4.4 Using Line Groups

Some systems have telephone lines arranged into line groups that are made available at the telephone instead of individual lines. Your system administrator can tell you how your system is arranged. When line groups are available, you may access them for outside calling instead of pressing a line button to select a line for use.

∙To access a system line group,

1.Press INTERCOM.

2.Dial desired line group access code:

9 = line group 1

81 = line group 2

82 = line group 3

83 = line group 4

3.Listen for outside dial tone.

4.Dial desired number.
