this object must be initialized to zero.
Management: If the value of
sdlcLSStatsRetransmitsOut grows over time,
then the quality of the serial line is in
question. You might want to look at
decreasing the value for sdlcLSAdminMAXDATASend
to compensate for the lower quality line."

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.
Synonymous with multidrop line.
