摘要:
A test unit for determining whether a local telephone company demarcation point device is providing telecommunication signals to one of a plurality of telephone lines of a telephone system includes: a demarcation point connector that is configured to interface with a connector of the demarcation point; a telephone system connector that is configured to interface with a connector of the telephone system; a plurality of switches, each of the switches being configured to selectively connect a connection site of the demarcation point device with a corresponding connection site of the telephone system, the selective connection providing a telephone line therebetween; and an indicator that signals whether a designated connection site of the demarcation point device is providing telecommunication signals to its respective telephone line.

In order to provide in-region, interLATA service, a bell operating company (BOC) must provide telecommunications service to competitive local exchange carriers (CLEC) in a non-discriminatory manner. To demonstrate that the BOC service to the CLEC is non-discriminatory, the BOC provides a series of performance measures to regulatory agencies and to the CLEC. A system and method is described for ensuring the quality of those performance measurements. The system and method provide for identifying sub-processes within a performance measurement process (PMP), identifying critical audit points within each sub-process, and implementing control measures corresponding to each critical audit point. The system and method help to eliminate the need for time-consuming and expensive third-party audits of the PMP.

Monitoring calls in compliance with a law enforcement regulation or governmental law or order in a telecommunications network is provided. A law enforcement application executes commands that effect the law enforcement regulation. A primary rate interface (PRI) coupled to the law enforcement application redirects calls to be regulated by law enforcement regulation. A method for effecting a law enforcement regulation in a telecommunications network provides a law enforcement application is that regulates calls and a primary rate interface (PRI) for redirecting the calls to be regulated by law enforcement regulation.

It is a problem to provide a system allowing an addressee to set the RBT of an addresser. The tone information providing system has a receiving section for receiving calling information which is transmitted from a mobile phone used by a user and which includes an addresser number for specifying the mobile phone and an addressee number for specifying the mobile phone of a calling destination, a tone information selecting section for selecting tone information corresponding to the addressee number out of tone information stored in a tone information storing section in which an addressee number and tone information are related each other and stored, a transmitting section for transmitting the selected tone information to a mobile phone, and tone information recording section for relating an addresser number, addressee number and tone information each other to store them in a past-record information storing section.

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.

An equivalent working length (EWL) determinative system (11) for use in a digital subscriber line (DSL) telecommunication network (10) is provided. The EWL system (11) includes a DSL circuit (32) having a customer site (14) with customer premises equipment (30). The customer premises equipment (30) receives and transmits communication signals and generates a first attenuation signal in response to the communication signals. A remote terminal (20) forms a loop (31) with the customer site (14) and has a loop length. The remote terminal (20) includes a remote terminal transceiver (40) that is in communication with the customer premises equipment (30). A main controller (37) is electrically coupled to the customer premises equipment (30) and determines an EWL of the loop (31) in response to the first attenuation signal. A method of performing the same is also provided.
摘要:
Method and system are provided for optimization and transmission of digital signals through twisted pairs of telephone cables. Crosstalk reduction is obtained due to cancellation of electromagnetic fields generated by correlated twisted pairs by establishing mutual pair-to-pair coherence at each tone of a transmission spectrum and introducing a requested phase shift between the tones propagating in different pairs.

A telephone plug-in jack or pair of jacks are attached with one on each side of the casing on a telephone test set. The telephone plug-in jacks are telephonically connected to the telephone test set clips which attach to telephone lines. Computer modems and other equipment with telephone plugs may be plugged into the test set for outside telephone access when the clips are attached to the telephone wires.

A telecommunication terminal device includes a network connection unit having at least a first pin and a second pin to which a public telephone network is connected, and a third pin and a fourth pin through which a first external terminal device of a first type is connected to the first and the second pins; a first switching unit for selectively connecting the public telephone network with the first external terminal device and a second external terminal device of a second type; a first external terminal connection unit having a fifth pin and a sixth pin through which the second external terminal device is connected to the first and the second pins; and a feeding circuit connected to the first and the second pins to keep flow of currents provided from the public telephone network. The telecommunication terminal device is capable of exchanging telecommunication signals regardless of serial or parallel connection to additional external terminal devices.
