1.2 Functional Description

Figure 1-3. SLM-5650C / SLM-5650C-ODU Block Diagram
Figure 1-3 depicts the functional block diagram for the SLM-5650C and SLM-5650C-ODU. Both modems have been designed to accommodate a wide range of currently required features, and to support both near- and lo n g-term advances in software-defined radio technology as well as advances in FEC technology.
The user has the ability to:
Utilize an extensive array of built-in test capabilities
Easily upgrade the modem’s operational capabilities in the field
Easily update the modem’s firmware in the field
Use a wide range of flexible remote control options
As shown in Figure 1-3, both modems accept Ethernet data to modulate an L-Band carrier. The demodulator receives and demodulates the L-Band carrier. Recovered data is then output on the Ethernet interface.
The Tx and Rx functions are independent with respect to modulation and coding. Both modems can operate in simplex (Tx only or Rx only) or duplex mode.

1.3.2.1 Operating Modes
Both modems support Uncoded, Viterbi, Viterbi+Reed Solomon, Sequential, TPC, and LDPC modes of operation. (STANAG 4486 (EBEM) in fall 2019)
1.3.2.2 Secure Management Interfaces
Chapter 6. MODEM CONFIGURATION
The modems support secure management interfaces, as part of its Management Security option. Detailed information about these configurations and modes, and their function al a ss oc iation with
the Modem, is provided in the following chapters in this manual.
1.3.2.3 Data Interfaces
The modems support only an Ethernet data interface in GigE Bridge mode.
1.3.2.3.1 10/100/1000BASE-T (Gigabit Ethernet)
Chapter 8. 10/100/1000BASE-T
The 10/100/1000BASE-T (Gigabit Ethernet, or GbE) interface performs a simple bridge function and passes IP packets, unaltered, in each direction between the Local Area Network (LAN) (10/100/1000BASE-T interface) and Wide Area Network (WAN) (modulator / demodulator).
IP packet traffic is framed via High-level Data Link Control (HDLC) encapsulation by the modem logic, and the modem is both the origination and termination point for HDLC encapsulation. HDLC CRC-16 verification is performed on all received (from WAN) HDLC frames.
(GbE) INTERFACE
1.3.2.4 Independent Tx and Rx Function
The Tx (modulator) and Rx (demodulator) sides of the modem are functionally independent and separately controllable. The baseband Tx and Rx sides of a communication channel passing through the modem are independently configurable, including the ability to select different parameters (to include data rate, coding, modulation, and spreading) in support of asymmetrical operation.
Introduction 1–7 MN-SLM-5650C
SLM-5650C / SLM-5650C-ODU Satellite Modem Revision 1
1.3.2.5 Verification
Both modems include test modes and loopbacks for rapid verification of the correct functioning of the modems. Of particular note is the IF loopback, which permits the user to perform a quick diagnostic test without having to disturb external cabling. During the loopback, the receive frequency configuration parameter is temporarily changed to match that of the Tx side, and an internal RF switch connects the modulator output to the demodulator input. When normal operation is again selected, all of the previous receive frequency is restored.
1.3.2.6 Updating Modem Firmware
Chapter 4. UPDATE FIRMWARE
Both modems store their firmware in flash memory, which allows the modems to upload firmware downloads from an external PC once Ethernet connectivity has been established. Firmware updates may be obtained free from CEFD via e-mail from CEFD Customer Support during normal business hours.
1.3.3 Interoperability
1.3.3.1 Legacy Modems
The modems are compatible and interoperable with all specified SLM-5650C modes of operation of the following legacy modems:
SLM-5650A
SLM-5650B
The remote control protocol is not backwards compatible.

For baseband data rates > 1544 kbps, the maximum initial acquisition time is 1.5 seconds.
Reacquisition
Reacquisition is achieved, as follows, after a period of up to 15 minutes of the absence of signal when the carrier returns to within 500 Hz of its original frequency.
For baseband data rates between 64 kbps and 128 kbps, the maximum reacquisition time shall be 45 seconds.
For baseband data rates between 128 kbps and 1544 kbps, the maximum reacquisition time shall be 20 seconds.
For baseband data rates greater than 1544 kbps, the maximum reacquisition time shall be 1 second.
System Retention
Synchronization and BCI are maintained for all Eb/No above the reference Eb/No (BPSK/QPSK/OQPSK/8PSK) for signal loss of up to 50 modulation symbol periods, with a probability of at least 90 percent.
Receive Timing Jitter
The Rx output clock peak timing jitter cannot exceed ± 5 percent at the reference Eb/No when the modulated signal meets the modulation timing jitter requirement.
