TC4411 CPU3 for TCIV Plus
Example: The
following initializing tones would set up
a laser player for a caller by setting the keypad to the
function mode and showing a frame and its numbering
on the screen: “O-*” (this combination assures that the
keypad will be in the function mode) and “9” (“Show
Frame and Chapter Numbers on the Screen”). To estab-
lish these as initializing tones at Location Code 64274,
64298, or 64302, enter “2490”:
10 [0] + (16 x 11) [*] + (256 x 9) [9] =
10 + 176 + 2304 = 2490
Media-Center Phone
Any Administrative display phone can be used to super-
vise Media-Retrieval operations. This includes program-
ming the system, reviewing the current users, and
assigning or canceling the use of individual media lines.
Standard Arrangement:
Ordinarily, an Administrative
display phone in the Media Center will handle these
functions. In this way, the person receiving media calls
can respond to calls
by
attending to the video players (e.g.,
loading the desired program and checking on problems).
The Media-Center line must be a standard Administrative
line (A: 1) but requires no special attributes.
Optional Programming:
It
may prove helpful to pro-
gram a Media-Center phone to receive calls from Display
Driver 2, and use Display Driver 1 for the Administrative
phones receiving non-media call-ins. Adding the A:7 Attri-
bute would immediately connect someone calling the
Media Center to an associated speaker.
Note:
A TC4400 Call-Control Console is designed pri-
marily for interconnect functions; it is not recommended
for Media-Retrieval functions.
Location Code 65388: Entering the Physical Number
of the Media Center’s phone here enables anyone com-
municating with an MRlOO to call the Media Center im-
mediately by flashing the hook switch, and to return
directly to the MRlOO by hook-flashing again. This quick-
transfer method can prove helpful when a user encoun-
ters difficulties, such as finding that the wrong tape or disk
has been loaded. To disable this function, store a zero at
this Location.
Caller ID: Starting with Version 204 system software,
any display phone will show the number of another
Telecenter phone that dialed it. The caller’s number will
appear on the right end of the display, in the “last-num-
berdialed” field. To indicate which number it is display-
ing, the system will put a colon (:) before the last number
dialed (as usual) and a “greater-than” (>) sign before a
caller’s number.
Media-Related Operation
Most of
the functions described here pertain to the user
who “calls” an MRlOO and uses the telephone keypad to
control the video player. The #24 supervisory function,
for reviewing and changing users’ connections to MRlOO
lines, can only be used by Administrative display phones,
and is especially intended for a Media-Center phone.
Controlling
a
Player
This section gives detailed instructions on controlling
a video player from a telephone. IL0344, at the back of
this manual, is an illustrated summary of these functions.
Establishing and Relinquishing Control
Note:
If your DSP phone is not programmed to access
a media line directly, call the Media Center to have the
desired line assigned to your phone.
Optional Single-Digit Dialing:
Telecenter
systems
with Version 204 or later software can provide singledigit
access to a media line
already
assigned
to your phone. You
would originally gain control of a media line through
dialing its full number or by having the Media Center
assign it to your phone. Thereafter, until you released the
media line, you could simply dial a single digit (e.g., “7”).
and the system would look to see which media line is
assigned to your phone and connect you to it.
Step 1.
Tune the television monitor to the channel
assigned to the desired video player.
Step 2.
Use the room phone to dial the number of the
desired player.
» The system will send a short beep when it has given
you control of the player, and will continue to beep
at one-second intervals.
(If someone else already has control, the system
will send you a busy signal. If your phone is not
authorized to call an MRlOO line, the system will
send
you
a single, long “disallow” beep; in this case,
call the Media Center to have the line assigned to
your phone, then repeat Step 2.)
Step 3.
After gaining control, use your telephone’s
keypad to operate the player (see the next subsection).
Step 4.
To operate the keypad, keep the receiver off-
hook. Once the player is running the program and you do
not need to send any more control signals for a while, you
can hang up.
» The player will continue running, and its media line
will remain assigned to you, which means no one
else can access it (unless the Media Center inter-
venes with the #24 function or an Administrative
phone with a call-in attribute, B:7 or B:8, dials the
line). Hanging up frees a Telecenter link for other
functions and lets you receive or make other calls.
Step 5.
To resume sending control signals, call that
media line back from the same phone, as in Step 2. (In a
system with version 204 or later software, you maybe able
to dial a single digit, like “7,” to reconnect with whichever
media line you still control.)
Step
6. If you need to contact the Media Center while
you are
connected to
the media line (e.g., because you
need a different program or there is a malfunction), simply
flash the
hook
switch (quickly press and release it).
You will be temporarily disconnected from the
media line and will ring the Media Center line (or
be connected to its associated speaker).
Note:
If your system does not use this function,
hang
up as in Step 4, then call the Media Center; you will retain
control of the player and be able to dial it back.
