“VCR” indicates
the player’s line, which may be either
a video-tape or
a laser-disk player. The first display shows
that the player on
Media Line 7 17 is currently assigned to
phone line 105. The second display indicates that player
7 18 is currently available.
releasing a Media Line, any Administrative phone with a
call-in Attribute (B:7 or B:8) can gain control of that line
by calling it. However, only the #24 method allows you
to assign control to another user.
To pre-assign a player to a specific station:
Enter the
Architectural (dialing) Number of the station. The display
will then list the new station owner. Unless an Adminis-
trative phone intervenes, only that owner can call this
player, and the player will receive the initializing tones
when it is called.
Note: It is possible for an Administrative phone to use
the normal call-transfer function to”transfer” a Media Line
to another phone. However, this method is not recom-
mended because the original “caller” would retain control
of the media line. Thus, the user who received the transfer
could not call the media line back after hanging up.
To terminate a connection: Press the
asterisk ("*“)
key on your dial pad. The display will show that the line
is “Free.” Pressing the "*" key when the player is already
“Free” will send the ending tones to it (see “‘Automatic
Control Signals” under “Media-Related Programming,”
above).
Notes: This method works whether or not a user is
connected to a Media Line. If a user has hung up without

Button: This is meant to release a
player from a user who has finished with it but failed
to relinquish control before hanging up. Unlike the
#24 method, this method does not send ending tones
to the player.
“VCRxxx =
65535”: The #24 review function will
show this value instead of “Free” for a player that was
released without receiving the appropriate ending
tones (“0”
for a laser-disk player, “0” or “5” for a VCR).
To eliminate this setting, call the player, then release
it with the appropriate ending tones.

the next Player extension:
Press the “#" key.
When you have gone through the entire list of player lines,
the words
“END LIST”
will appear in the display, and the
system will ignore
any
subsequent key entries. To end the
review at any point, hang up.
Dialing Staff Phone (DSP) A:24
This line type is similar to an Administrative line but is
typically used in a room with a speaker (and sometimes a
call switch). DSPs receive dial tone and may dial calls
directly
just like an
Administrative
phone. The differences
are that a DSP cannot have a display, receive call-ins from
room stations, activate alarm tones, or do executive over-
ride. These restrictions free “B” Attributes 5, 6, 7, and 8,
which serve other purposes (see “DSP Attributes” im-
mediately below).
