1 IETF Meeting #62 New Generation ADSL MIB Baseline Text Proposal Presented by: Moti Morgenstern, ECI Telecom draft-ietf-morgenstern-ngadsl-00.txt

2 IETF Meeting #62 draft-ietf-morgenstern-ngadsl-00.txt 2 Introduction “draft-ietf-morgenstern-ngadsl-00.txt” is presented to the IETF as a proposed baseline for the NG-ADSL MIB.  NG-ADSL MIB is also known as ADSL2 MIB The draft  Is based on ITU and its amendment.  Usually takes DSL Forum’s TR-90 as a reference.  …Not final People may eventually choose to migrate from the current ADSL MIB (RFC 2662) to the NG-ADSLMIB.

3 IETF Meeting #62 draft-ietf-morgenstern-ngadsl-00.txt 3 Textual Conventions There are plenty of textual conventions (TCs) in the current document. Probably, most of those TCs will be relocated to form a separate document.

13 IETF Meeting #62 draft-ietf-morgenstern-ngadsl-00.txt 13 adsl2LineConfTemplateTable Originally the structure of the template in TR-90 is  Pointer to ADSL Line Spectrum Profile  Pointer to ADSL Line Service Profile The Line Service Profile is actually a frame May include multiple instances of channel profiles In this draft the structure is  Pointer to ADSL Line Spectrum Profile  Channel 1 configuration Pointer to a channel profile Rate Adaptation Ratio Downstream/Upstream  Same for Channels 2-4 The advantages of this approach:  Reduces the number of profile layers  Reduces the number of different channel profiles required
