■ 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.
■ Temporary Signaling Connections
Avaya MultiVantage does not support Temporary Signaling Connections
according to the AT&T protocol on BRI trunk interfaces. Only the QSIG
NCA TSC protocol is supported on these interfaces
■ Wideband Switching (NxDS0)
Avaya MultiVantage does not support wideband switching on BRI
connections.
