    • Solving the aging problem of crystal oscillators by doing field recalibration. The solution is to utilize an accurate external reference signal to determine when the frequency of the digital temperature compensated crystal oscillator (DTCXO) has drifted from the reference signal in excess of a specification. When this occurs, the DTCXO has used its internal compensation values to correct its output hence the difference between the external reference signal and the frequency of the DTCXO in excess of the specification is due to aging. A new compensation value for the present temperature is calculated using the reference signal. Using the well known fact that the temperature aging uniformly shifts the frequency over the temperature range, a controller utilizes the difference between the new compensation value and the stored compensation value for the present temperature to shift the entire set of compensation values to compensate for the aging effect.
    • 通过进行现场重新校准来解决晶体振荡器的老化问题。 解决方案是利用精确的外部参考信号来确定数字温度补偿晶体振荡器(DTCXO)的频率何时从超过规格的参考信号漂移。 当这种情况发生时,DTCXO使用其内部补偿值来校正其输出,因此外部参考信号与DTCXO的频率之间的差异超出规格是由于老化。 使用参考信号计算当前温度的新的补偿值。 使用众所周知的事实,即温度老化在温度范围内均匀地移动频率,控制器利用新的补偿值和存储的补偿值之间的差值来使当前温度偏移整个补偿值组以补偿老化 影响。

    • A communications switching system such as a PBX, central office switch and the like, responds to an incoming call to a called party by signaling a paging device as well as some other communications device having communications capability different from that of the paging device. In the disclosed embodiment, which pertains to a private branch exchange (PBX), this other communications device is one which provides two-way voice communications. Advantageously, the paging device may also be provided with the capability of signalling the communications system that the called party will shortly answer the call via a communications device possessing two-way voice communications. Upon receipt of this pager-transmitted signal, the communications system, if desired, can be provided with the ability to provide an announcement to the calling party of the called party's intent to answer the call. Once the called party reaches any voice communications device connected to the system, the incoming call is redirected to that device upon the called party providing a predetermined identification to the communications system.

    • Apparatus for and a method of inserting circuit switch information and packetized data into different time slots of a time division multiplexed bus. A memory having a location individual to each time slot is written with information specifying whether the time slot individual to each location is to serve circuit switch information or packet data. The readout of each memory location during the occurrence of it's associated time slot controllably effects the application of either the circuit switch information or the packet data to the bus. Packet data can be inserted into each time slot not currently being used by the circuit switch. A special information bit is inserted into each time slot to specify whether the remainder of the bits of the time slot represents circuit switch or packet information. The information bit is used by receiving apparatus to steer the bits of each time slot to either a receiving circuit switch or a receiving packet switch.
