CDM-700 High Speed Satellite Modem
Introduction
1.2.2 Turbo Product Coding (TPC)
The modem has Turbo Product Coding (TPC) available. TPC simultaneously offers increased
coding gain and lowers decoding delay. The TPC rates are:
Rate 3/4
Rate 7/8

Notes:
1. Rev. A and later units required for 1:1 and 1:N Redundancy. Initially released units are
not field upgradeable.
2. Check with factory for availability.
3. The PL/11509-1 is upgradeable to PL/11509-3 (functionality with a reflash of
PL/11509-1 module via the Gigabit Ethernet port.)
