■Facility and Non-Facility Associated Signaling
FAS and NFAS with or without D-Channel Backup requires admi nistration
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 c all
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 and Generation
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 sen d digit s on tr unk
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 param eters.
