METERING - ISVPN+
ISVPN+ is used for a network of Alcatel OmniPCX Office systems linked together by digital leased lines
with the QSIG-BC protocol.
The principal use of ISVPN+ is for centralized metering.
For all incoming and outgoing calls made within the network, the master system (the one connected
to the public network) gathers the required information and sends it to a centralized metering appli-
cation. The following information is transmitted to the master system:
- outgoing call: all the data presented in the following paragraph is managed at the caller's system
level then transmitted to the master system. The flags characterizing the call are accumulated throu-
gh the different systems during transmission to the master.
- incoming call: the number "transmitted" to the called party and the various flags are generated by
the master system. During the setup of a communication with the called party, the flags characte-
rizing the call are accumulated through the different systems. The number of the charged caller,
the metering node number and the accumulated flags are forwarded to the master system with the
connection message.
