7.15 Euro-ISDN Features (Not for U.S.)

Definition

The Hicom 150 E Office system complies with the DSS1 standard, which specifies the requirements for the uniform communication structure standardized by ETSI throughout Europe.

Euro-ISDN provides users with various features that can be activated either permanently in the trunk or by means of a procedure. It is not necessary to configure the feature specifically.

The features available with Euro-ISDN and Hicom 150 E Office are listed below.

7.15.3 Default Station Number Instead of Multiple Subscriber Number (MSN)

Definition

This feature was created to increase security and to settle call charges (in a hotel environment, for example). Previously, the system was able to automatically configure each valid MSN. This meant that the settlement of call charges and call detail recording took place under a number which the CS operator did not necessarily enter.
In addition to dialing an MSN, users now have the option of dialing the internal default station number instead.
Below is a brief explanation:
The system assigns a sequential default number to each port, and therefore each telephone, in ascending order (starting with 101 in the OfficePro system). This means that each ISDN S0 bus is assigned a default number. For an S0 port terminal adapter, the default number is identical to the number of the logical port in the secondary optiset E telephone. The system assigns valid station numbers by default, although they can be changed with Hicom Assistant E. Every station number is always assigned to one logical port number.
The default numbers can be used as follows:

Outgoing call setup:
The system sets up the call using the default number, regardless of the MSN sent by a telephone or application. Customers are billed on the basis of the default number (in a hotel environment, this can be the room number), combined with a fixed number combination.
Incoming call setup:
When a customer equates the MSN of an application (which may be installed on a notebook computer and connected to the hotel telephone network via an S0 terminal adapter) with the default number of a hotel room (combined with a fixed number combination), callers can reach the PC directly from the outside by direct inward dialing.

AOC-S - Advice of charges at call setup
Call charge display on the telephone is the same as for AOC-D.
The charges are not displayed if the call was not fully set up or if Hicom 150 E Office is unable to evaluate the call detail information of a service provider.
AOC-D - Advice of charges during the call.
AOC-E - Advice of charges at the end of the call.

7.15.9 Call Forwarding (CF)

Definition

There are three different call forwarding types:

Chaining call forwarding unconditional
Users can activate variable call forwarding or call forwarding preset by key programming (unconditional, immediate) for the following call types:
Incoming internal calls only
Incoming external calls only
All calls
This is possible even if the same station is already set as a forwarding destination or if the forwarding destination has already activated call forwarding.
The message "Chaining invalid" no longer appears when you enter a second call forwarding destination during programming.
When a user forwards a dialed party to a station which already activated unconditional, immediate call forwarding to another station, the system monitors the number of call forwarding operations allowed. A preprogrammed counter limits the number of call forwarding operations to a total of 5.
The following example clarifies this procedure:
Stn A activated call forwarding to stn B: 1. CFU
Stn B activated call forwarding to stn C: 2. CFU
Stn C activated call forwarding to stn D: 3. CFU
Stn D activated call forwarding to stn E: 4. CFU
Stn E activated call forwarding to stn F: 5. CFU
Stn F activated call forwarding to stn G: 6. CFU (not possible)
If stn X calls stn A, the call reaches stn F, not stn G.
The system forwards the counters with CFU, but not with CFB or CFNR.
Call forwarding busy (CFB))
Same as CFU but only if the line is busy.
Call forwarding no reply (CFNR))
Same as CFU, but only if the call is not answered within 15 seconds (time is configurable).

Use call management to define the lines for busy and no reply.

CF 
Call forwarding is always executed for the first basic access, that is the first S0 port must also be available in the system. 
Internal to S0 
Internal stations support CFU only (to prevent conflicts with call management). 

7.15.10 External Call Forwarding

Definition

Any user who has an MSN as a DID number can activate and deactivate external call forwarding for this MSN, provided that the user is authorized to use external call forwarding. A total of 10 multiple subscriber numbers can be forwarded.

If you have assigned an MSN to a subscriber group, any member of the group can activate and deactivate external call forwarding for this MSN.

Users can enter only one forwarding destination per MSN.

There are three different versions of the feature:

Call forwarding unconditional (CFU)
The carrier forwards all calls to this MSN directly, regardless of the MSN status.
Call forwarding busy (CFB)
Calls are forwarded only if the MSN dialed is busy.
Call forwarding no reply (CFNR)
Calls are forwarded only if the destination does not answer the incoming call within a preset period of time, such as 15 seconds (time is configurable).

7.15.11 Call Deflection (CD)

Definition

If a station has activated external call forwarding, Hicom 150 E Office attempts to forward calls to the trunk using this feature. In this case, the new call destination and the station number of the forwarding station are provided to the trunk in the call deflection activation message when the call arrives. If external call forwarding by call deflection is not possible, the system handles call forwarding.

Definition

This feature makes it possible to identify unwanted callers. The feature is activated in the public network, and the caller's station number and name are also stored in the public network. With each incoming call, the release of the connection to the called station is delayed for a specific period of time after the caller hangs up, enabling the called station to activate this feature. Release is delayed only if the feature has been requested from the carrier or facility provider.

UUS1: Information is exchanged in control messages for connection setup and during connection release.
USS2: Information is exchanged during the ringing phase. The number of messages is limited to two per trunk group. USS2 is available for telecommunications ports only.
USS3: Information is exchanged during the active state of a connection.

7.15.22 Programming National and International Codes for Outgoing Calls

Definition

The caller's station number, including the trunk access code (0, for example), the national prefix (0, for example) or the international prefix (00, for example), appears in the optiset E telephone display, the caller list, and dialing aids (such as Smartset).

Carriers are reached by dialing a separate national prefix (1 digit) or international prefix (2 digits). If a Hicom 150 E Office system provides access to more than one carrier (separate port or shared port), it is not possible to determine the carrier from which incoming calls arrive.

To represent a prefix, this feature enables you to configure the national and international access codes (national and international prefixes). A number between 0 and 9 can be used as the values for the programmable digits.

This allows calls to be answered with the help of caller lists and Smartset even when carriers are used. The existing prefixes are also used for the carriers.
