1658: 1668: 1647: 1678: 179:) is a specific type of multipoint link which consists of a central connection endpoint (CE) that is connected to multiple peripheral CEs. All of the peripheral CEs receive any transmission of data that originates from the central CE while any transmission of data that originates from any of the peripheral CEs is only received by the central CE. 577: 543: 214: 581: 547: 587: 497: 1630: 1602: 1597: 622: 202:
is a link that uses the public switched telephone network or other public utility or entity to provide the link and which may also be accessible by anyone.
