P-195 switch is designed for organizing telephone communications in the field using analog telephones, as well as transferring voice information digitally over IP networks (IP-telephony) using SHDSL and Ethernet technologies (IP-organization of hybrid voice networks).

Basic technical properties:

  • modes of operation: manual switching (via operator) and automatic telephone exchange;
  • connections of the telephone in the central battery and local battery mode; provision of automated telephone communication for up to ten subscribers over two-wire field cable lines (P-274M type) via the FXS interface;
  • output of subscribers to external telephone networks through two FXO interfaces via two-wire field cable lines (P-274M type);
  • access to external communication networks via digital data SHDSL and Ethernet interfaces;
  • possibility of combining the same type of field telephone switches with a single numbering plan for the FXS/RXO interfaces, as well as the built-in SHDSL modem;
  • operation in the modem mode for data transmission in IP-networks (transparent Ethernet bridge);
  • made in an airtight impact-resistant casing made of aluminum alloy; round-the-clock mode of operation.
