I ntroduction

ntroduction

ntroduction :

MODEL7212 bridge provides easy conversion from ITU-T G.703

E1 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 E1 unframed

mode, including fractional E1 per request.

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 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

10/100BaseT(X) interface.
