managed 16 E1 to 3 Gigabit Ethernet Converter with 2 SFP slot

Functions:
16E1-10/100/1000M Gigabit Ethernet interface converter used back multiplexing technology, transfer 10/100/1000M Ethernet data by using multi E1 channels. Realize convert between 1 to 16E1 channels and Ethernet interface. It can transmit signal of E1 channel to RJ45 interface point to point, realize the connection of E1 channel and Ethernet. also realize 10/100/1000M over 1000M fiber transmission and transmit 20/40/80/120km.this product has 3 electrical Ethernet port 10/100/1000M and 2 fiber SFP slot (comply with 1.25G SFP module),1 console port, SNMP/GUI support.

Ordering information:

Features:
l        Realizing the transparent transmission of Ethernet data via 1 to 16 E1 lines
l        Ethernet support the working mode : full duplex  and  half-duplex adapt
l        Support 10240 bytes MTU packet.
l        E1 interface in compliance with ITU-T G.703, G.704 and G.823
l        E1 Support 75Ω/unbalance impedance or 120Ω/balance for order
l        E1’s Support local and remote loops
l        Support 3 electrical Ethernet port 10/100/1000M (total bandwidth is 1000M) and Vlan division; support 2 fiber port SFP slot(for 1.25G fiber module) and1 console port
l        Support VLAN overlong data package transmission and can work with switch which support IEEE802.1Q
l        Support full indicators: Power status indicator, Status of activity (E1's),indicator LAN (Ethernet ports),optical connection indicator etc.
l        Support AC+DC power for redundant
l        Console port has below function:

Has OAM frame management;local device could read and manage remote device work status;
Can do VLAN division based on PORT for local device and it wouldn’t effect the 802.1 Q VLAN division for remote device,then local and remote can do same VLAN division;
Ethernet port can do priority set;
