摘要:
An apparatus is provided for forwarding communications automatically. The apparatus includes a processing element that receives data from a local connection point or a network element regarding the presence of a device at or near the local connection point or other location. The device is associated with a first communications terminal and transmits a signal that can be detected by the local connection point or the network element. Upon receiving the data, including an indication of the presence of the device, the apparatus may automatically forward communications from one or more communications terminals to a particular communications terminal, as specified by forwarding instructions. The forwarding instructions may be provided by a user ahead of time or included in the data received by the apparatus, and the instructions may be stored in a storage element of the apparatus. Systems, methods, and computer program products for forwarding communications automatically are also provided.

摘要:
A signaling mediation agent (SMA), facilitating communications among communication nodes by ensuring that signaling messages transmitted by the SMA have been modified so that they conform to the protocol variants used by the destination communication node. In one embodiment, the SMA also facilitates communications by ensuring that communication nodes on a private network are authenticated and authorized to receive various communication services, even if the communication nodes on the various networks use different communication protocols or variants of the same protocol.

A system subsidizes telephone calls over a network. The system includes a service provider 120 that establishes a telephone call between a calling party terminal 130 and a called party terminal 140 over the network 110. During the telephone call, the service provider causes at least one advertisement 312 to be displayed at the calling, or called party terminal. At any time during, or after, the telephone call, the service provider generates a bill based on a subsidized billing rate related to the display of the at least one advertisement.
摘要:
Apparatus for and method of communicating over a local area network is disclosed. Multiple nodes are connected by an optical fiber in a ring architecture. The cable supports multiple subcarrier multiplexed data communication channels for transmitting and receiving message data between the nodes and a control channel for partitioning nodal access to the individual data channels. Tokens are circulated on the control channel indicating the status of each data channel. A node desiring to send, acquires an open data channel by marking the corresponding control channel token to show that the selected data channel is no longer available, inserts the node destination address into the control channel token, and transmits data on the acquired data channel. A node recognizing its address in the control channel token's destination address field for a particular data channel tunes its receiver to accept data on that channel.
摘要:
Optical communication methods and apparatus are disclosed for transmitting two or more optical signals with different optical carrier frequencies on a single optical fiber with high spectral efficiency. Each optical carrier is typically modulated with multiple modulated subcarriers. In one embodiment, an optical phase modulator provides cancellation of second order intermodulation products in each optical signal, thereby permitting the optical carrier frequencies to be spaced by 2f.sub.max, where f.sub.max is the maximum modulation frequency. In another embodiment, a single sideband optical phase modulator provides cancellation of second order intermodulation products and one signal sideband, thereby permitting the optical carrier frequencies to be spaced by f.sub.max. Quadrature optical phase modulators for simultaneous transmission of two independent baseband digital data signals or two independent subcarrier multiplexed signals are disclosed.
摘要:
An optical waveguide for use in an optical communication system employing a broad spectral source. Mode coupling is present in the propagation of optical signals in the waveguide, and the parameters of the waveguide are such that pulse dispersion produced by the finite spectral width of the source is minimized by utilizing the mode coupling to substantially cause cancellation of dispersion which is linear with respect to waveguide length and which is caused by the mode independent material dispersion and by the mode dependent waveguide dispersion.
摘要:
Enhanced call management services to users receiving incoming calls on extensions on a private branch exchange (PBX) is provided by an application server configured to provide call management services to at least one of the users and a protocol proxy configured to receive call information from the PBX according to a protocol for establishing call sessions. The application server is further configured to receive the call information from the protocol proxy.
