METERING - ISVPN+ CALL SERVER : PRIVATE NETWORKS
Ed. 042/4 Réf. 3EH 21000 BSAA
DATA TRANSMITTED
This paragraph describes the information which is transmitted to the master system by the other sys-
tems in the network; this data is conveyed by the QSIG protocol UUS.
Global data: Node number
This datum (unique value 0 to 127; by default: 255) identifies the system in the network.
Data relative to each communication
- "transmitted" number: number resulting from the NMT conversion of the number dialed after ana-
lysis in the main numbering plan (or NMT conversion of the number received after analysis in the
incoming public call numbering plan); it is thus possible to compare the number sent (to the ARS
table) by the system with the original number dialed.
- charged user: This datum depends on the type of call:
• outgoing call or break-out: caller
• incoming call or break-in: user having answered the call; this user may be different to the called
user (forwarding, call pick-up, etc.)
- transfer: user who is the destination of the transfer
- flags characterizing an ARS call:
- complementary services: This data indicates the services activated in order to carry out the current
call:
• substitution (DISA transit)
• use of the ARS table
• homogenous ISVPN call
- VPN call (Transgroupe for example)
- supplementary network facility: indirect access to an operator
- on-line metering request in the event of break-out
- by MMC-PM5 (Expert View), select: External Lines -> Protocols -> ISVPN Protocol ->
Node Number. This information is only used by the metering application (not used in a tele-
phone context). The node number indicated is the one to which the charged user is connected.
- by MMC-PM5 (Expert View), select: Numbering -> Automatic Routing Selection -> ARS
Table -> Option: Metering:
• forcing onto private network (private): this flag indicates whether an outgoing call has
been rerouted onto leased lines by the ARS.
- overflow: this flag indicates whether the trunk group used for the current call has been ob-
tained after overflow by the ARS.
