Patent ID: 7646720

Claim:
A remote service testing system comprising: a first plurality of nodes configured to transmit first communications in an Ethernet format; a first multiplexing system coupled to the first plurality of nodes and configured to receive the first communications in the Ethernet format and transfer the first communications in the Ethernet format over a first plurality of time division multiplexed (TDM) circuits in a first network extension; a second multiplexing system coupled to the first multiplexing system by the first network extension and configured to receive the first communications in the Ethernet format over the first plurality of TDM circuits and transfer the first communications in the Ethernet format to an Internet; and a service analyzer coupled to the second multiplexing system and configured to instruct the second multiplexing system to re-route a one of the first plurality of TDM circuits to the service analyzer and perform test functions on re-routed first communications associated with the one of the first plurality of TDM circuits; a second plurality of nodes configured to transmit second communications in an Ethernet format; a third multiplexing system coupled to the second plurality of nodes and configured to receive the second communications in the Ethernet format over a second plurality of TDM circuits in a second network extension; the second multiplexing system coupled to the third multiplexing system by the second network extension and configured to receive the second communications in the Ethernet format over the second plurality of TDM circuits and transfer the second communications in the Ethernet format to the Internet; and the service analyzer configured to instruct the second multiplexing system to re-route a one of the second plurality of TDM circuits to the service analyzer and perform test functions on re-routed second communications associated with the one of the second plurality of TDM circuits.
