This attribute controls the percentage of trunk bandwidth which
may be reserved by outgoing path oriented traffic on the trunk. The
sum of requiredBandwidth attributes for all paths on this trunk must
not exceed this attribute. Setting this attribute to zero (0) prevents
paths from being established on this trunk. The limit of reserved
bandwidth for incoming path oriented traffic is set using the same
attribute on the trunk component on the other end of the trunk.This
attribute may be changed without the trunk being restaged. If the
value is decreased, calls may be bumped as necessary to free up
bandwidth. Increasing the value has no impact on existing calls and
new calls are able to use the new bandwidth.
If this attribute is set to greater than 100%, connectionless traffic is
given a minimum of 1Kbit per second for administrative traffic. A
value greater than 100% overbooks the trunk bandwidth. By
overbooking bandwidth, more calls are able to be established using
the unused bandwidth reserved by idle PLCs.
