Abstract
Apparatus and method for establishing a communication link. A negotiation data transmitting section, associated with a plurality of initiating communication devices, transmits carriers to a responding communication device. A negotiation data receiving section, associated with the plurality of initiating communication devices, receives carriers from the responding communication device, in response to the transmitted carriers. A selecting device selects an appropriate communication device from the plurality of communication devices, in accordance with the responding communication device, in order to establish a communication channel.
Claims41
An apparatus for establishing a communication link, comprising:
- a negotiation data transmitting section, associated with a plurality of initiating communication devices, that transmits carriers to a responding communication device;
- a negotiation data receiving section, associated with the plurality of initiating communication devices, that receives carriers from said responding communication device, in response to said transmitted carriers, and
- a selecting device that selects an appropriate communication device from the plurality of communication devices, in accordance with said responding communication device, to establish a communication channel.
A method for establishing a communication link, comprising:
- transmitting predetermined carriers to a responding communication device;
- receiving predetermined carriers from the responding communication device, in response to the predetermined transmitted carriers, and
- selecting an appropriate communication device from a plurality of communication devices, in accordance with the received predetermined carriers, to establish a communication channel.
A communication device that at least one of transmits and receives a communication signal, comprising:
- a data exchanging device that exchanges data, between an initiating communicating device and a responding communication device, over a communication channel;
- and
- an implicit channel probe device that analyzes said exchanged data to assess characteristics of said communication channel.
A method for at least one of transmitting and receiving a communication signal, comprising:
- exchanging data between an initiating communicating device and a responding communication device, over a communication channel;
- and
- performing an implicit channel probe analysis on the exchanged data to assess characteristics of the communication channel.
A communication device, comprising:
- a communication device that initially transmits data with a multiplicity of carriers;
- and
- a carrier determining device that reduces said multiplicity of carriers transmitted by said communication device to a predetermined number of carriers, in accordance with a predetermined carrier reduction system.
A method for establishing a communication link, comprising:
- exchanging unmodulated carriers between an initiating communication device and a responding communication device, to negotiate a high speed communication link;
- and
- executing a fallback procedure to establish a predetermined communication link if one of the initiating communication device and the responding device is unable to process said unmodulated carriers for negotiating the high speed communication link.
A method for establishing a communication link between a first device and a second device, comprising:
- transmitting a first capabilities list to one of the first device and the second device;
- receiving a second capabilities list transmitted by a remaining one of the first device and the second device, in response to the first capabilities list;
- selecting an appropriate communication mode from a plurality of communication modes, in accordance with the second capabilities list, to establish the communication channel;
- and
- executing a simplified initialization procedure to re-establish the communication link in the event that one of the first device and the second device has entered a non-data exchange state and data is to be exchanged between the first device and second device.
A method for establishing a communication link between a first device and a second device, comprising:
- establishing common communication capabilities between the first device and the second device;
- selecting an appropriate communication mode from a plurality of communication modes, in accordance with the established common communication capabilities;
- and
- executing a simplified initialization procedure to re-establish the communication link in the event that one of the first device and the second device has entered a non-data exchange state and data is to be exchanged between the first device and second device.
A method for establishing a communication link, comprising:
- executing a negotiation protocol in order to establish a communication link between a first communication device and a second communication device;
- maintaining a carrier of the negotiation protocol upon establishing the communication link, to serve as an embedded operations channel.
A communication device, comprising:
- means for performing a handshake communication procedure;
- and
- means for configuring handshake communication parameters from a terminal using a Simple Network Management Protocol.
A communication method, comprising:
- using an Administration, Operations, and Management (AOM) Simple Network Management Protocol (SNMP) to configure and monitor a handshake procedure for establishing a high speed communication link
