A user-settable timeout controls for how long the
admin
user is logged in without any user
entry activity – when user entry is detected then the user session is extended by the
length of the timeout period. An
admin
user can also choose to log out of the modem,
which has the effect of closing the browser session and allowing another user to control
the modem.
View-only user login sessions do not use any timeout and are maintained until the
browser session is closed. They are also unaffected by whether the modem is under local
or remote control.
In Giveaway mode, control is passed to the first
admin
user that logs in. If an attempt is
made to log in as
admin
when there is already an
admin
user logged in, then the login will
succeed but the user will have view-only permissions, thereby ensuring there can never
be two users in control of the modem at the same time.
In order to allow a switch back to local control from Giveaway mode,
when there is no
remote admin user logged in
, the local front panel interface can gain control at any time
simply by issuing a command from the front panel user interface. While a remote
admin
user is logged in then the local front panel interface is restricted to viewing modem
settings only.
Once a local user has gained control in Giveaway mode, they can then change the
modem back to local control, thereby locking out remote
admin
users. Note that unless
the switch back is done, local front panel interface control will time out in a similar way to
remote
admin
users and thereby control may be taken away again by a remote
admin
user.
During the period between an
admin
user logging out and either another
admin
login or a
command being issued via the local front panel interface to gain control, no user is in
control of the modem.
Although there is no explicit login associated with the local front panel interface, there is
an implicit login when a key is first pressed. Conceptually, a user at the local front panel
interface is logged in as
admin
when in Giveaway mode
and there is no remote admin
user currently logged in
, otherwise the local front panel interface is logged in as a view-
only
user
. In Giveaway mode, the user at the local front panel interface can explicitly log
out by pressing the
Main
key.
7.1.3 Takeaway Mode
In Takeaway mode, either the user at the local front panel interface or a remote
admin
user can control the modem at any time. In this mode there is no restriction on the
number of
admin
users that can be logged in at one time. When the modem is switched
out of Takeaway mode to Local mode then all remote
admin
users will be automatically
logged out. When it is switched from Takeaway to Giveaway, then all but one instance of
admin
users will be automatically logged out. Although technically only one user is in
control at any time, control is relinquished as soon as a command is sent and therefore
different control requests from different users are simply interleaved with each other.
