Abstract: Measures are provided for use in establishing a telephony session between first and second telephony devices in a telephony network. Telephony network equipment in the telephony network receives, from the first telephony device over a signalling link, a telephony session establishment request. The telephony network equipment receives, from the first telephony device over a data link that is separate to the signalling link, a message comprising data useable by the telephony network equipment to identify the second telephony device. The telephony network equipment correlates the received telephony session establishment request and the received message. The telephony network equipment transmits, to the second telephony device, a telephony session establishment request on the basis of the correlating. The first telephony device is associated with a multi-persona user having a first persona associated with a first telephony identifier and a second persona associated with a second telephony identifier.

Abstract: A test matrix switch-associated mechanism conducts an interactive communication session with the butt set of an incumbent local exchange carrier (ILEC) technician, to verify the intended connectivity of a digital subscriber line pair through the switch to customer premises equipment subscribing to digital service from a competitive local exchange carrier (CLEC). Connectivity through the switch is controlled by way of a supervisory control processor that may be downloaded with communication and test control software from a remote test unit, in association with one or more CLECs that are served by the ILEC's central office equipment. Once loaded with this control software, including a routine for executing the connectivity verification mechanism of the invention, the switch's control processor sources digitally synthesized test signals for application to a line under test, and conducts a digitally-based analysis of replies to such signals as supplied by a craftsperson's butt set.

Abstract: A two-ended, line-driving and receiving/tone signal analysis system performs line connection verification applying a low-distortion, low-amplitude test signal to one end of a cable pair under test and monitoring the response of a remote end wireline pair. Preferably the test signal frequency is on the order of 110 Hz, which avoids domestic and foreign AC power signal frequencies and is spectrally equidistant from their harmonics. It also avoids ringing frequencies for POTS lines, and remains safely below the 350 Hz lower limit of POTS and other telephone line system services. In response to application of the 110 Hz test signal to tip and ring segments of a wireline pair at one end of the cable bundle, the energy of the 110 Hz component, as well as that of two other ‘spectrally nearby’ (slightly higher at 112 Hz and slightly lower at 108 Hz), are measured at a tip and ring pair at the far end of the cable plant.

Abstract: A system in accordance with the invention dynamically establishes test connections upon initiation of a test sequence and does not need to maintain permanently “nailed up” test connections. To do so, each node in the system, e.g., COT, RT, maintains a logical bypass pair terminator (“BT”). The BT includes facilities which reserve the requisite channels that will be needed to establish a test connection. When a test sequence is initiated for testing a drop from an RT, a BT facility at the RT will establish a connection to an RT bypass card and a BT facility at the COT will establish a connection to a COT bypass card, thereby completing the test connection.

Abstract: A method employs simple procedures to speedily carry out loopback tests on devices that form a channel system of an exchange. The method is capable of quickly locating a fault in the exchange and allowing speedy maintenance work of the exchange. Also provided is an apparatus for achieving the method. The apparatus has a path setter (1-4), a loopback controller (1-3), and a tester (1-1), to test the devices of the channel system (1-2) of the exchange. The devices to be tested are arranged in replaceable units (1-21, 1-22). The path setter (1-4) simultaneously sets paths to sequentially connect the devices to be tested. The loopback controller (1-3) activates and releases loopback parts arranged in the devices to be tested. The tester (1-1) sends a test signal to the devices through the paths, receives the test signal looped back by the loopback parts, analyzes the received signal, and determines whether or not the devices are sound.

Abstract: A telecommunications system and method is disclosed for providing a cell traffic supervision alarm within a base station (BS) to notify the operator at a Mobile Switching Center (MSC) serving the BS that the BS has had no traffic for a period of time that is unreasonably long. The definition of “unreasonably long” is tied to normal traffic patterns at the BS. An alarm threshold time, which is defined as time between the cessation of all traffic on a BS and the triggering of the alarm, can be calculated based upon a statistical analysis of the traffic history of the BS to determine a time interval such that the probability is acceptably small that under normal conditions the BS would have gone for that entire length of time with no traffic at all. At the expiration of the alarm threshold time, the alarm is activated.

Abstract: In a large switching system, a complete record of a call through a network can be collected by having each switch that processes the call, record pertinent data and return the collected data to a particular switch where the collected data is stored. A complete call history simplifies network maintenance and permits precise identification of calling and called parties on a call-by-call basis.

Abstract: A method and apparatus for testing for correct connection together of circuit elements in a circuit formed of a plurality of redundant circuit portions. A coded signal is generated at a first circuit element and transmitted upon a signal path believed to connect the first circuit element with a second circuit element. If the coded signal is detected at the second circuit element, the correct connection of the first circuit element together with the second circuit element is verified. Because a coded signal is generated, the correct connection between the circuit elements can be verified even when the signal path connecting the first and second circuit elements is formed of an optical, or other non-electrical, coupler.

Abstract: In a telecommunications system, the amount of time a subscriber device is effectively out of service as a result of some fault or failure in telecommunications equipment is monitored. Subscriber devices are connected by corresponding subscriber communication paths to receive information from or transmit information to a telecommunications center such as a local telephone exchange. One or more data records is maintained in computer memory for each subscriber path connected to the communications center. Each data record is updated using recently determined data relating to the operational status of each subscriber path. The computer then determines from the updated record in accordance with one or more subscriber line blocking criteria a subscriber path blocking parameter. The subscriber path blocking parameter may represent for example an average amount of time each subscriber path satisfies the one or more subscriber line blocking criteria.
