Comtech EF Data’s SLM-5650A Satellite Modem is compliant with the strict requirements defined in MIL-STD-188-165A, modem types I, II, IV, V and VI for applications on DSCS, WGS and commercial satellites. Data rates from 64 kbps to 155 Mbps and symbol rates from 32 ksps to 64 Msps are supported. The modem provides standard MIL-STD-188-114 (EIA-530 / RS-422), and EIA-613 (HSSI) serial interfaces, and can be optionally configured to support G.703 and Low Voltage Differential Signaling (LVDS) serial interfaces. It can also optionally be equipped with a 4-port 10/100/1000Base-T Ethernet Network Processor module that supports switching, routing and advanced Quality of Service protocols.

The SLM-5650A can be integrated with the Vipersat Management System (VMS) to provide fully automated network and capacity management. An AES-256 TRANSEC module, compliant with the FIPS-140-2 NIST standard is also available as an option. All traffic (including overhead and all VMS control traffic) is encrypted when using the TRANSEC module. Advanced forward error correction (FEC) capabilities are aComtech EF Data standard feature. Viterbi, Trellis, Concatenated Reed-Solomon, Sequential, and Turbo Product Codes are all supported. Advanced FEC and modulation capabilities are integrated with the revolutionary DoubleTalk® Carrier-in-Carrier® bandwidth compression allowing for maximum state-of-the-art performance under all conditions. This combination of advanced technologies enables multi-dimensional optimization, allowing satellite communications users to:

• Minimize required satellite bandwidth
• Maximize throughput without using additional transponder resources
• Maximize availability (margin) without using additional transponder resources
• Enable use of a smaller BUC/HPA and/or antenna
• Or, a combination of the above to meet specific mission needs the IF interface supports 52-88, 104-176, and 950-2000 MHz frequency ranges.

The SLM-5650A is interoperable with the OM-73, SLM-3650, MD-1352(P)/U (BEM-7650), SLM-7650, SLM-8650, CDM-570, CDM-600/600L, CDM-625, CDD-562, CDD-564, DMD20, and DMD2050 satellite modems.

DATA INTERFACES
The modem supports EIA-530 (RS-422), EIA-612/613 (HSSI) as standard features. Optional interface modules are available to support G.703, LVDS serial, or 4-port Gigabit Ethernet interfaces.

TRANSEC MODULE
An optional transmission security (TRANSEC) module provides bulk AES-256 encryption/decryption in accordance with the FIPS-140-2 Level 2 specification. The TRANSEC module encrypts all traffic sent over the air, including data traffic, overhead channel and Vipersat Management System messages (if present).

TURBO PRODUCT CODING
Turbo coding provides superior error correction performance over Viterbi, Trellis and Reed-Solomon FEC. The SLM-5650A Turbo Product Coding is compatible with Intelsat IESS-315 and Comtech EF Data’s CDM-570, CDM-600, CDM-625, SLM-3650, SLM-7650, DMD20, and DMD2050 Satellite Modems and the CDD-562/564 IP Demodulators.
