    Abstract: A flexible service access code (FLEX SAC) permits originating callers to dial up to a fifteen-digit extension in place of a traditional service access code (SAC), such as for example a "700", "800" and "900" extension followed by a seven-digit extension. In addition to providing the originating caller, the destination caller, and the long distance carrier greater flexibility in the digits dialed for a SAC call, FLEX SAC permits routing on private trunks and remote access trunks, as well as the shared access trunks conventionally used for SAC calls. If the switch supports FLEX SAC calls, a FLEX SAC table (pertaining to the originating trunk group over which the call was routed) is parsed to find the called number. If the called number is found in the FLEX SAC table, additional fields indicating ANI screening, OLI screening, external routing, and the transaction group are parsed in the relevant FLEX SAC table.

    Abstract translation: 灵活的服务访问代码（FLEX SAC）允许发起呼叫者拨打一个十五位数的分机来代替传统的服务访问码（SAC），例如“700”，“800”和“900”分机 其次是七位数的延伸。 FLEX SAC除了提供始发呼叫者，目的主叫方和长途运营商在SAC呼叫拨打的数字中更大的灵活性外，还允许在专用中继线和远程接入中继线上进行路由，以及常规用于 SAC电话。 如果交换机支持FLEX SAC呼叫，则会解析一个FLEX SAC表（属于发起呼叫路由的始发中继组），以查找被叫号码。 如果在FLEX SAC表中找到被叫号码，则在相关的FLEX SAC表中解析附加表示ANI筛选，OLI筛选，外部路由和事务组的字段。

    Abstract: If an access code specifying an interexchange carrier (IXC) (30) is entered by a caller (11, 12), the switch of the LEC (21, 22) routing such a call to the specified IXC (30) is arranged to transmit to the IXC (30) an indication that an access code was entered. The indication may be transmitted as a signaling system 7 (SS7) message, or a portion thereof. The LEC (20) may also provide an indication that the carrier whose access code was entered was not the IXC carrier (30) to which the calling telephone line was PIC'd. Advantageously, using the transmitted indication, an IXC (30) can determine the number of instances in a predetermined time period that calls were placed using its access code, thereby verifying the effectiveness of its advertisements for use of the access code.

    Abstract translation: 如果由呼叫者（11,12）输入指定了交换机（IXC）（30）的接入码，则将该呼叫路由到指定的IXC（30）的LEC（21,22）的交换机设置成发送 到IXC（30）表示输入了访问代码。 该指示可以作为信令系统7（SS7）消息或其一部分被发送。 LEC（20）还可以提供其输入访问代码的运营商不是呼叫电话线路被映射到的IXC运营商（30）的指示。 有利地，使用所发送的指示，IXC（30）可以使用其访问代码来确定在呼叫被放置的预定时间段中的实例的数量，从而验证其广告对于访问代码的使用的有效性。

    Abstract: A system and method to detect a call trigger during a call without requiring a service platform to remain connected to the call. A first communication device (106) transmits a call having call signaling and user communications. A signaling processor (112) receives the call signaling from the first communication device and selects a connection to a second communication device (108). An interworking unit (114) receives the user communications from the first communication device and converts the user communications from a time division multiplex format to asynchronous transfer mode cells that identify a selected connection to the second communication device. The interworking unit detects a call trigger in the user communications. The interworking unit transmits call trigger data to the signaling processor. The signaling processor processes the call trigger data and, upon validating the call trigger, instructs the interworking unit to transport the user communications to asynchronous transfer mode cells that identify the selected connection to the thrid communication device (110) and transports the user communications to the third communication device.

    Abstract: An agent speech detector system (100) comprises an interface circuit (104), a supervisor computer system (105) and an agent unit (106). An agent unit (106) includes an input device (114) and an agent terminal (112) which detects whether an agent speaks during a telephone call routed to the agent by a telephonic switch (102). An interface circuit (104) may interconnect the agent terminal (112) and the telephonic switch (102). An agent console (107) may be interposed between the interface circuit (104) and the telephonic switch (102). The telephonic switch (102), preferably an automatic call distributor (ACD), routes telephone calls generated by callers at telephonic units (108) and transmitted over a telephonic network (110). The headset provides audio communications between the agent and the caller through the telephonic switch (102). The headset typically includes a microphone (115) and one or more speakers (116).

    Abstract: DC level control for an electronic telephone line card which filters the DC component from the input audio signal, determines the gain setting of the transmit path, develops a DC adjust voltage opposite to that of the DC shift component and subtracts the DC adjust voltage to the input voltage to cancel the DC shift component. A quantized, discontinuous feedback path is implemented to respond only to DC shifts so the AC operation remains substantially unaffected. Such discontinuous feedback eliminates stability and impedance matching problems introduced with continuous feedback solutions. A DC control circuit according to the present invention includes a low pass filter for detecting DC shifts, a quantizer for asserting an incremental signal, a threshold detector for activating adjustment functions, and an accumulator for developing the DC adjust voltage by incremental steps. A long term low pass filter and reset circuit resets the accumulator to cancel residual DC adjust voltages which might otherwise reduce the dynamic range of the telephone line transmit path.

    Abstract: A telephone subscriber (20A) to a long distance telecommunication system is permitted, in accordance with this invention, to enter changes in real time utilizing a conventional Touch-tone telephone to control the routing or handling of incoming calls. A real-time update network control point (RTU NCP) (62) is accessed by subscribers and contains input steps, which controls the entry of changes by the subscriber. Upon the completion of the entry by the subscriber of the desired changes in RTU NCP, the latter causes the changes to be transmitted to the subscriber's NCP (SUB NCP) (74a), which controls the processing of incoming calls to a directory number associated with the subscriber based on subscriber data stored in the SUB NCP. The SUB NCP data corresponding to the subscriber is modified in accordance with the changes, so that incoming calls will be handled in accordance with the changed subscriber data.
