Description

The The invention relates to a method for converting address strings for telecommunication systems and an apparatus for using the method.

In Digital communication networks usually have different addressing formats of participant addresses, with which a structure or getting a Connection between telecommunications equipment connected to the communication networks are turned on, takes place. The participant addresses can thereby among other things according to a so-called implicit numbering plan and / or a so-called explicit numbering plan be. For an address following the implicit numbering plan an assignment of a telecommunications area in which the address validity owns, by every single digit of the address. In an address according to the explicit numbering plan exist in coded form present information elements of the address (NPI, TON) containing the Telecommunications area define in which the address validity has.

at a connection between telecommunications equipment, the various Using addressing formats, it is often necessary that the Addressing formats due to adaptation to signaling capabilities the plants are implemented. Often require private telecommunications networks that also within this Nets an officially defined or a private numbering plan should be used. It can therefore addresses on a telecommunication line at the same time the most diverse numbering plans exist.

By a historically conditioned adaptation of telecommunications equipment data processing programs to external Conditions (e.g., official traffic, QSIG protocol with different numbering plans, etc.) is a participant address treatment often very unstructured, which may be too incorrect signaling of subscriber addresses and / or faulty Lead telecommunication connections can. This is essentially because a conversion of the Addresses and a determination of prefixes based on false criteria carried out or that the address data including the prefixes are too inflexible are. Furthermore individual steps of the address translation are performed decentralized, so that this is largely inconsistent.

• – Präfixe werden anhand der falschen Kriterien in die Adressen eingefügt oder aus den Adressen gelöscht, was in falschen Adressen und dadurch bedingt in Verbindungen zu falschen Zielteilnehmern bzw. in nicht möglichen Verbindungen resultiert;
• – ein Signalisieren von unterschiedlichen Telekommunikationsanlagenrufnummern auf verschiedenen Amtsleitungen und/oder auf privaten Netzleitungen ein und derselben Telekommunikationsanlage wird nicht oder fehlerhaft unterstützt;
• – ein Signalisieren von unterschiedlichen Anlagenrufummern auf ein und derselben Amtsleitung wird für unterschiedliche Endgeräte der Anlage nicht unterstützt;
• – ein ISDN-Nummerierungsplan wird auf privaten Netzleitungen (z.B. unter dem QSIG-Protokoll) nicht unterstützt;
• – ein privater Nummerierungsplan wird nicht unterstützt;
• – Leistungsmerkmale diverser Signalisierungsprotokolle, die ISDN-Adressen enthalten, werden nicht unterstützt;
• – Endgeräterufnummern von Telekommunikationsanlagen werden nicht eindeutig signalisiert;
• – Adressen werden mit falscher Kodierung signalisiert.

The following problems may occur, among others:

• - prefixes are inserted into the addresses based on the wrong criteria or deleted from the addresses, resulting in wrong addresses and therefore in connections to wrong destination users or in not possible connections;
• A signaling of different telecommunications system telephone numbers on different trunks and / or on private network lines of the same telecommunications system is not or incorrectly supported;
• - Signaling of different system call numbers on one and the same trunk is not supported for different devices of the system;
• An ISDN numbering plan is not supported on private network lines (eg under the QSIG protocol);
• - a private numbering plan is not supported;
• - Features of various signaling protocols that contain ISDN addresses are not supported;
• - Terminal numbers of telecommunications equipment are not clearly signaled;
• - Addresses are signaled with incorrect coding.

From the DE 100 64 045 A1 a method is known in which address strings are converted exclusively by means of predetermined device data. The conversion is carried out by means of conversion records in the form of filter rules, wherein only in the case that a conversion record is set up for an address string, an old is converted into a new address.

From the EP 0 798 942 A2 For example, a method is known in which addresses are converted from a first to a second format according to a rigid conversion scheme.

It The object of the invention is to provide a method which more reliable Telecommunication connections in heterogeneous telecommunication structures allows. Furthermore, it is the object of the invention to provide a device with the inventive method can be used.

The Task is solved with a method having the features according to claim 1 and with a device with the features according to claim 13.

preferred Further developments of the invention are specified in the dependent claims.

