Chapter 5. FAST ACTIVATION PROCEDURE
The CDM-625A Advanced Satellite Modem incorporates a number of optional features. In order
to permit a lower initial cost, you may purchase the unit enabled with only the desired features.
If you wish to upgrade the functionality of a unit at a later date, Comtech EF Data provides Fully
Accessible System Topology (FAST), which permits the purchase and activation of options
through special authorization codes. You may contact Comtech EF Data Product Support to
purchase these unique, register-specific Fast Access Codes, and then load these codes into the
unit using either the front panel keypad or the CDM-625A HTTP (Web Server) Interface.
FAST Accessible Options: Table 1-2 shows the FAST and FAST-accessible hardware options
available for the CDM-625A. The base CDM-625A unit is equipped with Viterbi and Reed-
Solomon codecs. It offers BPSK, QPSK, and OQPSK modulation types, and data rates up to 5.0
Mbps, with all interface types. While it is limited to Closed Network operation, it also includes
EDMAC and AUPC.
