integrated services digital network
Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the digitalised circuits of the public switched telephone network. ...
(ISDN) interface used in private networks. It is derived from the
UK0-Interface used in public

Network, networking and networked may refer to:

.
In public networks, the maximum cable length of an U bus is between 4 and 8 km, and the maximum length of an
S0-bus is 900 meters for Point-to-Point configuration and about 150-300m for point-to-multipoint configurations. The U
p0-bus has, depending on cable quality, a reach of between 2 and 4 km, far more than the
S0-bus. This allows the use of ISDN telephone equipment in large private networks. Unlike the
S0-bus, the U
p0-bus runs at half duplex; that is, both sides alternate in sending and receiving.
While the
S0-bus allows for several ISDN device connections (up to 8), the U
p0-bus can connect only two devices, one at each end of the cable.
