F R E E U P Y O U R P H O N E L I N E S ! JEC TECH is introducing a new automated Telephone line Simulator which will allow you to tie two modems together locally without using phone lines. THE LINKER ($149.95) was specifically designed to link modems automatically making testing as easy as 1, 2, 3. (1) First, plug the send modem into the RJ-11 jack you've designated as the "send" jack and plug the modem under test into the "receive" jack. (2) Next, select the AUTOMATIC mode and either 20 or 60 Hertz ringing. The 20 Hertz is probably the best choice. (3) And finally, give the send modem the ATDTXXXXX command to dial out. Use any number you like since it's not going anywhere. Once the send modem goes off hook, dialtone is automatically applied to the send modem and ringing is automatically applied to the receive modem. When the receive modem answers, it swaps tones with the send unit and connects. Simply proceed just as if you had made the connection over real phone lines. By the way, THE LINKER works just as well with voice dial up devices (like voice mail systems or call directors), fax machines, answering machines, and full featured phones. In fact, you can test or demonstrate just about any device normally connected to the switched network! What follows is a crude attempt to show you the front panel layout of THE LINKER. It's not great, but it's the best I can do using ASCII. ________________________________________________ I I I _#1__ THE __#1__ I I RJ11 LINKER RJ11 I I JK JK I I ----- ----- I I A B I I A=SEND B=RECV I I <- #2 -> I I B=SEND A=RECV I I I I PUSH FOR AUTO LINE 20 HZ PUSH FOR I I #3 #4 #5 #6 #7 I I DIALTONE MAN STATUS 60 HZ RINGING I I------------------------------------------------I #1 - Standard RJ-11 jack to plug any telephone interconnected device into. It could be a telephone, answering machine, fax machine, modem or any dialup device using a modem as the interface. #2 - Standard DPDT toggle switch to reverse the function of the A and B RJ-11 jacks. When the toggle is thrown to the left, the A jack is the send and the B jack is the receive. With the switch thrown to the right, the B jack is the send and the A jack is the receive. #3 - Push button switch to activate dialtone. This push button switch works in both the AUTOMATIC and MANUAL mode. #4 - Standard SPST toggles to select either AUTOMATIC or MANUAL generation of dialtone and ringing. In the AUTOMATIC mode, as soon as the device plugged into the RJ-11 jack which you have designated to be the send jack goes off hook, dialtone is automatically applied to the send device and ringing is automatically applied to the device plugged into the receive jack. This feature is very handy when linking modems and fax machines. In the MANUAL mode, the two push button switches (#3 & #7) are used to generate dialtone and ringing. #5 - LINE STATUS indicator. This is a T1-3/4 bi polar green/orange LED. With everything on hook, this indicator shows a high intensity green. When the device plugged into the send jack goes off hook, the color changes to orange. When the receive device goes off hook, the brightness dims but the color remains orange. The color becomes a bright orange during ringing and it flashes at the ringing rate. Note that 60 Hertz ringing will appear as a steady brightness because the LED cannot respond to this faster ringing frequency. #6 - Standard SPST toggle switch to select the desired ringing frequency. Either 20 or 60 Hertz can be selected. #7 - Push button switch to activate ringing. The actual ringing frequency is determined by the setting of switch #5. We have an eight (8) page catalog describing THE LINKER in more detail plus it has real pictures to give you a better idea of what it looks like. The catalog also describes our other products like THE PHONE HELPER ($89.95) and THE LOOPER 2 ($99.95) as well as two compact ring generator modules that would be easy to incorporate into any project needing on board ringing capability.
