Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document is part 2,

15、cification of the high pass part of VDSL/POTS splitters for use at the Local Exchange (LE) and the user side near the Network Termination Point (NTP)“; Sub-part 3: “Specification of VDSL/ISDN splitters for use at the Local Exchange (LE) and the user side near the Network Termination Point (NTP)“.

16、TE: The choice of a multi-part format for the present document is to facilitate maintenance and future enhancements. The present document is fully in line with initiative “eEurope 2002 - An Information Society For All“, under “The contribution of European standardization to the eEurope Initiative, A
17、 rolling Action Plan“ especially under the key objective of a cheaper, faster and secure Internet. ETSI 5 ETSI TS 1 O1 952-2-3 VI .I .I (2003-03) 1 Scope The present document describes requirements and test methods for DSL splitters. The present document specifies requirements and test methods for V
18、DSL over ISDN splitters to be used at the Local Exchange and at the user side near the NTP. This present document is derived from TS 101 952-1-3 4, describing requirements for ADSL over ISDN splitters. A consequence of this is that the filter described in the present document can only be applied to
19、VDSL over ISDN in an environment where the VDSL pass band starts around 138 kHz. The low pass and high pass filters described in the present document are intended to be used in conjunction each other, and with a practical VDSL transceiver impedance defined in TS 101 270-1 3. If VDSL splitter parts a
20、nd VDSL transceivers are combined which are not intended to inter-operate, then severe problems of incompatibility might arise. There is at least one more variant under study for the high pass filter, and for the related low pass in conjunction with the relevant VDSL impedance: Where the VDSL passba
21、nd starts at a frequency higher than around 900 kHz and the VDSL transceiver impedance is close to the nominal design impedance above this frequency, for instance in a cabinet deployment where the band below around 900 kHz is not used in order to be spectrally compatible with ADSL from the Central O
