For many UG members with cordless phones this can quicklylead to a DECT system overload, with the result that not all cordlessphones are called. Therefore use the cordless phones user groups 1 - 24 ifthere are many members (see "Cordless phones", page 149).5. 7. 3. 4 Application example for a user groupIn the call distribution pattern, general bell has been configured with a delay; alongwith the operator consoles. This means that if the operator consoles is overloadedthe general bell will also start to ring after the configured ringing time (e.g. 3 ring-ing cycles). The call can then be taken from any terminal.Other Subjects Related to the User Group:Call distribution, User configuration, Operator Consoles, General bell,Internal traffic, Incoming traffic, User group: logging in and out, Number-ing plan.Aastra Intelligent Net:In an AIN the user group works across networks, i.e. the elements of a usergroup and the members of a member group can be spread across differ-ent nodes.
