4.2 : HP-r Definition :
To facilitate the test of the splitter , the high pass data have to be taken into consideration.
Capacitors of 0.1uF on the NT-side are connected in series with 0.12uF capacitors in the tip-
And ring-line of the ADSL-output of the splitter itself(see block diagram above).
The equivalent circuit diagram of the NT-side is shown below :
0.1uF
0.47mH
100 ohm
0.1uF
4.3 : Electrical Specification
The low pass filter shall satisfy the following parametric limits with a complex impedance ZL
shown in this table across the Line side of this device .
The following requirement is specified for a single splitter.
