Tone Configuration 265
27 TONE CONFIGURATION
This chapter gives an overview of SmartWare call-progress-tone profiles and tone-set profiles and
describes the tasks involved in their configuration. For detailed information on syntax and usage
guidelines for the commands listed in the Configuration Tasks, refer to Chapter 12, “Profile Tone Set
Mode” or Chapter 11, “Profile Call-Progress-Tone Mode” in the SmartWare
Command Reference
Guide.
This chapter includes the following sections:

Introduction
• Tone Configuration Tasks
• Example
27.1 Introduction
In-band tones keep the user informed about the state of his call or additional services such as call-
waiting, hold etc. Other tones can be related to any “event” that can occur during a call, for example
a call waiting indication etc. The In-band tones are referred to as “call-progress-tones”. Call-progress-
tones could be defined for different use, for tone-set profiles and for MGCP events.
27.1.1 Tone-set profiles
In traditional PSTN networks the in-band tones (dial tone, alerting tone, busy tone) are generated by
the network, i.e. the Central Office switch or a similar device, and are relayed transparently by the
SmartNode. In voice over IP networks however this model of a network side providing services
including in-band tones is not given in all situations. For example two SmartNodes may be
connected directly to each other over the access network without the intervention of a traditional
Central Office switch. This imposes the need to generate the local in-band tones directly on the
gateways (SmartNodes) since none of the attached ISDN devices (PBXs, phones) will do so itself
(ISDN USR side). The in-band tones that can be generated by the SmartNode are the following:
Dial tone:
Tone you hear when you lift the handset and the network is ready to accept the
dialed digits of the called party number.
Alerting tone: Tone you hear when the called party number is complete and the remote extension
is ringing.
Busy tone Tone you hear when the remote extension is busy.
The three call-progress-tones are collected in a tone-set profile. A tone-set profile collects typically all
the required tones for one country. The tone-set profile is assigned to a CS context and applies to all
PSTN interfaces on the CS context. If it is required to have different tones for individual PSTN
interfaces, the tone-set profile could be assigned directly to a PSTN interface. Doing so will override
the configuration in the CS context.
Figure 27-1 illustrates the relation ship between call-progress-tone profiles, tone-set profiles, CS
context and CS interfaces.
