    ABSTRACT: This Technical Reference (TR) provides the view of Telcordia on generic requirements for a Multiswitch Business Group (MBG) structure.

    The MBG structure provides for the creation of MBGs that extend the conventional Basic Business Group (BBG) and the Integrated
    Services Digital Network (ISDN) Basic Business Group (BBG-I) to multiple switches. An MBG can include the same categories of entities
    that are eligible to be included in a BBG-I: directory-number/call-type pairs served by ISDN interfaces (basic rate and primary rate),
    conventional lines, virtual private facilities supported by Signaling System No. 7 (SS7), and conventional private facilities. The
    feature requirements section of this document covers feature options, internal call-processing controls, signaling/message structure,
    administration/operations, and interactions.

    TR-NWT-000868 replaced TA-NWT-000868 and TA-TSY-000404.
