See Appendix C. FAST ACTIVATION PROCEDURE for further information.
FAST Accessible Options
Hardware options for basic modems can be ordered and installed either at the factory or in the
field. The operator can select options that can be activated easily in the field, depending on the
current hardware configuration of the modem. A unique access code enables configuration of the
available hardware.
The base CDM-600/600L unit is equipped with Viterbi, Sequential 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, the base unit does include
EDMAC and AUPC.
The following table shows the available FAST and FAST-accessible hardware options:

In order to operate in Turbo (TPC) Mode: To operate in the Low Rate range (up to 5 Mbps), the
modem requires any of the three Codec cards to be installed.
To operate in the Mid- or High-Rate ranges (up to 10 or 20 Mbps), the modem requires either the
High Rate TPC Codec or the TPC / LDPC Codec to be installed.
In order to operate in LDPC Mode: The unit will require the TPC/LDPC Codec to be installed. In
the base configuration this will provide LDPC up to 5 Mbps. In order to operate at higher data rates,