The inventive method sees a build up of an address string from one of a first one Telecommunications equipment used first format in one of one second telecommunication system used second format. In an analysis step of the method, an analysis of the address string takes place in the first format, based on a first numbering plan identifier NPI1 and a first telecommunications area identifier TON1, a subscriber address used by the first telecommunication system in a for the second telecommunication system clear format on one lowest possible Level to determine. In a building step, a build-up takes place the address string in the second format based on the Analysis step determined unique subscriber address on the Based on a second numbering plan identifier NPI2 and a second telecommunications area identifier TON2.

Farther sees the method according to the invention in the analyzing step, converting the first numbering plan identifier NPI1 into a standard numbering plan identifier and converting of the first telecommunications area identifier TON1 in a Standard telecommunications area identifier. Furthermore is in the build step, converting the default numbering plan identifier into the second numbering plan identifier NPI2 as well as a converting of the standard telecommunications area identifier in the second Telecommunications area identifier TON2 provided.

In Advantageously, this is a conversion of a telecommunications equipment used participant addresses in any first format in supports any second format. Furthermore, with the inventive method a support all Address formats (implicit, explicit) and all numbering plans (for example ISDN numbering plan, private numbering plans, etc.) on all telecommunication lines using all Protocols (for example, DSS1, QSIG, private logs, etc.) be achieved.

Thereby is advantageously in the analysis step converting the in the addressing mechanism according to the invention incoming address string to a uniform, explicit ziten Addressing format supported, what a consistent further treatment in the following building step or in mediation processes facilitates the second telecommunications system.

In a further preferred embodiment of the method according to the invention the analyzing step comprises determining one in the subscriber address contained in the first format terminal number of the second telecommunications system.

Thereby is advantageously a correct signaling of different System telephone numbers of a switching system, for example due to a connection to telecommunications networks different Network operator may result. Furthermore, it can a correct signaling of different prefixes of the same Switching system can be achieved on different lines. Furthermore is more useful Assure correct signaling of subscriber addresses in the implicit addressing format to the terminal supported.

Farther is therefore cheaper Way converting the in the addressing mechanism according to the invention incoming address string into a terminal number (Implicit).

In a further preferred embodiment the method according to the invention the analysis and building process is based on facility data the first and the second telecommunications system.

Thereby is an advantage on the two telecommunications systems related individual treatment of the individual steps of the method according to the invention supported.

In a further preferred embodiment the method according to the invention are the setup data of the two telecommunications systems mediation-related and / or telecommunications-related and / or telecommunication terminal-related terms. Thereby can advantageously one on different telecommunications structures (e.g., exchanges, telecommunications lines, terminals, etc.) related, individual processing of the individual steps of the method according to the invention be achieved.

The Invention will be described below with reference to the accompanying drawings. It shows

1 a schematic representation of the method according to the invention;

2 a schematic representation of an application of the method according to the invention to address strings; and

3 a schematic representation of a device with which the inventive method is usable.

• a) Einrichtungsdaten einer eigenen Telekommunikationsanlage für den ISDN-Nummerierungsplan;
• b) Einrichtungsdaten der eigenen Telekommunikationsanlage für den privaten Nummerierungsplan;
• c) Einrichtungsdaten der fremden Telekommunikationsanlage für den ISDN-Nummerierungsplan;
• d) Einrichtungsdaten der fremden Telekommunikationsanlage für den privaten Nummerierungsplan.

The inventive method requires device data of the telecommunications structures involved in establishing and maintaining a telecommunication link between the telecommunication systems for improved functionality. The device data are preferably stored in table form in the following quadruple form:

• a) facility data of its own telecommunications system for the ISDN numbering plan;
• b) installation data of the own telecommunications system for the private numbering plan;
• c) device data of the foreign telecommunications system for the ISDN numbering plan;
• d) facility data of the foreign telecommunications system for the private numbering plan.

The Setup data for the foreign telecommunications system are preferably needed when this is not able to their own asset number and / or prefixes or related Identifier to signal. The inventive method checks in a Address string of the foreign telecommunications system based on Setup data for the foreign telecommunications system, whether this is capable of their Signal plant number. Outgoing address characters to the foreign telecommunication facility are brought into a format which can handle the foreign telecommunications system.

