DSL terminal-exchange device connecting system and method
A DSL 5 is connected between an exchange device 3 and an IAD 1 to which DSL subscriber terminals 2 - 1 through 2 -n are connected, and the exchange device 3 is equipped with a VMG 4 for terminating an ATM cell multiplexed over the DSL 5 , a voice packet transmitted as multiplexed over the DSL 5 is directly terminated at the exchange device 3 , which in turn converts the voice packet into a packet according to an existing exchange device interface 8 , so that DSL subscribers can be accommodated in the exchange device 3 directly and also exchange device software for operating the exchange device 3 can control call processing without knowing about a device under the control of a subscriber control unit, as a result, user burdens can be mitigated.
1. A network device to connect to a digital subscriber line (DSL), the network device comprising:
a voice media gateway (VMG) to terminate multiplexed voice data received via the DSL;
a first processing unit to divide the terminated multiplexed voice data into a voice signal and a call control signal;
a second processing unit to convert the call control signal into network device control data;
a signaling gateway controller to convert the network device control data into data in a control interface format;
a digital signal processor to convert the voice signal into voice packets; and
a multiplexer for multiplexing the voice packets and the data in the control interface format.
2. The network device of claim 1 , wherein the VMG comprises:
a terminating unit to directly terminate the multiplexed voice data.
3. The network device of claim 1 , wherein the VMG comprises:
the processing unit;
the digital signal processor; and
the multiplexer.
4. The network device of claim 3 , wherein the digital signal processor is configured to convert the voice signal from a 32 k to a 64 k adaptive differential pulse code modulation.
5. The network device of claim 3 , further comprising:
a control device interface; and
a control unit to receive the multiplexed voice packets and the multiplexed control signal via the control device interface.
6. A voice over digital subscriber line (VoDSL) communication system comprising:
means for extracting voice data from a received VoDSL signal;
means for dividing the extracted voice data into a voice signal and a call control signal;
means for processing the voice signal into voice packets;
means for converting the call control signal into control data;
means for converting the control data into data in a control interface format;
means for selectively multiplexing and demultiplexing the data in the control interface format and the voice packets for transfer to a control unit via a control unit interface.
7. An exchange device comprising: logic to:
receive multiplexed voice data from an integrated access device via a digital subscriber line (DSL); and
directly terminate the received multiplexed voice data.
8. The exchange device of claim 7 , wherein the logic is further configured to:
divide the terminated multiplexed data into parts including a voice signal and a call control signal.
9. The exchange device of claim 8 , wherein the logic is further configured to:
convert the voice signal into modulated data.
10. The exchange device of claim 9 , wherein the logic is further configured to:
selectively multiplex and demultiplex the modulated data.
11. The exchange device of claim 8 , wherein the logic is further configured to:
convert the call control signal into exchange device control data.
12. The exchange device of claim 11 , wherein the logic is further configured to:
selectively multiplex and demultiplex the exchange device control data.
13. The exchange device of claim 7 , wherein the logic is further configured to:
convert the terminated multiplexed voice data based on a control device interface associated with the exchange device.
14. A method comprising:
receiving voice data via a digital subscriber line; and
terminating the received voice data using a voice media gateway (VMG), said terminating including: (next line)
dividing the received voice data into components including a voice signal and a call control signal;
processing of the voice signal into voice packets;
converting the call control signal into control data in a control interface format; and
selectively multiplexing and demultiplexing the control data and the voice packets.
15. The method of claim 14 , further comprising:
transferring the multiplexed control data and voice packets to a control unit via a control unit interface.
16. The method of claim 14 , further comprising:
converting the voice packets from 32 k to 64 k adaptive differential pulse code modulation.
17. The method of claim 14 , wherein the terminating the received voice data further comprises:
directly terminating the received voice data using a DSL •IF terminating unit.
