  • two replaceable power supplies either –48V or ~220V

Main purpose of the IVA Stag STM multiplexer is to demultiplex E1 flows from the SDH flow of STM-1 and to transmit them via the packet Ethernet network. Multiplexer switch is able to build small-scale backhaul networks on its own basis due to the fully functional and controllable Gigabit Ethernet level 2+ switch and two FOC interfaces (max. 80 km via one channel). Broad functionality includes implementation of algorithms for prioritizing traffic to level 4, as well as combining bandwidth (100 Mb /s, 1 Gb/s, 10 Gb/s) in various combinations based on copper optical and wireless technologies.

  • Built-in full-functioning level 2 switch supporting all standards necessary for building up-to-date networks: traffic prioritization with 4 priority queues, VLAN
  • Flexible control and diagnostics. Support for SNMP, Web, Telnet, local management console, port mirroring, text configurations store and modify function
