215 WABE - Digit Analysis

"Digit analysis" refers to the assignment of a digit analysis result (DAR) to a dialed digit sequence or code. This assignment is dependent on the call progress state (CPS) and digit analysis group or dial plan (DPLN).

In general it is recommended to allocate for each DAR only closed station number ranges (e.g. CD=3000&&3699 for DAR=STN), in this case the internal used dialling plan tree is very short, uses less memory space und works performant. The dialling plan tree will be then built-on until the 2. digit of the station number, because the following 3. and 4. digit are all available in the DAR, this means only a few number of dialplan blocks is needed. When now one station number (e.g. "DEL-WABE:CD,3111;") is deleted from this station number range, then the AMO WABE must extend the dialling plan tree in general by the 3. digit and for the station number range 3110 - 3119 also by the 4. digit. Note, additional memory space in the form of dialplan blocks is therfore necessary to remove the station number 3111 from dialling plan! Please pay attention during creation of a dialling number plan, as more as a station number range for a DAR is subdivided also more increases the need of dialplan blocks to perform a correct digit analysis.

There are two types of digit analysis result: DARs with a specific dialing outcome (e.g. ’STN’; dialing result is station number), and DARs whose dialing outcome must be defined in other AMOs (e.g. ’CO’; the trunk routes which can be accessed via this DAR are defined with the AMO RICHT).
The DARs NETW, NETWFAX and NETWDTE have a special status; for these DARs
the AMO WABE enters supplementary information (parameter DESTNO) as well as the digit analysis result. In addition, information entered with the AMO RICHT for the NETRTE DAR is relevant for call processing purposes.
The DAR STN in HICOM networks has a special status very similar to the DAR NETW. If an STN is in another node, it is added in the local node with the parameter DESTNO. Then it is used just like NETW. Every DAR STN is only permissible independently of DPLN, i.e. without specifying the parameter DPLN.

DAR NETRTE also has a special position: Just as with STN, it must be assigned independently of DPLN groups and only for CPS=0, so that it cannot be directly dialed.

Associated digit analysis results are combined into a digit analysis result pair.

Some digit analysis result pairs are viable only if both parts are assigned (e.g. activate call hunt group - deactivate call hunt group). An expanded input is provided so that such pairs can be handled together if changes are made in the DPLN table. Parameters exist for the partner DAR in the ADD and DELETE commands (CD2, CPS2 & 2). The parameter DPLN applies to both DARs of a pair. In the DELETE command with TYPE=CD, the partner DAR must always be explicitly included. This is done automatically in the ADD command (default value CHECK=ALL), even if CHECK=PART is specified. By specifying CHECK=N, the user is able to specifically exclude the partner DAR. This can save time in some cases; however, the user must remember to create a new partner DAR with the appropriate command. The REGENERATE command generates an ADD command batch with CHECK=N in each case (i.e. with less parameters). This speeds up a generate command sequence because of less parameter checks.

When the feature VNR is activated (VNR switch in ZANDE is set), DPLN dependent configuration must be allowed for DAR=STN and forbidden for DAR=OWNNODE. Both station and node access code can not be deleted as long as at least one subscriber is configured for it, a delete command is rejected with the existing F11 error message.The destination number associated with an access code leading to DAR=STN can be configured individually for different virtual nodes in CHANGE-WABE. Therefore the CD parameter allows up to 12 digits representing a the station number with node access code.The CD parameter in ADD, DELETE, DISPLAY or REGENERATE remains up 6 digit long.When the feature is activated, the subscriber output has to be changed too. Together with the VNR feature that grouping makes no longer sense, because the same number can be configured in different destination nodes for the individual virtual nodes. In many cases it will also be configured for some of the virtual nodes and reserved for the other. Therefore the output for DAR=STN will show no extra lines with reservation flag or destination number. This information is displayed in individual blocks for each virtual node together with the associated DAR=OWNNODE entries.

The DARs APIN1 to APIN15 (activate personal identification number for copin1 to copin15) and the DAR DPIN (deactivate personal identification number) have a special status within the digit analysis result pairs. These DARs are practicable only in pairs, but have to be added with single AMO calls. This is because there is only 1 deactivation DAR for the 15 activation DARs. Independent of DPLN or for a specific DPLN, if one of the DARs APIN1 to APIN15 exists, the user is responsible for ensuring that the DAR DPIN exists and vice versa.

In addition, some DARs belong to specific DAR sequences, in other words, within the specific DPLN group and CD category a predecessor DAR must be entered before the successor DAR in the sequence can be added. The sequence must also be adhered to when deleting. The sequence may be ignored if CHECK=N is specified.

Associated pairs for simultaneous processing are listed in Table 49 and pairs for sequential processing in Table 50. Digit analysis results AFWDVCE, ADND and ACOSX can also be used as ’feature toggling’ digit analysis results. Thus, in the case of these digit analysis results, it is no longer necessary to handle them in pairs with the corresponding deactivation digit analysis results.
Simultaneous updating of the TWABE tables is not carried out automatically. In order to speed up call processing, it is recommended that the desired data be imported with the AMO TWABE (e.g. all CDs to DAR=STN).

There are more features connected to special DARs, e.g. there are only decimal digits allowed with DAR STN or FLASHCD, also only 1 digit is allowed for DAR FLASHCD.

Call forwarding for DSS1 terminals

The range of validity for the DARs AFWDREM, DFWDREM and FWDREM is defined by AMO WABE as a supplementary information to the DARs according to the parameters CFREMVAR and CFREMSE. Meaningful combinations of these parameters are listed in the following table (not checked by the AMO):

DAR for devices with dial pulse only option

If CD assigned to the DAR in question should also be available to terminals which only support the dial pulse option (previously known as pulse dialing), but contains special characters (SC),

•

the parameter must be specified (except when CHECK=PART/N).

