Abstract
Abstract In a telecommunications system in which much of the addressing information needed for call-setting is relatively complex, a directory storage unit (DSU) (which may be replicated in the interests of system integrity) is provided which serves the whole system which may include a number of exchanges (E1, E2, ...). When a call which needs such information is to be made, the initial <<dialling>> by the calling subscriber sets up a connection (1) to the directory storage unit (DSU) as a result of which the appropriate addressing information is sent to the caller's terminal. At the caller's terminal it is stored temporarily, with protocol addition as necessary and the connection to the directory storage unit (DSU) is broken down. A new and separate connection (2) is now set up to the wanted line under control of the information from the directory storage unit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
A data handling system, which includes a directory storage unit (DSU) accessible to a number of user's lines, characterised in that to obtain the information which may include the address of a wanted line (Y) or other termination a calling user (A) sets up a connection (1) through the system to the directory storage unit (DSU) and signals thereto the identity of the information required, in response to the reception of the identity signals the directory storage unit transmits the required information to a storage device (15) associated with the system control equipment, whereafter the connection (1) to the directory storage unit is broken down, and in which in response to the reception of the required information in the storage device (15) a connection (2) is set up in respect of the required address, either immediately or at a desired but later time, or other operations appropriate to that information are performed.
Claim 2
Dependent Claim
152 words
A data handling system, which includes a directory storage unit (DSU) accessible to a number of user's lines, characterised in that to obtain the information which may include the address of a wanted line (Y) or other termination a calling user (A) sets up a connection (1) through the system to the directory storage unit (DSU) and signals thereto the identity of the information required, in response to the reception of the identity signals the directory storage unit transmits the required information to a storage device (15) associated with the system control equipment, whereafter the connection (1) to the directory storage unit is broken down, and in which in response to the reception of the required information in the storage device (15) a connection (2) is set up in respect of the required address, either immediately or at a desired but later time, or other operations appropriate to that information are performed.
Claim 3
Dependent Claim
194 words
An automatic telecommunication system which includes a directory storage unit (DSU) accessible to a number of subscribers' lines which may be connected to the same exchange or to a number of exchanges (El, E2, E3, E4) in the system, characterised in that to obtain the address of a wanted line (Y) or other termination connected to the system a calling subscriber (A) sets up a connection (1) through the system to the directory storage unit (DSU) and signals thereto the identity of the wanted line or other termination, in which in response to the reception of the identity signals the directory storage unit signals thereto the identity of the wanted line (Y) or other termination, in which in response to the reception of the identity signals the directory storage unit (DSU) transmits the required address to a storage device (15) in the system control equipment, whereafter the connection (1) to the directory storage unit is broken down, and in which in response to the reception of the required address in the storage device a connection (2) is set up in respect of the required address, either immediately or at a desired but later time.
Claim 4
Dependent Claim
194 words
An automatic telecommunication system which includes a directory storage unit (DSU) accessible to a number of subscribers' lines which may be connected to the same exchange or to a number of exchanges (El, E2, E3, E4) in the system, characterised in that to obtain the address of a wanted line (Y) or other termination connected to the system a calling subscriber (A) sets up a connection (1) through the system to the directory storage unit (DSU) and signals thereto the identity of the wanted line or other termination, in which in response to the reception of the identity signals the directory storage unit signals thereto the identity of the wanted line (Y) or other termination, in which in response to the reception of the identity signals the directory storage unit (DSU) transmits the required address to a storage device (15) in the system control equipment, whereafter the connection (1) to the directory storage unit is broken down, and in which in response to the reception of the required address in the storage device a connection (2) is set up in respect of the required address, either immediately or at a desired but later time.
Claim 5
Dependent Claim
100 words
A system as claimed in claim 2, characterised in that the required address as extracted from the directory storage unit (DSU) is also displayed on a display (17) at the calling subscriber's instrument (A), in which if the connection is to be set up immediately the subscriber signals to that effect, whereafter call setting occurs, and in which if the call is to be set up at a desired later time the subscriber signals to that effect, the control equipment in response to such signalling setting up the required connection at the desired time by means of a timer 18.
Claim 6
Dependent Claim
53 words
A system as claimed in claim 2 or 3, characterised in that the address as extracted from the directory storage unit in response to a call from a subscriber at one line can be used to set up a connection between two others of the lines or other terminations served by the system.