The in the tables stored equipment data of telecommunications equipment are arranged according to a three-level scheme. It is on one first (highest) Level per terminal the telecommunication system specific addressing data stored. This is especially useful if terminals with different system numbers to one and the same telecommunications system are turned on, for example, if terminals of different companies connected to one and the same telecommunications system.

On a second (middle) level of the device data may be for different Trunk group, which are connected to the telecommunications equipment, specific Addressing data stored. This is especially advantageous if a telecommunications system to telecommunications networks of different Network operator is switched on and different on each of these networks System call numbers signaled.

On a third (lowest) level of facility data is per Telecommunications system stored specific addressing data. This can be considered as a standard case, with the addressing data for all terminals and all trunk groups the telecommunications system are identical.

Tabelle 1 The Telekommunikationsanlagerufnummer each telecommunications system is required to unambiguously signal all addresses of this telecommunications system outside the telecommunications system or within a domain. For this purpose, a database accessing the method according to the invention contains the following table:

Table 1

• – Länderkennzahl: Bezeichnung für ein Land oder einen Dienst (z.B. 49 für Deutschland);
• – Nationale Kennzahl: Bezeichnung für eine Stadt oder einen Dienst (z.B. 69 für Frankfurt);
• – Regionale Kennzahl: Anlagenrufnummer der Telekommunikationsanlage (gültig innerhalb einer Stadt);
• – Vorgegebener Einwahlteil der Regionalkennzahl: vorgegebene Durchwahlnummer (falls die tatsächliche Durchwahlnummer dem Dienstanbieter nicht bekannt ist);

For the ISDN numbering plan, the following fields are contained in Table 1:

• - country code: designation for a country or a service (eg 49 for Germany);
• - National code: name for a city or service (eg 69 for Frankfurt);
• - Regional code: PBX number of the telecommunications system (valid within a city);
• - Predefined dial-in part of the regional code: default extension number (if the actual extension number is unknown to the service provider);

• – Stufe-2 Regionalkennzahl: Bezeichnung einer Stufe-2 Region (nicht notwendiger Weise im geographischen Sinn);
• – Stufe-1 Regionalkennzahl: Bezeichnung für eine Stufe 1 Region (nicht notwendiger Weise im geographischen Sinn);
• – Stufe-0 Regionalkennzahl: Rufnummer der Telekommunikationsanlage, die in einer Stufe 1 Region gültig ist;
• – Vorgegebener Einwahlteil der Stufe-0 Regionalkennzahl: vorgegebene Durchwahlnummer (falls die tatsächliche Durchwahlnummer dem Dienstanbieter nicht bekannt ist).

For the private numbering plan, Table 1 contains the following fields:

• - Level 2 regional code: designation of a level 2 region (not necessarily in the geographical sense);
• - Level-1 regional code: designation for a level 1 region (not necessarily in the geographical sense);
• - Level-0 regional code: telephone number of the telecommunications system valid in a level 1 region;
• - Default dial-in part of level-0 Regional code: default extension number (if the actual extension number is unknown to the service provider).

Provided Data not required in Table 1 the corresponding field remains empty.

Tabelle 2 In the event that an explicit address is to be converted into the implicit addressing format by means of the method according to the invention, information which is coded in a "TON" field and represents the telecommunications area identifier must be converted into one or more additional numbers before the address These additional digits are called TON prefixes For this implementation, the telecommunications equipment setup data include the following table:

Table 2

In Table 2 shows that for one's own and for others Telecommunication system Information about the numbering plan as well information about the telecommunications area TON are included. Here are the information about the telecommunications area identifier for the ISDN numbering plan and for the private one Numbering plan designed in three stages. The numerical values for the prefixes of the Telecommunication area identifier for the private numbering plan are freely definable, so these are exemplary in the table to watch. As numerical values for the ISDN-NP are examples of those valid for Germany registered.

Tabelle 3 In the event that an explicit address is to be converted into an implicit address in the method according to the invention, information contained in a numbering plan identifier NPI encoded must be converted into one or more additional digits before the address. These additional digits are called NPI prefixes. The database to which the method according to the invention accesses provides the following table for this reaction:

Table 3

In Table 3 shows that both for oneself and for others Telecommunication system for the ISDN numbering plan and for the private numbering plan information entered for the numbering plan prefix prefix (NPI prefix) are. Here are the NPI prefixes both for the ISDN numbering plan, as well as for the private numbering plan freely definable, the numerical values in the table are therefore exemplary.

