摘要:
Example methods and apparatus to implement communication networks using electrically conductive and optical communication media are disclosed. An example method involves receiving first communication information via a conductive communication medium and second communication information via a first optical fiber communication medium. The first communication information and the second communication information are multiplexed to form a multiplexed communication signal. The multiplexed communication signal is communicated via a second optical fiber communication medium to a subscriber distribution device.

A method for calculating availability in line power systems composed of power circuit modules determines power circuit parameters associated with the power circuits, accepting input from central databases. The method calculates a required number of power circuits to complete the line power system, and calculates the total power to be delivered over the power system, based on a power calculator. The method calculates individual power circuit availabilities based on die power circuit compositions and external variables. The method then calculates an overall system availability based on the power circuit availabilities and other external variable inputs. The method may compare the calculated line power system availability with a target availability, revise the power circuit parameters, and recalculate the system availability to meet the target availability.

摘要:
A method in a server for providing various Internet Protocol television signal qualities involves an IPTV signal having a first signal quality that is transmitted over a first network connection to a first device. A request to receive the IPTV signal over a second network connection at a second device with the IPTV signal having a second signal quality is received. A determination is made that the second network connection has sufficient bandwidth to transmit the IPTV signal at the second signal quality, and that the second device is capable of receiving IPTV signal. The transmission of the IPTV signal over the first network connection to the first device is ended. An endpoint for the transmission of the IPTV signal to the first device is determined. The IPTV signal is transmitted over the second network connection to the second device at the second signal quality beginning at the determined endpoint.
摘要:
A method is disclosed for determining a mitigation strategy to limit a potential source of interference on an Internet Protocol television (IPTV) system. A new user installation request is received at a server in the IPTV system. A first geographical location of a customer premises associated with the new user installation request is received. A second geographical location of an amplitude modulation broadcasting facility is received. The first geographical location and the second geographical location are plotted. A first distance between the first geographical location and the second geographical location is determined. A first signal transmission power rating for the amplitude modulation broadcasting facility is retrieved. A first mitigation strategy to limit a first interference of the amplitude modulation broadcasting facility on an IPTV signal provided to the first geographical location when the first distance is less than the first threshold distance is determined.

A method in a server for monitoring an Internet Protocol television (IPTV) service for a customer premises is disclosed. A first geographical location of a customer premises is retrieved, and a second geographical location of an amplitude modulation broadcasting facility within a threshold distance from the customer premises is retrieved. A first signal transmission power rating for the amplitude modulation broadcasting facility during daytime hours is retrieved, as is second signal transmission power rating for the amplitude modulation broadcasting facility during nighttime hours. A time of day that the IPTV service failure occurs is determined based on the first signal transmission power rating for the daytime hours and the second signal transmission power rating for the nighttime hours.
