This standard specifies the capabilities required to provide the network routing and transfer features associated with emergency service calls. Routing, Bridging, and Transfer of Emergency Service Calls (RBTESC) allows emergency service calls to be completed through the network to an appropriate emergency service attendant, and to provide the emergency service attendant with the ability to bridge to any other attendant in the emergency serving area with full feature functionality (that is, each attendant who handles a particular emergency service call is provided with an identifier that locates the source of the call, an indication whether the call is a high-priority call (e.g., hospitals, chemical plants, nursing homes), and the network addresses of emergency service agencies, which are specific to the caller's geographic area). It also allows for the transport and identification emergency service calls without the use of dedicated facilities. The interface between the attendants and their respective serving networks are beyond the scope of this standard. Formerly known as T1.628-2000(R2005).
