The autopatch features on the SHARC-1 Repeater are completely controlled by a Commodore 64 computer. The Commodore 64 is a power little computer that will out perform any commercial repeater controller out there on the market. Limitations of commercial controllers include: limited memory, limited input/output ports, and a limited macro set for generating unique commands. One of the biggest disadvantages of using a commercial controller is that if it should break, you're at the mercy of it's manufacturer, while it's sitting on a technician's bench. It's probably cheaper to buy a new one than having it repaired. Commodore 64's are great because they're inexpensive (going for $25 and under at hamfests), easy to program, and it's uses are only limited by your imagination. Since it's introduction to the market in 1981, the Commodore 64 is still a very popular computer, and will be around and supported for years to come. |
Mode #1 - Basic Access Basic Access is offered to those that want autopatch capability but are generally interested in placing phone calls within the general area that they reside or work. Basic Access provides over 27 toll free exchanges surrounding the 221 calling area. Basic users are provided with an autopatch access code that prohibits the use of placing calls outside the specified calling area (toll restrictor). Basic users enter in the desired telephone number which in turn is processed and redialed by the controller. Basic users are also offered the choice of selecting a personal access code (speed dial) that can be used to auto-dial a number of their choice. Basic Access calls are restricted to 3 minutes in length. If the conversation continues past this point, the controller will terminate the call (timeout), and reset the system.
Mode #2 - Control Operator Access
Mode #3 - Reverse Access
