Abstract: A system is described for analyzing and automatically recognizing content of packet streams intercepted over a communication link. The system comprises an interface and a packet stream analyzer. The interface is configured to receive packets over the communication link and assemble the received packets into one or more packet streams. The packet stream analyzer is configured to receive respective packet streams from said interface and analyze each packet stream to generate selected types of information regarding the packet stream. The packet stream analyzer comprises an analyzer module graph comprising a plurality of analyzer modules interconnected in a graph. Respective ones of the analyzer modules are configured to perform at least one analysis operation in connection with at least a portion of a packet stream provided thereto to determine the likelihood that the packet stream is of one of a plurality of predetermined types, and generate at least one selected type of information in relation thereto.

Abstract: A packet interception system intercepts message packets transmitted from a packet source or to a packet destination, and processes them so as to facilitate verification of the contents and the sequence with which the message packets are intercepted, and for storing the processed message packets for later use. The packet interception system generates for each intercepted message packets respective hash values based on the respective intercepted message packet and the hash value generated for the previously-intercepted message packet, or, for the first intercepted message packet, a value that is provided to identify the session. To verify a previously-stored intercepted message packet, the packet interception system, or another device, using the same hash algorithm, can process the sequence of stored intercepted message packets up to and including the intercepted message packet to be verified, to and compare the hash value generated to the previously-generated hash value for each of the message packets.

Abstract: In accordance with an adaptive dialing method, a dialer control module controls a modem to place a telephone call to a telephone line and efficiently classify the telephone line, that is, to determine whether a device connected to the telephone line is one or more of a plurality of types of devices, illustratively, a voice telephone, a fax machine or modem, or a data modem. In accordance with the method, the dialer control module can enable the modem to, in one call, determine whether the telephone line is connected to a voice telephone, on the one hand, or a fax machine or modem or a data modem, on the other hand.

Abstract: A telephone scan-dialing arrangement includes a listener module, at least one dialing control module and at least one dialing module, each dialing module being associated with a respective modem. The listener module receives a command to initiate a scan-dialing operation in connection with a profile that identifies, inter alia, telephone numbers to be dialed and operations to be performed during each call and telephone number selection criteria, and provides the identification of the profile to the dialing control module The dialing control module obtains from the profile a set of telephone numbers to be used during the scan-dialing operation and provides the obtained telephone numbers to respective ones of the dialer modules to be dialed for a call, along with information identifying operations to be performed during the call, as each dialer module finishes its previous call.

Abstract: A game apparatus comprising a game board having a playing field comprising a map, a plurality of terminals, a plurality of routes across the map, each route extending between a pair of terminals and divided into a plurality of playing spaces some of which bear instructional indicia; a plurality of cards from among which a player draws one or more cards bearing indicia instructing the player; a plurality of playing tokens (such as miniature trucks) for representing a player's location on the playing field; a die for randomly designating the number of playing spaces to be moved by a player along one of the routes during the player's turn; and imitation money for transactions calling for payment or receipt of money during the course of play. Advertising copy related to the trucking industry is displayed on the game board.
