To produce a telecommunications system and terminal equipment, which brings about immediate action for important incoming calls. User information in an incoming call is evaluated according to predetermined criteria, and a message is sent to the recipient at his current location. The data received as a result of an incoming call are evaluated by a data processing installation or a telecommunications terminal, and a message is dispatched. The message reaches the called party, who is able to retrie...

A connecting panel assembly including pivot modules that are pivotally connected to a frame of the assembly. The pivot modules include a plurality of jack modules. The jack modules have a plug opening on one side and wire terminations on an opposite side. The pivot modules are pivotally coupled at opposite ends of the frame. The pivot modules can pivot from a closed position wherein the pivot modules are aligned parallel with the frame, and an open angled position wherein the pivot modules are p...

In a packet switched network, first said network address are allocated to a first mobile node being served via a communications link by a first access node, at least a first routing path in related infrastructure being directed to the first access node for the first network address.Routing in said infrastructure is altered when the first mobile node receives service from a second access node, such that at least a second routing path in the infrastructure is directed to the second access node for...

A telecommunications network includes a management system for analyzing call detail records (CDR's) from terminating switches. The management system recovers CDR's by polling through switch managers which poll dependent exchanges. CDR's indicating a call clear occurring within a short predetermined time after a call answer are stored and used to indicate potentially faulty access network lines.

Routing of packets is controlled in a connectionless routing protocol network including an infrastructure of packet switching nodes interconnected by packet transport links, and a plurality of access nodes to which a routing path, defined by data held in packet switching nodes located along said routing path, may be directed in the infrastructure for a given network address.

A method of telecommunications involving a train of binary signals. A predetermined number (a frame) of the signals is stored in a first register. There are second, third and fourth registers, each of which stores a different number of binary digits, but the total digits stored in the second, third and fourth registers equals the total storage capacity of the first register. The digits are read out of the first register into the second, third and fourth registers. There are three carrier waves f...

A telephone switch system is connected digitally to an external computer system operating database software and having access to a digitally stored database of information used by the switch. The switch performs data transactions on the database in the manner of a client. The database engine allows live queries, which automatically update querying clients as pertinent data changes. The database engine also allows query concentration, which caches query results and supplies the cached results to ...

A security node disposed in the telecommunications network connecting calling and called parties transforms information (which can be voice, data, facsimile, video and other types of calls or messages) encrypted in a first format to (a) encrypted information in a different format or to (b) non-encrypted information, and vice-versa. The node is accessible from any location connected to the network. By routing calls or messages originated by the calling party and destined for the called party via ...

A multiplexer device for multiplexing and demultiplexing signals between a low-speed network including 28 DSX-1 signals and a relatively higher speed network including a DS-3 signal. The multiplexer device includes 7 quad DSX-1 cards and 1 spare card. The spare card is connected to the other 7 DSX-1 cards in a fashion that allows the spare card to automatically be switched in for one of the DSX-1 cards or to allow interface electronics on the spare card to replace selected ones of the interface ...

A telecommunications switch has a matrix architecture of n.times.m bus-interconnected, or space-switch interconnected, switch nodes together with additional switch nodes and n.times.m switch peripherals connected to the switch nodes externally of the bus (space-switch) interconnected switch node matrix. Fault protection redundancy is provided by providing each one of the peripherals with connections to two different switch nodes only one of which is enabled at any one time.
