The working group will define: 1. A set of managed objects to be used for management of newer versions of Digital Subscriber Line (xDSL) as defined in ITU-T Recommendation G.997.1 (02/2006). 2. A set of managed objects to handle the bonding of xDSL lines according to the ITU-T Recommendations G.998.1 (ATM), G.998.2 (Ethernet) and G.998.3 (TDIM). A common MIB module will be developed to handle the common objects and three specific MIB modules will be developed to handle the three separate layer-2 technologies. Use will be made of the ifStack and ifInvStack Tables defined in RFC 2863 and RFC 2864 respectively. Use will also be made of the ifAvailableStack and ifInvAvailableStack tables as defined by the Hubmib WG. The MIB modules defined by this group will be generated using SMIv2, will be consistent with the SNMP management framework, and will describe the relationship of the objects defined to existing MIBs such as those described in other work products of this Working Group, the interfaces MIB, the Ethernet MIB modules and the AToM MIB. The working group will consider the input of the DSL forum and the ITU in the definition of these MIBs.
