The SDM-300L3 Satellite Modem is designed to meet the requirements of the Satellite Digital
Communications industry. The SDM-300L3 Satellite Modem is a high performance, full duplex modem
compliant with IESS-308/309/310, FDC, and V.35 specifications, but also adds significant other features
in Closed Network modes. It offers variable data rates from 2.4 kbps to 5.0 Mbps, in BPSK, QPSK,
OQPSK, and 8PSK. Viterbi, Sequential, concatenated Reed-Solomon (RS), Trellis Coded Modulation
(TCM), and Turbo Product Coding (TPC) are provided as Forward Error Correction (FEC) options. EIA-
232, EIA-422, G.703, and V.35 (25-pin) interface types are available. The range of IF frequency
simultaneously covers 950 to 1750 MHz.
Burst Modulator Operation: 19.2 kbps and/or 57.6 kbps 1/2 rate QPSK