For an improved mode of operation of the method according to the invention, each trunk group which is connected to the telecommunication systems and over which connections are established requires indexing at which stage the connections are operated. For example, a line that, based on the ISDN numbering plan from a telecommunications system in Dusseldorf to a Te telecommunication system in Frankfurt, a level designator "National" (could also be "International") have to be unambiguous. A line according to ISDN numbering plan from a telecommunications system in Dusseldorf to a telecommunications system in Paris must have compared to the level designator "International" to be unambiguous.

Tabelle 4 The database accessed by the addressing mechanism according to the invention has the following table for this purpose:

Table 4

For a proper functioning of the method according to the invention must continue to be defined for each trunk group of the telecommunications equipment, in which addressing format addresses are to be signaled to a connected telecommunications system. Possible format specifiers are:

Tabelle 5 For this purpose, the database accessed by the addressing mechanism according to the invention provides the following table:

Table 5

As Tables 1 to 5 are setup data as well as your own as well as for the foreign telecommunications system registered. A quadruple The data entered results from a diversification of the Data for the ISDN numbering plan and the private numbering plan.

Tabelle 6 For a proper operation of the method according to the invention, the line-related device data furthermore requires an indexing according to which numbering plan internal numbers (extension numbers) are to be signaled outside the telecommunications system. For this, the database provides the following table:

The blocks 6 . 7 . 8th . 9 and 10 of the 1 are entry points into an address translation process. The addressing format of Block corresponds to this 1 the addressing format of Block 9 , the addressing format of Block 2 the addressing format of Block 7 , the addressing format of Block 3 the addressing format of Block 6 , the addressing format of Block 4 the addressing format of Block 8th and the addressing format of Block 5 the addressing format of Block 10 ,

The addressing formats of the blocks 6 . 7 . 8th . 9 and 10 can be achieved by the following transformations:
Transformation T1: Conversion of the addressing format of block 6 in the addressing format of block 7
Transformation T2: Conversion of the addressing format of block 6 in the addressing format of block 8th
Transformation T4: Conversion of the addressing format of block 7 in the addressing format of block 9
Transformation T5: Conversion of the addressing format of block 8th in the addressing format of block 10 ,

In the block 11 If there is an implicit format address that is not assigned to either the ISDN numbering plan or the private numbering plan, this is done by a transformation T3 that involves a conversion of the addressing format from Block 6 in the addressing format of block 11 makes can be achieved. Furthermore, the addressing format of block 11 , which may be in the form of an extension number such as 334, can be achieved by the following transformations:
Transformation T3: Conversion of the addressing format of block 6 in the addressing format of block 11
Transformation T6: Conversion of the addressing format of block 9 in the addressing format of block 11
Transformation T7: Conversion of the addressing format of block 10 in the addressing format of block 11

The addressing format of Block 12 corresponds to the addressing format of Block 9 , It is obtained by the following transformations:
Transformation T8: Conversion of the addressing format of block 9 in the addressing format of block 12
Transformation T10: Conversion of the addressing format of block 11 in the addressing format of block 12

The addressing format of the block 13 corresponds to the addressing format of Block 10 , It is obtained by the following transformations:
Transformation T9: Conversion of the addressing format of block 10 in the addressing format of block 13
Transformation T11: Conversion of the addressing format of block 11 in the addressing format of block 13

The addressing format of Block 14 corresponds to the addressing format of Block 7 , It is obtained by a transformation T13 which is a conversion of the addressing format of block 12 in the addressing format of block 14 performs.

The addressing format of Block 15 corresponds to the addressing format of Block 8th , It is obtained by a transformation T14 which is a conversion of the addressing format of block 13 in the addressing format of block 15 performs.

