A method for effecting communications, such as telephone calls, accesses to data network sites, alarm system communications, and/or other communications, over a communications network. The method comprises: determining that an ability of first end-user equipment at a first end-user premise to communicate via a first communication link connecting the first end-user equipment to the communications network is disrupted; establishing a wireless communication link between the first end-user equipment and second end-user equipment at a second end-user premise; and causing information transmitted by or destined for the first end-user equipment to be exchanged over the communications network via the wireless communication link and a second communication link connecting the second end-user equipment to the communications network. Also provided are apparatus and computer-readable media containing a program element executable by a computing system to perform such a method.

The invention claimed is: 1. A method for effecting a communication over a communications network, said method comprising: determining that an ability of first end-user equipment at a first end-user premise to communicate via a first communication link connecting the first end-user equipment to the communications network is disrupted; establishing a wireless communication link between the first end-user equipment and second end-user equipment at a second end-user premise upon the ability of the first end-user equipment to communicate via the first communication link being determined to be disrupted; and causing information pertaining to the communication to be exchanged between the first end-user equipment and the communications network via the wireless communication link and a second communication link connecting the second end-user equipment to the communications network. 2. A method as claimed in claim 1 , said determining comprising verifying the ability of the first end-user equipment to communicate via the first communication link. 3. A method as claimed in claim 2 , said verifying comprising: performing a verification of a state of the first communication link based on a signal conveyable via the first communication link; and determining that the first communication link is disrupted based on a result of the verification. 4. A method as claimed in claim 3 , said determining that the first communication link is disrupted based on a result of the verification comprising determining that the signal is not received within a period of time or does not satisfy a quality-of-service condition. 5. A method as claimed in claim 2 , said verifying comprising: performing a verification of a state of a software or hardware component of the first end-user equipment; and determining that the software or hardware component of the first end-user equipment is disrupted based on a result of the verification. 6. A method as claimed in claim 1 , said determining comprising receiving information indicative of a disruption of the ability of the first end-user equipment to communicate via the first communication link. 7. A method as claimed in claim 6 , the information indicative of a disruption of the ability of the first end-user equipment to communicate via the first communication link comprising information indicative of a disruption of the first communication link. 8. A method as claimed in claim 1 , said establishing comprising causing a first one of the first end-user equipment and the second end-user equipment to wirelessly transmit certain information to a second one of the first end-user equipment and the second end-user equipment to establish the wireless communication link. 9. A method as claimed in claim 8 , the certain information comprising an identifier of the second end-user equipment. 10. A method as claimed in claim 9 , the identifier of the second end-user equipment comprising at least one of a hardware identifier and an IP address. 11. A method as claimed in claim 10 , the hardware identifier comprising at least one of a MAC address and an Ethernet hardware address. 12. A method as claimed in claim 9 , the certain information comprising access information for the second end-user equipment. 13. A method as claimed in claim 12 , the access information for the second end-user equipment comprising at least one of a password and a wireless network key. 14. A method as claimed in claim 12 , the certain information comprising an identifier of the first end-user equipment. 15. A method as claimed in claim 14 , each of the identifier of the first end-user equipment and the identifier of the second end-user equipment comprising at least one of a hardware identifier and an IP address. 16. A method as claimed in claim 15 , the hardware identifier comprising at least one of a MAC address and an Ethernet hardware address. 17. A method as claimed in claim 14 , the certain information comprising access information for the first end-user equipment. 18. A method as claimed in claim 17 , each of the access information for the first end-user equipment and the access information for the second end-user equipment comprising at least one of a password and a wireless network key. 19. A method as claimed in claim 1 , the first-end user equipment comprising a communication apparatus connected to the first communication link and to an end-user device at the first end-user premise, said method being performed by the communication apparatus. 20. A method as claimed in claim 19 , said establishing comprising wirelessly transmitting certain information to the second end-user equipment to establish the wireless communication link between the communication apparatus and the second end-user equipment. 21. A method as claimed in claim 20 , the second end-user equipment comprising a communication apparatus connected to the second communication link and to an end-user device at the second end-user premise, said wirelessly transmitting comprising wirelessly transmitting the certain information to the communication apparatus of the second end-user equipment to establish the wireless communication link between the communication apparatus of the first end-user equipment and the communication apparatus of the second end-user equipment. 22. A method as claimed in claim 20 , the second end-user equipment comprising a communication apparatus connected to the second communication link and to an end-user device at the second end-user premise, said wirelessly transmitting comprising wirelessly transmitting the certain information to the end-user device at the second end-user premise to establish the wireless communication link between the communication apparatus of the first end-user equipment and the end-user device at the second end-user premise. 23. A method as claimed in claim 19 , said establishing comprising causing the end-user device at the first end-user premise to wirelessly transmit certain information to the second end-user equipment to establish the wireless communication link between the end-user device at the first end-user premise and the second end-user equipment. 24. A method as claimed in claim 19 , comprising, prior to said determining, receiving a request for the communication to be effected over the communications network from the end-user device. 25. A method as claimed in claim 1 , said method being performed by an apparatus residing in the communications network. 26. A method as claimed in claim 1 , the communication being one of a telephone call effected using the first end-user equipment, an access to a data network site effected using the first end-user equipment, and an alarm system communication effected using the first end-user equipment. 27. Apparatus for effecting a communication over a communications network, said apparatus comprising: a processing entity configured to determine that an ability of first end-user equipment at a first end-user premise to communicate via a first communication link connecting the first end-user equipment to the communications network is disrupted; and a routing entity configured to: establish a wireless communication link between the first end-user equipment and second end-user equipment at a second end-user premise upon the ability of the first end-user equipment to communicate via the first communication link being determined to be disrupted; and cause inf
