Data generated at a telecommunications network switching node is selectively delivered to one or more data receiving device (e.g., data 'collection box') connected to the network, and command and control signaling is transmitted from the data receiving device to the switching node. This bi-directional communication is carried out in a manner compatible with voice grade lines. In an exemplary application, call identifying information, referred to in the TIA/EIA Standard as CDC (Call Data Channel) Messages, is delivered from an Intercept Access Point (IAP) switch that provides telephone service to a subject of an authorized surveillance order, to a law enforcement data collection box, utilizing Frequency Shift Keying (FSK) signals. Control signals are sent from the data collection box to the IAP switch utilizing Dual Tone Multi-Frequency (DTMF) signaling. The state of the art is advanced, and a contribution is made to law enforcement and other fields, as the invention allows replacement of costly and lengthily provisioned data delivery circuits, such as ISDN lines or private digital data circuits, with widely available and less expensive voice-band data delivery equipment.

Controllable telecommunications switch reporting compatible with voice grade lines

A method and apparatus for controlling administration of Automatic Call Distributor (ACD) queues of an ACD or network of ACDs by a caller, and of communicating data to an ACD Agent. The caller receives information concerning the status of queues in one or a plurality of ACDs. If the caller wishes to communicate with a particular Agent, wait time for that Agent is provided to the caller. The caller can select a particular Agent, and will be connected when that Agent becomes available subject to other restrictions of the ACD queue. The caller can prepare information for transmission to an answering Agent while the caller waits. Advantageously, the caller can control which Agent or which sub-group of Agents should respond to his/her call, taking into account the different waiting times associated with a particular Agent or the first available Agent when the caller reaches the top of the queue.

Enhanced end user automatic call distributor control

Enhanced subscriber line monitoring is provided for telephone calls in a telecommunications network. A telecommunications switch ( ) is coupled to adjunct processor ( ). Subscriber lines ( ) terminated by the telecommunications switch are selectively monitored. Call identifying information and call content received by the telecommunications switch is forwarded to the adjunct processor for storage and analysis. The analysis includes determining the class of call content, e.g., voice or data. Call content is used to determine quality associated with a call. The call analysis is used for network management, new service development, long term usage forecasting, service differentiation for billing and targeted marketing opportunities.

Enhanced subscriber line call monitoring

A method and apparatus for conserving Communications Content Channels between a serving switching system and a Law Enforcement Agency premises. After a connection has been established between the serving switch and the Law Enforcement Agency premises using one of the Communications Content Channels, an Agent can transmit an indication that the communication is no-longer of interest; in response to receipt of that indication, the switch disconnects the call from the Communications Content Channel. Advantageously, this arrangement can reduce the number of Communications Content Channels required to monitor a particular target customer, and can overcome arrangements for flooding the Communications Content Channels with non-significant messages.

Utilization of communication channels between a central office switch and a law enforcement agency

A method and apparatus for communicating between Customer Premises Equipment, (CPE) alarm sensing devices, and alarm monitoring stations. The sensing devices communicate with an end office switch by transmitting a message, such as a string of Dual-Tone Multi-Frequency, (DTMF) digits to that switch. At the switch, the message is processed and a determination is made which of a plurality of alarm monitoring stations should receive the alarm indication. One or more data packets are sent to the selected alarm monitoring stations with the packets identifying the source of the alarm indication, and the type of alarm indication. Advantageously, the packetized communication between the end office switch and the alarm monitoring system allows a high volume of alarm indications to be sent to an alarm monitoring station, because individual telephone connections are not required for each such alarm message.
