Framed E1 to 2*Ethernet+RS232 Multiplexer
GENERAL INFORMATION：
FE1/2*ETH+RS232 multiplexer provides conversion between ITU-T G.703 standard E1 interface and 2*Ethernet interface as well as 1 RS232 data channel which can be transmitted to exchanger, hub, router,...
PRODUCT CHARACTER:
(1) realizes long-distance monitoring of this end equipment to the far-end equipment (two-row indicating lamp, upper row indicating local status, lower row indicating far-end status)(suitable for framing equipment);
(2) based on self-copyright IC;
(3) Ethernet interface 10/100M, half/full duplex self adaptable, supporting VLAN;
(4)Ethernet port supports AUTO-MDIX (crossed line and straightly connected line self-adaptable);
(5) provides 2 clock types: E1 master clock, E1 line clock;
(6) provides 3 kinds of loop-return function, namely E1 self-looping at local end, Ethernet self-looping at local end, and Ethernet being ordered to self-loop at remote end;
(7) has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument;
(8) supports 75¦¸ unbalanced and 120¦¸ balanced impedance at the same time;
(9) realizes random choice of 31 time slots with hardware;
(10) E1 supports rate of N*64k (N=1-32), which can be regulated from 64K to 2048K;
(11) has self-reset function of Ethernet monitoring, equipment will not die;
(12) with abundant presentation function of Ethernet data, can detect real-time data communication status;
(13) supports super terminal control device with Console port;
(14) RS232 channel can transfer asynchronous serial data with self-adaptable baud rate of 300 to 19200;
(15) RS232 can transfer Console data of remote-end equipment such as Router;
(16)Two types:Standalone, desktop, 19inch;Card,usually be inserted in our rack 19 inch.
