Data services

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. Other topics include user-to-
user signalling and the transition to the X.25 data network.

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
leased-line network", page
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 233).
Other subjects in this chapter include:
• "User-to-user signalling (UUS)", page 238
• "X.25 in the D channel", page 239
Ascotel® IntelliGate® 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).
