Abstract: 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 the 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.

A system that incorporates teachings of the present disclosure may include, for example, a method having the steps of searching (306) for topology information of a selected CCI coupled to a central office for distributing telecommunication services to one or more buildings, and identifying (310-318) according to said topology information a backup power source capable of supporting a load requirement of the CCI.

Abstract: A system and method are disclosed for configuring power loops between a central office (CO) 106 and a service access interface (SAI) 110. A system that incorporates teachings of the present disclosure may include, for example, a network management system (NMS) 100 having a memory 104, and a controller 102. The controller is programmed to retrieve (206) topology information relating to a selected power loop originating at a CO and terminating at an SAI, identify (207) environment conditions to be applied to the selected power loop, and determine (208, 218) from the topology information and the environment conditions whether the power loop can carry sufficient energy without exceeding a temperature rating.

Abstract: Method of collecting data from one or more network elements used to support customer networks. The method may include compiling a customer list from information extracted from a customer information database and an operation processes database. The customer list may be used to indicate one or more customers, the network elements associated therewith, and network addresses for each of the listed network elements. The method may include automatically generating data collection messages to the network addresses specified in the customer list.

Abstract: A system and method is provided for selecting an option for expanding a communication service into a service area. Expansion options are based on a state of the existing network, demographics, and fiber topology. A list is made of available options. Costs for each option are calculated. Expected revenue associated with each option is also calculated. Selection of an option is based in part on an expected cost and expected revenue associated with the option.
