Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] The networking logic of the 2M ring is as follows: figure 1 As shown, the center and nodes A, B, and C are connected to each other through 2M lines, that is, the download port of the center is connected to the upload port of node A, the download port of node A is connected to the upload port of node B, and finally the download port of node C Returning to the upload ports in the center, 2M-1 to 2M-4 were used respectively. Since the 2M line is bidirectional between TX and RX, it can be clearly seen from the figure that all TX lines from 2M-1 to 2M-4 are connected to form a logical outer ring, and all RX connections form a logical inner ring, and the two rings are interconnected. for the reverse.

[0046] A 2M consists of 32 time slots, of which the 0th time slot is used for 2M frame synchronization, and the remaining time slots are used for data transmission.

Abstract

The invention relates to a parallel sending and selective receiving adverse bidirectional 2M ring and a design method thereof. The current 2M ring cannot realize bidirectional adverse transmission and environmental protection, can only realize chain shape protection, and cannot realize single-ring networking. For the 2M ring of the invention, the central node is connected with each base station node through 2M channels; a logical channel is formed on the outer sides and the inner sides of all 2M channels respectively; the logical channels of the outer sides and the inner sides are mutually adverse in direction; the logical channel of the outer sides and the logical channel of the inner sides are divided into three parts by taking time slot as a unit, including a network tube, an uplink and a downlink; any one logical channel of the logical channels of the outer sides and the inner sides can realize bidirectional non-uniform routing transmission between the central node and the base station node; and the simultaneous working of the logical channel of the outer sides and the logical channel of the inner sides can realize the parallel sending and selective receiving adverse bidirectional 2M ring. The parallel sending and selective receiving adverse bidirectional 2M ring makes two completely independent data trends exist between each base station node and the central node to realize backup transmission of data.

Description

technical field [0001] The invention belongs to the technical field of SDH data communication and loop network architecture, and relates to a concurrent selective reception reverse bidirectional 2M loop and a design method thereof. Background technique [0002] At present, in the base station information transformation and dynamic environment monitoring projects of operators, there are generally three transmission methods using 2M under SDH (Synchronous Transmission System) as the medium: point-to-point 2M transmission mode, based on BSC (base station controller) and BTS (base station Transceiver) back-inserted 64K slotting mode and 2M ring networking mode. Among them, 2M ring networking is often used when 2M resources are relatively tight and independent transmission networking is required for monitoring. In the 2M ring network, the center and the nodes are connected to each other using 2M, and each node shares the 2M bandwidth, and generally needs to collect serial port d...
