    DESCRIPTION
      "The objects in this MIB module are used to manage the
      multi-pair bonded xDSL interfaces using ATM inverse
      multiplexing, as defined in ITU-T Recommendation G.998.1
      (G.Bond/ATM).

      This MIB module MUST be used in conjunction with the GBOND-MIB
      module, common to all G.Bond technologies.

      The following references are used throughout this MIB module:

      [G.998.1] refers to:
        ITU-T Recommendation G.998.1: 'ATM-based multi-pair bonding',
        January 2005.

      [TR-159] refers to:
        Broadband Forum Technical Report: 'Management Framework for
        xDSL Bonding', December 2008.

      Naming Conventions:
        ATM   - Asynchronous Transfer Mode
        BCE   - Bonding Channel Entity
        BTU   - Bonding Terminating Unit
        CO    - Central Office
        CPE   - Customer Premises Equipment
        GBS   - Generic Bonding Sub-layer
        GBS-C - Generic Bonding Sub-layer, CO side
        GBS-R - Generic Bonding Sub-layer, RT (or CPE) side
        PM    - Performance Monitoring
