The Dynamode M-ADSL-FILTER-T is a full UK standard spec ADSL Microfilter for BT exchanges within the UK. Featuring high-performance circuits to keep telephone conversations at high quality and at the same time maintain optimum ADSL line speeds all the way up to ADSL2 8 Mbps specifications.
DC Characteristics All requirements for this specification can be met in the presence of all POTS loop currents from 0 mA to 100 mA. This Single In-Line filter can pass POTS tip-to-ring DC voltages of 0 V to 105 V and ringing signals of 40 Vrms to 150 Vrms at any frequencies from 15.3 Hz to 68 Hz superimposed on DC voltages in the range from 0 V to 105 V.
The DC resistance from tip-to-ring at the line port interface with the phone interface shorted, shall be less than or equal to 50 ohms for one filter.