The addressing format of the block 16 corresponds to the addressing format of Block 6 , It is obtained by the following transformations:
Transformation T12: Conversion of the addressing format of block 11 in the addressing format of block 16
Transformation T15: Conversion of the addressing format of block 14 in the addressing format of block 16
Transformation T16: Conversion of the addressing format of block 15 in the addressing format of block 16 ,

The blocks 12 . 13 . 14 . 15 and 16 define "exit points" from the addressing mechanism according to the invention, where the addressing format of the block corresponds 12 an addressing format of a block 17 , the addressing format of the block 14 an addressing format of a block 18 , the addressing format of the block 16 an addressing format of a block 19 , the addressing format of the block 15 an addressing format of a block 20 and the addressing format of the block 13 an addressing format of a block 21 ,

The addressing formats of the blocks 17 . 18 . 19 . 20 and 21 correspond to those of the five "entry blocks" 1 . 2 . 3 . 4 and 5 , In general, the addressing formats of the addresses transferred to the method according to the invention are not identical to the addressing formats of the addresses supplied by the method.

in the The following are the feasible with the method according to the invention individual transformations T1 to T16 explained in more detail. It refers to a Designation "Incoming" to an address string, transmitted from the foreign telecommunications system to its own telecommunications system becomes. A term "outgoing" denotes a Address string used by your own telecommunications system is transmitted to the foreign telecommunications system.

In the case, that an implicit address is converted to an explicit address should be, must in the prefix of the numbering plan identifier (NPI prefix) deleted from the address string and the coded numbering plan identifier must match be set defined. The required operations will be performed in the transformations T1, T2 and T3. The NPI prefixes will be from Table 3. For incoming addresses from the foreign telecommunications system from the database for this purpose, the setup data of the foreign Telecommunication system used. For outgoing addresses will be the device data of the own telecommunications system used.

transformation T1: If included in the implicit address of the NPI prefix for the ISDN numbering plan is, this must be deleted and the coded numbering plan identifier must be set to "ISDN".

Transformation T2: If the implicit address contains the NPI prefix for the private numbering plan, it must be deleted and the coded numbering plan identifier must be set to "private." Transformation T2 thus corresponds to converting the addressing format of Block 6 in the addressing format of block 8th ,

Transformation T3: Unless any of the aforementioned NPI prefixes are included in the implicit address, the address is treated as an internal telephone number. This corresponds to a transition from the addressing format of the block 6 on the addressing format of the block 11 ,

In the case, that an implicit address is converted to an explicit address must contain information in the telecommunications area identifier prefix (TON prefix) is converted to the coded telecommunications area identifier become. Here, the TON prefix from the implicit address deleted become. The required operations are from the transformations T4 and T5 provided. They are only possible if previously the NPI prefix in the encoded numbering plan identifier has been implemented.

The TON prefixes are taken from Table 2. For incoming addresses from the foreign Telecommunications system must in Table 2, the device data of the foreign telecommunications system be taken. For outgoing addresses must the setup data of their own telecommunications system used become.

Transformation T4: If the TON prefix contains "International" in the address, it must be deleted and the coded telecommunications area identifier must be set to "International". This corresponds to a conversion of the addressing format of Block 7 to the addressing format of block 9 ,

In the event that the TON prefix "National" is included in the address, it must be deleted from the address and the coded telecommunications area identifier must be set to "National". This also corresponds to a conversion of the addressing format of Block 7 on the addressing format of the block 9 ,

In the event that neither the international nor the national TON prefix, but the TON prefix "Regional" contained in the address, it must be deleted from the address and the coded telecommunications area identifier must be set to "Regional". Also, in the event that the TON prefix "Regional" is not included in the address, the coded telecommunications area identifier must be set to "Regional" (usually TON prefixes "Regional" are not used.) This also corresponds to a conversion of the Addressing formats of the block 7 on the addressing format of the block 9 ,

Transformation T5: If, according to the private numbering plan, the TON prefix "Level 2" is contained in the address, it must be deleted from the address and the coded telecommunications area identifier must be set to "Level 2". This corresponds to a conversion of the addressing format of Block 8th to the addressing format of block 10 ,

In the event that the TON prefix "Level 2" is not contained in the address, but instead the TON prefix "Level 1", it must be deleted from the address and the coded telecommunications area identifier must be set to "Level 1". This also corresponds to a conversion of the addressing format of Block 8th on the addressing format of the block 10 ,

In the event that neither the TON prefix "Level 2" nor the TON prefix "Level 1" is included in the address, but the TON prefix "Local", it must be deleted from the address and the coded telecommunications area identifier must be on "Local" to be set. Even if the local TON prefix is not included in the address, the coded telecommunications area identifier must be set to "Local." This also corresponds to a conversion of the addressing format of the block 8th in the addressing format of the block 10 ,

Transformations T6, T7:

The inventive method tries to make a deletion of their own telecommunications system telephone number from the address at each incoming address. If this deletion attempt succeeds, the addressing format of the block is 11 the result of this deletion. This addressing format, which corresponds to an internal address or call number, is used as a unique address for storage in a data memory.

