E1 - 4 x ETH interface convertor, 75/120 ohm for E1 port , DC-48V

AN-E1-4ETH /DC/24

E1 - 4 x ETH interface convertor, 75/120 ohm for E1 port, DC+24V


AN-E1-4ETH converter provides easy and cost effective conversion from ITU-T G.703 E1 channel to 4 x Ethernet interfaces.

The 4 x Ethernet interfaces is 10/100Mbps auto negotiation and can be full/half duplex.

AN-E1-4ETH can be used in applications where several Ethernet ports are necessary and additional switch or hub installion is not possible. The E1 is transparent and in full rate, which can support the E1 unframed mode, including fractional E1 per request. A pair of AN-E1-4ETH offer a cost effective solution for using existing E1 leased lines for transparent Ethernet service. Local management of the AN-E1-4ETH Converter is provided via DIP switches.

Front panel LEDs monitor the G.703 link, Ethernet LAN and serial ports for status and Loss of Sync. AN-E1-4ETH compact G.703 Access Converter provides E1/2.048 Mbps Network Termination as well as serial or Ethernet LAN interface conversion in a standalone or rack mount package. AN-E1-4ETH terminates the G.703 Telco interface and converts the data for transmission to a user-oriented 10/100 BaseT interface.
