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.
