A submarine telecommunications cable assembly includes a section of main submarine telecommunications cable electrically connected to a short length of cable extending from a repeater housing, the section of main cable being armoured at least in the proximity of the repeater. The electrical connection of the section of cable to the short length of cable extending from the repeater housing is positioned at a location spaced from the repeater housing and strengthening means are provided along the ...

The present disclosure relates to a connector having a connector body. A housing mounts over the connector body. The housing is adapted for securing the connector to another element such as a piece of telecommunications equipment.

A telecommunications system and a method for use in a telecommunications system is disclosed. The system comprises at least one station, means for determining the location of said station in said system, and means for providing information on said location of said station to a location service client The system is also provided with means for defining in dependence on information relating to the client, the accuracy of the location information to be provided to the client. Different accuracy cla...

This invention relates to arrangements for interconnecting a plurality of stand-alone switches by data and communication channels (the latter typically used for communicating voice signals) in such a way as to make the plurality of switches act as if they were one switch. The invention further relates to arrangements for permitting groups of lines, the groups connected to different stand-alone switches, to be treated essentially as if they were connected to a single switch. Each switch of a symb...

In a telecommunications network having some high mobility subscribers, for which no most likely access point can be determined and the subscriber numbers of which do not include immediate information of the actual location of a subscriber, there are also some semi-fixed subscribers and/or fixed subscribers, for which it is possible to determine their most likely access point and the subscriber numbers of which indicate their most likely access point. In case of incoming calls, the first exchange...

In a telecommunications network of the kind which handles non-time-critical calls (NTCC) in addition to normal telephony, a congestion indication is transmitted to NTCC transmitting platforms if volume and/or rate limit for a particular communications route or switch is exceeded. Transmitting platforms (9,10,11) establish a transmission rate based on a gapping ration (GR). On receipt of a congestion signal the platforms calculate and Inter call delay based on a random number multiplied by a weig...

Testing of pre-ringing signalling in a telecommunications network at customer's premises, for example, signalling to activate a caller display unit may be effected remotely. By establishing a test call through the network by way of a dial-back loop to a test telephone number, establishing a second call through the network to the required telephone and simulating pre-termination conditions at network termination, actual signalling tones at the network edge are monitored by corresponding apparatus...

A telecommunication system having a cellular mobile telephone system in which calls from cellular telephones are routed through a mobile service switching center exchange. Users of the system, having control of respective groups of mobile telephone are able via user terminals to access respective databases in a signalling processor and to place in the data base information about call parameters, such as call restrictions, for ones of the telephone of that user controlled group. When a call is ma...

In a mobile communications system each radio unit (14,16) is associated with a respective base station (12) as its `home` base station; any radio unit can communicate with any base station in whose service area it is located. Each base station has a radio interface (20) for communication with radio units, a telephone interface (24) for connection to a telephone line, for example via a PABX (44), and a LAN interface (28) for connection to a local area network (40) to which all the base stations a...

In a telecommunications time division multiple (TDMA) optic network system, network termination equipments (NTE's) are enabled to communicate with a head end by the NTE encoding a message as a signal including error correction on the existing signal traffic, monitoring the errors at the head end and extracting the message from the errors.
