1 Surge protection for telecommunication lines

2 Surge protection for telecommunication lines Surges often enter structures via telephone and data lines, thus affecting the equipment. The same as power supply lines, they can cover large distances and connect very sensitive electronic equipment. Besides, telephone and data lines convey normally very low currents and reach the most fragile components. Examining any electronic device, it is clear that the power supply part is formed by more robust elements, while data communication lines connect directly to integrated circuits, other electronic components through the printed board thin tracks. Surges can cause severe damages in these tracks and components, degrading or destroying them and also affecting the data they store. Telephone and data lines are often ways where surges enter the structure, affecting the equipment. Telephone lines connect not only phone terminals but also more important and sensitive equipment, such as faxes and modems, inside and outside computers. Furthermore, one of the consequences of the global use of Internet is that many machines (PLCs, electrical house-hold, etc.) activate through the telephone line. Another very common trend is to design all kind of devices for remote distance controlling. This process often means the multiplication of cross-connections and wiring between devices that are placed in separated buildings or with different grounding. The risk of surges damaging the equipment increases then considerably, causing important economic losses not only due to the equipment damage but also the delay or cancellation of the processes and the services they should supply. Protecting communication lines against surges can solve all these problems. Aplicaciones Tecnológicas, S.A. supplies specific data and telephone SPDs for the most common working conditions. Besides, being manufacturers, we can develop new devices for the new telecommunication types that appear in the market. Our SPDs are usually made of screwed terminals instead of RJ11 ones because they withstand higher currents. Data and telephone lines need a wide previous study of the systems to be protected. Telecommunications is a field in constant evolution, where high precision is required and many different procedures exist. Each transmission protocol has its own working voltage, type of connection, pin-out, etc. All these data should be well known before designing a surge protection strategy that, firstly, does not affect the user and, secondly, is efficient against transient overvoltages. ATFONO Series For protection of standard, ADSL and ISDL telephone lines. ATLINE Series Data lines protection with a wide range of working voltages. ATLAN Series Computer lines and network protection (switches, hubs). ATFREQ Series Coaxial cable protectors for TV, CCTV and High Frequency signals.

3 AT91 Series - ATFONO Modular protector for telephone lines Efficient protection for analogical and ADSL telephone lines, containing coordinated protection for one pair of lines. Protection for telephone lines and also for the digital and analogical equipment connected to these lines (fax, modem, etc). Discharge takes place in an internal encapsulated element, with no external flash. Both common and differential modes of protection. Low residual voltage. Very fast response. Connection with screw pressure, which provides better lightning current withstanding capacity than usual telephone connectors. AT91 SERIES- ATFONO AT9101 ATFONO: prepared for telephone lines ATFONO SPD has been tested in official, independent laboratories, obtaining their characteristics according to relevant standards (related in the table). INSTALLATION ATFONO Surge Protective Devices are to be installed in series with the telephone line, at the point where the line enters the building and always complying the telephone company indications. When the devices to be protected are placed in different buildings and intercommunicated, SPDs should be placed both where the line goes into and out of the buildings. Output to the equipment Screen Input from the line The recommended procedure for its installation is the following: EARTH 1. Cut the telephone cable. 2. Insert the telephone ends in the connectors. Verify carefully that input and output connections are correctly placed. 3. If the cable is screened, connect the screen at the indicated place. 4. Connect the earth terminal to the earth termination system. Earth connection is a must. Earthing in all the installation must be bonded either directly or by a spark gap and resistance should be lower than 10Ω. If the indications of this datasheet are not fulfilled during the use or installation of the SPDs, the protection assured by this device could be endangered.

Each ATLINE can protect two of these wires. It is very important to know precisely the working voltage, current and function of each wire, in order to select the proper SPD. In case where two equipments located in separated buildings but linked together are to be protected, protection must be installed in both sides of the line.

16 ATFREQ Series Surge Protective Devices for Coaxial cables ATFREQ SERIES Wide range of protectors for different frequencies and connectors. Due to their placement, aerials are one of the most exposed elements to lightning discharges. Even when an external lightning protection system exists, the discharge secondary effects can affect the TV or RF signals. ATFREQ Surge Protective Devices protect the signal cable deriving the induced and conducted surges to the ground, thus avoiding damages to the communication and TV equipment and to the connected devices (DVD, video, decoders, home cinema sets, etc.) Optimum coupling with imperceptible losses. Small attenuation in the signal even for very high frequencies. Short response times. Discharge takes place in an internal encapsulated element, without external flashes. Small size. Specific connectors for each application. INSTALLATION ATFREQ SPDs are to be inserted in series with the aerial signal cable. It is convenient to install it as close as possible to the equipment to be protected. Each protector is provided with two coaxial connectors for an easy insertion and one earthing terminal. We supply SPDs provided with the most widely employed connectors (BNC, UHF, N, F) and male/female adaptors for direct insertion in any connection. It is important to point out that ATFREQ protects the signal coaxial cable coming from the aerial, not the power supply. Power supply should be protected using specific SPDs such as ATSUB, ATSHIELD, ATCOVER, ATSHOCK or ATVOLT. Connection to earth is carried out using a M5 screw placed at the SPD side. It must be as straight as possible, using a proper terminal and cable. EARTH Earth connection is a must. Earthing in all the installation must be bonded either directly or by a spark gap and resistance should be lower than 10Ω. If the indications of this datasheet are not fulfilled during the use or installation of the SPDs, the protection assured by this device could be endangered.
