The working group will define: 1. 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 ifCapStack and ifInvCapStack tables as defined in RFC 5066. The Broadband forum TR-159 will be used in the definition of these MIBs. 2. The working group will develop a set of managed objects as an optional extension to RFC 5650 that shall provide an alternative approach, known as the "Vector of Profiles", for the configuration of DSL lines. The Vector of Profiles MIB will be based on the Broadband Forum TR-165 document. The ITU-T G.997.1 will also be considered in the definition of this extension. 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.
