Using the ISDN capabilities of the 5ESS(R) Switch, AT&T's first international ISDN trial is scheduled to start in Taiwan, Republic of China, in early 1989.
CCITT specifies that more than one ISDN user terminal may be equipped on a Basic Rate Interface. This configuration is commonly known as a point-to-multipoint configuration, or as a Passive Bus.
