Abstract: A system and method for identifying and analyzing active channels in an asynchronous transfer mode (ATM) network. The system and method open a plurality of ATM network channels during a time period; automatically monitor each of the plurality of open channels to identify any active channels from among the open channels; and automatically identify the type of traffic transmitted on the open channels. By systematically identifying the active channels in the ATM network, the ATM network analysis device can further analyze the traffic on the active channels. The present invention includes at least three functions: network data detection and capture, active channel determination, and ATM Application Layer (AAL) service type categorization. A network data detector and identifier (DDI) performs the functions of network data detection and capture. The DDI connects to an ATM network and captures, copies, and repeats cells transmitted on the network and copies cells of interest to the DDI for further analysis.

Abstract: Disclosed is an intercept system for integrating the personalized services of switchboard attendants associated with on-premises PBX switching systems, with the capabilities of the intercept system for allowing calling parties the opportunity to complete their own calls to the on-premise switching systems when the telephone extension numbers of the called parties are known to the calling parties. Depending on the mode of system operation selected, the intercept system either presents all incoming calls directly to the switchboard attendants, or intercepts all incoming calls and presents the caller the opportunity to complete the call, or a combination in which incoming calls are first offered to the switchboard attendants for assistance and then after a time wherein attendant assistance is not gained, the call is intercepted and the caller is given an opportunity to complete the call.

Abstract: A system and method for identifying and analyzing active channels in an asynchronous transfer mode (ATM) network. The system and method monitor an ATM network signal channel to identify setup, connect, and release messages which permit identification of active switched virtual circuits and the service type used for that active virtual circuit's traffic. The system and method also possess the simultaneous ability to open a plurality of ATM network channels during a time period; to automatically monitor each of the plurality of open channels to identify any active channels from among the open channels; and to automatically identify the type of traffic transmitted on the open channels. By systematically identifying the active channels in the ATM network, the ATM network analysis device can further analyze the traffic on the active channels.

Abstract: Call processing apparatus for queuing calling parties waiting to be connected to a service position, and for calculating queue position data or wait time data and transmitting the queue data to the calling parties. The queued calling parties can also reach alternate destinations by inputting digit information for routing queued calling parties to such destinations.

Abstract: Apparatus for recognizing a telephone call supervision signal by comparing its frequency and cadence to the frequency and cadence of a previously learned call supervision signal is provided as part of call completion equipment (10). Call progress tone detector (50) receives a call supervision signal and responds by outputting frequency parametric signals which indicate whether predetermined standard frequencies are present in the received signal. Microprocessor (74) determines the cadence of the received call supervision signal and outputs a corresonding cadence parametric signal. If it is beneficial to learn the received call supervision signal, the frequency and cadence parameters are stored in memory (78). Recognition circuits can then recognize a subsequent telephone call supervision signal by comparing its frequency and cadence parameters to the frequency and cadence parameters stored in memory (78) for at least one learned signal.

Abstract: A call processor (32) for intercepting incoming calls to a key telephone system (10) and returning a message to a calling party. A digital message storage unit (48) stores messages associating called parties with respective pseudo-telephone numbers so the calling party can input information identifying a desired called party. A CPU (50) of the call processor (32) references a look-up table (52) with the pseudo-telephone number input by the calling party to select and transmit a message via an intercom line (36) to the key telephone system (10). The message carried by the intercom line (36) broadcasts a message relating to the identity of the called party as well as the line to utilize.

Abstract: Call completion equipment (10) is disclosed for use with a switching system (14) for assisting callers to complete telephone calls thereto. If a primary destination telephone set (16) is busy or does not answer, a message is transmitted from a message storage unit (54) to the calling party. The message relates to the selection by the caller of secondary destinations including a switchboard attendent 18, an alternate destination telephone set, a camp-on option or voice messaging facilities. A processor complex (72) processes the digits dialed by the caller in response to the message, using various look-up tables (85-87), and transfers corresponding information to the switching system (14). The switching system (14) completes the call to the secondary destination according to the information. The invention (10) provides automatic camp-on features (87) with regard to predefined telephone sets of the switching system (14).

Abstract: An improvement is disclosed for telecommunication PCM time division multiplex switching systems of the type having voice access ports, each with a voice path and a signalling path, and having PCM signalling and voice transmit buses to carry information to a switching network. From the network, PCM voice receive buses carry switched voice information to be demultiplexed, converted to analog form and connected to the voice port. A signalling bus carries information from the switching network to registers. The system is improved to enable it to switch data as well as voice information. A data port is provided to accompany each voice port, and the improved system includes means for multiplexing input data at the port and inserting it on the signalling transmit bus once the signalling portion of a call is completed. A receive data bus connects the signalling receive bus to means for demultiplexing data and presenting it to receive data ports.

Abstract: A serial data interface circuit for converting serial digital information having one transmission rate into corresponding digital information of another transmission rate. Such an interface circuit provides a serial data receive section clocked at an incoming data rate and a serial data transmit section clocked at a desired transmission rate. Interposed between the sections is buffer means for asynchronously transferring data information from the receive section to the transmit section whereby a different receive and transmit rate are accommodated.

Abstract: A digital conferencing arrangement for use in a digital telecommunications switching system. Digital coded signals representative of sampled analog signals are compared and the results of the comparison noted to identify the present speaker in the conference. A comparison result indicating a proposed new speaker initiates a delay interval during which subsequent samples are compared to assure that the proposed new speaker indeed has the largest analog signal during the delay window. Upon verification of the proposed new speaker, the control of the conference circuit is transferred to him.
