Defining Routing Rules
Routing User Guide
Rule Destinations
The first parameter in a routing rule contains either the
send
command or the
balance
command, and contains one or more destination names.
The
send
and
balance
commands are described in detail below. Destination names are
described on pages
and
The SEND Command
Typically, the
send
command is used to specify a single destination, as in the example
below:
send("KANSASCITY")
when MODALITY="CR"
NOW={MON 00:01AM to 11:59PM;
WED 00:01AM to 11:59PM;
FRI 00:01AM to 11:59PM}
To send similar exams to multiple destinations, multiple rules would be used, as shown
below:
send("KANSASCITY")
when MODALITY="CR"
send("BACKUP")
when MODALITY="CR"
The BALANCE Command
Use the
balance
command when you want to divide a pool of exams between multiple
destinations. When using the
balance
command, you must specify what percentage of
exams should be sent to each destination.
In the sample rule below, 25% of the exams are sent to
KANSASCITY
, and 35% of the
exams are sent to
KANSASCITY2
. The remaining exams are not routed at all (as indicated
by the
<local>=40%
portion of the command).
balance("KANSASCITY"=25%,"KANSASCITY2"=35%,<local>=40%)
when MODALITY="CR"
 The total value of the percentages specified in the command must equal 100%.
