4E1 to Ethernet 10/100Base-T Protocol/Interface Converter is designed to provides easy conversion from 1 to 4 E1 channels to Ethernet interface.
According with IEEE 802.3, support 10Base-T, 100Base-T
Support flexible setting of 1 to 4 E1 channels, auto detect the number of E1 channels and time-delay, select available E1 channels and more;
Provide 2 loop functions: local E1 loop, remote E1 loop.
Ethernet transmission transparent,support AUTO-MDIX, straight and crossover auto-adapt.
Can transmit super-long frame of IEEE 802.1Q, support Ethernet exchanger with VLAN function.
Support E1 channel hot plug, and auto detect available E1 channels.
Support reset remote system from local system.
4 E1 can have 10 ms time-delay, CRC alarm limitation can auto insulate bad-quality transmit channel by configuration, and is single direction insulation. when one direction error rate over limitation, cut only this direction, the other direction not affected.
Power supply option: AC220V, DC-48V. The positive and negative terminal can be exchanged for DC-48V, easy for installation and maintenance.
