## Spain – IBERCOM Indicator

## Definition

The IBERCOM user services are special public network functions which will be provided by TELEFONICA to subscribed customers in Spain.

The IBERCOM user services are comparable to VPN (Virtual Private Network) functions provided by the public network.

The IBERCOM indicator is a special information element in the call-setup message of outgoing calls on an ISDN interface in Spain and indicates to the public network that the calling party is an IBERCOM service subscriber and that the call shall be handled as an IBERCOM network call.

## Use

The IBERCOM indicator function was developed for Spain, and is only available in the related specific national ISDN protocol.

The function is only available to customers having subscribed to the IBERCOM service, and makes possible to access the provided services such as special call tariffs.

## Operation

For the end user the external call handling or the CN call handling via the IBERCOM network, is the same as the call handling via the ordinary public network.

From the ISDN protocol’s point of view there is a difference in the form of the national specific IBERCOM indicator. The indicator contains the following parameters.

- Call class
- Charging type

The values of the parameters depends on the programming.

### Call class

This parameter defines whether the call is handled as an interuser or an intrauser IBERCOM call.

- Interuser call

- An external call terminated ouside the IBERCOM network or a call within the IBERCOM network whereby the called and calling parties are belonging to different (CN) companies.

- Intrauser call

- An external call within the IBERCOM network whereby called and calling parties are belonging to the same (CN) company or organisation.

### Charging type

This parameter defines whether individual or group charging shall be performed for the call.

- Individual charging

- The call will be charged to the individual extension.

- Group charging

- The call will be charged at system (PBX) level.

## Capacity

Not applicable

## Limitations

The IBERCOM indicator can only be used in conjunction with the ISDN protocol for Spain.

## Programming

0150 |  | Individual charging?

The following commands are only accessible via BMS/RASC:

1911 |  | Network signalling protocol

9104 |  | Call Class

1036 |  | Type of IBERCOM netw. conn.

## Equipment

The following trunk boards are supporting the IBERCOM functionality: BTU-D with ISDN Prom set, BTU-B, MFU.

If the IBERCOM indicator is used in conjunction with CN calls (command 9104), the connected FECU on the CPU-D4 must have one of the following Indexes:

- /2, /3, /4, /5, /7, /8, /9, /10
- /6 (only valid for SW Releases higher than R10)
