Class of restriction
For Communication Manager, MultiVantage™ Software, DEFINITY ECS, 
DEFINITY G1, G3, and System 75, the class of restriction (COR) places calling 
permissions and restrictions on both the calling party and the called extension. Up 
to 64 CORs can be defined in the system. 
For Communication Manager, MultiVantage™ Software, DEFINITY ECS, 
DEFINITY G3rV1, G3i-Global, and G3V2, the number of CORs has been 
increased to 96. For Communication Manager, MultiVantage™ Software, 
DEFINITY ECS and DEFINITY G3V3, each COR may be assigned a unique 
name via the Class of Restriction screen. CORs are assigned to trunks, stations, 
authorization codes, attendant consoles (as a group), remote access barrier 
codes, and loudspeaker paging access zones. CORs provide or prevent the 
ability to make specific types of calls or calls to trunks and stations with other 
specified CORs.
