EOC(Ethernet Bridge Over Coax) DT2112

Detailed Product Description

  EOC(Ethernet Bridge Over Coax)

DESCRIPTION

The EOC Ethernet Multi-tap (DT2112) combines Ethernet and CATV signals for transport over coaxial cables. It is a combination of a normal RF multi-tap with an Ethernet switch.DT2112 enables transparent layer 2 Ethernet connection over coaxial cable by combining an 1-to-12 RF splitter with a 2+12 port Ethernet switch and RF circuits for combining these two.

Data rate per port can be limited between 64 Kbps and 8 Mbps. When more than the programmed rate is sent or received through a port, packets are dropped. Port-based VLAN tags can be used to provide customer isolation. Traffic from cascade or subscriber port will only be switched to the trunk port to prevent pier-to-pier communication.

FEATURES

12 taps for coax to customers with RF and baseband Ethernet

Intelligent Ethernet switch

All ports can be disabled individually

Multicast and IGMPv2 snooping support

Automatic MAC address learning and ageing

802.1Q tagged based VLAN support
