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 322)
An ISDN interface represents the connection of an ISDN signaling channel to the call control. It encapsulates
the ISDN layer 3 protocol of an ISDN port's D-channel, allows incoming and outgoing calls on this port, con-
trols 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 ringback tone on ISDN user-side interfaces
•
Configuring call waiting (optional)
•
Disabling call waiting on ISDN DSS1 network interfaces
•
Configuring date/time publishing to terminals (optional)
•
Enabling sending of date and time on ISDN DSS1 network interfaces
•
Defining the 'network-type' in ISDN interfaces
•
ISDN explicit call transfer, SIP REFER transmission
•
