ScoopTeam - User manual - Draft 0002
2.3.4. Wi-Fi interface (
NYA
)
A specific USB device (reference TBD) can be used to provide access to a Wi-Fi network.
It is possible to connect to an access point by entering the SSID and password for the network.
Access
control requiring a certificate and/or a login via a web browser is not supported.
The Wi-Fi connection can be used for remote control links and/or for AoIP connections.
2.3.5. Managing audio links
The audio transmission implies a link/session setup phase.
One of the transmission interfaces is selected as the
default interface
on the ScoopTeam. A call towards
a remote unit, initiated by the user of the ScoopTeam, is implicitly sent through this default interface.
The default interface can also receive and accept incoming calls from a remote device. The ScoopTeam
automatically picks up such calls.
On the other hand, an incoming call on an interface other than the default interface may be accepted
under certain conditions. These are described more precisely in 4.4.5, “Receiving calls”. In such case, the
ScoopTeam first switches to the suitable interface, and then processes the incoming call. When the link
is released, it will come back to its previous state (and default interface).
Note: If the unit is in double
codec mode and one codec is busy, the other codec is not available for calls on the other network
interface (e.g. IP link active, no ISDN call is acceptable)
.
2.4. Auxiliary transmission:
“relays” (
NYA
)
In addition to the main function of the ScoopTeam, which is the transmission of one or two main audio
programmes, auxiliary functions are available.
During an audio connection, two binary states can be transmitted end-to-end along with the audio
stream.
The transmitted data (also called “Contacts”) can be set via the user interface, using keys or a menu, or
set by input GPIs (see further in 2.5.5, GPIO).
The received states (also called “Info”) can be displayed on the screen and/or can activate relays/GPO
(see further in 2.5.5, GPIO).
This feature is only compatible with AETA products, because it is not covered by independent standards.
It is available depending on the transmission context, as follows:
For IP transmission and the SIP protocol, the feature is always available whatever the coding
algorithm (except L16/L20/L24).
For ISDN transmission, the feature is available only for G722-H242 or MPEG Layer II with J52.
The feature is not available in other configurations, including mobile voice transmission.
In double codec mode, this feature is only available for Codec 1.
