Operator - The person who uses the Operator Interface to manage
the network. There are six levels of operators, each with different
levels of access to the Operator Interface. The operator is
identified by an operator ID of up to eight alphanumeric
characters.
Operator Console - The terminal used to communicate with the
Operator Interface on the node. Physically connected to the RS-
232C interface of the processor module.
Operator ID - Operators are identified in the Operator Interface by a
name up to eight alphanumeric characters. The operator name is
used to log into the Operator Interface and has session
parameters associated with it through the operator profile.
Operator Interface - A menu/query system consisting of four levels:
(1) Prolog Procedure menu, (2) Functional Area menu, (3) Action
menus, and (4) Object menus.
Operator Profile - A file containing the default session parameters
associated with a specific Operator ID and stored in the
configuration database. If an operator profile is not updated,
changes to the session parameters will be in effect only during the
current session. Upon updating an operator profile, the session
parameters will be in effect during subsequent sessions under the
same operator name.
OPG - operator equipment group
