  • Patent number: 6463269
    Abstract: A product and system is disclosed for intelligently controlling the number of amplifier modules that are active in a linear amplification system. By exercising such control, the system can avoid using unnecessary power. The invention monitors the system and gathers information from signals associated with the system, particularly information concerning signal power. A control functionality evaluates the gathered information to decide how many modules are necessary to sufficiently operate the amplification system or to decide if it has been commanded to perform certain functions. Once this decision is made, the control functionality communicates control signals to the power amplification modules to activate the needed or desired number of modules and deactivate the unneeded or undesired number of modules. Likewise, the control functionality configures the splitter and the combiner according to the number of needed or desired amplifier modules. This gathering, evaluation, and control is conducted continuously.

  • Patent number: 6356756
    Abstract: A method and system for routing calls to a wireless platform uses local number portability searches to achieve advanced intelligent network capabilities. The method and system of the present invention “ports” wireless subscriber numbers to a number for a platform providing a specific service. When a caller dials the subscriber's wireless number, a switch determines whether the number is portable. Since the number has been ported, the switch launches a query to a local number portability service control point to obtain additional routing instructions. The service control point accesses a local number portability database to determine the proper routing number. The new routing number allows calls to be routed to a service platform in the wireless network. The service control point transfers the routing number to the switch which then translates the routing number to a directory number for the platform. The call is then routed to the platform.

  • Patent number: 6324269
    Abstract: A method and system for billing remote calls includes the provisioning of an active terminating attempt trigger on a subscriber's primary line. To make a long-distance call from a remote location, the subscriber calls a service control node and provide a destination calling line number and the subscriber's primary line number (e.g., home telephone number). The SCN assembles the data into a string and includes a feature access code. This string is transmitted to a switch that recognizes the feature access code and transmits a message to a service control point. The service control point also recognizes the feature access code and reassembles the message into a call structure containing the primary line number, the destination line number, and a code indicating that the message should be reassembled. This message is transmitted back to the switch which then routes the call to the primary line switch where the trigger is encountered.

  • Patent number: 6044265
    Abstract: A method for programming a cellular set over a control channel may be used to update data stored within a cellular set by having the cellular set search the control channel for data updates that are broadcast over the control channel upon command of a controller coupled to the wireless system. In one embodiment, the method updates a carrier list of system identification numbers ("SIDs"). A cellular set searches the control channel for a unique identifier that is followed by the current carrier list number. The cellular set compares the current carrier list number with a stored carrier list number. If the carrier list numbers do not match, the cellular set stores the current carrier list number in memory and enters an acquisition mode in which it continuously monitors the control channel for updated data, possibly in the form of SIDs to add or remove from the list. The cellular set is programmed to recognize the updated data and retrieve it into memory.

  • Patent number: 5974139
    Abstract: A line isolation device (LID) for use in an ADSL system provides a single low pass filter that filters out the higher band ADSL signals for all of the Plain Old Telephone Services (POTS) terminal devices within a customer's premises. The LID may be easily added to an existing ADSL system by routing signals from a customer bridge through the LID. The LID has a low pass filter for removing the ADSL signals and also has a bypass path for carrying unfiltered ADSL and POTS signals to an ADSL transceiver unit. The filtered POTS signals are supplied back to the customer bridge and to binding posts on the customer bridge where all POTS terminal devices receive their POTS signals. The re-routing of the signals within the NID through the LID can be easily accomplished by disconnecting a testing jack on the customer bridge and routing the signals through the LID. Alternatively, the customer bridge may be completely removed from the NID and replaced with a customer bridge having an integral low pass filter.

  • Patent number: 5937168
    Abstract: After an origination module (OM) receives information, a packet is transmitted to a routing architecture (RA) for routing to a destination module (DM) designated by the router packet. The RA interprets the router packet and adaptively routes the router packet to the DM so that the router packet is quickly processed by the DM. If the DM's queue is empty and the DM is not processing any other packets, the RA places the router packet in the queue and the DM reads its queue to process the router packet. If there is another router packet being processed by the DM, the RA adapts by placing the router packet in the queue. Once processing of the other router packet is complete, the DM processes the router packet in the queue. If there is already another router packet pending within the DM's queue, the RA adapts by creating another DM in memory to process the router packet.
