therefore, a wise technological choice is very crucial when new equipment is introduced to access the network . in order to give play to the benefits of the backbone network, the choice of stm-1 as its basic granule should be a prerequisite . in the network build-up stage, the equipment for carrying services and the access equipment must adapt to the need of broadband evolution 因此,要十分重視新設(shè)備入網(wǎng)的技術(shù)選型,在骨干網(wǎng)絡(luò)以stm-1為基本顆粒的條件下,讓骨干網(wǎng)充分發(fā)揮它的效能,必須在確定建網(wǎng)的同時(shí),要確定各種承載業(yè)務(wù)的設(shè)備,接入設(shè)備應(yīng)符合向網(wǎng)絡(luò)寬帶化演進(jìn)的要求。
