 1 telephone with electronic ringer (REN=1; although very difficult to read the sticker!)
Will this number of devices on the line cause problems (I recall a limit of 4.0 previously)?. All 'phones do appear to ring and work fine.
Even if this would be above the theoretical maximum, how can I tell if there is a problem; what will happen and is this a definite thing to avoid?
Thanks,
David
