Signaling acquisition device and method

Abstract

The invention relates to signaling acquisition device and method. The signaling acquisition device comprises an E1 / T1 interface module, a time slot interchange module and a data acquisition module, wherein the E1 / T1 interface module is used for realizing the code pattern conversion of an E1 / T1 signaling link to obtain a first serial signal, and transmitting the first serial signal to the time slotinterchange module; the time slot interchange module is used for copying the first serial signal to the data acquisition module, and exchanging and configuring a signaling time slot in the received first serial signal identified by the data acquisition module to obtain a second serial data, and sending the second serial signal to the data acquisition module; and the data acquisition module is used for identifying the signaling time slot in the first serial signal copied from the time slot interchange module, feeding the signaling time slot back to the time slot interchange module, and acquiring the data of the second serial signal exchanged and configured by the time slot interchange module. The invention can identify signaling time slots, automatically configure the signaling time slotsand carry out the data acquisition of the signaling time slots according to the identification result, thereby meeting the requirement on the automation and the intellectualization of signaling acquisition.

Description

technical field [0001] The invention relates to the communication field, in particular to a signaling collection device and method capable of automatically identifying signaling time slots. Background technique [0002] E1 / T1 is an interface widely used in the communication field. E1 is a European standard with a rate of 2.048Mbps; T1 is a North American standard with a rate of 1.544Mbps. Here we only take E1 as an example to illustrate. From the physical interface point of view, the E1 interface uses time division multiplexing to transmit data. Specifically, a frame is divided into 32 time slots, and each time slot is 8 bits. TS0 is a synchronous time slot, and TS1-TS31 are signaling or voice time slots; from the perspective of transmission channels, if one time slot is used as a channel, the transmission rate is 64Kbps; if several time slots are combined as a channel, the transmission rate is 64Kbps. The rate is Nx64Kbps; if a time slot is divided into multiple channels, ...

Problems solved by technology

[0005] Generally speaking, the traditional technology is realized by using time slot crossover convergence equipment and E1 acquisition equipment together. After many input E1s are converged by time slot crossover equipment, the signaling time slots are converged to a small number of output E1 ports, and then sent to The E1 collection equipment is used for collection. Here, it is necessary to manually configure the exchange configuration table to exchange and configure the signaling time slots, which increases the difficulty of the project and makes it difficult to ensure the accuracy. Moreover, since two devices are required to cooperate to realize the collection of signaling, it is not easy to reduce Cost; there is a problem of cooperation between multiple devices, which introduces more fault points; even if the time slot scanning is implemented in the time slot convergence device, the scanning result must be sent to the other party, and there is a problem of interaction between the two, which increases the difficulty of implementation and point of failure
