Product function: TD CNV FEI/V35+ETH (providing conversion from El interface to Ethernet interface, V.35 interface)

Product introduction:

TD CNV FEl /V35+ETH uses El slot multiplexing technology to choose random slot from standard El channel for different interface, realizes data conversion from El interface to V35 and ETH interface and compose V35 channel of Nx64K(N=l -32). It is suitable for the case that part slot of El channel can be used. The interface mode of V35 data is DCE, which can be connected with DTE of DCE equipment; Ethernet interface 10/l00M, half/full duplex self-adaptable, and supports VLAN protocol;

Product characteristic:

 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);

 based on self-copyright IC;

 overall rate of V.35 and Ethernet is 2048K, Ethernet rate will be allocated automatically after V.35 rate is set;

 realizes automatic rate following of remote-end equipment ordered by local-end equipment; Ethernet port

 provides 4 clock types: El master clock, El line clock, V.35 master clock, V.35 external clock;

 provides 3 kinds of loop-return function, namely El self-looping at local end, V.35/Ethernet self-looping at local end, and V.35/Ethernet being ordered to self-loop at remote end;

 has the function (PATT) of pseudo-random code testing, convenient for opening of the circuit, and can be used as a 2M error code instrument;

 supports 750 unbalanced and 1200 balanced impedance at the same time;

 V.35 supports hot plugging and connection with DTE and DCE equipment;

 Ethernet interface 10/l00M, half/full duplex self adaptable, supporting VLAN and AUTO-M DIX (crossed line and straightly connected line self-adaptable);

 has self-reset function of Ethernet monitoring, equipment will not die;

 support SNMP management through our 19inch 4U chassis
