I have a BT Freeway cordless telephone which decided to stop working after a call was cut off during lightning. At a geuss I would say that the line protection circuit did its job and protected the rest of the electronics, but blew itself up in the process. I am a digital engineer, so all these upity downity signals with little black components and capacitors confuse me. I have no circuit diagram which makes it more difficult. I have traced the line circuit to a couple of relays, through a zener back-toback pair and then a choke. The relays,chokes and zeners are OK but the unit still doesn't work ... ie no dial tone when taken off-hook. I think the cordless electronics are OK ... so I sort of think its the protection bits ?? Any ideas or help would be greatly appreciated. | Gary Cook , | Tel: 044 279 29531 ext 2615 | STC Technology Ltd, | e-mail: grc@stl.stc.co.uk | London Road, | Harlow, | *Disclaimer* - The views/opinions expressed above are | | Essex CM17 9NA, U.K.| not necessarily those adopted by STC Technology Ltd. | | Janet: grc@uk.co.stc.stl | Bitnet: grc%stl.stc.co.uk@ukacrl | | Uunet: uunet!mcvax!ukc!stl!grc | PSI%234237100122::grc |
