1011-IP6820 Self-Healing Ring NTU
Or call us on

The Loop-IP6820 is a gigabit Ethernet self-healing ring network termination unit (NTU). A important protocol supported is G.8032 Ethernet Ring Protection on its WAN ports. For ring topologies the IP6820 supports auto-discovery to discover all units on the ring (a maximum of 128) as well as remote configuration for easy installation

All end equipment can be in packet format via Ethernet ports or serial data via RS232/422/485 interfaces, which are converted into packets within the IP6820. The device has two WAN optical interfaces, two LAN optical interfaces, four electrical LAN interfaces, and one alarm relay interface. Manufacturing options include four additional electrical LAN interfaces, four or eight RS232/422/485 interfaces, and two sets of Dry Contact in/out interfaces.
With an embedded GbE L2 switch chip, the IP6820 also supports RSTP and MSTP for all Ethernet ports. It can be powered by AC, single DC, or dual DC power depending on field requirements. PoE (Power over Ethernet) is available as a manufacturing option. Physical DIN rail mounting is also supported.

Applications for the IP6820 include automation, SCADA, surveillance, traffic control, transportation, and IP networking. Network topologies include ring protection, point-to-point, and point-to-multipoint. Easy installation and configuration make maintenance and expansion simple.
