28 • ISDN interface configuration

Introduction

This chapter provides an overview of ISDN interfaces, and the tasks involved in their configuration. This chap-
ter does not explain the basic configuration steps equal to all CS interfaces. Information about basic interface
configuration can be found in the general chapter about CS interface configuration (see chapter 27,
face configuration" on page 315)
An ISDN interface represents the connection of an ISDN signaling channel to the call control of SmartWare.
It encapsulates the ISDN layer 3 protocol of an ISDN port's D-channel, allows incoming and outgoing calls on
this port, controls its B-channels and provides a set of services.
There is a one-to-one relation between the port and the interface: Only one port can bind to an existing inter-
face, and there must be a port that binds to the interface for the interface to become functional (see
An ISDN interface can encapsulate user and network side of the following protocols: DSS1, NI2, NTT. The
settings are automatically taken from the port that binds to the interface, and changes on the port are automat-
ically reflected on the interface. See chapter 35,
ISDN interface configuration task list
This section describes the configuration tasks for ISDN interfaces. There are no mandatory configurations on
ISDN interfaces, because all protocol relevant settings are inherited from the port that binds to the interface.
The settings on the interface are those of basic CS interface configuration, as well as settings for interoperabil-
ity and supplementary services:
• Configuring DTMF dialing (optional)
• Using an alternate PSTN profile (optional)
Configuring DTMF dialing (optional)
Most ISDN terminals support two modes of call setup: En-bloc dialing and overlap dialing. En-bloc dialing
transports the full called party information in the first SETUP message from the terminal. This means that the
user must dial the number before going off-hook. Overlap dialing transports the called-party number digit by
digit, after the first SETUP message, which contains no called-party information at all. Combinations between
en-bloc and overlap dialing are possible.
