The following are the relevant function parameters:

target_type 

GCTGT_CCLIB_NETIF 

target_id 

IPT board device

datap

pointer to GC_PARM_BLK with additional response information

Because some of the data may be protocol specific (in future releases), there is a facility to set the 
protocol type using the following IP parameter element in the GC_PARM_BLK, datap:

IPSET_PROTOCOL

IPPARM_PROTOCOL_BITMASK
and one of the following parameter data values: 

IP_PROTOCOL_H323 

IP_PROTOCOL_SIP 

IP_PROTOCOL_H323 | IP_PROTOCOL_SIP 

The default value for the protocol when not specified by the application is IP_PROTOCOL_H323.

The GCEV_SERVICEREQ event indicates that a service has been requested by an H.323 
gatekeeper or a SIP registrar. The event is received on an IPT board device handle. The event data 
includes a specification of the protocol used in the following parameter element:

IPSET_PROTOCOL

IPPARM_PROTOCOL_BITMASK
and one of the following parameter data values: 

IP_PROTOCOL_H323

IP_PROTOCOL_SIP

The gc_SetAlarmParm( ) function can be used to set QoS threshold values. The function 
parameter values in this context are: 

linedev 

The media device handle, retrieved using the gc_GetResourceH( ) function. See 

, on page 264 for more information.

aso_id 

The alarm source object ID. Set to ALARM_SOURCE_ID_NETWORK_ID. 

ParmSetID 

Must be set to ParmSetID_qosthreshold_alarm. 

alarm_parm_list 

A pointer to an ALARM_PARM_FIELD structure. The alarm_parm_number field is not used. 
The alarm_parm_data field is of type GC_PARM, which is a union. In this context, the type 
used is void *pstruct, and is cast as a pointer to an IPM_QOS_THRESHOLD_INFO structure, 
which includes an IPM_QOS_THRESHOLD_DATA structure that contains the parameters 
representing threshold values. See the IPM_QOS_THRESHOLD_INFO data structure pages
