6.9 CHANGE, REM-M&C MENU
This menu allows the remote M&C port to be configured, and control of the unit switched between local and
remote. There are many different thoughts on how local / remote switching should be provided !
The text "(Rem M&C timeout=120s)" is only displayed if Give Away is selected on the menu described
below, it indicates that the Local option is not available until the timeout (which counts down when no
remote M&C messages are received) has expired. If Take Away is selected on the menu described below,
then there is no timeout and the user may take local control at any time.
6.9.1 Local Control TAKE AWAY / GIVE AWAY Selection
Under SERVICE (0), FACTORY PARAMETERS, REMOTE M&C the following menu is provided:
TAKEAWAY When selected the operator can switch between Local and Remote control at will
using the Local & Remote options on the Change, Rem M&C Menu.
GIVEAWAY When selected a subsequent screen is displayed which allows a timeout of up to
255 seconds to be specified. Normal switching between Local and Remote is then
by Giveaway philosophy, ie once in Remote M&C, local control is only granted by
a remote M&C command giving back local control. The timeout ensures that if the
remote M&C fails the operator can take local control when the timeout expires if
necessary. NOTE it does not automatically switch to local, it remains in remote
mode unless the local operator specifically selects Local after the timeout has
expired.
There is no option for Give Away without a timeout, otherwise the operator could find control of the modem
locked out if this option was active without remote M&C operating.
The subsequent timeout menu is as follows, its function is described above:
