22 Testimonials The testimonials below reflect a choice of statements from our customers who have decided to write to us about their experience with DEV RF product solutions. These are honest and largely unedited comments and come from all over the world. Ericsson Television Limited, England At Ericsson Television we particularly like the DEV 1951 switch because it is perfectly suited for broadcast needs. Its output signal will persist even if power is lost to the unit. This is essential for the broadcast environment. It also offers the capability of hosting many different card types to suit different signal types, and can accommodate up to two switches in one chassis. DEV s engineers are capable of taking account of customer needs and making changes wherever appropriate. Steven Woodhead, Systems Engineering Group Manager, Ericsson Television Limited I.S.P.A.-SAT, Russia Top quality of DEV products, short delivery time together with professional approach allow us to implement our projects on the highest level and just in time. This is a result of professional work of all DEV team which is always a pleasure to deal with. Ivan Drozdov, Head of Branding and Marketing Department, I.S.P.A.-SAT BilgiPark TV, Turkey We actually thought our instruments were defective or needed re-calibration because the signals received were so strong and clean. But it turned out that the cause of this was simply the excellent transmission characteristics of DEV s systems. Nuriye Gungor, Project Manager, BilgiPark MDS America Inc., Stuart, USA We enjoy cooperating with the DEV Team so much because they find solutions for such a wide range of signal transmission tasks. Their order processing system is also very effective and they have always met their promised lead times. Allen Quinn, Sales and Marketing Manager Naxoo, Geneva, Switzerland Our satellite streams are analogue until they reach the cable head-end, where they need to be converted for digital transmission over the cable network. DEV solved this problem for us - and with much smaller devices than we used previously. That s why we chose DEV for the entire antenna-to-receiver transmission path.

23 DEV Glossary Term Explanation A 1+1 Redundancy In 1+1 Redundancy Schemes either a module or a complete path e.g. for optical signal transmission is built redundant. The main as well as the backup module/path is monitored in hot-standby. The switch over to the backup module/path can be done automatically based on different criteria s e.g. RF-Sensing. 3G-SDI 3G Serial Digital Interface (SDI) is defined by SMPTE (The Society of Motion Picture and Television Engineers) and consists of a single Gbit/s serial link for uncompressed signals, standardized in SMPTE 424M. 3-Gbps (3G) enables higher resolution of picture quality required in applications as digital cinema or HDTV 1080p. A/B-Alarm Indication of the power supply status via dry-contacts. B-Alarm means one power supply is faulty (non-critical because of the implemented power supply redundancy in all DEV equipment). A-Alarm is the higher rated alarm indicating that two power supplies are faulty. A/B Switch Switch to provide switching from signal source A or signal source B or vice versa. The switching can be done manually or automatically based on RF-Sensing, Dig-In or TRAC or remote controlled by SNMP. Active Combiner Active DEV Combiners are capable to combine up to 32 signals without loss. Active Splitter Active DEV Splitters are capable to split an input up to 128 outputs without loss or additional gain. Accumulated Accumulated Signal Power or Aggregated Power or Sum Signal Power Level is the integrated power of a bandwidth. AGC Automatic Gain Control (AGC), automatic adjustment of gain to achieve a stable output signal level. Alarm Connector Dry contact connector providing information about the status of either modules or a device. APC APC (Automatic output power control) used in optical amplifiers (EDFA) to ensure constant output power automatically. 23

24 DEV Glossary 24 Term A Amplitude Frequency Response ASI Attenuation Auto Mode Automatic Antenna Redundancy System Automatic Switch Back B Back Channel Network BER Bias Current Monitoring Explanation Amplitude Frequency Response is the indication of gain or loss characteristics over frequency in decibel (db). ASI is a serial video communications standard defined by the DVB consortium for use in transporting MPEG-2 encoded video streams. The standard is most commonly used to transports MPEG-2 streams. Data is transported at a rate of 270 Mb/s. A complete discussion of DVB-ASI specifications is provided in EN : Cabled Distribution Systems for Television, Sound and Interactive Multimedia Signals, available from ETSI. Attenuation describes the ratio between output and input level in decibel (db). In Auto Mode DEV devices e.g. redundancy switches can work fully autonomously without the need of a M&C-System. In a N+1 antenna configuration if the feed from a fixed antenna (N) fails, the DEV 1993 with option 30 will steer a motorised antenna (+1) to the appropriate satellite. After checking that the signals are within specification the signals from the motorised antenna will be switched to temporarily replace the fixed antenna. In case of redundancy switching a device equipped with the Option Automatic Switch Back is able to switch back from backup to main port after the status of main recovers. Back Channel Network is the 2-way communications link in cable networks. The enduser is able to send information, requests and/or demands back to the cable network operator. Bit Error Rate or Bit Error Ratio (BER) is the number of bit errors divided by the total number of transferred bits during a certain time interval. With the bias monitoring functionality, the LNB bias current of each channel is monitored within a user adjustable threshold window.

