Fully Accessible System Topology (FAST)

Appendix C. FAST Activation Procedure

The CDM-625 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 purchase these unique, register-specific Fast
Access Codes from Comtech EF Data during normal business hours, and then load these codes
into the unit using either the front panel keypad or the CDM-625 Web Server (HTTP) Interface.
Contact a Comtech EF Data sales representative during normal business hours, or via e-mail to
sales@comtechefdata.com, to order the desired options.
FAST System Theory: FAST facilitates on-location upgrade of the operating feature set without
removing a unit from the setup. FAST technology allows you to order a unit precisely tailored for
the initial application. When your service requirements change, you can upgrade the topology of
the unit to meet these requirements within minutes. This accelerated upgrade can be
accomplished because of FAST's extensive use of the programmable logic devices incorporated
into Comtech EF Data products.
FAST Implementation: Comtech EF Data's FAST system is factory-implemented in the modem.
All FAST options are available through the basic platform unit at the time of order – FAST allows
immediate activation of available options, after confirmation by Comtech EF Data, through the
CDM-625 Web Server (HTTP) Interface.
FAST Accessible Options: Hardware options can be ordered and installed either at the factory or
in the field (see Table 1-1 for hardware option details). Depending on the current hardware
configuration of the unit, you can select options that can be easily activated on-site. The FAST
Access Code that is purchased from Comtech EF Data enables configuration of the available
hardware.
Table 1-2 shows the FAST and FAST-accessible hardware options available for the CDM-625. The
base CDM-625 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.
