Detailed Product Description

MODEL7212 converter provides easy conversion from ITU-T G.703 E1 fractional channel
to Ethernet interface. Can used widely in connecting between WAN and LAN, monitoring,
etc. The Ethernet interface is 10/100Mbps auto negotiation and can be full/half duplex.
The E1 is transparent and in full rate, which can support the A pair of MODEL7212
offer a cost effective solution for using existing E1 leased lines for
transparent Ethernet service. Local management of the MODEL7212 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. MODEL7212 compact G.703 Access Converter
provides fractional E1/2.048 Mbps Network Termination as well as serial or
Ethernet LAN interface conversion in a standalone or rack mount package.
MODEL7212 terminates the G.703 Telco interface and converts the data for transmission
to a user-oriented 10/100M Base-T interface
