【摘要】 现代传输网开始向着智能化方向发展,数字传送技术是关键。在支持可变比特率和高突发性业务方面,ATM比SDH更具优势。采用由高鸿公司开发的基于ATM ADM的新型传送网/接入网设备AP900在业务提供、带宽利用、节省投资等方面比采用SDH技术更具竞争力。更多还原

【Abstract】 The modern transmission network is becoming increasingly intelligentand digital transmission technology plays a key role in the shift. For support tovariable bit rate and bursty traffic, ATM is superior over SDH. AP900----theATM-ADM-based transport network/ access network equipment newly developed by Gao Hong Co. is more competitive than SDH technologies in service provisioning, bandwidth utilization and cost saving.更多还原
