12.1.2.2. User Interface 
A phantom line can log on as an ACD Agent only if it is classmarked
as an Agent (AGENT) and it is restricted from both signing on and signing
off (NORELOC).
CHANGE-SDAT:STNO=2222,TYPE=ATTRIBUT,AATTR=NORELOC;
IMPORTANT:
The NORELOC attribute blocks the line
it is assigned to from performing autoset relocation (sign-on/sign-off).
A phantom Agent must be logged off from the line appearance where the
phantom was initially logged on.
Operation of the phantom Agent line is the same as for other keyset
lines which are Agents. The phantom line must be selected either manually
or via the keyset's originating line preference setting for the
phantom Agent line to be in use.
Some ACD features only operate on ACD keysets -- keysets whose prime
line is an Agent. Also note that the ACD LEDs that indicate Agent modes
and call queue status only apply to the device's prime line and
not any secondary or phantom line appearance.
Phantom lines can be classmarked as ACD Supervisors (SUPER) and as
autologon extensions (AUTOLOG). However, phantom lines are blocked from
acting as ACD group Supervisors and from being automatically logged on.
