Mapping MVIP-90 Resources
Mapping MVIP-90 Resources
RDSP, Vantage VPS, and Vantage VRS boa rds each use a single
data stream in the MVIP bus to send and receive data. Within
that stream, the driver assigns VP and line resources on these
boards to use a specific timeslot.
RTNI and Vantage PCI boards use internal streams for their
internal line and VP resources. Resources are pre-configured to
specific timeslots on those streams.
Mapping RTNI Resources
Mapping RTNI Streams
The RTNI series boards map the data received or transmitted
on its lines to data streams called internal streams. In T1 and
E1 boards, Trunk 0 uses internal stream 16 to transmit and
receive and Trunk 1 uses internal stream 18 to transmit and
receive. RTNI-ATSI boards only use stream 16.
Timeslots on these internal streams can be connected to
timeslots on any stream in the MVIP bus. When you send a
command to an MVIP switch block, you specify a board handle.
The switch block then switches data from the internal streams
on the board referred to by the board handle to the MVIP bus.