25 DEV Glossary Term B Bias Tee Bidirectional Switch Blocking Matrix BNC-Connector Broadband BUC C Carrier Detect Carrier to Noise Ratio (CNR) CATV-Band C-Band Explanation Bias Tee or LNB Powering provides power to operate a LNB. A switch that can pass signals in both forward and reverse directions. A blocking matrix is built with switches on both the inputs and the outputs. Each input signal can be switched to only one output port at a time. The BNC connector (Bayonet Neill Concelman) is a miniature quick connect disconnect RF connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is achieved with only a quarter turn of the coupling. Available in 50 or 75 Ohm versions to 4GHz. The term broadband refers to the wide bandwidth characteristics for signal transmission. Block up converter (BUC) converts a band of frequencies from a lower to a higher frequency. Carrier detect is the equivalent to RF Sensing but for video signals. It is used as a quality indicator to either just send an alarm to a M&C System or for instance to perform a redundancy switching fully autonomously. The carrier-to-noise ratio (CNR) or C/N is defined as the ratio of the received modulated carrier signal power C to the received noise power N. CATV (Community Antenna TeleVision) is the historic name for the frequency band from MHz (previously MHz) incorporating the remaining analogue terrestrial TV, Cable TV and modulator IF frequencies. C-Band designated for Satellite use is the band of frequencies from 3.7 to 4.2 GHz for downlinks, and the band of frequencies from GHz to GHz for uplinks. Polarisation can be Linear Vertical or Horizontal or Circular Left or Right handed. 25

26 DEV Glossary Term C CFP CWDM D Damage Level Data Backup db dbc dbm DC Blocked DC Supply Voltage DC -48 Volts De-/Multiplexer Explanation Core Function Products (CFP) are streamlined to core functions, offering cost-savings while providing high quality in RF signal transmission. Coarse Wavelength Division Multiplexing (CWDM) combines multiple wavelengths, up to 16, (multiple signals) on a single fiber optic cable. The Damage Level is the maximum input level at which the respective device takes damage. Data Backup is part of the DEV Web Interface, that makes it possible to save and restore device or instrument data as well as error log information of DEV devices. The stored data can be accessed on the device itself (SD- Card) and can be exported to a connected PC. db is a logarithmic unit used to describe a ratio of power. dbc - relative to the carrier - is the power ratio of the carrier level to noise level, expressed in decibels. dbm (sometimes dbmw) is an abbreviation for the power ratio in decibels (db) of the measured power referenced to one milliwatt (mw). In- or outputs which are DC blocked prevent the flow of DC voltage while passing RF frequency. DC supply voltage is available as an Option for all DEV devices providing DC power supplies instead of the standard AC power supplies. In Telecom installations a DC -48 Volt power supply is used. This is normally a battery based system that is continuously float charged. This allows for continued provision of telecom circuits even when AC power is out during storms etc. Bidirectional RF switch that can select one of many ports to a single common port or a single port to one of many ports. 26

27 DEV Glossary Term D Explanation Desktop Modules The DEV Desktop Modules belong to the OPTRIBUTION series and are standalone modules for optical transmission.

Commonly used when no M&C system is available or practical. In the case of modulator redundancy the Dig-in monitors the logic levels on the equipments alarm or fail relays. A diplexer is a passive device that implements frequency domain multiplexing. Two ports (e.g., L and H) are multipllexed onto a third port (e.g., S). The signals on ports L and H occupy disjoint frequency bands. Consequently, the signals on L and H can coexist on port S without interfering with each other. A Distributing Matrix allows to connect one input to multiple outputs simultaneously. Distribution Amplifiers are capable to split an input up to 128 outputs without loss or additional gain, typically offering additional features like LNB powering, tilt adjustment etc. Double pole, double throw (DPDT) consists to two switches (SPST - single pole, single throw) controlled by a single mechanism, sometimes named as Transfer Switch. Double pole, single throw (DPST) is a simple changeover switch providing two in / outputs switchable to a common port. Relay contacts, either generally open or generally closed, connected hardwired to a M&C System providing the status of dedicated features or common device status. Dense Wavelength Division Multiplexing (DWDM) combines multiple wavelengths, up to 80, (multiple signals) on a single fiber optic cable. 27

