Parameters
ptype
The type of management primitive taken from the following table:
Value Name Function
8 Query Initiate circuit group query
circuit_status
This is an array of 32 octets, each octet indicating the state of a circuit. The
first octet corresponds to the circuit represented by the least significant bit of
the cic_mask. The status for any circuit for which the bit in cic_mask is not
set will be set to zero. The circuit state is as encoded in the ISUP circuit state
indicator defined in Q.763.(ISUP Formats and Codes).
7.6 Local Overload Request
This message may be used by the application to set a local overload
condition. This condition will be signaled to the remote signaling point by
inserting an automatic congestion control level parameter in all release
messages issued to the network.
