BRI Protocol
Select between the following BRI protocols:
 ETSI (Euro ISDN)

Bearer capabilities
Within ISDN different bearer capabilities are used to signal the type of date (Voice, Data, H320,
H324M), which is used by switches and other equipment to determine what to do with the data or
the call (compressing voice data, neglect etc).
 Incoming: sets the ISDN bearer capability of the incoming 3G calls.
o UDI: In some situations the non correct UDI (Unrestricted Digital Information )
bearer is used in stead of the right H324M capability. This setting makes it
possible to accept incoming 3G calls with UDI bearer signalling.
o ALL: Means that calls no matter which bearer are accepted. This makes it
possible to even accept audio calls.
 Outgoing: sets the ISDN bearer capability for the outgoing 3G calls.
o H324M: This ITU standardized capability is selected for outgoing calls by default.
