FROM

TOP
(Default) Selects the first idle circuit in decreasing CCI order. This strategy always
selects the highest available circuit.
With this circuit selection strategy, a series of calls might be placed as follows:
1.
A first call is placed on the last circuit, CCI max.
2.
A second call is placed on circuit (CCI max – 1), because CCI max is busy
processing the first call.
3.
The first call terminates, so CCI max becomes idle.
4.
A third call is placed on CCI max, because CCI max is now available.
5.
A fourth call is placed on (CCI max - 2), because both CCI max and (CCI max -
1) are busy processing calls 3 and 2, respectively.

BOTTOM
Selects the first idle circuit in increasing CCI order. This strategy always selects the
lowest available circuit.
With this circuit selection strategy, a series of calls might be placed as follows:
1.
A first call is placed on the first circuit, CCI 1.
2.
A second call is placed on the second circuit, CCI 2, because the first circuit is
busy processing the first call.
3.
The first call terminates, so the first circuit becomes idle.
4.
A third call is placed on CCI 1, because CCI 1 is now available.
5.
A fourth call is placed on CCI 3, because CCI 1 and CCI 2 are busy processing
calls 3 and 2, respectively.
DESCENDING
Selects a circuit by rotating circuits in decreasing CCI order, from the highest circuit
(CCI max) down to the middle of the route ((CCI max / 2) + 1). If no circuit is idle
on the second half of the route, a circuit on the first half of the route is selected.
With this circuit selection strategy, a series of calls might be placed as follows:
1.
A first call is placed on the last circuit, CCI max.
2.
A second call is placed on (CCI max – 1).
3.
The first call terminates, so CCI max becomes idle.
4.
A third call is placed on (CCI max – 2).
5.
For each subsequent call, the next lower circuit is selected up to the middle of
the route. When the last circuit in the half route is reached ((CCI max / 2) +
1), the selection strategy rotates back to the last circuit CCI max, because that
is the first available circuit in decreasing order of CCI.
ASCENDING
Selects a circuit by rotating circuits in increasing CCI order, from the first circuit (CCI
1) up to the middle of the route (CCI max / 2). If no circuit is idle on the first half of
the route, a circuit on the second half is selected.
With this circuit selection strategy, a series of calls might be placed as follows:
1.
A first call is placed on the first circuit, CCI 1.
2.
A second call is placed on the second circuit, CCI 2.
3.
The first call terminates, so the first circuit becomes idle.
4.
A third call is placed on CCI 3.
5.
For each subsequent call, the next higher circuit is selected, up to the middle of
the route. When the last circuit in the half route is reached (CCI max / 2), the
selection strategy rotates back to CCI 1, because that is the first available
circuit in increasing order of CCI.
