Embodiment Construction

[0020] Functional Overview

[0021] Aiming at the problems in the prior art that the data recovery is not flexible enough to achieve data recovery by flipping all the bits of the encoded data, resulting in low efficiency and a certain delay in system data transmission, in the technical solution provided by the embodiment of the present invention , by setting the flip mask in advance, and flipping the predetermined bits of the coded data of each time slot according to the flip mask, since there is a one-to-one correspondence between the A-rate coding and the μ-rate coding of 8-bit speech coding, so by setting A specific inversion mask realizes the inversion of a specific bit, and can realize conversion between A-rate encoding and μ-rate encoding. If not specified, the encoded data mentioned below is the AMI-encoded data, occupying 8 bits, of course, the present invention is not limited thereto.

[0022] The present invention will be described in detail below with reference to...

Abstract

The invention provides a data transmission method based on AMI coding and a data processing device. The method comprises the following steps: flip data are preset and comprise a flip mask for indicating the flipping of a predetermined bit of the coding data, wherein, the coding data is subject to the AMI coding; a receiving terminal receives the flipped data from a sending terminal, and the flipped data is the coded data flipped by the flip mask; and the receiving terminal flips the flipped data according to the flip mask to obtain the coded data. The method and the device can achieve the data recovery smartly with high efficiency and reduce time delay during the system data transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an AMI code-based data transmission method and a data processing device. Background technique [0002] Digital network T1 (US standard, bandwidth 1.544Mbps) and E1 (European standard, bandwidth 2.048Mbps) are physical connection technologies, and my country's dedicated communication lines are generally E1. The voice digital signal transmitted in E1 / T1 adopts pulse code modulation (Pulse Code Modulation, PCM for short). For single-channel PCM, the system sampling frequency is 8000HZ, and the sampling interval is 125μs. The time of 125μs is divided into many time slots (TimeSlot, referred to as TS) for time distribution. Generally, E1 is divided into 32 time slots, and T1 is divided into For 24 time slots. Within 125μs, each time slot transmits an 8-bit code group in turn, which is called a frame, that is, on the E1 / T1 digital trunk line, the information transmission of each ti...
