Two Switch Scenario
NCAUUI allows PRI users located on different switches to communicate by
means of User Information messages without setting up a circuit-switched
connection.
For the PRI interface, the user-to-user signaling messages are carried over
the D-channel. For the SS7 interface, the user-to-user signaling messages
are carried over the SS7 signaling link using SCCP.
Billing Record should have:
