SAFN is a flexible transport/access system specifically designed for private networks, with the aim of realizing networks integrating access and transport for data, voice and video transmission. It is a very reliable system, offering several advantages:

  • device connecting users to the carrier, with integrated access and transport functions to reduce costs and plants complexity (wiring, spare parts, maintenance)
  • flexibility of use both on Circuit Switching Networks (CSN) and Packet Switching Networks (PSN), guaranteeing the return on investment in the migration between networks
  • modular architecture meeting diversified –low / medium / huge- traffic requirements
  • typical device functionalities, such as VoIP Gateway and IP-PBX, to carry out service telephone systems, teleprotection functions towards distance protections
  • typical devices interfaces, such as digital I/O, interfaces towards protection and teleprotection equipment, specific interfaces for railway telephony
  • easy reconfiguration in case of bandwidth increase
