4.2. ZADSL-I definition: 2

In many of the tests with ISDN-BA frequencies, the ADSL port of the splitter is terminated

with an impedance called ZADSL-I. This impedance model as shown in figure 1, represents

the input impedance of the ADSL transceiver as seen from the ADSL port of the splitter,

and does not include the blocking capacitors. The model is intended for splitter

specification in the context of the present document. The purpose of this model impedance

is for splitter specification, it is not a requirement on the input impedance of the ADSL

transceiver.

Note: ZADSL-I does not include the blocking capacitors CB =27 nF
