Systems, methods, and computer program embodiments are disclosed for detecting software components in a software codebase. In an embodiment, a source file containing source code may be received, and a code signature may be generated for the source file based on a determined structure of the source code. The generated code signature may then be compared to signatures stored in a reference database to identify matching software files. In an embodiment, the reference database may store a plurality of code signatures corresponding to software files. A list of the identified software files may be created and presented to a user.

Identifying software components in a software codebase

Systems, methods, and computer program embodiments are disclosed for detecting third party software components in a software codebase. In an embodiment, a source file containing source code may be received at a server, and a code signature may be generated for the source file based on a determined structure of the source code. The generated code signature may then be compared to signatures stored in a reference database to identify matching third party software files. In an embodiment, the reference database may store a plurality of code signatures corresponding to third party software files. A list of the identified third party software files may be created and presented to a user.

In a multi-service wireless, or wired, integrated services digital network having an analog loop driven by an analog loop adapter, the type-of-call information (i.e., voice, data, or fax) in a call setup message is used at the analog loop adapter to generate a call-type signal. A switch is interposed between the analog loop and each piece of terminal equipment on the loop. Each switch responds to the call-type signal lo adjust the switch setting so that terminal equipment attached to the switch which does not match the call-type does not receive the ensuing ringing signal.

Call switching system based on type of call

A system for providing fixed wireless access to standard telephony device is disclosed. A subscriber unit comprising a telephony interface for connecting to a standard telephony device, and a transceiver for establishing a communication link with a wireless network is used for providing telephony service to standard telephony device. Dual tone multiple frequency (DTMF) tones produced by said standard telephony device are sent to the wireless network, either directly or indirectly in the form of digit messages corresponding to the dialed digits, after a call set up message is sent. The subscriber unit sends a special set up message which identifies the subscriber unit as a terminal which sends digits on a digit by digit basis. A wireless network component (e.g. an MSC) is configured to identify such a set up message and upon receiving such a set up message collects and analyses digits sent by a subscriber unit on a digit by digit basis in order to provide a service feature or to connect a call.

System and method for interfacing a standard telephony device to a

The call set-up technique of this invention is characterized by the use of channel information from both base station and subscriber terminal in determining the radio traffic channel upon which to set-up a new call. Communication between the base station and subscriber terminal is carried out on a signalling channel until the traffic channel is chosen. Calls are set-up so that they proceed on the radio channel which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal. The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service. This subset is comprised of those channels having little interference, as measured by the base station, and which, additionally, are not reserved exclusively for stationary, fixed-allocation services in the geographic location of the base station. The call set-up technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal. The technique also facilitates sharing of the radio spectrum with stationary, fixed-allocation services because there is no need to program each subscriber terminal to avoid the spectrum allocated to the fixed service.

A wireless telephony system comprising a base station and at least one portable device. The base station employs a ratio frequency (RF) receiver and an optical transmitter. The portable device employs an optical receiver and an RF transmitter.

Hybrid telephony communication system

A cellular mobile radio communication (e.g. telephone) system (hereinafter referred to as a private cellular system, PCS) that does not have the constraint of being a well defined, pre-planned system. The present invention differs from previous systems largely by the fact that it does not have to be well planned in advance. A user can simply install a base station virtually wherever he desires. Each base station is 'intelligent' and produces a dynamic allocation. This of course means that if one were to install such a system, for example in an office building, no studies would be required. One would simply install a series of base stations.
