Description:
This interface converter provides one unframed 2048K E1 interface and one Ethernet interface to achieve 10/100Base-T Ethernet data transmission on the E1 channel. It is a high performance, self-learning Ethernet bridge. This device is the extension device of Ethernet, using network (PDH/SDH/Microwave) that provide E1 channel to achieve local and remote Ethernet interconnecting with serial interfaces at a lower cost. The device has inter-set loop test function to facilitate the project launching and daily maintenance.
Features:
(1)Realize monitor of remote equipment from local equipment( Having two row of LEDs, upper row indicate local status, lower row indicate remote status, unframing equipment have no this function.)
(2)Based on self –copyright IC.
(3)Ethernet interface Semi/full duplex self adapt, support VLAN.
(4)Ethernet interface support auto-mdix.
(5)Provide 2 clock types: E1 master clock, E1 line clock.
(6)provide 3 loop functions: local loop, to remote loop, order remote loop.
(7)Have pseudo random code test function, easy the installation and maintenance.
(8)E1 can support rate N*64k(N=1-32)
(9)Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance.
(10)Have Ethernet monitor self-reset function, equipment will not dead.
(11)Provide detecting realtime Ethernet communication status.
(12)Network manager interface use SNMP.
(13)Two types:Standalone, desktop, 19inch;Card,usually be inserted in our rack 19 inch.