Insertion Loss (db) is defined as the drop in signal power. In case of insertion loss the input signal will be attenuated. Consequently the output signal amplitude is lower than the one of the incoming signal. Intermodulation Distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies in a system with non-linearities. The intermodulation between each frequency component will form additional unwanted signals. The Second Order Intercept Point (IP2) is a measure of linearity that quantifies the second-order distortion generated by nonlinear systems and devices. The Third Order Intercept Point (IP3) is a measure of linearity that quantifies the third- order distortion generated by nonlinear systems and devices. The required polarization can be selected using the bias voltage generated in the IRD 13 Volts = Vertical and 18 Volts = Horizontal. To select the required band the 22 KHz tone can control the switching. Low = Tone off or High = Tone On. The DEV IRD controlled switch uses the Volts and tone signals to route the required signal to each IRD automatically. IRD s can be installed in groups of 16, 32, 48 or 64.

A Monitoring & Control System is an almost software-based system providing monitoring and control ability of vendor independent equipment e.g. in head end stations. Other than traditionally it is the case for redundancy switches were In A is dedicated being the main input and In B the backup input, the functionality Main/Backup Swap changes dynamically the role of main and backup channel. After redundancy switching from input A to input B, B gets the role of the main input while A is the backup input and vice versa. Managed L-Band Distribution stands for a chassis which contains multiple L-Band distribution amplifiers of various fixed splitting ratios or switching scenarios e.g. matrix switch or RF matrix. As a standard all distribution amplifiers use RF-Sensing technology to check the signal performance, provide LNB power with current monitoring to alarm in case of a LNB failure and optionally provide a manual gain and tilt control function. In- and output connectors can be selected in 50 Ohm SMA (f) or 75 Ohm high precision F (f).

33 DEV Glossary Term M Matrix Switch MER MGC Monitoring Port N Explanation Matrix Switches are IRD controlled switches providing 4 inputs and up to 64 outputs. Each IRD connected to an output can choose the appropriate input. See also IRD Controlled Switch. The modulation error ratio (MER) is a measure used to quantify the performance of a digital radio transmitter or receiver in a communication system using digital modulation. MGC (Manual Gain Control) is used to manually adjust the gain. A Monitoring Port is an additional RF port providing the same or less signal level as e.g. at the appropriated in- or output. N+1 Redundancy N+1 redundancy ensures system availability in the event of a failure in one of the main paths. N main paths have at least one backup path (+1). N-Connector Noise factor Nominal Input Level Non-Blocking Matrix Named after Paul Neill of Bell Labs after being developed in the 1940 s, the Type N offered the first true microwave performance. The Type N connector was developed to satisfy the need for a durable, weatherproof, medium-size RF connector with consistent performance through 11 GHz. The noise factor is defined as the ratio of the output noise power of a device to the portion thereof attributable to thermal noise in the input termination at standard noise temperature T0 (usually 290 K). The noise factor is thus the ratio of actual output noise to that which would remain if the device itself did not introduce noise, or the ratio of input SNR to output SNR. A nominal signal level at the input is the recommended accumulated level to ensure the best performance. It is expressed in decibels. A non-blocking cross-point matrix is designed to allow one input or output to be connected to multiple inputs or outputs simultaneously. 33

R Redundancy Switch Redundant Amplifier Remote Control Switch for providing redundancy switching for example: 1+1 switching from main to backup device. N+1 switching from many main to a single backup device. N+M switching from many main to multiple backup devices. The Redundant Amplifiers ensure continuous operation in RF transmission applications to avoid signal loss if one amplifier fails. It is the consequent approach for no single point of failure having all active RF or digital componets redundant on a module basis. A remote control is a functionality which allows the user to interact between the devices without touching them. This can be done via a remote protocol e.g. SNMP or Leitch. 35

36 DEV Glossary Term R Remote Mode Return Loss Return Path Network RGC RF over Fiber RF Sensing RF Signal Recording RF Switch RF Threshold S SC/APC Seamless Switch Explanation Remote Mode is an operation mode which is controlled remotely i.e. from another place possibly far away from the system which is operated. This can be done via a remote protocol e.g. SNMP or Leitch. Return Loss (db) is defined as a ratio of the incoming signal to the same reflected signal at a discontinuity. See Back Channel Network. RGC (Redundancy Path Gain Compensation) automatically aligns the gain of the redundant link with the related main link in case of redundancy switching. RF over Fiber solutions convert analog RF signals into optical which are then transmitted over optical fibers and converted back to RF at various frequency bands. RF Sensing measures the accumulated RF power over the entire bandwidth. This value is a quality indication to either just send an alarm to a M&C System or to perform a redundancy switching fully autonomously. RF Signal Recording is able to record the results of RF Sensing and LNB Bias Current Monitoring in user-defined time intervals.
