7Data service
This Chapter deals with outgoing and incoming data service connections. It
looks at types of data services, the configuration of data service destination
tables, and how data services are routed in the private leased-line network.
This section also deals with user-to-user signalling and the fax service on a
CPU2 applications card (Aastra 470 only).
7. 1 Overview
Outgoing data-service connections are set up and routed in a similar way to call
connections. This also applies in a private leased-line network.
Incoming data-service connections are routed via data-service destination tables.
To route a call at a gateway or transit PINX on into the private leased-line network, a
PISN user is entered as the data service destination (see "Routing in the private
leased-line network", page 280).
Internal data-service connections are also routed via the data-service destination
tables (see "Routing to a destination in the data-service destination table",
page 277).
"User-to-user signalling (UUS)", page 282 offers the possibility of exchanging data
during the connection setup and disconnection phases.
Aastra Intelligent Net:
In an AIN incoming data service connections are possible only on the
Master and only if the Master is connected to the public network. Data
service connections are not possible within an AIN (via IP from node to
node).
