1. A method of communication over a channel in a multicarrier modulation communications environment, the method comprising:
detecting a disturbance event on the channel;
determining a duration of the disturbance event;
identifying the disturbance event as a continuing disturbance event based on at least the determined duration of the disturbance event; and
in response to said identifying of the disturbance event as a continuing disturbance event, switching from a primary communication parameter set associated with the channel to a secondary communication parameter set associated with the channel;
wherein the disturbance event is based on a detection of a Cyclic Redundancy Check (CRC) failure and is determined to be a continuing disturbance event if the CRC failure continues over a threshold number of communication frames transmitted over the channel.
2. The method of claim 1, wherein the disturbance event is an on-hook or off-hook event associated with voice communications.
3. The method of claim 1, wherein the primary communication parameter set includes at least a primary specification of bit allocations for the channel, and wherein the secondary communication parameter set includes at least a secondary specification of bit allocations for the channel.
4. The method of claim 1, wherein the primary communication parameter set includes at least a primary gain setting for the channel, and wherein the secondary communication parameter set includes at least a secondary gain setting for the channel.
5. An apparatus configured to communicate over a channel in a multicarrier modulation communications environment, the apparatus comprising:
a control module coupled with a communication line and configured to receive signals from the communication line and to detect a Cyclic Redundancy Check (CRC) failure;
a transmitter coupled to the control module and configured to transmit signals from the apparatus;
a receiver coupled to the control module and configured to receive signals into the apparatus; and
a primary channel control table and a secondary channel control table;
wherein said control module is further configured to, upon detecting a continuing disturbance event on the channel, switch from the primary channel control table to the secondary channel control table for communication over the channel, wherein a disturbance event is determined to be the continuing disturbance event if the CRC failure continues over a threshold number of communication frames transmitted over the channel.
6. The apparatus of claim 5, wherein the primary channel control table includes at least a primary specification of bit allocations for the channel, and wherein the secondary channel control table includes at least a secondary specification of bit allocations for the channel.
7. The apparatus of claim 5, wherein the primary channel control table includes at least a primary gain setting for the channel, and wherein the secondary channel control table includes at least a secondary gain setting for the channel.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for testing the physical layer of a broadband installation at subscriber’s house by means of a broadband test device (NA) coupled to said subscriber’s house through a broadband connection (BB) and so adapted to perform measurements on said broadband installation,
characterized in that said method comprises the step of allowing an end-user at the subscriber’s house to dialog with said broadband test device (NA) through a responder device (IVR), said dialog comprising information received from said end-user and translated by said responder device into input control for said broadband test device and output control from said broadband test device translated by said responder device into instructions towards said end-user.
2. The method according to claim 1, characterized in that said method comprises the step of said broadband test device (NA) performing measurements on said broadband installation in accordance with said output control andor input control translated into instructions andor from information respectively.
3. The method according to claim 1,
characterized in that said method comprises the step of establishing the dialog between said end-user and said responder device (IVR) via a narrowband connection (NB),
and in that said responder device is a narrowband responder device.
4. The method according to claim 3, characterized in that said dialog comprises vocal instructions and vocal information.
5. The method according to claim 3, characterized in that said narrowband responder device is coupled to said narrowband connection (NB) via a Local Exchange (LEX).
6. The method according to claim 3, characterized in that said narrowband connection (NB) and said broadband connection (BB) use the same physical medium.
7. The method according to claim 3, characterized in that said narrowband connection (NB) and said broadband connection (BB) use a different physical medium.
8. The method according to claim 1, characterized in that said broadband connection (BB) is a Digital Subscriber Line (DSL).
9. The method according to claim 3, characterized in that said narrowband connection (NB) is a Plain Old Telephone Service (POTS) line.
10. The method according to claim 3, characterized in that said narrowband connection (NB) is a mobile phone connection.
11. A telecommunication test system for testing the physical layer of a broadband installation at subscriber’s house, said test system having a broadband test device (NA) coupled to said subscriber’s house through a broadband connection (BB) and so adapted to perform measurements on said broadband installation,
characterized in that said telecommunication test system further comprises a responder device (IVR) coupled to said broadband test device (NA) and adapted to exchange messages with an end-user at the subscriber’s house, said responder device being adapted to translate information received from said end-user into input control for said broadband test device, and to translate output control from said broadband test device into instructions towards said end-user.
12. The telecommunication test system according to claim 11, characterized in that said telecommunication test system further comprises a narrowband connection adapted to exchange vocal messages comprising vocal information and vocal instructions.
13. A responder device (IVR) for the telecommunication test system of claim 11,
characterized in that said responder device is a narrowband intelligent voice responder (IVR) adapted to exchange vocal messages with an end-user at the subscriber’s house via a narrowband connection (NB).
and in that said responder device is adapted to translate vocal information received from said end-user into input control for said broadband test device, and to translate output control from said broadband test device into vocal instructions towards said end-user.
14. The method according to claim 1, characterized in that said responder device (IVR) is a narrowband intelligent voice responder (IVR) adapted to exchange vocal messages with said end user at the subscriber’s house via a narrowband connection (NB), and is adapted to translate vocal information received from said end user into input control for said broadband test device, and to translate output control from said broadband test device into vocal instructions towards said end user.
