CDM-750 Advanced High-Speed Trunking Modem Revision 2
Front Panel Operation MN-CDM750
5–65
Fractional CnC:Time Remaining cannot be reset or refilled in the field. Once the
timer has run out, your only options are to:
1) Upgrade the modem to a full license
2) Wait until “ Time Remaining Refills In” reaches 00:00:00:00.
Using Fractional CnC is not a normative mode of operation. To best inform
you
that your modem is running Fractional CnC (i.e., the “FractionalCnC:Time
Remaining” counter is actively decrementing), your modem does the following:
•
The RED Unit Status LED on the front panel of the modem will blink on
and off.
•
The modem generates an Event in the Event Log every 12 hours indicating
that Fractional CnC is running.
•
When connected to a 1:1 redundant switch, every 12 hours the modem
generates a phantom fault, allowing the Full License CnC modem to return
online if its fault has cleared.
