DEFINITION
“A topologicalLink information object repre-
sents ‘a link provided by one and only one
server trail, in a client layer’ (G.852.2 defi-
nition).
This topologicalLink information object type
is a subtype of the networkInformationTop
information object type.”
ATTRIBUTE
signalIdentification
“The signalIdentification describes the
signal that is transferred across the link.”
linkDirectionality

“The linkDirectionality attribute charac-
terizes the ability of the associated
resource to carry traffic in one, two, or
undefined direction.“
INVARIANT
inv_directionality
“The linkDirectionality attribute value
cannot be set to undefined.”
