John, A BT3 refers to the impedance reference network per NZ Telecom PTC 200. It is a complex network of 370 ohms in series with parallel components of 620 ohms & 310 nF. Peter Wheeler +64-4-498 9708 and/or Richard Brent should be able to answer any questions you may have. Regards, Daren E. Allen

A client in New Zealand says it is a standard(?) he must meet. Something to do with line impedance for xDSL modems. Sorry for the sketchy details, just trying to get an early start. Thanks John Honeycutt
