Mailbox owners cannot send and receive any messages unless the configuration of every 
mailbox includes a Group Class of Service (GCOS).  The GCOS, which is essential to the 
operation of the system, manages communication among mailboxes for a particular set of users. 
The GCOS allows for the following:  

• 

It gives a system administrator the means to manage a large system with many mailbox 
owners, a useful option when some users need to exchange messages with each other but 
not with the majority of other mailbox owners. 

• 

It is useful at sites where some employees do classified work that should not be discussed 
with other employees. 

You can assign up to 32,000 GCOSs. 

You can perform the following procedures with GCOS.  These procedures are located in Volume 
2 of this manual.

There are two types of GCOSs, bitmapped and affinity group.  Bitmapped GCOSs are GCOSs 1 
through 64.  Affinity group GCOSs are GCOSs 65 through 32,000.  The two types work very 
differently, though you can mix both types in one system.   

Bitmapped GCOSs 

A bitmapped GCOS is a collection of groups.  A group is nothing more than a number from 1 
through 128.  Two users can exchange messages if their bitmapped GCOSs have any of the 
same groups.  To allow all users to communicate with each other, use the default GCOS 1.  It 
contains all 128 groups. 

Figure 8-2 shows three possible ways to set up the same bitmapped GCOS.  As the illustration 
shows, a bitmapped GCOS can have many, a few, or no groups defined.
