    • Pluggable communication modules, e.g. SFP, XFP, XENPAK, on a service provider's packet switched network will include network monitoring capability, e.g. Intelligent Pluggable Modules. The Intelligent Pluggable Modules are configured to detect emergency calls. When an emergency call is detected, the module notifies a software application of the detected call, including the Media Access Controller (MAC) address of the caller. The application then queries the network equipment, typically the Digital Subscriber Line Access Multiplexer for the ingress port of the MAC address using a protocol such as SNMP. Upon receipt, the service provider's customer database is then queried for the physical port location corresponding to the MAC address. The management station then sends the physical location into the existing 911 system.
    • 可插拔通信模块,例如 SFP,XFP,XENPAK在服务提供商的分组交换网络上将包括网络监控能力,例如, 智能可插拔模块 智能可插拔模块配置为检测紧急呼叫。 当检测到紧急呼叫时,模块向软件应用通知检测到的呼叫,包括呼叫者的媒体接入控制器(MAC)地址。 应用程序然后使用诸如SNMP的协议来查询网络设备,通常是用于MAC地址的入口端口的数字用户线路接入复用器。 接收到后,就会查询与MAC地址对应的物理端口位置的服务提供商的客户数据库。 然后,管理站将物理位置发送到现有的911系统。
