This section applies to E1, T1 and ISDN technologies only. 

The Global Call RTCM feature allows the customer application to retrieve or change the default 
configuration of a GCLib even before any line device is opened. Figure 27 shows the procedure for 
synchronous mode. 

The following describes the procedure for getting or setting the configuration of the GCLib in 
synchronous mode: 

1. Load the GCLib (after the gc_Start( ) function is called). 

2. Create the target object data (a GC_PARM_BLK data structure) with the appropriate set ID, 

parm ID, value size, and value, if applicable, by calling the Global Call utility functions 
gc_util_insert_parm_ref( ) or gc_util_insert_parm_val( ). See the Global Call API Library 
Reference for more information. 

3. Call the gc_GetConfigData( ) or gc_SetConfigData( ) function with: target_type = 

GCTGT_GCLIB_SYSTEM
target_id = 0
time_out = 0
mode = EV_SYNC
