At present , we can track the signaling links in the 155 mbs ports of a switch only by using the signaling of the switch itself rather than the external analyzer of the ccs 7 . this causes inconvenience to maintenance . it is expected that manufacturers will enhance the tracking and monitoring functionality of their products and training switching and maintenance personnel concerning routine maintenance of the 155 mbs port 目前,我們只能利用交換機本身的信令觀察手段對交換機155mbits端口中的信令鏈路進行跟蹤、分析,而不能通過外掛七號信令分析儀對信令進行監(jiān)測,給維護工作帶來了不便,有待于生產(chǎn)交換機的廠家加強這方面的功能。
