Embodiment

E1/V.35 Date Conversion Unit as shown in Figure 9 is by Main Processor Unit (see figure 1), power conversion unit (see figure 2), V.35 interface circuit unit (see figure 7), E1 interface circuit unit (see figure 4), led circuit indicating member (see figure 6), clock and reset circuit unit (see figure 8), webmaster control unit (see figure 3), DIP control unit (see figure 5).Wherein Main Processor Unit adopts two G.704 framing deframer structures, meets ITU-T G.703, G.704, G.706, standard G.803.Transparent or the framing mode of optional E1 interface, the non-CRC multi-frame of framing mode CRC/ mode adaptive.The E1 interface is optional PCM30/PCM31 structure under framed mode, but the time slot bandwidth of flexible configuration 64Kb/s is supported the setting that intercouples of two ends bandwidth.Built-in voltage controlled oscillator, following the tracks of V.35, interface regularly need not external voltage controlled oscillator.Support multiple circuit timing mode, built-in error code testing unit can cooperate multiple Loopback Mode to carry out the diagnosis and the test of circuit.Complete light is alarmed, and can show the warning information and the state of local and far-end, and V.35 interface can work in DTE or DCE pattern, input data and clock phase self adaptation.

The webmaster control unit can carry out software control to equipment, can carry out the parameter setting to bandwidth, timing mode etc.; Can know the operating state of the equipment of local and far-end.The DIP control unit can carry out hardware setting to time slot, loopback and test.For assurance equipment can be worked reliably, also adopt the power conversion unit of low pressure, low-power consumption at the power supply design aspect, cooperate anti-surge, overshoot unit that the Electro Magnetic Compatibility of equipment and reliability are further strengthened.

In sum my E1/V.35 of company Date Conversion Unit exploitation, purport is for our user provides convenience, stable and protocol conversion device reliably, has strengthened the flexibility of telecom operators' layouts.
