A switch proxy comprising a controller, a translations database and a switching fabric are connected to a trunk group between a remote terminal and its controlling local switching system. The switch proxy monitors control signals to and from the switching system on the trunk. In the event of loss of control signals from the host switching system, the switch proxy intercepts requests for service, etc. from a calling telephone connected to the remote terminal and performs a look up in the translation database. If the call can be completed without the controlling switching system the call is looped back to the remote terminal. The translation database is maintained by a switch proxy management system that receives change orders from the local exchange carrier. The switch proxy management system forwards relevant changes to the switch proxy's translation database in the field.
A switch proxy apparatus for controlling a remote terminal when said remote terminal is isolated from its controlling local switching system wherein:
A method for controlling a switch proxy, said switch proxy connected on a trunk between a remote terminal and a local switching system that controls the remote terminal, said method comprising:
A method for operation of a switch proxy controlling a remote terminal when said remote terminal is isolated from its controlling local switching system and a subscriber originating a 9-1-1 call has been detected on said remote terminal, said method comprising:
A switch proxy management system apparatus for maintaining a switch proxy translations database within a switch proxy synchronized with a local switching system translations database and current 9-1-1 emergency responder information comprising:
