Australia Malicious Call Trace
Avaya Communication Manager with a BRI connection to the Australian public network is able to
notify the network if a user in a private network invokes the Malicious Call Trace feature. This
works on Australian national connections.
•
Direct Inward Dialing
Some public network operators may not offer full DID service on BRI trunks, but instead may
offer the BRI equivalent, which typically is called MSN. This is the case if the public network
treats the BRI as an endpoint interface rather than a trunk group interface.
In such a case, the network only routes up to 10 public numbers to a particular pair of BRI trunks.
Furthermore, the network may not let calls overflow from one BRI trunk to another.
•
D-Channel Backup
D-Channel Backup is not supported on BRI connections.
•
Distributed Communications System
If both DCS and ISDN features are provided over the same facility with a DEFINITY server,
DCS displays generally override ISDN displays. However, with Avaya Communication Manager,
the ISDN connected name and number can override the DCS called name and number if the
Display Connected Name/Number for ISDN DCS Calls
field is y on the Feature-Related
System Parameters screen.
BRI trunks support DCS if using a BX.25 link to transport the DCS messages. DCS+, also known
as DCS Over ISDN D-Channel, according to the AT&T protocol, is not supported on BRI trunks.
•
Facility Test Calls
Neither BRI or PRI trunks support Facility Test Calls.
•
France VN4 Protocol
The France national VN4 protocol is supported on BRI trunks as ETSI.
•
Generalized Route Selection
BRI trunks are capable of carrying 56Kbps or 64Kbps data calls. The link coding that restricts
certain PRI trunks to 56Kbps only does not apply to BRI trunks.
•
German 1TR6 Protocol
The German national 1TR6 protocol is not supported over BRI trunks.
•
Message Sequence Tracer
ISDN-BRI trunks support Message Sequence Tracer. However, certain filtering capabilities
available for PRI trunks are not available. Specifically, it is not possible to filter BRI trunk
messages based on incoming/outgoing calling/called number.
•
Network Access - Public (LEC/AT&T/Other Carriers)
Public-network access using BRI trunks is available but only in those countries that support
point-to-point BRI connections. In the U.S., BRI access is offered only by the Local Exchange
Carriers and not by Interexchange Carriers such as AT&T.
•
Network Access - Private Premises Based
Full support for private-network connections using BRI trunks is available.
•
Non-Facility Associated Signaling
Non-Facility Associated Signaling is not supported on BRI connections.
