Document Number TA-TSY-000281
Issue Number 02
Issue Date Jun 1986

    ABSTRACT: A Digital Cross-Connect System (DCS) is an intelligent (processor controlled) digital terminal that provides the basic ability to
    access and rearrange DSO channels of digital bit streams [DS1 (1.544 Mbps), DS1C (3.152 Mbps)] through its switching network. With the
    added capabilities of a Digital Multipoint Bridging (DMPB) feature described in this Technical Advisory (TA), a DCS provides the
    capability to connect DSO channels in voice multipoint arrangements (conference circuits) and in voiceband data multipoint arrangements
    (polling circuits).
