24、 clause contains European specific tests. Other performance requirements are for further study. 5.1.1 Repetitive Electrical Impulse Noise (REIN) test The test method shall be identical to the section 7.2.2 of DSL Forum TR-100 5.

26、I TS 105 388 V1.1.1 (2008-04) 7 5.3 Framing related requirements This clause contains European specific requirements related to framing parameter and framing parameter control. 5.3.1 Requirements for INP The mandatory values for Impulse Noise Protection (INP) for upstream and downstream transmission
27、 in European ADSL2plus transmission systems are 0, 1/2, 1, 2, 4, 8, and 16. The choice of values for INP_min and Delay_max can dramatically affect the resulting net data rate of the transmission system. This is illustrated in Tables K.3a/G.992.5 and K.3b/G.992.5 of ITU-T Recommendation G.992.5 1 for
28、 upstream and downstream transmission. 5.3.2 Requirements for interleaving memory From January 1st, 2009, the extended interleaving memory of 24 000 bytes, that can be negotiated as defined in ITU-T Recommendation G.992.5 amendment 3 4, shall be mandatory. 5.3.3 Requirements for S&D framing paramete
29、rs 5.3.3.1 Requirement for use in conjunction with 16 002 bytes interleaving memory The mandatory framing configurations are extended as follows: The mandatory downstream framing control parameter support for the mandatory latency path 0 is extended as follows (extension of table 7-9/G.992.3 amendme

Support of additional optional D0 values is indicated during initialization. All indicated values of D0 shall be supported. S01/11 S0 64. Support of these mandator
32、y S0values shall be indicated during initialization, through S0 min, with S0 min 1/11. Support of additional optional S0values is indicated during initialization, through S0 min, with 1/16 S0 min 1/11. All values of S0, with S0 min S0 1/11, shall be supported. 5.3.3.2 Requirement for use in conjunct
33、ion with 24 000 bytes interleaving memory From January 1st, 2009, in conjunction with the 24 000 bytes interleaving memory defined in clause 5.3.2, the mandatory downstream framing control parameter support for the mandatory latency path 0 will be extended as follows (extension of table 7-9/G.992.3
34、amendment 1 7). The values in the table shall be supported in the transmitter and receiver.
