Abstract: An interface (10) is disclosed for coupling a conventional pay station telephone (12) to a telephone switching system (16). The interface (10) provides supervision signal detection functions normally provided by a switching system, and thus can be connected thereto by a less costly business line (28). The interface includes processor controlled tone generators (72, 76) and detectors (73, 74, 81, 106, 108) for detecting tones and voltages transmitted by either the telephone (12) or the switching system (16). The interface (10) further includes a detector (106) and a procedure (FIG. 8) for providing an answer call indication. Coin collection or return is controlled by the interface (10) depending on the status of the call which is also determined by the interface (10).

Coin collection or return is controlled by the interface (10) depending on the status of the call which is also determined by the interface (10). Further, a fail-safe relay will disconnect the phone from the tip and ring lines in the event of station irregularities. If the fail-safe relay operates during a phone call, the connection is maintained until the end of the call by power fail call holding relays.

Abstract: A programmable telephone powered by a telephone line, and responsive to ringing signals for providing an automatic answer. A microprocessor in the telephone is powered by periodic signals during ringing intervals for executing instructions to count the number of ring cycles, and is placed in a sleep mode if such number does not exceed a predefined threshold. When the threshold number of rings occurs, the microprocessor places the telephone in a simulated off-hook condition for allowing programming of the memory thereof. The memory of the microprocessor is an EEPROM having a file allocation table with addresses pointing to an input dialing pattern table, an area code/exchange code table and to an output dialing pattern table. Multiple levels of user and software security codes are employed to provide a high degree of security to the programming of the telephone.

Abstract translation: 一种由电话线供电的可编程电话，并响应振铃信号以提供自动应答。 在振铃间隔期间，电话中的微处理器由周期性信号供电，用于执行指令以对循环次数进行计数，并且如果该数量不超过预定阈值，则其处于睡眠模式。 当出现阈值数量时，微处理器将电话机置于模拟摘机状态，以允许对其存储器进行编程。 微处理器的存储器是具有文件分配表的EEPROM，其中地址指向输入拨号模式表，区域码/交换码表和输出拨号模式表。 使用多级用户和软件安全码来为电话的编程提供高度的安全性。

Abstract: A telephone set for automatically accessing operator service facilities in response to a user initiating a long distance type of telephone call. The access of the operator services is automatic and transparent to the user. After the user dials the "1" or similar long distance designation, the area code and a seven-digit telephone number of the called party, the telephone set stores such information, and in response thereto outpulses a predefined telephone number of the operator services. The telephone set responds to a precision dial tone transmitted as an acknowledgment by the operator services, and outpulses first an internally stored telephone set identificaiton number, followed by the area code and seven-digit number input by the calling party. Such outpulsed information appears on a video terminal of the operator services, whereupon the calling party and an operator can discuss billing of the telephone call, as well as completion thereof to the called party.

Abstract translation: 用于响应于用户发起长途电话呼叫而自动接入运营商服务设施的电话机。 操作员服务的访问对于用户是自动且透明的。 在用户拨打“1”或类似的长途指定之后，该区号和被叫方的七位电话号码，电话机存储这样的信息，并且响应于此，输出了预定的电话号码的运营商业务。 电话机响应作为运营商业务的确认发送的精确拨号音，并且首先推出内部存储的电话机标识号，然后由主叫方输入区号和七位数字。 这样的突出信息出现在运营商服务的视频终端上，主叫方和运营商可以讨论电话呼叫的计费，以及对被叫方的完成。
