■ Class of Service (COS)
COS determines the class of features that a wideband endpoint can
activate.
■ Facility Associated Signaling (FAS) and Non-Facility Associated
Signaling (NFAS)
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)
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 and
Generation
World-Class Tone Detection allows Avaya MultiVantage 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,
Avaya MultiVantage sends silence. Brief call-waiting tones are optimal because,
while a tone is sounding, speech cannot be heard.
An Avaya representative must administer tone detection and tone generation when
establishing country-specific system parameters.
