Abstract

Abstract A communication unit connected to Integrated Services Digital Network line comprises a caller management unit 2. This caller management unit comprises a line monitor (3) for monitoring in-house lines (4, 5) and detecting a caller side calling code included in a calling set up message applied at the time of reference, and a control unit (14) for storing the calling code detected by the line monitor (3) into a predetermined region (15b) of a memory (15). The control unit comprises circuitry for reading out the stored calling code from the predetermined region (15b) of the memory (15) in response to an output request and producing information corresponding to the calling code. The management unit (2) further comprises a unit (16) for displaying the information produced by the control unit. The memory (15) comprises a region for storing the detected calling code, as well as a memory region (15a) for storing plurality of predetermined calling codes and caller specification information corresponding to each calling code. The control unit (14) stores the detected calling code into the memory region (15b) in response to the response side non-response detection to reference by the line monitor (3). The control unit (14) further makes a determination whether a calling code coinciding with the calling code stored in the memory region (15b) is stored in the memory region (15a) in response to an output request, for applying the caller specification information corresponding to the calling code to the output unit (16) when coincidence is detected, while applying only the detected calling code to the output unit on non-coincidence detection.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 129 words
A communication unit in a digital communication network in which a calling set up message is transmitted to a response side at the time of calling, said calling set up message (13a) including a calling code (11) specifying a caller, comprising: detecting means (3) responsive to transmission of said calling set up message to said response side for detecting said calling code from said calling set up message, storing means (14) for storing the calling code detected by said calling code detecting means into a first predetermined memory region of memory means (15), producing means (14) accessing said memory means in response to an output instruction for producing information corresponding to said detected calling code, and indication means (16) to receive information produced by said producing means for indication.
Claim 2
Dependent Claim 129 words
A communication unit in a digital communication network in which a calling set up message is transmitted to a response side at the time of calling, said calling set up message (13a) including a calling code (11) specifying a caller, comprising: detecting means (3) responsive to transmission of said calling set up message to said response side for detecting said calling code from said calling set up message, storing means (14) for storing the calling code detected by said calling code detecting means into a first predetermined memory region of memory means (15), producing means (14) accessing said memory means in response to an output instruction for producing information corresponding to said detected calling code, and indication means (16) to receive information produced by said producing means for indication.
Claim 3
Dependent Claim 54 words
The unit according to claim 1, wherein said detecting means comprises means (3) for detecting a non-response to said calling set up message by said response side, and said storing means comprises means (14) responsive to a non-response detection by said non-response detecting means for storing said detected calling code to said memory means.
Claim 4
Dependent Claim 142 words
The unit according to claim 1, wherein said memory means comprises a second memory region for storing plurality of preselected calling codes, and caller specification information corresponding to each of said plurality of calling codes, and said producing means comprises means (14) for reading out the contents of said first memory region in response to said read out instruction to determine whether or not a calling code coinciding with said read out calling code is stored in said second memory region, first producing means (14) for reading out caller specification information corresponding to said detected calling code from said second memory region and applying the same to said indication means, when said determination means shows a coincidence detection, and means (14) for applying only said detected calling code to said indication means in response to a non-coincidence detection by said determination means.
Claim 5
Dependent Claim 30 words
The unit according to claim 3, wherein said first producing means comprises means (14) for applying said detected calling code along with said caller specification information to said indication means.
Claim 6
Dependent Claim 37 words
The unit according to claim 1, wherein said producing means comprises means for reading out a calling code stored in said first region in response to said output instruction, to apply the same to said indication means.
Claim 7
Dependent Claim 109 words
A communication method in a digital communication network in which a calling set up message is transmitted to a response side at the time of calling, said calling set up message (13) including a calling code (11) specifying the caller, comprising the steps of: detecting said calling code from said calling set up message in response to the transmission of said calling set up message to said response side, storing the detected calling code into a first predetermined region of memory means (15), accessing said memory means in response to an output instruction for producing information corresponding to said detected calling code, and receiving the produced information for indication.
Claim 8
Dependent Claim 109 words
A communication method in a digital communication network in which a calling set up message is transmitted to a response side at the time of calling, said calling set up message (13) including a calling code (11) specifying the caller, comprising the steps of: detecting said calling code from said calling set up message in response to the transmission of said calling set up message to said response side, storing the detected calling code into a first predetermined region of memory means (15), accessing said memory means in response to an output instruction for producing information corresponding to said detected calling code, and receiving the produced information for indication.
Claim 9
Dependent Claim 62 words
The method according to claim 6, wherein said detecting step comprises the step of detecting a non-response to said transmitted calling set up message by said response side, and said storing step comprises the step of storing said detected calling code into said first predetermined memory region of memory means (15) in response to a non-response detection by said non-response detecting means.
Claim 10
Dependent Claim 133 words
The method according to claim 6, wherein said memory means comprises a second memory region for storing plurality of preselected calling codes and caller specification information corresponding to each of said plurality of calling codes, and wherein said producing step comprises the steps of reading out the contents of said first memory region in response to said read out instruction for making a determination whether or not a calling code coinciding with said read out calling code is stored in said second memory region, reading out the caller specification information corresponding to said detected calling code from said second memory region when said determination result shows coincident detection to apply for said indication, and applying only said detected calling code in response to a non-coincidence detection by said determination means for said indication.
Claim 11
Dependent Claim 44 words
The method according to claim 8, wherein the step of reading out from said second memory region and applying for said indication comprises the step of providing not only said read out caller specification information, but also said detected calling code for said indication.
Claim 12
