Introduction

This chapter describes the configuration of the Q.921 and Q.931 protocol and how to bind the ISDN proto-
col to an application like the Call Control. To get an overview of the ISDN protocol and the layered configura-
tion model of SmartWare, please see Chapter 18,
supposed, the lower layer on which ISDN will be setup is correctly configured. If ISDN has to run on a TDM
port like BRI or PRI, please see Chapter 17,

ISDN configuration task list
Configuring ISDN typically consists of the following tasks:
• Enter Q.921 configuration mode
• Configuring Q.921 parameters
• Configuring Q.921 encapsulation
• Enter Q.931 configuration mode
• Configuring Q.931 parameters
• Configuring Q.931 encapsulation
Enter Q.921 configuration mode
Normally, Q.921 is running as ISDN Layer 2 protocol on a BRI or PRI port. But it is also possible another
protocol is using Q.921 as its next encapsulation step an then Q.921 will not be configured out of a port con-
text. That means, Q.921 encapsulation can be configured in different configuration modes. For this reason, the
command description below refers to the configuration mode in which Q.921 can be enabled by setting the
encapsulation to 'q921'. This configuration mode is called here 'base-mode' but it is only an alias for the real
mode. Once encapsulation q921 has been configured, the Q.921 configuration mode can be entered.
Mode: base-mode
Step
1
node(base-mode)]#[no] encapsulation
q921
2
node(base-mode)]#q921
Configuring Q.921 parameters
This chapter provides an overview of the Q.921 configuration parameters, their syntax and possible restric-
tions. In case of ISDN, Q.921 settings apply to both BRI and PRI ports. They are defined in the q921 mode.
To use Q921, the lower layer encapsulation must be set to q921.
