# Regions

A region is a set of regionally dependent settings. Region 1 is the standard region. If the communication server and terminals/phones are at the same location you will not require any further regions. However, if you have configured remote terminals/phones or if you have an AIN with remote satellites you can define and configure further specific regions here.

## Regions in AIN

Each node is necessarily allocated an AIN area. After the first start this is the AIN region 1. This area is permanently allocated to the Master. After the first start that area is an area. If a satellite is situated in an area that requires other settings, you need to create a new AIN area, modify the settings and allocate the new AIN area to the node.

Country-related settings that are the same throughout the AIN are taken from the settings of AIN region 1.

Note:

Make sure the correct sales channel is set on the EIM card already before the configuration. You can subsequently change the sales channel if you need to. However this involves a system first-start and the licences have to be re-enabled (licences depend on the sales channel).

Table 1. Allocation examples of AIN areas
Situation | Allocation
All the nodes are in the same area | Each node is allocated an AIN region 1 (default value)
The Master is located in Spain, with a satellite in Portugal | Spain is selected as the country for the AIN region 1. For the satellite a new AIN region is created; Portugal is selected as the country and allocated to the satellite node. Note: The sales channel setting on the EIM card must match the country of the AIN area (see earlier remark).
The Master in Spain is located on the border with France and has a direct exchange line circuit with a French provider | AIN region 1 determines the settings for the node. A new AIN area is created for the trunk group with the French exchange line circuit; France is selected as the country and allocated to the trunk group.

## Region-related settings

Table 2. Regions
Parameter | Explanation
Region | Reference number for the region.
Name | Name of the region
Country | The values for the country-related, non-settable parameters are determined when you chose a country. After the first start the country of the area 1 corresponds to the country stored on the EIM card. Note: The Country setting must match the country of the sales channel set on the EIM card as a number of county-related system parameters are determined by the EIM card, not the AIN area. Example: Congestion tone detection of an analogue network interface.
Country code | The national destination code has to be selected to be able to set up a connection from one region to another within a particular country. Enter the code for your own region here. (Example for the Berlin region: 30).

Table 3. Time zone
Parameter | Explanation
Time zone shift | +/- -deviation from the master time.
Master time | (Display only): The communication server is the master in an AIN.
Time synchronisation via ISDN network | Time synchronisation is made via ISDN exchange access over the public telephone network. Note: Time synchronisation via NTP time server must not be activated at the same time.
Mitel SIP phone time zone | For remote Mitel SIP phones

Table 4. Own local prefixes
Parameter | Explanation
International prefix | The international prefix has to be selected so an international connection can be set up from one particular country. Enter the prefix of your own country here. (Example for Germany: 00)
Country code | The country code has to be selected so an international connection can be set up in one particular country. Enter the code for your own country here. (Example for Germany: 49)
National prefix | The national prefix has to be selected to be able to set up a connection from one region to another within a particular country. Enter the prefix of your own country here. (Example for Germany: 0)
National destination code | The national destination code has to be selected to be able to set up a connection from one region to another within a particular country. Enter the code for your own region here. (Example for the Berlin region: 30).
Note: In some countries the national prefix and the national destination code can also be dialled in the system's own region (e.g. in Germany) or must be dialled as mandatory (e.g. in Switzerland). In these countries these fields can be or must be left blank.

Table 5. Call logging
Parameter | Explanation
Charge value | Enter here the multiplier factor used in analogue network interfaces to convert the charge pulses sent by the provider to the current pulse value.
Minimum call charge for cost centre (OCL) | Outgoing calls by means of cost centre selection will be output as of the charge value defined here.
Minimum call charge for private calls (OCL) | Outgoing calls by means of private exchange access will be output as of the charge value defined here.
Minimum call charge for business calls (OCL) | Outgoing calls by means of business exchange access will be output as of the charge value defined here.
Minimum call charge for room calls (OCL) | Outgoing calls by means of business exchange access will be output as of the charge value defined here.
Round up | Increment of the rounding-off levels. Rounds a charge off to the next level. Example: If set to 0.1 (standard), then the charge is rounded off from 1.23 to 1.3. If set to 0.2, then the charge is rounded off from 1.23 to 1.4.
Exchange rate | Enter here the current exchange rate if you wish to administer the call charges in a currency other than the one used by the provider for his call charge information in digital network interface.

Table 6. Loop break signalling for terminals
Parameter | Explanation
Flash maximum | Maximum time in milliseconds at which the terminal interprets a loop break as a control character (Flash).
Flash minimum | Minimum time in milliseconds at which the terminal interprets a loop break as a control character (Flash).
Disconnect from | Minimum time in milliseconds at which the terminal interprets a loop break as a release signal (go on-hook).

Table 7. Loop break signalling exchange
Parameter | Explanation
Flash (ms) | Time in milliseconds for the way in which a flash signal (alerting signal) is signalled to the exchange.
Ratio | Selecting the ratio. This parameter is significant only for analogue exchange connections using pulse dialling.
Interdigit time | Interdigit time in milliseconds. This parameter is significant only for analogue exchange connections using pulse dialling.

Table 8. CLIP with analogue terminals
Parameter | Explanation
Alerting signal type | There are different methods for transmitting CLIP data on analogue terminals. An alerting signal is needed to detect CLIPs. No alerting signal: Data transmission takes place between the first and second ring signal. The first ring signal is used as an alerting signal. Ring pulse: Data transmission takes place before the first ring signal. A ring pulse is used as an alerting signal. Not defined: No data is detected.

## Other region-related parameters

For many parameters there is already the possibility of configuring several variants without using AIN areas and to allocate them as required. This can also be used to configure regional variants.

The table below lists the main parameters for which values with different regional settings are appropriate and which are not set using the AIN areas.