In the case, that the deletion attempt the telecommunication system telephone number is unsuccessful the inventive method as many parts of the telecommunications system call number as possible delete the address, to thereby a lowest possible to establish a unique level of the incoming address. This lowest possible unique address will then be for used the data storage. For the case of address signaling becomes the transformations T8 and T9 performed.

For each outgoing address to the foreign telecommunications system, the inventive method for producing a lowest-level uniqueness attempts to delete the telecommunications system telephone number of the foreign telecommunications system from the address. If this Deletion attempt is successful, is the addressing format of the block 11 (internal address of the foreign telecommunications system) the result of this deletion attempt.

These internal address is always sent to the foreign telecommunications system signals, if this is not able, telecommunications system telephone numbers and prefixes to process or signal.

Provided the deletion attempt is not successful, attempts the inventive method as many parts of the telecommunications system call number as possible delete the address, around the lowest possible unique Address level to reach. The telecommunications system telephone number or parts of the same are for it according to the table 1 used. Alternatively, with the help of the transformations T8 and T9 adapted the level of the telecommunications area identifier TON will be described in detail below.

Transformation T6: In the event that the address to be converted is in the ISDN numbering plan and the telecommunications equipment telephone number can be deleted from the address, the coded numbering plan or telecommunications area identifiers are set to "unknown." This corresponds to a conversion of the addressing format of the block 9 on the addressing format of the block 11 ,

Transformation T7: In the event that the address to be converted is in the private numbering plan and the telecommunications equipment telephone number can be deleted from the address, the coded numbering plan identifiers or telecommunications area prefixes are set to "unknown." This corresponds to a conversion of the addressing format of the block 10 in the addressing format of block 11 ,

Corresponding the coded numbering plan or telecommunications area identifier in the original one Address becomes the deletion the telecommunication system telephone number stepwise according to the following Table performed.

Tabelle 7

Table 7

Transformations T8, T9: According to the stage name of the desired telecommunications Onsbereichskennzeichners in Table 4, it may be necessary to increase the telecommunications area identifier in the outgoing direction with the device data of their own telecommunications system, or in the incoming direction with the device data of the foreign telecommunications system. This can be done using the missing address parts according to Table 1.

Transformation T8: (normally for addresses in the outgoing direction) In the event that the level of the telecommunications area identifier is to be raised to a higher level, the coded telecommunications area identifier is set to this level and a part of the outgoing address is added according to Table 1. This corresponds to a conversion of the addressing format of Block 9 to the addressing format of block 12 ,

Transformation T9: (usually for addresses in the outgoing direction) In the event that the address is in the private numbering plan and the level of the telecommunications area identifier is to be raised to a higher level, the outgoing address is supplemented as shown in Table 1. This corresponds to a conversion of the addressing format of Block 10 on the addressing format of the block 13 ,

The both examples above for the transformations T8 and T9 show an increase of the coded telecommunications area identifier from a lower to a higher one Level. In contrast, but is also a lowering of the coded telecommunications area identifier from a higher possible to a lower level, provided a higher level regional identifier for incoming addresses belongs to the region of its own telecommunications system, or for outgoing Addresses to the region of the foreign telecommunications system. This will be the regional identifier with that of the own / foreign equipment data compared. For example, for a telecommunications system telephone number in a telecommunications system in Germany the country code "49" will be deleted, without making the address ambiguous. This is why made the address within the system always at the lowest possible to bring a clear level.

In the following two examples of transformations T8, T9 the own country code "49" and the own level 1 regional code "2".

Transformation T8: (normally for addresses in the incoming direction) If the address in the ISDN numbering plan is present, the coded telecommunications area identifier can be lowered from the "International" level to the "National" level by deleting the corresponding country code from the address according to Table 1 , This corresponds to a conversion of the addressing format of Block 9 to the addressing format of block 12 , Similarly, a reduction from "national" to "regional" is possible.

