CDM-760 Advanced High-Speed Trunking Modem
6.2.8.2 (FAST:) Demo-Mode
FAST Options Demo Mode: Off
Time remaining: 29:23:59:50
FAST Options Demo Mode allows access to ALL CDM-760 FAST options for 30 calendar days. On
the top line, use the  arrow keys to select Demo Mode as Off or On. Press ENTER. The
bottom line displays the Time remaining – the time format is DD:HH:MM:SS (days, hours,
minutes and seconds. Note the following:
• The time count decrements only when Demo Mode is turned On. Demo Mode may be
turned on and off an unlimited number of times until the full 30 calendar days have expired.
•
Once the timer decrements to 00:00:00:00, FAST Options Demo Mode may no longer be
enabled. Your modem will still function with the purchased FAST enabled features.
If the Demo Mode timer reaches 00:00:00:00 while the modem is running a FAST
feature that is not a purchased FAST feature, the modem will fall into an invalid
state, turn off its carrier, and revert all settings to factory default settings.
6.2.8.3 (FAST:) CnC
FractionalCnC:Time Remaining: 90:00:00:00
Time Remaining Refills In 364:23:59:31
Full CnC License is installed.
Fractional CnC is common in 1:1 or 1:N redundancy systems where the primary modem is
running fully operational (i.e., FAST-activated) CnC, and the backup modem(s) has FAST-
activated Fractional CnC.
Fractional CnC allows 90 full calendar days of CnC usage in a calendar year. This lowers the cost
of the modem but does not allow for constant, round-the-clock CnC operation.
As per the previous screen examples, if Fractional CnC is not installed in the CDM-760, the
modem displays a message that no CnC license is installed and provides "time remaining" and
"time remaining refill" timers; or that a Full CnC license is installed and the screen displays no
timers. Note the following:
• FractionalCnC: Time Remaining – This is the amount of time, in the form dd:hh:mm:ss
(days: hours:minutes:seconds), that that the modem can be run in CnC mode. This counter
decrements under the following conditions:
o The modem has a FAST-activated Fractional CnC license
o The modem is powered ON
o The modem's Tx is ON
o The modem is in standalone mode or in 1:1 redundancy configuration and is Online
