Digital Data System (DDS) Multipoint Junction Unit (MJU) Requirements

Document Number TA-TSY-000192
Issue Number 02
Issue Date Apr 1986

    ABSTRACT: The Digital Data System (DDS) and similar systems offer, in addition to two-point circuit configurations, a multipoint circuit
    configuration using Multipoint Junction Units (MJUs). By using MJUs, a single communications channel can be shared among several
    stations that individually do not generate sufficient traffic to justify a full-time, full-duplex dedicated circuit.

    This Technical Advisory (TA) provides the preliminary view of Telcordia on generic requirements for a Multipoint Junction Unit used
    in the Digital Data System.

    When using TA-TSY-000192, you may want to refer to GR-63, GR-78, TR-NWT-000179, GR-282, SR-332, GR-357, and
    GR-1252 (replaced TR-TSY-000039).
