Claims
- 1. A method of processing a call with a network adapter located at a digital network subscriber's premises, the network adapter operatively coupling a first communication device to a digital network and a telco switchover one of first and second communication channels, said method comprising the steps of:
- establishing a first call on the first communication device over the first communication channel,
- determining whether a second call is being made to the first communication device;
- connecting to the first communication device, the second call on the second communication channel without the first call being placed on hold by the telco switch; and in response to a toggle signal from the first communication device
- toggling between said first and second calls with said first communication device without either the first or second call being placed on hold by the telco switch.
- 2. The method according to claim 1, further including the step of:
- releasing one of said first and second communication channels in response to a disconnect request made by any one communication device connected to said first or second call.
- 3. The method according to claim 1, wherein said step of connecting said second call further comprises the steps of:
- determining whether said second communication channel is available only in response to a determination that said second call request is being made, and
- establishing a connection on said second communication channel only in response to a determination that the second communication channel is available.
- 4. The method according to claim 1, further including the steps of:
- receiving a setup message for a third call at said network adapter, and rejecting said third call.
- 5. The method according to claim 1, wherein the digital network comprises an Integrated Services Digital Network and the first and second communication channels comprise ISDN B-channels of a basic rate interface.
- 6. The method according to claim 1, wherein said communication device comprises a device selected from the group consisting of digital devices and analog devices.
- 7. The method according to claim 6, wherein said subscriber's premise includes analog and digital devices both of which are connected to the digital network via first and second pairs of conventional telephone wires, said first pair of wires operatively connected to said adapter and said digital network and said second pair of wires operatively connected to analog devices and said network adapter.
- 8. A method of processing a call with a network adapter apparatus located at a digital network subscriber's premises, the network adapter operatively coupling first and second communication devices at the subscriber's premises to a telco switch over first and second communication channels, the method comprising the steps of:
- A) receiving an incoming first call to the first communication device;
- B) establishing the first call on the first communication device over the first communication channel;
- C) receiving an incoming second call to the first communication device; and
- D) connecting the second call to the second communication channel; and in response to a toggle signal from the first communication device
- E) placing the first call on the first communication channel on hold without the intervention of the telco switch.
- 9. The method of claim 8 further comprising the steps of:
- F) in response to a toggle signal from the first communication device, reestablishing the first call by recoupling the communication device to the first communication channel without such recoupling being performed by the telco switch.
- 10. The method of claim 9 wherein step F further comprises:
- F.1) placing the second call on hold without the intervention of the telco switch.
- 11. The method of claim 8 wherein step D further comprises the steps of:
- D.1) determining whether the second communication channel is in use.
- 12. The method of claim 8 wherein the digital network comprises an Integrated Services Digital Network and the first and second communication channels comprise ISDN B-channels of a basic rate interface.
- 13. A method of processing calls with a network adapter apparatus located at a digital network subscriber's premises, the network adapter operatively coupling first and second communication devices located a the subscriber's premises to a telco switch over a digital network, the digital network comprising first and second communication channels, the method comprising the steps of:
- A) establishing a first call on the first communication device over the first communication channel; and
- B) connecting a second call to the second communication channel without the first call being placed on hold by the telco switch; and in response to a toggle signal from the first communication device
- C) toggling between the first and second calls on the first communication device without either of the first or second calls being placed on hold by the telco switch.
- 14. The method of claim 13 wherein the second communication device is coupled to the second communication channel and step B further comprises:
- B.1) connecting the second call to the second communication device.
- 15. The method according to claim 14 wherein step B further comprises:
- B.2) determining whether the second call request is being made to the subscriber's premises;
- B.3) determining whether the second communication channel is available only in response to a determination that the second call request is being made; and
- B.4) connecting the second call on the second communication channel to the first communication device only in response to determination that the second communication channel is available.
- 16. The method of claim 13 wherein the digital network comprises and Integrated Services Digital Network and the first and second communication channels comprise ISDN B-channels of a basic rate interface.
