Cobalt Digital COMPASS 9220 Bidirectional ASI_MPTS Gateway - Manual (Page 8)

8 9220-UM V1.1
If you are making one-to-many connections, step 1 is performed once, and step 2 is performed
multiple times. It is also possible to configure the output first (without making the connection to
an input), configure the input next, and finally make the connection between the input and the
output.
Note that while it is possible to connect one given input to multiple outputs, only one connection
is allowed for a given output.
The overall architecture is depicted below.

Inputs Outputs
For the remainder of this manual, we will use the term port for a physical input/output port (such
as ASI or Ethernet), and stream for a transport stream present in the port. ASI ports support only
one stream, while Ethernet ports support multiple streams.
Redundancy Options
The 9220 can be configured to support transport stream redundancy. This means that the unit
can be configured with a “primary transport” and a “backup transport”. If the primary transport
disappears, the unit may be set to automatically switch to the backup transport, after a
configurable timeout. The following features are common to all redundancy modes:
