This causes the modem to ignore loss of demod lock, which could otherwise
cause a 1:N changeover.
This causes the modem to ignore loss of incoming data to the modulator that could
otherwise cause a 1:N changeover. Setting both transmit and receive fail switchovers to
Off
effectively configures the unit to switch on unit faults only and ignore all traffic faults.
7.3.3.4 Edit-Memories
Menu
This menu contains the following options:
•
Store.
This allows the current M&C configuration to be stored to a named
configuration memory for later use. Up to 20 configuration memories can be created
(more may be stored if memory allows). The memories are non-volatile and will
persist between successive power-ups of the modem. Configuration memories can be
assigned any desired name using the alphanumeric keypad.
•
Recall.
This allows a previously stored configuration to be selected and used in place of
the current configuration.
•
Erase.
This option allows configuration memories to be deleted.
Note that one configuration memory, namely
LOAD_DEFAULTS
always exists. When this
is recalled then it has the effect of setting the modem back to the factory defaults.
(Although the
LOAD_DEFAULTS
memory also appears under
Store
and
Erase
, these
operations have no effect on this particular configuration memory.)
Note that there are restrictions on what characters can be included in the configuration
memory names. Only the letters of the alphabet and numerals should be used.
