Abstract
A method for facilitating communication between parent telephones and child telephones in a cordless telephone system. The method includes steps of dividing a plurality of channels into groups and assigning each parent telephone to one of the groups. When a child telephone is registered with one of the parent telephones, the child telephone may scan only the channels in the group assigned to the parent telephone with which the child telephone is registered, rather than the entire plurality of channels in the cordless telephone system.
