In order to operate in Turbo (TPC) Mode:

To operate in the 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, there are two additional FAST options available that permit operation up to 10 Mbps or 20 Mbps. Note that these are in addition to the base modem rate options.

In order to operate in 8-QAM mode:

The modem will require the TPC/LDPC Codec to be installed and have the 8-PSK / 8- QAM FAST option enabled.

For example, if LDPC operation at 20 Mbps, 8-QAM mode is required, the modem must be configured with the following:

•TPC/LDPC Codec hardware option

•Full rate variable FAST option

•High-Rate LDPC FAST option

•8-PSK /8-QAM FAST option
