POTS and DSL phone line protection
Grounding reference POTS positive and negative connectors
This description includes three types of ground-referenced ordinary telephone (POTS) positive and negative connectors. Ground-referenced applications are often associated with the telephone switchboard. Most user terminal equipment (CPE) protection schemes are not ground referenced. POTS (plain old telephone service) lines carry normal telephone voice signals. When ringing, the voltage can reach 275 volts. These solutions can also be used in most ADSL applications (max. Frequency 1.1 Mhz).
Ruilon offers a range of SIDACtor®, TeleLink or PTC solutions. Listed on the left are several common solutions.
With PTC or LFR, devices suitable for this protection can be reduced to "B" devices. Many devices are available in DO-214 / Compak packages. With limited board space, the P6002CB is an excellent solution. In many ITU K.20 applications, "A" devices can be used.
