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
