Glad to help - I want TBR 21 as badly as anyone! It's worth noting that the DC characteristics are unlikely to change in the short term, and the French started getting shirty when pestered about it...

I'm just starting the design of a universal DAA that hopefully will meet all TBR 21 requirements. All of the DAA circuits meet TBR 21, but I'm still a bit stymied by the holding circuit templated that requires limiting the line current to 60 mA when sourced through a 230 ohm resistor. I think the design is very close to meeting the template. I will know in next day or two. Again, thanks for the update. Regards, Duane
