Description: 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.
