CLO-10 Link Optimizer Revision 1 Redundant System Operation MN/CLO-10.IOM
Figure A-8 shows the functional block diagram of Bridge Mode. In this example, Traffic Unit #2
is being bridged and, as the figure shows, the only energized “baseball” switches are on Traffic Unit #2.
A.4.2 Backup Mode Operation
Backup Mode is similar to Bridge Mode, with an added function: In Backup Mode, the Redundant Unit completely replaces the Traffic Unit. More specifically, the Redundant Unit will now be online, and the failed Traffic Unit will go offline. The output IF signal directed to the demodulator is subsequently taken from the Redundant Unit.
Figure A-9 shows the functional block diagram of Backup Mode. In this example, Traffic Unit #2
is being backed up and, as the figure shows, all of the “baseball” switches are energized on the IOSM on Traffic Unit #2.
Backup Mode can be done manually or automatically. In automatic mode, the Redundant Unit will monitor all of the Traffic Units continuously. When a fault is detected on any of these active Traffic Units, the Redundant Unit will first bridge the faulted unit, then back it up. When a faulted Traffic Unit needs to be replaced, its IOSM can be separated from the Traffic Unit chassis, leaving the active online Redundant Unit HSB Daisy Chain intact through the IOSM switch module. The chain can be extended without affecting the online unit’s operation.

A.5 Cables and Connections
Once the CLO-10s and the accompanying equipment have been mounted, the user must properly
attach all required cabling. Referring to Figure A-10 and Figure A-11, interconnection between
all equipment in the Daisy Chain Redundancy System is accomplished as follows:
• Connect Redundancy and Traffic Unit(s) using the High Speed Bus Cable, fabricated and
supplied by CEFD. This cable connects to the DB-25F J2 Redundancy connector on each unit, and consists of as few as (2X) DB-25M connectors (for the CEFD P/N
CA/RB0014-1-U2 1:1 Cable, shown in Figure A-10) to as many as (13X) connectors (for the CEFD P/N CA/RB0014-12-U2 1:12 Cable, shown in Figure A-11). There will be only as many DB-25M connectors as is required for the specific 1:N Redundancy system.
IMPORTANT
• Using CEFD-supplied BNC patch cable CA/BNC75OHM, first connect the inputs and
outputs between the Redundant Unit and Traffic Unit #1; then, connect the inputs and outputs between each Traffic Unit subsequent in the redundancy chain.
The unit’s assignment number must match that of the numbered DB-25 connector on the High Speed Bus cable (CEFD P/N CA/RB0014-XX-U2).
• For the interfaces between the CLO-10, modem, and the up and down converters, use
standard off-the-shelf 75Ω BNC male-to-BNC male patch cables, supplied by the user.
As an alternative to using off-the-shelf patch cables, the user may purchase IF Cable
PL/0813-4 (75Ω BNC male-to-BNC male, 4’) from Comtech EF Data; this cable can be
ordered at the same time the order is placed for the CLO-10 Daisy Chain Redundancy System.
A.5.1 75Ω Load in Redundant Unit
As shown in Figure A-10 and Figure A-11, a 75Ω load (CEFD P/N CN/CXLBNCTM01) must
be installed in the J5 (“To U/C”) port on the Redundant Unit’s IOM. This load is needed to terminate the splitter on the IOM.

1.1 Overview

The CLO-10 is Comtech EF Data’s Link Optimizer incorporating DoubleTalk™ Carrier-in-Carrier® technology. The CLO-10 allows transmit (Tx) and receive (Rx) carriers in a full-duplex link to use the same transponder segment via advanced signal processing techniques. The result is a reductio n in bandwidth required for the duplex link by as much as 50%.
The CLO-10 operates on the 70/140 MHz IF band, which facilitates retrofitting into existing systems. The unit is installed in the IF path between the modem and the up/down converters. The CLO-10 does not require prior knowledge of the signals to be processed (i.e., modulation type, FEC, etc) other than the bandwidth and center frequency of the desired signal.
Figure 1-1 shows the CLO-10 Link Optimizer. The Link Optimizer can be configured for two versions – the standard CLO-10-1 (shown), and the CLO-10-2, which features the optional redundancy hardware upgrade.

1.2 Features

The CLO-10 includes the following features:
• DoubleTalk™ Carrier-in-Carrier® allowing Tx and Rx carriers of a full-duplex link to use the same transponder segment
• 50- 90 and 100-180 MHz frequency range
• Signal Bandwidth up to 10MHz (bandwidth typically refers to usable bandwidth of signal
of interest)
• 10/100 BaseT Ethernet (Telnet), RS-232 or RS-485 for M&C remote control
• Fully Accessible System Topology (FAST)
• Optional User-configurable Redundancy — 1:1 up to 1:12 (CLO-10-2 unit only)
• Future / planned upgrade: HTTP, SNMP Remote Management

1.2.1 DoubleTalk™ Carrier-in-Carrier®

Designed for bandwidth compression, DoubleTalk™ Carrier-in-Carrier® (CnC) uses a patented technology that allows full duplex satellite links to transmit concurrently in the same segment of transponder bandwidth.
CnC is complementary to all advances in modem technology, including advanced FEC and modulations techniques. As these technologies approach theoretical limits of power and bandwidth efficiencies, CnC utilizes advanced signal processing techniques to achieve a new dimension in bandwidth efficiency.
CnC can be successfully deployed in bandwidth-limited as well as power-limited scenarios. Combining CnC with advanced FEC techniques such as Turbo Product Codes (TPC) or Low Density Parity Check Codes (LDPC) [also used by DVB-S2] can recover enough power that can then be traded for bandwidth.

1.2.2 Software – Flash U pgrading

The internal software is both powerful and flexible, permitting storage and retrieval of up to 10 different unit configurations. The CLO-10 uses ‘flash memory’ technology internally, and new firmware can be uploaded to the unit from an external PC. This simplifies software upgrading, and updates can now be sent via the Internet, e-mail, or on disk. The upgrade can be performed without opening the unit by simply connecting the modem to the Ethernet port of a computer.

1.2.3 Verification

The CLO-10 includes test modes for rapid verification of the correct functioning of the unit. Test modes that exercises various signal paths within the CLO-10, as well as carrier test modes, allow an operator to quickly perform simple diagnostics without having to remove/connect cables from the unit.

1.5.1 F A ST Sy stem

Comtech EF Data provides FAST (Fully Accessible System Topology) as an enhancement feature available in CEFD products, enabling on-location upgrade of the most operating feature sets - in the rack - without removing a unit from the setup.
When service requirements change, the operator can upgrade the topology of the product to meet those requirements within minutes after confirmation by Comtech EF Data. This accelerated upgrade can be accomplished only because of FAST’s extensive use of programmable devices incorporating Comtech EF Data-proprietary signal processing techniques. These techniques allow the use of a unique access code to enable configuration of the available hardware. The access code can be purchased at any time from Comtech EF Data. Once obtained, the access co de is loaded into the unit via the front panel user interface keypad or the rear remote port.
With the exclusive FAST technology, operators have maximum flexibility for enabling functions as they are required. FAST allows an operator to order a modem precisely tailored for the initial application.
1.5.1.1 FAST Options
FAST permits the purchase and installation of options through special authorization codes entered remotely, or via the front panel user interface keypad where immediate implementation of the different options is facilitated. All FAST options are available through the basic platform unit.
1.5.1.2 FA ST Implementation
FAST is factory-implemented in the modem at the time of order. Options for basic modems can be ordered and installed either at the factory or in the field. The operator can select Bandwidth options that can be activated easily in the field.
