Naturally, the design provides for overvoltage protection in accordance with the requirements of the certificates of conformity, but situations are possible (for example, a lightning strike) when the protection may be ineffective. To facilitate the elimination of the consequences of such situations, it turns out to be advisable to use modules built on the mezzanine principle. This module has a main board on which all the most expensive components common to all channels are located - FPGA, processors, interface components, power supplies, etc. board by means of pin connectors. In the event of an abnormal situation, the damaged small mezzanine board, which has a very low cost, fails and is replaced. Each mezzanine card serves two digital telephones ; the module uses 12 such cards (24 channels). © Ramtronica 2012 home news About company For partners Vacancies Contacts The address: 107392 Moscow, st.
