The application of stm - 1 on the exchange network also implies substantive influence on the development of the whole transmission network , which used to provide only 2mbits circuits and seldom put in use 155mbits ones . so if too many 155mbits circuits were applied , it would be difficult for the current sdh network to fit in . that is why a 155mbits - granularity broadband sdh platform is in need
使用交换机stm - 1组网对整个传输网的发展也将产生重大影响，因为过去传输网都是以提供2mbits电路为目标，很少使用155mbits用户电路，如果大量使用155mbits电路，目前的sdh网势必难以适应，需要建设155mbits颗粒的宽带sdh平台。
