Abstract

The present invention discloses a far-end control system and method of telephone exchange, which comprises a controller exchange and a controllee exchange, wherein each exchange has a FSK transceiver, and a signal interconnecting relationship is formed between both exchanges via a telecommunication network. The controller exchange connects with a telephone set in the near end, transforms the keying signals of the telephone set into a string of FKS-encoded instructions, which are then transmitted to the far-end controllee exchange. The controllee exchange updates the system data according to the instructions and responds to the controller exchange with a string of FSK signals, which is then displayed on the telephone set. Via the transmission of FSK-encoded signals, and via the keying operations in the telephone set, the controller exchange can reprogram and control the controllee exchange from a far end. The present invention has advantages of easy and brief operation, diversified programming contents, cost saving, and time saving.

Claims

1. A far-end control system of telephone exchange, which performs a far-end control via the transmission of FSK (Frequency Shift Keying) signals, comprising:

a controller exchange, coupled to a telephone set, and having a built-in first FSK transceiver, which transforms keying signals of said telephone set into a FSK-encoded instruction and sends out said FSK-encoded instruction; and

a controllee exchange, having a signal interconnecting relationship with said controller exchange via connecting to a telecommunication network, and having a built-in second FSK transceiver, which updates system data according to received said FSK-encoded instruction and transforms a prompt message created by the system into a FSK signal and responds said prompt message to said controller exchange via said telecommunication network;

wherein via the transmission of said FSK-encoded signals and the keying operations in said telephone set, said controller exchange can reprogram and control said controllee exchange from a far end.

2. The far-end control system of telephone exchange according to claim 1, wherein said telephone set implements keying operations and displaying function, which enables said prompt message created by said congtrollee exchange to be displayed on said telephone set.

3. The far-end control system of telephone exchange according to claim 1 or claim 2, wherein said prompt message further comprises the recentest execution result and the reprogrammed system data.

4. The far-end control system of telephone exchange according to claim 1,

wherein said controller exchange further comprises:

an office-line interface, coupled to said first FSK transceiver, and providing a connection to said telecommunication network;

a database, coupled to said first FSK transceiver, and providing a storage memory for said system data; and

a touch-tone telephone interface, coupled to said database, and providing a connection to a telephone set.

5. The far-end control system of telephone exchange according to claim 1,

wherein said controllee exchange further comprises:

an office-line interface, coupled to said second FSK transceiver, and providing a connection to said telecommunication network;

a database, coupled to said second FSK transceiver, and providing a storage memory for said system data; and

a touch-tone telephone interface, coupled to said database, and providing a connection to a telephone set.

6. The far-end control system of telephone exchange according to claim 1, wherein said first FSK transceiver periodically transmits a FSK-encoded instruction to said coltrollee exchange, and said second FSK transceiver periodically transmits a prompt message to said controller exchange.

7. A far-end control method of telephone exchange, which performs a far-end control via the transmission of FSK (Frequency Shift Keying) signals, comprising the following steps:

providing a first exchange and a second exchange, wherein said two exchanges have a far-end interconnecting relationship via a telecommunication network and said first exchange is coupled to a telephone set in the near end; and

after said first exchange is connected with said second exchange, said first exchange transforming a keying signal of said telephone set into a FSK-encoded instruction and transmitting said FSK-encoded instruction to said second exchange to enable said second exchange to update system data and respond to said first exchange with a FSK prompt message;

wherein via the reciprocal transmission of said FSK-encoded signals between said two exchanges and the keying operations in said telephone set, said first exchange can reprogram and control said second exchange from a far end.

8. The far-end control method of telephone exchange according to claim 7, wherein said prompt message is displayed on said telephone set.

9. The far-end control method of telephone exchange according to claim 7 or claim 8, wherein said prompt message further comprises the recentest execution result and the reprogrammed system data.

10. The far-end control method of telephone exchange according to claim 7, wherein said second exchange can be connected with a telephone set.

11. The far-end control method of telephone exchange according to claim 7, wherein said first exchange periodically transmits a FSK-encoded instruction to said second exchange, and said second exchange periodically transmits a prompt message to said first exchange.
