摘要： A method for use in an electronic switching system (ESS) analyzes M.times.N sets of line signals communicating between itself and at least one other ESS. At a first step, two previous sending and receiving line signals for a voice channel from each of the two ESS's are provided as a first pair of line signals. At a second step, two current sending and receiving line signals from each of the two ESS's form a second pair of line signals. At a third step, each of the line signals in the second pair is compared with its corresponding line signal in the first pair to check whether at least one line signal in the second pair is different from the corresponding line signal in the first pair. At a fourth step, if the checked result is negative, the second and the third steps are repeated for a predetermined duration, and if otherwise, a time interval value between one of the line signals in the second pair and its corresponding different line signal in the first pair is calculated. At a fifth step, it is checked that the calculated time interval value exists within its corresponding range among a predetermined set of ranges of time duration of line signals of the channel to determine the status of the different line signal in the first pair. At a final step, the steps from the second to the fifth are repeated until all of M.times.N sets of line signals of N voice channels are processed.

摘要： An electronic private branch exchange includes a first fault detection portion, a first alternate control portion, a second fault detection portion, and a second alternate control portion. The first fault detection portion detects occurrence of a fault on a private line for connection to a remote electronic private branch exchange (EPBX). The first alternate control portion selects one of a plurality of integrated services digital network (ISDN) lines registered in advance after the first fault detection portion detects occurrence of the fault, thereby forming a first alternate communication path for alternate connection to the remote EPBX. The second fault detection portion detects occurrence of a fault on a first alternate line formed by the first alternate control portion. The second alternate control portion selects one of the ISDN lines registered in advance except for an ISDN line on which occurrence of a fault has been detected after the second fault detection portion detects occurrence of the fault, thereby forming a second alternate communication path for alternate connection to the remote EPBX.

摘要： A telecommunications system having 1:n group facility protection is disclosed. Two cross-connects are provided, each organized in a distributed fashion, and which have a group of member ports bidirectionally coupled to one another in corresponding fashion via a plurality of paths, such as of the DS-3 data frame type. Each of the cross-connects also include a bidirectional protection port, coupled to the protection port of the other cross-connect by way of a protection path, also preferably of the DS-3 type; the protection port for each cross-connect is assigned to the member port group, and is implemented to be managed by the same distributed interface processing unit as the protected member port group. The cross-connects monitor their member input ports for received facility errors, such as signal failures or excessive failure rates, and request a third-stage bridge from its mate cross-connect in the event of such error. Upon receipt of a good signal at the protection input port, the requesting cross-connect effects a first stage switch, so that the previously failing facility is received over the protection path. Communication of request and acknowledge signals over the protection path is preferably by way of the C-bit and X-bit channels, for DS-3 paths. The switch preferably reverts to the normal condition responsive to the facility becoming valid for a timeout period at the original member port.

摘要： The present invention provides a method of testing a transmission line from a copper access network. The transmission line is tested to generate values for a plurality of network parameters. Using previously determined test results, it is possible to calculate an estimate of the length of the transmission line based on the values of each of the measured parameters. These estimates of the transmission line length can then be used to compute a weighted average of the transmission line length. An inference of the condition of the transmission line can be made by comparing the estimates of the length of the transmission line with the weighted average length.

摘要： Methods and apparatus to measure market share for VoIP carriers is disclosed. An example method includes querying a plurality of VoIP carrier servers to determine the VoIP carrier server that owns the telephone subscriber number (SN), in response to the querying, receiving a plurality of messages operable to determine whether the telephone SN is found within any one of the plurality of VoIP carrier servers, when the received plurality of messages is at least one of inconclusive or when the telephone SN is not found within any one of the plurality of VoIP carrier servers, placing a first partial call to the telephone SN from a first VoIP number within a first VoIP carrier network, receiving a first signal from the first VoIP carrier network, and based on the first received signal, determining whether the telephone SN belongs to the first VoIP carrier network.
