Transparent transmission of E1 flows via packet networks based on the IVA Stag 24E multiplexer switch enables to build next-gen networks and to use existing equipment at new levels of quality and cost-effectiveness. Integrated full-function controllable Gigabit Ethernet 2+ level switch and two FOC interfaces (max. 120 km per fiber) provide wide-range application for this solution. Building small-scale multifunctional backhaul networks with transmission requirement of max. 24 E1 flows via data transmission network without communication quality loss. Integration of third-party equipment with similar interfaces into the infrastructure.

  • Support of dual-channel CSFP modules allows to connect max. 4 FOC lines via 2 SFP baskets
  • Low cost of equipment and its operation
  • Transmission of 24 structured/unstructured E1 flows via data transmission network without loss of communication quality
  • Local traffic mirroring
