Switching Calls through the MVIP-90 Bus
Connecting Local Resources
An RTNI board can connect a line to a remote resource through
the MVIP bus, or connect two lines on the same board. For
example, the T1 board in Figure 30 is connecting an incoming
call from its second line (16, 1) with its fourth line (16, 3). In this
example, the T1 board’s switch block does not contact the MVIP
bus. When you call SET_OUTPUT to make this connection, you
would specify the board handle of the T1 board you want to use.