Transformation T9: (usually for addresses in the incoming direction) In the event that the Address in the private numbering plan and is to be lowered from the higher level of the telecommunications area identifier "Level 1" to the lower level of the telecommunications area identifier "Local" is deleted according to Table 1, the corresponding part of the address. This corresponds to a conversion of the addressing format of Block 10 to the addressing format of block 13 , Likewise, a reduction from "Level 2" to "Level 1" is possible.

transformations T10, T11, T12: Transformations T10, T11 and T12 are used to insert parts of telecommunication system telephone numbers into addresses. there For outgoing addresses, the telecommunications system telephone number is used the own telecommunications system inserted into the address. To this The purpose is the own telecommunications system telephone number according to the table 1 used. For the Case that the internal address (direct dial number) to outside the telecommunications equipment or the domain in which it is valid, has to be sent, it must be set to the explicit format by building the telecommunications equipment telephone number before that becomes.

In the case where the ISDN numbering plan is preferred in the device data according to Table 6, as shown in the example below, the telecommunications system telephone number must be inserted according to the ISDN numbering plan. For this purpose, Table 4 shows to which level the address is added. This corresponds to a conversion of the addressing format of Block 11 to the addressing format of block 12 ,

If, according to the facility data in Table 6, the private numbering plan for the outgoing address is preferred, the own telecommunications equipment number must be inserted according to the private numbering plan. This corresponds to a conversion of the addressing format of Block 11 to the addressing format of block 13 ,

Farther can the transforms T10, T11 and T12 are used on incoming addresses become the telecommunications system telephone number of the foreign telecommunication system to insert in the address. For this purpose, the telecommunications system telephone number of the foreign telecommunications system is off taken from Table 1. If an incoming internal address (direct dial number) ambiguous in their own telecommunications system or in their own domain is, it must be made clear. This could be the case, for example be when the foreign telecommunications equipment is unable to to signal the complete ISDN address but only the internal direct dial number. Then it is necessary to arrive Address around the telecommunication system telephone number of the connected strangers Complement telecommunications system. For this purpose, first tries to translate the address into the explicit format by the previously described transformations T1, T2, T4 or T5 are performed. Only for the case that this is not possible is (transformation T3), the telecommunications system call number inserted, if this is included in the facility data according to Table 1.

In the following two examples has the connected telecommunications system the telecommunications system number 69-7505 in the ISDN numbering plan and 9021 in the private numbering plan. In the two examples can be seen that the incoming address is not unique and by adding the foreign telecommunications system number in the respective numbering plan is made clear.

The two examples correspond to a conversion of the addressing format of Block 11 in the addressing format of block 12 or from block 13 ,

Transformations T13, T14: In the event that an explicit address is to be converted into an implicit address, the information of the coded telecommunications area identifier must be converted into one or more additional digits before the address. In the following example, a conversion of the addressing format of block takes place for this purpose 12 to the addressing format of block 14 ,

The Assignment of the TON prefix to the telecommunications area identifier in ISDN or private Numbering plan is shown in Table 2. For outgoing Addresses to the foreign telecommunications system must be from the setup data This table will be the part of the foreign telecommunications system. For incoming Addresses must be the part of their own telecommunications system.

Transformations T15, T16: If an explicit address is to be converted to an implicit address, the information in the coded numbering plan identifier must be converted to one or more additional digits before the address. The following example shows a conversion of the addressing format of Block 14 to the addressing format of block 16 , It can be seen that the NPI prefix is set before the address for the ISDN numbering plan "0." In order that the foreign telecommunications system can also process this prefix for an outgoing address, this must be taken from the configuration data of the foreign telecommunications system according to Table 3 become.

The Converting the coded numbering plan identifier into the NPI prefix can only then be executed if previously the coded telecommunications area identifier in the TON prefix was converted.

The assignment of the NPI prefixes to the coded numbering plan identifiers according to the ISDN or private numbering plan is shown in Table 3. For outgoing addresses to the foreign telecommunications system must be taken from this table, the part of the foreign telecommunications system. For incoming addresses, the prefix must be chosen according to your own telecommunications system.
