Definitions

• the invention relates to a transmission method according to the preamble of claim 1.
• control and monitoring information It is known to transmit control and monitoring information to network elements, for example subscriber lines or switching stations, in telecommunication network networks.
• these network elements are software-controlled, so that control and monitoring information must be transmitted when the network elements are reprogrammed or converted. For example, updated software versions, new numbering plans or other changes, for example a change in the duration of a telephone unit, are transmitted via a remote data transmission line.
• the network elements have service interfaces, so that an analog service access via modem and / or a digital service access via ISDN is possible. This allows the Transfer control and monitoring information to the corresponding network elements via the public telecommunications network.
• the control and monitoring information is preferably provided with an identifier so that it is assigned to a specific network element. This makes it possible to influence individual network elements in a targeted manner.
• a service unit which is formed, for example, by a service PC, is used to transmit such control and monitoring information.
• a disadvantage of the prior art is that when the network elements are checked on site, for example in order to check software changes or the like on a random basis, the executing service technician in most cases wishes to be contacted with his service center, whereby at least one subscriber line is seized got to. As a result, the participant may be limited because its connection to the public telecommunications network is temporarily occupied.
• the method with the features of claim 1 has the advantage that in a communication channel, via which control and monitoring information that directly influences the device is transmitted, service information that can be freely entered can also be transmitted.
• service information that can be freely entered can also be transmitted.
• a separate service channel can advantageously be dispensed with. There is therefore no need for a separate channel in which freely enterable service information is preferably transmitted in the form of speech.
• Another advantage is that it is not necessary to use the subscriber line for inquiries with the service center.
• the control and monitoring information which directly influences the device is transmitted in particular by connecting a service personal computer (service PC) which is connected to a network element via an interface, preferably a V24 interface.
• service PC service personal computer
• the control and monitoring information to be transmitted from the service PC to the network element is preferably provided with an identifier, so that addressing to a specific network element can be provided, that is to say the control and monitoring information is only transmitted to the network element which corresponds the addressing or identifier should be addressed.
• the service unit can be used for the transmission of the service information, which preferably also for Transmission of control and monitoring information is used.
• voice or text can be transmitted via the communication channel.
• the service PC ie the service unit
• the service PC has a speech and hearing device for voice transmission. No additional devices are required on the service PC to transfer texts, since a keyboard is already available that can be used for text input. Ready-made texts or freely formulated texts can be transmitted as text information.
• the service information can be transmitted bidirectionally. This means that the service technician can talk on site at the network element and the partner in the service center.
• the service information can preferably be transmitted to each network element by predeterminable addressing.
• the single figure shows a block diagram of a section of a telecommunications network.
• the telecommunication network is an active optical network (AON, Active Optical Network) with a point-to-multipoint transmission possibility (PMP, point to multipoint).
• AON Active Optical Network
• PMP point to multipoint
• wire network in which the information is transmitted in the form of electrical signals. It can also be a passive optical network.
• the figure shows sections of an optical telecommunications network, hereinafter referred to as network 1.
• the network 1 has at least two, here five network elements 2, which are connected to one another via optical fibers, hereinafter referred to as LWL 3.
• the network 1 is arranged here in a star-shaped manner purely by way of example, network arrangements also being conceivable in which the network elements 2 are connected to one another by means of LWL 3 with at least two further network elements.
• a network element 2 here forms a switching station 4, which represents, for example, switching in a post office, not shown here. Subscriber connections 5a to 5d are connected to the switching station 4.
• the switching station is assigned a network management system 6, which is used to control and monitor the network 1.
• the network management system 6 is an operating console which is also arranged in the post office.
• the switching station can preferably be reprogrammed via such an operating console; on the other hand, it is also possible to make software changes or changes to the number.
• a terminal 8 is assigned to the subscriber line 5a, for example via a so-called a / b interface 7.
• a terminal 8 can be, for example, a telephone, a fax device or the like.
• the subscriber lines 5a and 5d are each assigned a service unit 10a or 10b via a service interface 9a or 9b.
• the service unit is, for example, a service PC 11a or 11b, which is also known as a local maintenance terminal (LMT).
• LMT local maintenance terminal
• the service PCs 11a and 11b are not permanently installed on the subscriber connections 5a or 5d, that is to say they are preferably designed to be portable and can of course also be connected to the other network elements 2.
• the OAM signals are transmitted in a communication channel which is independent of the telecommunication transmission of the individual terminals 8, This means that the transmission of the OAM signals takes place via the telecommunication network, but independently of the individual call lines that are formed on the subscriber lines 5a to 5d, for example by the a / b interface.
• the service information is transmitted in the communication channel, in to which the OAM signals are also transmitted.
• the service PCs 11a and 11b have a speech and listening device (not shown).
• the service information can be transmitted in text form within the communication channel. This can be, for example, prefabricated texts or messages, but it is also possible, for example, using a keyboard that is arranged on the service PC 11a and 11b, that is to say individually enter and submit freely formulated texts.
• the OAM signals are transmitted with an identifier or with a protocol, it is possible to transmit the OAM signals in a targeted manner to a network element, here the subscriber line 5d. Since the service information is preferably transmitted together with the control and monitoring information, the service information can also be uniquely assigned to a network element, here the subscriber line 5d. This means that a separate transmission system is not necessary for the transmission of the service information.
• the network management system 6 is also equipped with a speech and listening device (not shown), so that a service technician located at the processing station 4 can also be addressed.
• a speech and listening device not shown
• the service information can be transmitted to any network element or to the service technician located there without a separate or additional transmission system.
