The application relates to high-quality audio transmission through a network, e.g. using a higher level audio protocol such as Voice over IP. Normal telephone conversations which are provided by the telephone network experience a low audio bandwidth of approximately 3.1 kHz, This problem is solved in that an audio device (1110,1120,1130) is coupled to the network (1300) by a gateway (1210,1220). The gateway negotiates with the network in order to select a particular bandwidth from the network. Subsequently, an audio codec appropriate for the selected audio bandwidth is selected. Audio codecs comprise variable and constant bit rate codecs and codecs corresponding to standards such as MPEG, Dolby, THX, APT etc.

In a method of managing network addresses for private voice communications, a first request is received from a requesting agent for a connection having a quality of service parameter, a second request for one of a plurality of network addresses based on the quality of service parameter is received, a network address in accordance with the second request is received, and the network address is sent to the requesting agent to establish the connection in accordance with the first request. A media access controller (MAC) is provided having a plurality of MAC addresses, and a requesting agent for sending a first request for a network address is connected to the MAC. A driver module is connected to the MAC and the requesting agent to receive the first request and determine whether the first request is for one of a multimedia connection or data connection. The driver module instructs the MAC to send a second request for a first network address using a first MAC address if the first request is for a multimedia connection, and to send a second request for a second network address using a second MAC address if the first request is for a data connection.

A new architecture capable of utilizing the existing twisted pair interface between the customer services equipment and the local office is used to provide a vast array of new services to customers. Using an intelligent services director (ISD) at the customer services equipment and a facilities management platform (FMP) at the local office, new services such as simultaneous, multiple calls (voice analog or digital), facsimile, Internet traffic and other data can be transmitted over the existing single twisted pair using xDSL transmission schemes. New services such as the implementation of videophone, utility metering, broadcasting, multicasting and other services can be implemented with this architecture. The overall architecture of the system employs fault tolerant, transparent interaction of components and services. The new architecture supports a variety of standards for each level in the OSI layers and TCP/IP layers. The FMP connects electronically or optically to the PSTN, Internet backbone, or private Intranet.

A highly reliable early warning system that can provide efficient detection of railway activity and early warning of dangerous railway conditions to train operators and to central dispatch control offices. The warning system has an acoustic sensor circuit coupled to the railway for detecting sound waves resulting from physical vibrations thereon, an acoustic analyzer unit for analyzing the sound waves detected on the railway to identify any suspect conditions thereon and to generate an alarm if such a suspect condition is identified, and an acoustic signal processing unit for storing detected sound waves in a sound file for quick retrieval and analysis. The alarm signal may be transmitted over any communications system to the central control office and to trains traveling on the dangerous track. The stored sound files may be locally retrieved or downloaded to a remote location over a cellular system, thus enabling the analysis of the actual sound generated by the dangerous condition to determine the cause therefore.

A personal communicator is disclosed which comprises an antenna, means for receiving a number assignment module via said antenna, and means for storing the number assignment module so as to customize and/or singularize the personal communicator. Such a personal communicator can thereby be programmed remotely by a cellular service provider without having an authorized agent manually program the personal communicator.

The present invention provides an efficient solution for regulating the amount of advertisement directed towards a particular consumer. In its broadest sense, the present invention gives advertisers the ability to expose consumers to advertisements for a specified period, as well as collect information on the exposure that a customer has had with an advertisement or group of advertisements before a purchase is made. Based on this information, advertisers can make strategic decisions on how to more efficiently market their products. Additionally, the present invention eliminates the wastefulness associated with advertising to a non-existent audience and audiences that have already been continuously exposed to previously similar advertisements. The advertisements will only be shown when someone is present to view them. As a result, the manner in which advertisements are presented to consumers can be monitored and more efficiently managed.

A cordless telephone network for wirelessly linking with a wireless phone. The cordless telephone network may include a plurality of wireless base stations, the base stations preferrably being disposed at customer premises such as private residences and/or businesses. A wireless phone linked to the cordless telephone network may roam between the wireless base stations and/or between the cordless telephone network and any other wireless network such as a conventional cellular phone network.
