Translation of "Ortsvermittlungsstelle" in English

Exchange EX 1 can assume the functions of a local exchange.

The service switching point 1 shown is used in the present case as a local switching centre.

The user data streams are then processed in a conventional local exchange of the PSTN/ISDN network.

From this local switching office, the connection is finally switched through to the requested employee of the bank.

An example of a consolidating-type interface between an access network and a local exchange is the V5.2 interface.

The latter supplies the voice and signaling information to a local exchange LE via a V5.2 interface.

The announcement is then transmitted from the central announcement center via the local switching center to the caller.

In the absence of such agreement, NRAs should ensure that alternative operators are informed no less than 5 years, where appropriate taking into account national circumstances, before any de-commissioning of points of interconnection such as the local loop exchange.

So, even when the local exchange is broadband equipped and the customer is less than 5km from the exchange, the local loop copper cable into the home or business may be of no use for DSL broadband provision.

An important competition concern from the point of view of infrastructure is the promotion of competition in the last link between the local exchange and the consumer (the local loop).

Following its decision to require the incumbent operator to provide flat rate interconnection in May 2000, the United Kingdom regulator determined in February 2001 that FRIACO should be provided at a higher level in the network rather than at local exchanges, making it easier for new entrants to offer flat rate services because it removes the need for them to invest in capacity to reach local exchanges.

The local loop refers to the physical circuit between the customer's premises and the telecommunications operator's local switch or equivalent facility.

The local switching station 26 is connected, in the usual manner, to the regional and long-distance plane of the telephone network via electrical cables and/or to data networks for data connections and/or to broadband networks, for example, cable television networks, for broadband services.

In these local exchanges just one single group of connection lines can be provided consisting of the lines L1 and L2 via which outgoing trunk telephone connections are established from the local exchange (in the drawing illustrated above the dash-dotted line).

What is thereby advantageous is the avoidance of compatibility problems, since analog connections are possible from a telecommunication subscriber station designed and connected in the specified manner to pure analog telecommunication stations, as well as to telecommunication subscriber stations equipped in the manner specified above and, on the other hand, digital connections are possible to telecommunication subscriber stations equipped in the specified manner, as well as to pure digital subscriber stations, wherewith the possibility is provided, if need be, of only designing and connecting individual telecommunication subscriber stations of a traditional local exchange or of a PBX system in accordance with the invention.

The subscriber-assigned information signals to be transmitted from the center 1 to the subscribers originate from a local switching center 4 located in the center, to which the subscribers in question are connected by means of the fiber-optic network.

Each subscriber thus has two of the input and output lines of the local switching center 4 shown.

For these, a converter circuit (not shown) is present, which carries out the signal conversions required between the local switching center 4 and the modulating and demodulating devices 5 and 8, respectively, e.g., the conversion from two-wire to four-wire operation and conversions of ringing signals, dialing signals and signaling characters.

As described above, a demodulation device 8 ensures that each subscriber-assigned input line of the local switching center 4 will have supplied to it precisely the signal intended for it, from among the subscriber-assigned signals.

The local switching center 4 feeds the subscriber-assigned signals to be transmitted to these subscribers via 1024 parallel output lines into a modulation device 5, which converts the large number of signals into a frequency-division multiplex signal with subscriber-assigned frequencies, which, in the frequency plan according to FIG.

The radio communication network as claimed in claim 1, wherein several cordless subscribers are permanently allocated to one cordless network terminating unit of the local exchange.

The radio communication network as claimed in claim 1, wherein means for call diversion are provided in the local exchange, said means for call diversion being activated for cordless subscribers which are located within a radio zone of a different cordless network terminating unit.

The radio communication network as claimed in claim 5, wherein a cordless subscriber has a mobile section and a wire line, and wherein in the local exchange the call is automatically diverted from the wire line to the mobile section when the subscriber does not respond at the wire line or the call diversion facility is activated.

The drawing illustrates a local exchange (above the dash-dotted line) and a trunk exchange (below the dash-dotted line).

If the subscriber in question wishes to establish a trunk connection, following the traffic distinguishing digit zero he dials a multidigit local code number which governs the trunk connection which is to be established and which characterizes a specific remote local exchange.
