    Product Description
      8E1 (75/120 ohm) The optical Ethernet interface converter uses reverse multiplexing technology to bundle multiple E1 circuits for transmitting Ethernet data of 3-way Ethernet and 1-channel 100BASE-FX. 1-8 E1 channel to Ethernet interface between the conversion, to achieve E1 channel and Ethernet interconnection. The Ethernet package is available in GFP and supports LCAS and LAPS.
      The device supports flexible configuration of 1 to 8 E1 (75/120 ohms) channels, automatically detects the number of E1 and selects the available E1, and allows a certain transmission delay between the E1 circuits. Single line rate is 1984Kbit / s, 8-way bandwidth of up to 15872Kbit / s.
    Functional Properties
    ◆  Based on independent intellectual property rights of integrated circuits;
    ◆  To achieve the Ethernet data in 1 to 8 E1  in the transparent transmission;
    ◆  Can achieve the local, remote device reset operation;
    ◆  4-way E1 line, any two between the maximum delay difference of up to 220ms; when the delay difference is over, will have a delay difference overrun alarm, while business interruption;
    ◆  Ethernet interface 100BASE-FX, support VLAN protocol;
    ◆  Built-in dynamic Ethernet MAC address list (4096), with local data frame filtering;
    ◆  Single E1 line rate is 1984Kbit / s, 8-way bandwidth of up to 15872Kbit / s.
    ◆  Optional local timing and tracking E1 line timing mode, E1 line timing source can automatically switch according to the signal quality. Such as the system E1 line timing source for the first E1;
    ◆  Compliant with ITU-T standard protocol, GFP-F package recommendations G.7041, VCAT virtual concatenation and LCAS link capacity adjustment method Recommendation G.7042, Ethernet to nxE1 mapping recommendations G.7043, Ethernet to single E1 mapping Recommendation G.8040 ;
    ◆  E1 interface conforms to ITU-T G.703, G.704 and G.823, does not support the use of signaling time slots;
    ◆  E1 interface module contains built-in clock recovery circuit and HDB3 codec circuit;
    ◆  Equipment work to support the E1 channel hot swap, and automatically detect the effective E1 channel, the middle will not interrupt the data transmission;
    ◆  Support 1 to 4 E1 flexible configuration, automatically reset the number of E1 and delay and select the available E1;
    ◆  Can be composed of Ethernet E1 bridge (A) --- optical Ethernet E1 bridge (B) --- Ethernet fiber optic transceivers (C) topology, can be managed in the A side to the B and C points;
