Abstract
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.
