Modem pass through for remote testing
First Claim
1. A network communication system for communicating information between a point of origin and a point of destination using a pass-through mode of tunneling through a packet switching network comprising:
- a first network access server coupled to the point of destination for communicating therebetween through a public switching telephone network and responsive to information from a second network access server originating at a point of origin through the public switching telephone network, said first network access server and said second network access server communicating therebetween through a packet switching network; and
a lab network access server coupled to the first network access server through the packet switching network and to the second network access server through the packet switching network, upon the point of origin establishing a call to the point of destination, through the second network access server and upon the second network access server failing to successfully communicate with the first network access server, said lab network access server responsive to a succeeding call from the second network access server using a pass-through mode of tunneling, through the packet switching network and terminating the succeeding call thereby allowing diagnosis and debugging of the failure associated with the second network access server at the location of the lab network access server.

Abstract
A lab network access server is disclosed in accordance with an embodiment of the present invention. The lab network access server is coupled to a customer network server through a packet switching network. The customer modem device includes a customer modem device and is coupled to an end-user modem device employed by an end-user. In a diagnostic scenario, the end-user initiates a call through the customer network access server modem device, which is setup for pass through operations. The customer network access server, upon receiving the call information, routes the call information to the lab network access server for termination thereof. The lab network access server operates to diagnose problems associated with the customer modem device and includes a lab modem device. Upon the customer modem device failing to successfully communicate with the end-user modem device, the lab modem device receives a succeeding call from the end-user modem device using a pass-through mode of tunneling, through the packet switch network, and terminates the succeeding call thereby allowing diagnosis and debugging of the failure associated with the customer modem device to be performed at the location of the lab network access server. In a modem wholesale scenario, the same setup is used as a service to terminate modem calls in a remote location when a customer only has voice-over-IP capabilities.

7. In a packet switching network environment employing a customer network access server, including a customer modem, coupled to a lab network access server, through a packet switching network, and to a first network access server, through a packet switching network, said lab network access being remotely located to the customer network access server, said packet switching network environment causing communications between a point of origin and a point of destination, a method of diagnosing problems associated with the customer modem comprising:
-
establishing a call from the point of origin to the point of destination, through the customer network access server and the first network access server;
failing to successfully communicate with the first network access server;
establishing a succeeding call from the customer network access server to the lab network access server using a pass-through mode of tunneling and through the packet switching network;
terminating the succeeding call; and
allowing for diagnosis and debugging of the failure associated with the customer network access server at the location of the lab network access server.

8. In a packet switching network environment employing a customer network access server, including a customer modem, coupled to a lab network access server, through a packet switching network, and to a first network access server, through a packet switching network, said lab network access being remotely located to the customer network access server, said packet switching network environment causing communications between a point of origin and a point of destination, a method of diagnosing problems associated with the customer modem comprising:
-
establishing a call from the point of origin to the point of destination, through the customer network access server and the first network access server;
failing to successfully communicate with the first network access server;
establishing a succeeding call, including voice signals, from the customer network access server to the lab network access server using a relay mode of tunneling and through the packet switching network wherein the voice signals are demodulated;
terminating the succeeding call; and
allowing for diagnosis and debugging of the failure associated with the customer network access server at the location of the lab network access server.
