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

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
