TDM In UK Mode

This may be a stupid question but why should I set my TDM card and its modules to work in UK mode when the default mode seems to be working fine.

What does setting it to UK mode actually do from my experience so far is just beaks caller id.


anyone ?

It sets the DAA module of the card which sets the card to work wih UK line impedences. So you dont get impedance mismatches and echo.
