| 1. | On the one hand , we can use tandem switches in pairs and let them share traffic loads
一方面，将汇接交换机成对使用，利用汇接交换机本身进行负荷分担。 |
| 2. | Owing to the thick line bundle between tandem switches , 126 2 mbs trunk circuits are needed
由于汇接交换机之间的线束比较大，需要126条2mbits中继电路。 |
| 3. | In networking the four p3s tandem switches introduced recently , beijing telecom considered the following points
下面将对不同的应用情况下，分别采用两种速率的组网方式作以比较。 |
| 4. | The tandem switch is directly connected to 10 g transmission equipment via two 155 mbs coaxial cables , saving adm41 or adm161 equipment
汇接交换机直接与10g传输设备经过2条155mbits的同轴电缆进行连接，节省了adm41或adm161设备的使用。 |
| 5. | With the 2 mbits trunk , a full - capacity 128 k tandem switch needs 45 shelves while with the 155 mbits trunk , it only needs 21 shelves
一个128k的满容量的汇接交换机，如采用2mbits中继，需要４ ５个机架，采用155mbits中继，只需２ １个机架。 |
| 6. | A digital central office switching system made by lucent . it is typically used as an " tandem switching office , switching long distance phone calls . see 5ess
朗讯公司生产的一种数字市话局交换系统。通常作为一种汇接交换局，转接长途电话。参见5ess 。 |
| 7. | We consider the 155 mbs port most suitable for high capacity switches with thick trunk line bundles , such as tandem switches and interconnected and interworking gateways
将传输网与交换网综合考虑，结合带宽特点，我们认为： 155mbits端口最适合于那些大容量、大中继线束的交换机采用。 |
| 8. | Lucent technologies exs platform enables development of comprehensive application products including wireline and wireless open value - added platform , terminal office switching platform , tandem switching and international gateway
基于朗讯科技exs平台可开发全方位应用产品，包括有线、无线、开放增值平台、端局交换平台、汇接交换和国际网关等。 |
| 9. | As a result , at all these connection points , the two coaxial cables are connected to different transmission equipment , sharing the traffic load from the tandem switch to a given end exchange , with half of the respective trunk circuits put into use , ensuring network safety . for such connectivity , see figure 4
因此，在所有的同轴电缆连接处，都采用两条同轴电缆接到不同的传输设备的方法，将汇接交换机到某一端局的话务量在这两条同轴连接上进行负荷分担，中继电路各开一半，从而保证网络的安全性。 |
| 10. | The tandem switch must first be connected to the transmission equipment providing 2 mbs ports and to the transmission equipment in other tandem area via high - speed ( e . g . 10 gbs ) transmission equipment , and then to digital access and cross - connect system ( dacs ) . it is further connected to the corresponding sdh sub - ring after the vc - 12 level cross - connection carried out by the dacs and finally reaches the end exchange
汇接交换机首先需要连接到提供2mbs端口的传输设备，而后经高速率的传输设备（如10gbs ）到达其它汇接区的传输设备上，再接入到交叉连接设备（ dacs ）上，经dacs进行vc - 12级别的交叉连接，接到各个相应的sdh子环中，最终到达端局交换机。 |
