Abstract
A communication system that includes a first modem and a second modem that establishes a communication link between the first modem and the second modem. The communication link has a first set of communication characteristics including a first communication channel or group of communication channels through which at least data is exchanged and a second communication channel through which no data is exchanged. Either the first modem or the second modem is configured to signal for a change, via the second communication channel, in the first set of communication characteristics.
Claims18
A communication system comprising:
- a first modem;
- a second modem that establishes a communication link between the first modem and the second modem;
- the communication link having a first set of communication characteristics including a first communication channel or group of communication channels through which at least data is exchanged and a second communication channel through which no data is exchanged;
- and
- either the first modem or the second modem being configured to signal for a change, via the second communication channel, in the first set of communication characteristics, wherein the first modem is configured to signal for a change in the first set of communication characteristics via the second communication channel and the second modem is configured to dismiss the signal from the first modem on the second communication channel.
A communication system comprising:
- a first modem;
- a second modem that establishes a communication link between the first modem and the second modem;
- the communication link having a first set of communication characteristics including a first communication channel or group of communication channels through which at least data is exchanged and a second communication channel through which no data is exchanged;
- and
- either the first modem or the second modem being configured to signal for a change, via the second communication channel, in the first set of communication characteristics, wherein the first modem is configured to signal for a change in the first set of communication characteristics via the second communication channel and the second modem is configured to recognize and respond to the signal, and wherein the first modem includes transition processing circuitry that monitors the first set of communication characteristics between the first and second modems, that indicates when communications via the communication link may be improved by shifting to a second set of communication characteristics on the communication link, and that enables a shift in the communication link to the second set of communication characteristics.
A method for a communication system having a communication link between a first communication device and a second communication device to inquire whether a first set of communication characteristics in the communication link may be modified, the method comprising:
- establishing at least first and second communication channels across the communication link, the first communication channel exchanging at least data according to the first set of communication characteristics, the second communication channel exchanging no data;
- and
- inquiring, by the first communication device across the second communication channel, whether the second communication device recognizes communications across the second communication channel.
A communication system comprising:
- a source communication device;
- a destination communication device;
- a communication link having a first set of communication characteristics for electronic communications between the source communication device and the destination communication device;
- the source communication device including circuitry that generates a request signal to establish at least one communication channel with the destination communication device across the communication link;
- the destination communication device including circuitry that receives and acknowledges the request signal from the source communication device and that completes establishment of the at least one communication channel;
- and
- the destination communication device including an indicator that indicates to the source communication device that the first set of communication characteristics in the communication link should be modified and a second set of communication characteristics should be established.
