7.22.  The Tandem configuration  
 This configuration lets you group two sets under a single call number. Your set is then the main set 
and the second set, usually a DECT set, is the secondary set. Each set has its own directory number, 
but the tandem number is that of the main set. When you receive a call, the two sets ring 
simultaneously. When one of the sets answers, the other set stops ringing. When all the lines of the 
main set are busy, the secondary (DECT) set does not ring. The secondary set can still be called by its 
own number, but in this case, the tandem function will no longer be taken into account. Most of the 
functions are common to the two sets, for example: forwarding, meet-me reminder, the various 
messages, etc., while others are specific to each set, for example: individual directory, last number 
redial, out of service, set padlock, etc. 
 For more information regarding this configuration, contact the person in charge of your installation.
