Introduction to the AT instruction set of e-tech 717e

ByTalent Studio (finishing)

E-Tech's external TA 717 and 717E have no sets of setup tools that can only be set to set some basic functions with the AT extension instruction set. It is not convenient to use. Below I will show some of the more practical features that use the AT command set in the Hyper Terminus.

The Hyper Terminals that run the Win95, select the E-Tech DRIVE to build a connection, you can type the AT instruction set at the Hyper Terminal window. 1. View the latest setting information of TA AT & V

2. Set the TA's ISDN number (generally do not need to be set, but if your ISDN simulation port is not working properly, only the phone can only be called, not access the phone, etc. You can use this method to solve it)

AT! N0 = 50581550 (your ISDN phone number)

AT! N1 = 50581552

... (can set up four phone numbers)

3. Set ta long distance

AT! A0 = 3 at! A1 = 3 at! B0 = 3 at! B1 = 3

4. Software upgrade to TA using the downloaded TA.bin file

AT **

Firmware Download (Y, Y / N, N) Type Y Are You Sure (Y, Y / N, N) Type Y Clearing! Please Wait ... Wait until the following upload prompt message Start X-MODEM UPLOAD FUNCTION (start x -Modem protocol upload function)

Then, the transmitted file under the transmissive of the Hyper Terminal toolbar, in the dialog box, the file name is taken, the protocol is selected, and the TA will be restarted after the send is complete.

note! The software upgrade should be very careful, because the EPROM of TA has been removed, and new information is required. If it is not interrupted, it will cause Ta paralysis. If this happens, turn off the power of the TA and open the DIR jumper on the back of the TA to dial 3, 4 to ON. Then press the DATA button on the TA to turn on the TA power. At this time, the super terminal window will appear:

FIRMWARE DOWNLOAD (Y, Y / N, N) Type Y, you can re-upgrade.

5. Set the dynamic allocation bandwidth (BOD *) function of TA

AT! P1 = 0 (turn off the BOD function)

AT! P1 = 1 (open BOD function, default P2 = 48 p3 = 0 p4 = 20 p5 = 20)

AT! P2 = N (n = 0-127 unit kps) AT! P3 = N (n = 0-255 unit 10 seconds)

(When the flow rate of mlppp * exceeds P2, the maintenance time exceeds the time set to P3, automatically adds the second B channel)

AT! P4 = n (n = 0-127 unit kps) AT! P5 = N (n = 0-255 unit 10 seconds)

(When the flow rate of MLPP is lower than the value set by P4, the second B channel is automatically released when the time is set, and the time set below P5 is automatically released.

Note: = Enter

Note: BOD - dispense bandwidth on demand. That is, BANDWIDTH-ON-DEMAND, that is, can be automatically added or disconnected from network requirements. He can automatically detect the use of network bandwidth, when the user reads the downloaded HomePage, or when a small amount of data is exchanged, automatically disconnect the second B channel, when the user uses the maximum bandwidth, such as downloading a larger file, It automatically connects the second B channel. MLPP - Multi-link PPP. Bind two ISDN 64kbps B channels. Provide a 128kps connection channel.
