Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] According to a specific embodiment of the present invention, a kind of SS7 acquisition system time slot / data exchange controller (SuperDXC) is provided, each SuperDXC extracts 64Kbit / s time slot from 256 or 64 2Mbit / sE1 signals, These 64Kbit / s time slots are synthesized into 16, 64 or 128 2M signal outputs after synchronizing and switching the matrix, so as to realize the crossing and duplication of multiple E1 signals. SuperDXC includes the following modules:

[0032] The switching control board module is used to control the operation of each part of the equipment and receive control comma...

Abstract

The invention provides a signalling system 7 collection system slot-time/data exchanging controller which comprises an exchanging control board module, one or a plurality of line interface board modules, one or a plurality of back line-out board modules and a back board module. The signalling system 7 collection system slot-time/data exchanging controller is powerful in link processing capacity and has highly reliable access, and a physical link has automatic error redundancy processing capacity. The invention further provides a gain redundancy processing method of an E 1 link.

Description

technical field [0001] The invention belongs to the application field of communication technology, and in particular relates to E1-based No. 7 signaling channel detection, a time slot / data exchange controller of a No. 7 signaling acquisition system and a realization method thereof. Background technique [0002] PCM (Pulse Code Modulation), that is, pulse code modulation, is a technology that converts analog signals (such as voice) into digital signals suitable for transmission through sampling, quantization and coding. [0003] PCM technology is widely used in telecommunication networks. In PCM lines, the most commonly used line code type is HDB3 code (HighDensity Bipoiar3), and HDB3 code is used in E1. A link of each E1 has 32 time slots. Time slot 0 is used for frame delimitation, and other remaining time slots can transmit both data and voice, and the 16th time slot generally transmits signaling. The time slot / data exchange controller (SuperDXC) of the No. 7 signaling c...
