BT Ultimate 106 PABX

[AdrianUK]

Anybody have a schematic (ie. for the internal PCB) for this baby PABX?

I've got one which works fine except that it cant ring any of the extensions, I've tried resetting it to default but its still the same.

Looks like it has a problem with its ringing voltage generator.

Not familiar with the system but it appears you can disable all ringing via the programming http://www.toptelephones.co.uk/systems/userguides/06_BTUltimate106UserGuide.pdf Have a look at that, and if the problem continues bin it and buy another one . As for a detailed schematic you will probably be on google a long time.
