Line groups
The numbers 9, 8, and 71–76 are designated as line groups. A line group is, as the name implies, a specific
group of lines in a key system that are used for making outgoing calls. In an ESI Communications Server, line
groups give phones access to outside lines without taking up any programmable keys on each phone.
Note: Line groups 71–76 may conflict with Esi-Link locations 710–769 (if they're needed); refer to Function 164
(see page E.6).
