opology (FAST) is an enhancement feature available in Comtech EF
Data products, enabling on-location upgrade of the operating feature set – in the rack – without
removing a CDM-710G from the setup.
This accelerated upgrade can be accomplished only because of FAST’s extensive use of
programmable devices incorporating Comtech EF Data-proprietary signal processing techniques.
These techniques allow the use of a unique access code to enable configuration of the available
hardware.
The access code can be purchased at any time from Comtech EF Data. Once obtained from
Comtech EF Data Customer Support, the access code is manually loaded into the CDM-710G via
the modem’s front panel keypad.
The FAST options are linked to three option registers:
•
Register 1 is for Data Rate options
•
Register 2 is for L-Band, Modulation type and Framing options
•
Register 3 is reserved for future options
When an unlock FAST code is obtained from Comtech EF Data, it is associated with a specifically
purchased unit (as identified by the unit’s unique serial number); the FAST access code unlocks the
pertinent options in all option registers.
