Central Dial In

1 DefinitionThe functions of the feature Central Dial In to GeoCENTREX Business Group allowspecific calling subscribers to use the GeoCENTREX internal directory number plan forcalls to both local and external destinations of the GeoCENTREX business group. Ex-ternal destinations are destinations that are not local GeoCENTREX subscribers in thesame network node and in the same local GeoCENTREX group as the GeoCENTREXgroup with the feature "central dial in".

In addition to using the number plan, calling subscribers can use GeoCENTREX-specif-ic features (by dialing digits) that are included in the number plan of the GeoCENTREXgroup with central dial in (see also chapter 2):

The feature is divided into three independent functions (see chapter 2):• Dial In via a GeoCENTREX group directory number (CDI)• Dial In for virtual Centrex mobile and public subscribers of other networks (CDI-

AUTH)• Dial In for Satellite Centrex group subscribers (CDISATPE)

All individual functions can be used independently of each other and should not be bringin together.

Operator benefits– With this service, subscribers of other networks (including mobile networks) or of

other operators with their own business groups can be integrated.– The GeoCENTREX business group features can be offered to Centrex subscribers

from non-EWSD network nodes.– Public subscribers can be offered the use of the GeoCENTREX-specific call charg-

ing as follows:For the call section from the GeoCENTREX group with central dial in to the final des-tination, call charges within this GeoCENTREX group are billed to this GeoCENTR-EX group. Public subscribers benefit indirectly from the fact that they are notcharged for this call section.

Subscriber benefits– Mobile subscribers or public network subscribers without GeoCENTREX functional-

ity can use the GeoCENTREX business group features.– Subscribers connected to network nodes with restricted CENTREX functionality

(satellite Centrex subscribers) can use the GeoCENTREX business group features– Company members and company customers can make calls throughout the network

at the company’s call charge rates.– The cost of calls can be cut by using the GeoCENTREX-specific call charging.

Availability

iNote on making directory number plans:GeoCENTREX access codes that are to be dialed after central dial in may only consistof decadic digits.

Use and effect

The calling subscriber uses the feature functions of Central Dial In, see also Feature au-thorization.

Interaction

For interaction with other features, see Feature Interactions.

Interactions of the individual functions (CDI, CDIAUTH, CDISATPE)• Calls of authenticated subscribers:

Authenticated subscribers dial into their GeoCENTREX business group. To reachCentrex subscribers in satellite groups of the same business group, authenticatedsubscribers then have to dial the group dialing code of the satellite group and theinternal number of the subscriber. To reach Centrex subscribers in satellite groupsof other business groups, authenticated subscribers have to dial the access code forthe public network and the subscriber's public number (like a public call).

• Calls to authenticated subscribers:Authenticated subscribers are linked in a CENTREX group of their GeoCENTREXbusiness group via a remote internal directory number (CENTREX directory numberwith CDIAUTH=YES).In addition to this, authenticated subscribers can also be reached by any subscribervia the GeoCENTREX group in which they are authenticated, even if this group doesnot have the function CDI or CDISATPE

• Calls to subscribers in a satellite group:Subscribers in the public network can reach the Centrex subscribers of a satellitegroup via an (intermediate) GeoCENTREX group with CDI, as long as both Centrexgroups belong to the same GeoCENTREX business group.

2 Mode of operationWith Central Dial In to GeoCENTREX Business Group it is possible for– incoming calls from the mobile network, (CDIAUTH function)– incoming public calls from the fixed network, e.g. subscribers from other operators’

networks who authenticate themselves as belonging to the Centrex group, (CDI-AUTH function)

– incoming calls from satellite Centrex groups that do not have the network-wide pri-vate directory number plan of the business group, (CDISATPE function)

to be handled and charged as a business group-internal call from the central dial-in pointwithin a network-wide business group.– incoming calls from the public network for the purpose of dialing in via one of the

GeoCENTREX group directory numbers or for inexpensive forwarding within thebusiness group (CDI function)

to be charged as a business group-internal call from the central dial-in point within a net-work-wide business group.

For a network-wide business group, it is also possible to define several central dial-inpoints for different local GeoCENTREX groups.

For the feature functions CDI and CDISATPE the central dial-in point is defined via theGeoCENTREX group feature. In the case of the function CDIAUTH the group is as-

A30828-X1150-C201-5-7629 9


Central Dial In

signed the feature indirectly via the numbering plan with the aid of internal directorynumbers that are created with the attribute CDIAUTH.

The fixed network features CCBS and CCNR can only be used with central dial in if thecalled subscriber is located in the same network node as the GeoCENTREX dial-ingroup.

For the directory number display at the destination, appropriate numbers are transmittedin the additional calling party number, among other things. The number of digits that canbe transmitted is limited by the system to 16. If the number of digits is exceeded, no ad-ditional calling party number is transmitted.

