24 Local access control management
24.1 Purpose
This chapter provides procedures to manage Local Access Control (LAC).
24.2 Overview
NE control can be managed by an Operating System (OS) using the LAC feature.
LAC management provides a mechanism to prevent multiple users sending write
commands to the NE simultaneously.
The OS manages the NE until a request to manage the NE is received from a craft
terminal (CT) and granted. The request is initiated by the CT user. The OS answering
yes to the request transfers management of the NE to the CT. The LAC request can
be denied by the OS (if for example the OS is in a state of recovery from a temporary
loss of communication with the NE).
The request to manage starts a timer. If the OS doesn't answer a CT request to
manage in a predefined time, the CT automatically becomes the NE manager. The
predefined time is user provisionable.
The manager currently managing the NE is indicated on the CT screen by the Lock
control status (Local Access) granted icon. See Figure 102. When local access is
denied on the CT is indicated by the Lock control status denied icon. See
Figure 100.
