  • metal case 10"
  • 4 x E1 interface
  • 2 x Gigabit Ethernet interface
  • 2 x SFP/CSFP 1Gb interface
  • Power ~220 V and –48В

Designed for combined transmission of structured and unstructured E1 flows (G.703, G.704) and Ethernet packets via packet data network using TDMoP, SAToP and CESoPSN technologies. Useful in building full-fledged multifunctional data and E1 flows transmission networks. Controllable L2+ switch enables to use IVA Stag 4E to build reliable and cost-effective data and E1 flows transmission networks without using third-party equipment. Simple integration into the existing network infrastructure including complex backup topology enables to upgrade the existing equipment in a short time – a strategically advantageous enhancement of service capabilities

  • CSFP module support
  • Max. 4 of E1 flows (structured / unstructured) with no quality loss
  • Local traffic mirroring
  • Frequency recovery algorithms that ensure stable operation at real networks
