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.
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 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.
