Based on the results, beijing telecom has forwarded its suggestions to relevant vendors, who in turn have made a number of improvements in their later product versions. with the stm - 1 link as the inter - office trunk, the number of ddfs will be markedly reduced, thus saving floor space in the pit and wiping off distribution - related failures. besides, the number of outgoing trunks will be brought down, thus demanding less maintenance staff and improving the maintenance efficiency
交換機利用stm - 1鏈路作為局間中繼線路，可以減少數字配線架ddf的數量與規模，從而大大節省局房佔用面積，解決局房面積緊張的問題；還可大大減少配線數量，去除因配線引起的故障；另外，交換機利用stm - 1鏈路作為局間中繼線路，可以減少出局中繼線路數量，從而可以減少維護人員對中繼線路進行維護的工作量，提高維護效率。
