World-Class Tone Detection and Generation 

■

Facility and Non-Facility Associated Signaling

FAS and NFAS with or without D-Channel Backup requires administration 
via signaling groups for trunk-side wideband interfaces.

■

Facility Busy Indication

You can administer a busy-indicator button for a wideband-endpoint 
extension, but the button does not accurately track endpoint status.

■

Facility Test Calls

Use Facility Test Calls to perform loop-back testing of the wideband call 
facility.

■

Generalized Route Selection

GRS supports wideband BCC to identify wideband calls. GRS searches a 
route pattern for a preference that has wideband BCC. Route preferences 
that support wideband BCC also support other BCCs to allow different call 
types to share the same trunk group.

■

CO Trunk (TTC - Japan) Circuit Pack

The CO Trunk (TTC - Japan) circuit pack cannot perform wideband 
switching. No member of the circuit pack should be a member of a 
wideband group.

World-Class Tone Detection allows DEFINITY ECS to identify and handle 
different types of call-progress tones. The tone detector and identification is used 
to display on Data Terminal Dialing and for deciding when to send digits on trunk 
calls through Abbreviated Dialing, ARS, AAR, and Data Terminal Dialing.

World-Class Tone Generation allows you to define call-progress tones. You can 
select values for frequency and cadence. If you do not define a call-progress tone, 
DEFINITY ECS sends silence. Brief call-waiting tones are optimal because, 
while a tone is sounding, speech cannot be heard.

A Lucent representative must administer tone detection and tone generation when 
establishing country-specific system parameters.
