6.  Glossary

     link station
         A link station comprises procedures and control information
         that coordinate the transfer of data between two nodes joined
         by a link connection.  All traffic over the link connection is
         from the primary link station to one or more secondary link
         stations, or from a secondary link station to the primary link
         station.

     primary link station
         The link station instance on a link connection that is
         responsible for the control of the data link.  There must be
         only one primary link station on a link connection.  The
         primary link station issues commands to one or more secondary
         link stations.

     secondary link station
         The link station instance on a link connection that receives
         commands from the primary link station and issues responses to
         it.

     switched line
         A telecommunications line in which the connection is
         established by dialing.  For switched lines, the SDLC startup
         sequence typically begins with a null exchange identifier (null
         XID).

     leased line
         A telecommunications line on which connections do not have to
         be established by dialing.  For leased lines, the SDLC startup
         sequence may or may not begin with an exchange identifer (XID).
         While there are interface (e.g., RS.232) differences between
         leased and switched lines, those interface differences do not
         map one-to-one with differences in the SDLC startup protocol
         (i.e., the interface and the SDLC protocol are independent from
         one another).

     point-to-point link
         A link that connects the single primary link station to single
         secondary link station.  A point-to-point link may be either
         switched or leased.

     multipoint link
         A link that connects the single primary link station to several
         secondary link stations.  A multipoint link may be either
         switched or leased.  Note: The physical interface signals for a
         multipoint link are different than for a point-to-point link.
