Systems, methods, and a computer-readable storage media for placing a plurality of calls with a common message to a plurality of subscribers are provided. The systems, methods, and a computer-readable storage media include receiving an instruction to place the plurality of calls with the common message to the plurality of subscribers. The instruction includes call information that identifies the plurality of subscribers. One of the plurality of auto-dialers for placing each of the plurality of calls based on the call information is determined, and an instruction is transmitted to each of the plurality of auto-dialers based on results of the determination. The plurality of auto-dialers places the plurality of calls to the plurality of subscribers based on the instruction transmitted to each of the plurality of auto-dialers.

Apparatus, methods and articles of manufacture to predict vectored digital subscriber line (DSL) performance gains are disclosed. A disclosed example method includes determining a model coefficient of a noise-to-margin ratio (NMR) model from performance data measured for a DSL subscriber loop prior to provisioning of vectoring for the DSL subscriber loop, computing, using the model coefficient, a first NMR value with disturbers enabled and a second NMR value with disturbers disabled, and estimating an expected vectoring performance gain for the DSL subscriber loop based on the first and second NMR values.

A communications system for placing a plurality of calls with a common message to a plurality of subscribers via a public switched telephone network is provided. The communications system includes an end office switch disposed in an end office and in communication with the public switched telephone network. The communications system further includes an auto-dialer disposed in the end office and interconnected with the end office switch for placing the plurality of calls to the plurality of subscribers via the end office switch.

A system and method for imputing data into a database includes an imputing system operable to impute data based on outside plant construction principles. The imputing system includes an inventory database, a data engine, a search engine, and a loop engine. The inventory database includes a plurality of distribution records each associated with one or more cable pairs. The data engine determines if a desired distribution record corresponding to a desired cable pair includes missing data. The search engine searches a known class of serving terminals for complete distribution records and iteratively searches a sized binder group within the inventory database for one or more complete distribution records where the size of the binder group searched increases with each iterative search. The loop engine determines an imputed value for the desired distribution record based on the searching and imputes the value into the desired distribution record.

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.

An equivalent working length (EWL) determinative system () for use in a digital subscriber line (DSL) telecommunication network () is provided. The EWL system () includes a DSL circuit () having a customer site () with customer premises equipment (). The customer premises equipment () receives and transmits communication signals and generates a first attenuation signal in response to the communication signals. A remote terminal () forms a loop () with the customer site () and has a loop length. The remote terminal () includes a remote terminal transceiver () that is in communication with the customer premises equipment (). A main controller () is electrically coupled to the customer premises equipment () and determines an EWL of the loop () in response to the first attenuation signal. A method of performing the same is also provided.

A system of evaluating automatic message accounting records associated with telephony calls is disclosed. The system includes correlation logic to collect originating AMA records having an originating call code to identify a record of an originating long distance call and further to collect terminating AMA records that correspond to the collected originating automatic message accounting records. The system also includes evaluation logic to determine when a call may be by-passing terminating access charges by identifying calls that have been correlated with an originating AMA record having the originating code and with a terminating AMA record having a local termination code.

A method and system enable optimization of trunk group design in a public switched telephone network (PSTN). A community of interest, including two end offices connected by a direct trunk and at least one tandem switch, is identified using out-of band signaling data collected from the PSTN. An application server interfaced to the PSTN determines whether traffic in the community of interest passes through the tandem switch during a predetermined time period. When traffic passes through the tandem switch, the application server further determines whether the direct trunk between the end offices experienced an overflow condition during the same predetermined time period. When the direct trunk did not experience an overflow condition, an exchange code associated with the traffic passing through the tandem switch is designated as a misrouted code. The misrouted code is flagged so that associated traffic is redirected through the direct trunk.

A method of evaluating automatic message accounting records associated with telephony calls that originate at a local exchange carrier telephony office and that are routed over an inter-exchange carrier telephony facility is disclosed. The method comprises collecting originating automatic message accounting records associated with the originating local exchange carrier telephony office, and collecting terminating automatic message accounting records that correspond to the originating automatic message accounting records. A first portion of the terminating automatic message accounting records have a terminating access code and a second portion of the terminating automatic message accounting records have a local termination code.