•

the parameter 2 must be specified in the case of DAR pairs (except when CHECK=PART/N).

•

neither the parameter nor 2 may be specified in the case of a CPS expansion.

Networks:

All STN codes in a network are stored with the DAR STN in the tables of each node. To the external STNs (these are the STNs in other nodes) the DESTNO is assigned with a separate CHANGE action.
With DAR NETW now only those codes are stored, that must be reached from all nodes of the network.
If an external STN becomes an internal one, first the DESTNO must be changed to 0.

The station number (CD) of DAR OWNNODE is used for feature networking route optimization of the AMO ZAND TYPE=ALLDATA, parameter NODECD. Before changing or deleting this digit code, the relating information has to be changed or deleted with the AMO ZAND.

The ISDN dial plan has been implemented via QSIG since Hicom 300 E V1.0 and V3.5. With this dial plan it is possible to image the public dial plan on a private network.

If a Hicom system is connected to or in a network that operates using the ISDN dial plan, the network access code to the ISDN network must be created with DAR=TIE (tie-trunk) instead of DAR=CO (attention must also be paid here to the CPS-dependent creation of the DAR TIE). There is no longer a CO DAR there as only the LCR decides whether the call is routed to a real public exchange or to a carrier.

Use of the ISDN dial plan for access to systems smaller than EV1.0 / V3.5 is not allowed in the private network.

Range inputs:

If a job with range inputs cannot be carried out completely, only the permissible entries are made in the DPLN table. The dominant parameter is the station number or digit code (CD). Error messages are generated for the entries that cannot be executed.

CPS range

Call progress states (CPS) cannot be specified as ranges. However, it is possible not to specify the parameter CPS, in which case all CPSs permitted for the associated digit analysis results are intended. The permitted values are defined in a table that cannot be changed by administration and maintenance.
The DISP-WABE:TYPE=CPS command allows the user to output either the complete table or a specific row (DAR=<param>).

Note for Optiset terminals:

The function of some digit analysis results can be called via the Optiset menu. This function is only displayed in the Optiset menu if at least one CD was set up for an Optiset-relevant DAR. Optiset-relevant digit analysis results are required to be added with full CPS range, i.e. with all CPSs permitted for the associated digit analysis result. This is achieved by entering no value for the CPS value. The CPS range permitted for the associated digit analysis result is stored in a read only table in the database of the system. This table, i.e. the CPS amount of digit analysis results, can be displayed using DISPLAY-WABE:TYPE=CPS,[DAR=<param>];.

Table 52

Optiset-relevant DARs to be created without CPS specification

Always create without CPS specification

If the CPS range permitted for a digit analysis result has been enlarged, e.g. caused by a change request, all configured access codes for that digit analysis result must be expanded to fit the new CPS range. This can be done using the command ADD-WABE with CHECK=N. This action must be called for each access code assigned to the respective digit analysis result (see example below). If the additional new call progress states are specified in the ADD command, the advisory message H07 is displayed and the action is performed using the full new CPS range to ensure that the CPS expansion really fits the full CPS range.

Example:

Optiset-relevant digit analysis result APIN1 has been enlarged from CPS 5 to 5&8&9&17:

DIS-WABE:TYPE=GEN,DPLN=0&&63,DAR=APIN1;

------------------------------------------------------------------------------

| DIGIT INTERPRETATION VALID FOR ALL DIAL PLANS |

| APIN1 |. ....* ..**. ..... .*... ..|

-----------------------------------------

Expand the access codes *81 and 881 assigned to the respective digit analysis result APIN1 to the full CPS range using the command ADD-WABE with CHECK=N (one command, giving the new, additional CPS values - therefore H07 - and one command without parameter CPS):

ADD-WABE:CD=881,CPS=8&9&17,DAR=APIN1,CHECK=N;

H07: OPTISET-RELEVANT DAR MUST ALWAYS HAVE FULL CPS SET.

- PARAMETER CPS WILL BE IGNORED.

- ACTION CONTINUES WITH FULL CPS SET.

Note for output interruption:

The output of long lists can be canceled using I/O interrupt. In the case of the actions DISPLAY and REGENERATE, the output can be canceled immediately. In the case of ADD, DELETE and CHANGE, the output of the error messages can be canceled. Cancellation is not carried out until the dominant parameter (CD) has been tested completely, i.e. error messages can still be output before the AMO is canceled.

Note for 7/8-digit codes:

This feature can not be activated together with the VNR feature.The code is converted to a 6-digit code within the dial plan.

In the case of a 7/8-digit code, the last 4 digits define the code base and the 3-4 digits ahead define the office code. The office code is assigned to DAR OWNNODE. A 2-digit alternative reference number (ARN) is assigned to the office code. The ARN is stored in the additional data of the DAR OWNNODE.

The 4-digit code base is prefixed with the 2-digit alternative reference number and results in a 6-digit alternative code. The 6-digit alternative code is assigned to the target DAR.

More than one office code can be assigned to the same ARN. This enables the access of a destination using several codes. However, only one office code can be defined for display. Using a CHANGE command, the office code used for the display can be specifically defined.

The feature was not developed to display the own 7/8 digits number on the IDLE devices.

If the real number configured by SBCSU is not desired on IDLE display, there is the option to hide it by:

ZAND:ALLDATA2 parameter DSPOWNNO for optiset, optipoint, Openstage 15/20/30, and by ZANDE:OPTFEA,708 for Openstage 40/60/80, DPIP, CP (device restart required).

Figure 85

Example for a 7- and a 8-digit subscriber number:

In special cases, the code base can be defined with less than 3 digits, the office code even with less than 3 digits. However, the ARN always consists of 2 digits.
