Micro Seven model ST10-2, Automatic Telephone Line Tester, provides automatic testing of maximum twenty telephone lines by dialing each line for testing whether call to the line is answered or not. Test failure is indicated on ERROR LED and warning sound is generated at internal speaker. Failed line is reported to serial interface in PC. PC-assisted testing mode displays test result and a text file is generated as a disk file. Telephone numbers are stored in non-volatile memory in ST10-2, and test will start by itself when there is power failure. Internal audio monitor is provided to hear the test. The standard accessories of ST10-2include AC/DC adapter, serial port cable, control software, and operator’s manual. A carrying case, car-batttery adapter, or 230V AC/DC adapter is extra. The control software for programming ST10-2 and PC-assisted test is provided as a standard accessory.

ASCII commands without using provided control software:
number entry: W44 (n1) (n2) for setting up line number, then enter
D<telephone number-maximum fifteen digits><CR> to program a
for example W4400<CR>D5035551212<CR> for dialing 5035551212 for line 1. Note <CR> is a carriage return. It is stored in EEROM (non-volatile memory) in AP15.
Polling interval entry: M(n1) (n2) (data)<CR>
Alarm message entry: S<fifteen digit long alarm
Note: ST10-2 prepares check sums, so do not enter sixteen digits. When sixteen digit-long alarm message including check sum is entered, checksum, which is prepared by ST10-2, will become a wrong one. It is stored in EEROM (non-volatile memory).
Start alarm reporting process by dialing the telephone number, receive handshake tones, transmit alarm messages, receive kiss-off tones and hang up the line. A carriage return is not needed.
