Abstract
A network device and a method for its operation are disclosed. The network device has a first interface to a client device to allow reception of client device signals and a second interface to a packet network to allow transmission and reception of modem relay signals. A processor translates between modem relay signals received or transmitted on the second interface and client device signals received or transmitted on the first interface. In one implementation the modem relay originator and the client device are collapsed into one device and the first interface is implemented as a virtual interface.
Claims29
A network device, comprising:
- a first interface to a client device to allow reception of client device signals;
- a second interface to a packet network to allow transmission and reception of modem relay signals;
- and
- a processor to translate between modem relay signals and client device signals.
A method of providing modem relay capability, the method comprising:
- receiving signals from a client device to initiate a network connection;
- identifying a terminating gateway based upon the signals from the client device;
- initiating a packet network call with the terminating gateway;
- receiving answer signals from the terminating gateway;
- and
- establishing a modem relay session with the terminating gateway.
A network device, comprising:
- a first means for providing an interface to a client device to allow reception of client device signals;
- a second means for providing an interface to a packet network to allow transmission and reception of modem relay signals;
- and
- a means for translating between modem relay signals and client device signals.
An article of machine-readable media containing code that, when executed, causes the machine to:
- receive signals from a client device indicating initiation of a modem relay session;
- identify a terminating gateway based upon the signals from the client device;
- initiate a packet network call with the terminating gateway;
- receive answer signals from the terminating gateway;
- and
- establish a modem relay session with the terminating gateway.
