Abstract

A multiplex Ethernet-E1 bridge comprises a four-E1 channel transmitting/receiving module at an E1 interface end for transmitting/receiving the signal on the four E1 channels; a programmable logic module for dividing LAN data wave into multi-path data streams and dispatching to the four E1 channels, meanwhile converging the four E1 data streams into one data stream path and transmitting to an Ethernet transmitting/receiving module; a phase-locking module for realizing clock synchronization and phase locking; and an Ethernet transmitting/receiving module for transmitting and receiving data on the Ethernet. The utility model can realize transmission/reception of Ethernet data and E1 data, and mutual conversion of these two types of data.

Description

Multiple connection type Ethernet-E1 bridger

The utility model is transmitting-receiving and the two kinds of devices that data flow is changed mutually that are used for realizing Ethernet data and multi-channel E 1 data.

At present, existing same category of device is when realizing that Ethernet data and E1 channel data are transmitted mutually, because the 2.048Mbps transfer rate of E1 channel is much smaller than the 10Mbps transfer rate of Ethernet, thereby forms communication performance bottleneck.Such system will cause the congested of network under the applied environment that is similar to the expansion that utilizes the E1 channel to realize local area network (LAN).

The purpose of this utility model is: it utilizes programmed logical module, realizes multiple connection type Ethernet-E1 bridger that multichannel E1 channel data stream and ethernet data stream are changed mutually.

In order to achieve the above object, the technical solution of the utility model is: it comprises the E1 channel transceiver module that two-way is above, a slice programmed logical module, the phase-locked module of a slice, a slice Ethernet transceiver module; The receive clock line RXC1 of first via E1 channel transceiver module links to each other with programmed logical module through phase-locked module, the reception data wire RXD1 of first via E1 channel transceiver module, the reception data wire RXD2 that sends data wire TXD1, tranmitting data register line TXC1 and the second road E1 channel transceiver module, transmission data wire TXD2, tranmitting data register line TXC2 link to each other with programmed logical module respectively, and the control line of programmed logical module, receive clock line RXC, reception data wire RXD, tranmitting data register line TXC, transmission data wire TXD link to each other with the Ethernet transceiver module.

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, it comprises that E1 mouth interface end has four road E1 channel transceiver modules 1.1,1.2,1.3,1.4, the signal on the transmitting-receiving multichannel E1 channel, the circuit of each road signal transmitting and receiving module 1.1,1.2,1.3,1.4 such as Fig. 2, Fig. 3, Fig. 4, shown in Figure 5; A slice programmed logical module 2 with lan traffic demultiplexing data flow, and to four road E1 channel distribution, accumulates four road E1 data flow one circuit-switched data stream simultaneously, is sent to Ethernet transceiver module 4, and its circuit as shown in Figure 6; The phase-locked module 3 of a slice realizes clock synchronization and phase locking, and its circuit as shown in Figure 7; A slice Ethernet transceiver module 4, the data on the transmitting-receiving Ethernet, its circuit is as shown in Figure 8.

Channel transceiver module of the present utility model is the E1 module; Programmed logical module 2 be CPLD or FPGA or; Phase-locked module 3 is that second order is phase-locked; Ethernet transceiver module 4 is for meeting 802.3 protocol number standards.

Its signal process is: Ethernet transceiver module 4 (U2) receiving data stream from the Ethernet, and clock and data sent into programmed logical module 2 (U10), ethernet clock and data flow are converted to four road E1 clock and data flow, in this transfer process, will realize the distribution of data flow, bit synchronization and word synchronizing process, and be sent to four road E1 transceiving chips 1.1 respectively through data wire and clock line, 1.2,1.3,1.4 (U5, U6, U7, U8) data flow on the E1 channel of transmitting-receiving road, and data and clock are sent to programmed logical module 2 (U10) programmed logical module 2 (U10) four road E1 mouth data flow are synthesized one road ethernet data stream, and utilize phase-locked module 3 to be sent to Ethernet transceiver module 4 (U2).

The utility model has the advantages that: combine based on existing module and components and parts, can realize the ether netting index According to the transmitting-receiving of E1 data and the mutual conversion of two kinds of data flow.
