Fair Share routing
You can set the Call Distrib Type parameter to Fair Share so that a call is routed to the
available port that has been idle the longest. This value distributes the calls among several
destinations. In addition to routing a call by Phone Number, Src Slot, Src Port, and Call Rte,
Fair Share further sorts the call by Dst Slot and Dst Port. The existing internal routing criteria
for sorting still apply. You can configure the most specific slot and port by setting values other
than zero. You can configure the least specific slot and port by setting zero values. Table 4-3
shows the full-group ordering from most specific to least specific.
As shown in Table 4-3, calls whose destination is a nonzero slot and a nonzero port are at the
top of the sort order, and calls to a zero slot and a zero port are at the bottom of the order. If a
match is within the same group, the MAX unit routes the call to the port that has been idle the
longest first, and the least idle port comes last.
For example, the sort order for the calls in Table 4-4 is from the top of the table to the bottom.
For example, both the second and third rows of Table 4-4 show nonzero slots and nonzero
ports (Slot 7, Port 1 for row two and Slot 8, Port 2 for row three). If the MAX finds the
slot/port combination (7/1 or 8/2) that has been idle the longest gets the call. If one
