Abstract

The ISDN remote wake-up method includes the steps: checking an acknowledgement response signal received at a terminal-end device (TE) of an ISDN; comparing the content of a certain register with the wake-up information content in the acknowledgement response signal received at the TE, wherein the wake-up information includes a wake-up signal and an identifying value of an ISDN device; storing the wake-up information on a specific IC when the comparison result is identified; and performing the wake-up action to the ISDN device at the power-down mode based on the stored wake-up information.

Claims

1. An ISDN remote wake-up method, comprising the steps of:

checking an acknowledgement response signal received at a terminal-end device (TE) of an ISDN;

comparing the content of a certain register with the wake-up information content in the acknowledgement response signal received at the TE, wherein the wake-up information includes a wake-up signal and an identifying value of an ISDN device;

storing the wake-up information on a specific IC when the comparison result is identified; and

performing the wake-up action to the ISDN device at the power-down mode based on the stored wake-up information.

2. The ISDN remote wake-up method as claimed in claim 1, wherein the terminal-end device further comprises at least ISDN equipment, an ISDN terminal, and a bus interface coupled between the ISDN equipment and the ISDN terminal.

3. The ISDN remote wake up method as claimed in claim 2, wherein the bus interface is capable of supporting a multi-media system.

4. The ISDN remote wake-up method as claimed in claim 1, wherein the acknowledgement response signal is a specific signal belonging to the ISDN protocol.

5. The ISDN remote wake-up method as claimed in claim 4, wherein the step of checking an acknowledgement response signal is achieved by checking the 13^th bit of the acknowledgement response signal for logic ‘

1’

to determine that the terminal-end device (TE) has received the acknowledgement response signal.

6. The ISDN remote wake-up method as claimed in claim 1, wherein the wake up information is conformed to the HDLC standard.

7. The ISDN remote wake-up method as claimed in claim 1, wherein the wake-up information comprises a wake-up signal address value and a device representation value.

8. The ISDN remote wake-up method as claimed in claim 7, wherein the wake-up signal address value and the device representation value are changeable.

9. The ISDN remote wake-up method as claimed in claim 7, wherein the content in the wake-up signal address value is a pair of ISDN incoming call value as a wake-up signal.

10. The ISDN remote wake-up method as claimed in claim 7, wherein the content in the device representation value indicates the device at the power-down mode chosen to be woken up.

11. The ISDN remote wake-up method as claimed in claim 1, wherein the storage is a memory structure capable of storing and updating data.

12. The ISDN remote wake-up method as claimed in claim 11, wherein the memory structure is any register, SRAM, FIFO or combination thereof.

13. The ISDN remote wake-up method as claimed in claim 1, wherein the certain register further comprises an address register and an address mask register which are stored on a specific integrated circuit (IC).

14. The ISDN remote wake-up method as claimed in claim 13, wherein data stored on the specific integrated circuit (IC), including the content of the wake-up signal, is kept due to a standby power even if the TE enter the power-down mode.

15. The ISDN remote wake-up method as claimed in claim 14, wherein the standby power is provided by the ISDN equipment or ISDN terminal.

16. The ISDN remote wake-up method as claimed in claim 1, wherein the step of performing the wake-up action is performed by specific protocol according to the bus interface between ISDN equipment and ISDN terminal.

17. The ISDN remote wake-up method as claimed in claim 16, wherein the content of the wake-up signal in ISDN equipment is output to ISDN terminal after ISDN terminal is waken up.
