Abstract

This invention relates to a communication information process and transmission system of digital information including a SDH cross device and an ATM switch device, in which, the ATM switch device switches the ATM NE by the ATM switch unit to finish the port accumulation and to accumulate the IMA or ATM service to the STM interface unit to be output or sent to the far end by a SDH cross device characterizing that the ATM includes a transformation unit of multiple signals processing related signals and including a VC-4&, VC-4-xV ATM transformation unit and an E3 ATM conversion unit and an IMA port expanding unit is set between the ATM switch unit and the IMA conversion unit.

Description

technical field [0001] The invention relates to digital information transmission, in particular to a communication information processing and transmission system. Background technique [0002] The goal of the 3G network is flat networking and IP-based transmission. Currently, time division multiplexing TDM / asynchronous transfer mode ATM transmission is relatively mature. This relatively mature 3G network is mainly based on ATM packet technology. The radio link controller RNC and NodeBs (logic nodes for WCDMA wireless access) carry services through ATM cells, and applications mainly come from static data services such as short messages and Internet access. [0003] The uplink bandwidth of the 3G base station is 2M ~ 8M, and the maximum will not exceed 16M. Utilizing existing copper cable resources, using one or more cables to transmit E1 signals in IMA (Inverse Multiplex of ATM: ATM inverse multiplexing) mode is a better implementation method. The standard interface of 3G ba...
