4.5.3. Return Loss:

4.5.3.1. Description:

The return loss of each filter under the specified conditions, either with or without the

ZHP-r attached, shall be greater than the value specified in page 6.

4.5.3.2. Test configuration:

Figure 3. defines the test configuration and the value of the test components that

shall be used for impedance measurement in the voice band for remote POTS filter.

Note :

1. ZHP-r = the impedance presented to the POTS connection by an ATU-R.

2. ZL = real impedance 600 Ω.

3. ZNL-r = 1330 Ω in parallel with the series connection of a 348 Ω resistor and a

100nF capacitor.

4. Test apparatus: Impedance Analyzer HP 4284A or equivalent.
