摘要： A microprocessor/based telephone/facsimile controller which automatically gives priority to incoming messages. The ring voltage of an incoming message causes the microprocessor to close and latch the line between the telephone and the facsimile. When transmission is completed, the line is dropped and this condition is sensed causing the latch relay to open to prevent the facsimile from transmitting, no data being logged for incoming facsimile transmissions. Only a valid input code permits the coupling of the facsimile to the telephone line also initiating a timer. A broadcast mode latches the telephone line to permit delayed calls and multiple facsimile transmissions, each allocated to the user code which established the broadcast mode. A default time is utilized to accommodate the redial and use of the line for non-facsimile telephone transmission.
摘要翻译：一种基于微处理器的电话/传真控制器，其自动优先接收传入的消息。传入消息的环电压使微处理器关闭并锁定电话和传真之间的线路。当传输完成时，线路被丢弃，并且感测到该状态导致锁存器继电器打开以防止传真机传送，没有数据被记录进入传真传输。只有有效的输入代码允许传真机与电话线路的耦合，也启动定时器。广播模式锁住电话线路以允许延迟呼叫和多个传真传输，每个传真传输分配给建立广播模式的用户代码。使用默认时间来适应非传真电话传输线的重拨和使用。

摘要： Method and apparatus for operating a copier-duplicator which initially produces a master and thereafter produces copies from the master. The copier-duplicator is enabled upon receipt of a valid access code to begin producing the master and copies thereof. Counts of the number of masters and copies are accumulated. The copy count is compared against a minimum amount and each time a new master is made and if the number of copies produced is less than said minimum, a violation count is stored together with its associated access code. If the copier-duplicator is in a lock-out mode, access is denied to the access code having a violation. If in a flag mode, access to the machine is permitted even if a violation code is present. However, there is a capability of displaying all of those access codes having a violation associated therewith. It is further possible to prevent access to the copier-duplicator in the event that the number of copies or masters exceeds a maximum permissible amount.
