This attribute indicates the mode in which the RouteSelector is
currently operating. The two possible modes are automatic and
manual.
In the automatic mode, a route request message containing the route
request data is originated by a PORS VC and sent to the
RouteSelector. RouteSelector then selects a route or gets a manual
route and returns its description in the selected route description
data in the selected route message back to the PORS VC.
In the manual mode, the RouteSelector allows the operator to
modify the parameters in the route request data (except for the
manual path profile reference), and to initiate route selection using
that data. When RouteSelector selects the route it displays its
description to the operator.
Note that even when operationMode is set to manual,
RouteSelector handles route request messages originated by
services' VCs in the same way as it does when operationMode is
set to automatic.
