  17. Owning to the network structure of the transactions from the outgoing calls to incoming calls, we therefore suggested that to transfer these 5 bureaus to the city network, i. e. 6975 and 6977 bureau be merged into t21, t23, t24, t12 and t6, 8049 bureau be merged into t42, t43, t44, t32 and t5, 8959 and 6957 bureau be merged into t42, t43, t44, t32 and t5. these direct trunking lines are used only for the tandem of the suburban traffic of this end office and its inter - network calls, while the long distance calls are dealt with by the auxiliary tandem office

    由於整個北京電話網的網路結構要由去話匯接方式向來去話匯接方式過渡，所以我們建議該5個局以來去話方式入大網，即6975 、 6977局入t21 、 t23 、 t24 、 t12 、 t6 ， 8049局入t42 、 t43 、 t44 、 t32 、 t5 ， 8959 、 6957局入t42 、 t43 、 t44 、 t32 、 t5 ，這些直達中繼只匯接本端局的市郊話務量和該端局的網間呼叫，長途呼叫仍由原輔助匯接局匯接。
  18. With the destination code analysis, it has been found that the 6975 bureau to the urban volume ( one way ) is 540erl, the 6977 bureau to the urban volume ( one way ) is 480erl, and the 6178 bureau nearly 200erl, plus the urban voice traffic volume of the incoming calls, the 6973 bureau and the 6970 bureau has tandemed the voice traffic volume nearly 1000erl. this has increased the auxiliary tandem office voice load, and at the same time, increased the demand for the trunking lines and has made pressure on the trunk module of the areas and counties

    經目的碼分析， 6975局到市內的話務量（單向）為540erl ， 6977局到市內的話務量（單向）為480erl ， 6178局到市內的話務量（單向）將近200erl ，再加上市內來話的話務量，使6973局和6970局為其他局轉接的話務量將近1000erl ，大大增加了輔助匯接局轉接的話務負荷，同時，端局到區、縣中心局，區、縣中心局到匯接局的中繼數量需求大，造成了區、縣中心局中繼模塊緊張的狀況。
