Typical Installation



The O-9310 can multiplex up to 4 T1 or E1 signals for transmission over an optical fiber, resulting in longer reach without repeaters and superior performance compared to copper media.

The O-9310 also supports an optional 10 /100 BaseT ethernet bridge port, an optional V.35, X.21, RS449/V.36, RS232/V.28 or EIA530 or EIA530(A) with DTE/DCE selection.

Available in a cost-effective non-CPU model with DIP switch setup or an intelligent model with SNMP and remote configuration capability. Basic non-manageable model without CPU provides system setup and loopback by DIP switches setting. Application for the Optical T1/E1 extender include fiber connected extensions for LAN, WAN, SONET/SDH, ATM and DLC.