ISUP Loop

For calls from subscribers connected to the same network node as the GeoCENTREXdial-in group (in the case of CDI and CDISATPE, authenticated subscribers are, by def-inition, in a different network node) which are not terminated locally in this GeoCENTR-EX group, ISUP loops are necessary for separating the connection sections.

The number of trunks required for ISUP loop depends on the number of dial-in groupsand the volume of their traffic to distant network nodes, and also on the number of sub-scribers connected to the dial-in network node. For dimensioning purposes, the trafficvalues measured for the ISUP loop should be used.

If there is a CDI group and a CDISATPE group in the same network node, the ISUP-LOOP is always looped in.

2.1 Dial In via a GeoCENTREX group directory number (CDI)In the case of local GeoCENTREX groups with the CDI feature, their group directorynumber is used for central entry into GeoCENTREX business groups, which can bespread over several network nodes. Calls via the group directory number are forwardedwithin the business group at GeoCENTREX-specific tariffs.

After the group directory number has been dialed, only GeoCENTREX-specific accesscodes can be dialed:– Internal dialing– Remote dialing– Group dialing– Location dialing

Calls into the public network are not possible. GeoCENTREX-specific access codescan, however, lead to subscribers outside the GeoCENTREX business group, if thesehave been created as remote internal subscribers with the feature CDIAUTH (see chap-ter 2.2).

Call authentication is not necessary. Calls via this dial-in point are treated like externalcalls and can only use the features of the public network, i.e. none of the features withinthe GeoCENTREX group.

If the feature Calling Line Identification Presentation (CLIP) has been created, the direc-tory number of the calling subscriber is displayed to the called subscriber (see alsoTab. 7.1 to Tab. 7.8).

Fig. 2.1 Dial In via master GeoCENTREX group directory number (CDI)

2.2 Dial In for virtual Centrex mobile and public subscribers ofother networks (CDIAUTH)A public or mobile network subscriber is registered in a GeoCENTREX group with cen-tral dial-in point as a virtual member of the business group. This is implemented in thedirectory number plan of the GeoCENTREX group via a remote internal directory num-ber and the public directory number of the group member with the feature CDIAUTH.

The subscriber can dial into his or her GeoCENTREX business group by dialing the pub-lic directory number (GeoCENTREX group directory number, in which the subscriber isauthorized). The calling subscriber is authenticated as a member of the business groupon the basis of the directory number forwarded via the network signaling. The dialed in-formation following the group directory number is evaluated in the private GeoCENTR-EX directory number plan as access code, service code or internal directory number andthen treated as an internal call in the business group. This means that the call is alsosignaled to the destination subscriber as an internal call and, if the feature Calling LineIdentification Presentation (CLIP) has been created, the private number determined onthe basis of the calling directory number is displayed in order to permit inexpensive call-back (see Tab. 7.9 to Tab. 7.12).

Central Dial In

If the result of the evaluation of the dialed information indicates a destination within theGeoCENTREX business group in a different network node, the call is forwarded on thebasis of the group-specific private directory number plan.

Authorized calling subscribers (CDIAUTH) can also reach destinations in the public ormobile network via central dial in to their GeoCENTREX business group.

Certain GeoCENTREX-specific features can be activated and used by means of servicecodes transmitted together with the call:– Call waiting, call-controlled– Subscriber barge-in

Fig. 2.2 Dial In for virtual Centrex mobile and public subscribers of other networks(CDIAUTH)

2.3 Dial In for Satellite Centrex group subscribers (CDISATPE)Satellite Centrex groups are local Centrex groups, usually from other manufacturers (notSiemens, e.g. Alcatel S12), which can signalize the network-wide business group iden-tification (BGID). Satellite Centrex groups can be integrated in a GeoCENTREX busi-ness group via the central dial-in point if they have the same BGID. For this purpose theGeoCENTREX group must be assigned the feature CDISATPE for central dial-in. Also,the numbering plan of the GeoCENTREX group must contain the codes for access to

iIn the case of an unstructured directory number plan within the GeoCENTREX businessgroup, the remote internal directory number for the virtual subscriber has to be createdin all local groups, in order to permit callback (see Tab. 7.16). (Here, the DNDAT of theauthorized subscriber must be entered as NEWCODE, together with the CXDN of theauthorized subscriber).

the network node of the satellite Centrex group and to all the required destinations of theGeoCENTREX business group.

On the basis of the received group directory number (+ access codes) and the internaldirectory number, the call is forwarded within the GeoCENTREX business group.

The group location dialing code (establised out of the group directory number) and theinternal directory number of the calling subscriber are displayed via the central dial-in tothe called subscriber so that he or she can reach the calling subscriber, if the featureCalling Line Identification Presentation (CLIP) has been created (see Tab. 7.17 toTab. 7.22).
