16*E1 to 3x1000Base-TX+2x1000Base-X Interface Converter JHA-CE16G3F2

    • Transparent transmission of Ethernet data in 1 to 16 E1 circuits;
    • Can be equipped with five Ethernet switching electrical interface for the user to save an Ethernet switch;
    • 1000Base-TX Support 10/100/1000M, full/half duplex fully adaptive, support VLAN protocol;
    • Each port supports Ethernet support AUTO-MDIX (crossover cable and straight-line adaptation);
    • 16-channel E1 lines, the maximum delay difference between any two can reach 220ms; when the delay difference over 220ms, the delay will produce poor overrun alarm, while business interruption;
    • Built dynamic Ethernet MAC address list (4096), with local data frame filtering function;
    • E1 interface complies with ITU-T G.703, G.704 and G.823, do not support the use of signaling slots;
    • Timer mode, the optional local timing and tracking E1 line timing, E1 line timing source can be automatically switched according to the signal quality. Such as E1 line timing source system for the first Road E1, when the first E1 failure (serious warning
    • Compliance with ITU-T standard protocol, GFP-F encapsulation suggestion G.7041, VCAT virtual concatenation and LCAS Link Capacity Adjustment recommendation G.7042, Ethernet mapping to nxE1 recommendation G.7043, Ethernet to single E1 map suggestion G. 804
    • When transmission bandwidth increases, will not damage the Ethernet data; transmission bandwidth is artificially reduced, it can also be realized without damaging the Ethernet data network;

Ethernet to E1 Converter

  • 16*E1 to 3x1000Base-TX+2x1000Base-X JHA-CE16G3F2

    Interface Converter 


    The device using reverse direction multiplexing technology to bundle for multiple E1 to transmit the Ethernet data of 3Channel 1000BASE-TX and 2x1000Base-X. It can realize 1~16 E1 convert between Ethernet optical interface, to make E1 channels interconnected with Ethernet optical interface. Using GFP encapsulation, support the LCAS (link capacity adjustment scheme) and LAPS protocol. this device can support 1-16Channel E1 channel configuration, can automatically detect the number of E1 and select the E1 available. It allows E1 lines transmission time, single line rate is 1984Kbit/s, 4channe Ethernet bandwidth is 7936Kbit/s, 8channel bandwidth is 15872 Kbit/s, 16channel bandwidth can attain 31744Kbit/s.
         The device provides alarm function. The work is reliable, stable, and low power consumption, high integration, small size. Support SNMP Network management.

    • E1 tributary Ø ends may not correspond by serial connection;
    • When a single slip direction E1 fails, the other direction can still work;
    • E1 signal loop back and cut off the automatic detection function: When detecting the occurrence of a road E1 signal loop, the system cut off this E1; loopback released, E1 automatic recovery use this road;
    • Complete alarm indication, choose to display local / remote alarm;
    • Supports remote E1 line side loopback function to facilitate the testing of E1 lines;
    • Support local system for the remote system reset;
    • provide remote interface loopback command, easy to line maintenance;
    • Console management interface provides for easy installation opening;
    • Configuration network management module, support independent SNMP network management;
    • with this end in view the working status of remote device display function;
    • Multiple power mode options: AC220V, DC-48V / DC24V and the like;
    • DC-48V / DC24V power supply with automatic polarity detection function, when installed without distinction between positive and negative.
