OVERVIEW
Based on self-copyright IC.
Ethernet port 10/100M half/full duplex self adaptable,
supporting VLAN.
RJ45 interface supports AUTO-MDIX.
Provides 2 clock types: E1 master clock, E1 line clock.
Provide LAN auto reset function, run more stably.
Has the function of pseudo-random code testing, convenient for
opening of the circuit, and can be used as an error code
instrument.
Have three LoopBack Modes: E1 interface LoopBack (ANA) LAN
interface LoopBack (DIG) command the remote LAN interface
LoopBack (REM) 75-ohm dual coax and 120-ohm twisted-pair G.703
connections provided, only push the switch at the back panel of
the device to adjust it.
With abundant presentation function of Ethernet data, can detect
real-time data communication status.
Can realize SNMP management
