Internal Touch Tone Option (ITTO)

For Touch-Tone Power Control
Use with  ARR, ARR+, CPS, U-X3, U-X1

This controller allows you to directly control one or more power control devices remotely over a standard analog POTS telephone line or the analog frequency on a DSL line (filter required) using Touch-tones. Additionally, the phone line can be shared with an answering machine (TAD) or a standard analog telephone and most fax machines.
Do not use on digital PBX or ISDN lines.

Look for the label just above the RJ-connectors on the power strips or the front panel of the U-Xx devices to determine if this option is included. If it is, simply connect the phone cable from the wall directly to the RJ-11 “Phone or Telco Connector” and you are ready to go. You might first connect the line to a standard telephone to check for a dial tone.
 
Now you can call that number and RESET the AC Jacks or turn them ON or OFF. You can also make Status inquiries relating to the power state and setup. Additionally, ITTO provides a powerful bi-level Password (PW) feature that can also be changed remotely.

Using the Touch tones to change the PW is handy if you have a number of units at different locations or have them dropped shipped. You could even have a different PW for each location or change them after every power command (one time PW) for highly secure applications.

The PW feature also allows you to connect multiple PCDs, with different PWs to the same line at the same location. They can be “daisy chained” to each other using the RJ-11 connectors or dropped off of the same line in a traditional telephone loop wiring topology (also see “Connecting a FAX”). When accessing them, they will all answer, but only the one with the proper PW will remain off hook to interact with the caller. You can also program different groups with the same PW (maximum 4) although the responding “beeps” from several PCDs may get a little confusing. Normally the initial PW change is made on each PCD individually. Otherwise all would respond to the 1-2-3-4-5-6# default PW. Use the Touch-tones or the serial port if available to change them.
Note: Do not confuse this with the addressable daisy chain features of some of the PCDs. This uses the ITTO PW method to select the device to achieve a similar result. DO NOT try to mix the two methods. 

To accomplish any of these options, you need a telephone (land or cell) that can generate Touch-tones. A modem may also be used for a more automated procedure. A series of ‘beeps’ maintains communication with the caller. Normally two short “beeps” is the acceptance of a command and a single long “beep is a rejection. The “beeps” are also used as responses to Inquiry Commands.

AC Power Commands (#0x)

To control the PCD with touch-tones be sure that the phone line is connected to the “Phone or Telco Port” on the PCD. Then dial the phone number where it is connected.

1. When you hear the “beep beep”, enter the Password if used. You will get another pair of “beeps” if it is accepted. Otherwise the call will be disconnected (bad call).
2. Enter #0x (x= the number of the AC Jack that you wish to control, 1-2-3).

For the ARR, ARR+ and U-X1 the x must = 1. The Controlled Power Strip CPS and U-X3 on the other hand allows you to select specific AC outlets 1-2-3. You can also use a wild card (#) and they will all execute the command. Check the label under the Surge Protection LED on the power strip for the model that you have.
4.    Enter the ON/OFF or RESET Command (1=ON, 2=OFF, 3=RESET)

Example 1
1-770-945-0643 “bb” #123456# “bb” #0  2       1“bb”                          #90  “bb”
  Phone  Number                      PW                    Jack   Command (ON)      Exit
       Do not enter the spaces. They are there for clarification only.
This command string would turn ON the power on AC Jack pair #2 on a Controlled Power Strip (CPS) or U-X3.

The command can also be entered with a modem call, even though there is no modem at the receiving end where the power strip is located.
Simply add it to the AT dial string. This may be a handy way to help automate your control procedures.
                                  Example 2
ATDT 17709450643@ #123456#, #021, #90
The @ sign represents a 4 second delay to give  ITTO  a chance to answer. The commas represent a 2 second delay to accommodate the “beep beep” responses.

You can send more than one command while connected to the same device if you do not send the #90 exit command. No need to enter the PW again. Just start with the #02 in the example or any of the following #xx commands. ITTO will accept commands as long as you are connected. If no commands are entered in 11 seconds or the caller hangs up, the call will be disconnected.

Inquires Commands (#6x)

You can inquire the status of the AC power in much the same manner. In the example enter #60 instead of the #0x.

You will hear a beep responses. Two beeps response is ON and a single long beep is OFF. When inquiring the Controlled Power strip (CPS) or U-X3, each of the three pairs will respond in sequence with a short pause between them, i.e “beep beep” pause “beep beep” pause “beeeep”. This indicates that AC outlets 1 and 2 are ON and 3 is OFF.

You can also make other inquires using the #6x command.
#60 inquiries the status of the AC jack pairs.
        Double beep = ON,           Single long beep = OFF
#62 inquires the PW  (Admin PW required)
#67 inquires the Ring count
#65 inquires Reset OFF time

Developing your Bi-Level Password (Default PW is #123456#)

The Password (PW) is fixed at six numeric characters. However, you can divide the six characters into a User PW and an Administrative PW. In other words you can use three or four characters for the User PW that you can give to the users and use the other two or three characters as your secret Admin PW. Use the second # sign to separate the six digits.

The User PW can only be used to turn the Power ON/OFF or RESET and make power status and Ring count trigger status inquiries. Whereas, the complete 6 character Admin PW can also be used to change the PW or make other remote programming changes.

Changing the PW (#2xxxxxx#)
To change the password using Touch-tones:

1. Enter the current Admin PW after ITTO answers (all six characters are required) and wait for the “beeps”
2. Enter #2 followed by the new User PW.
3. Enter # for the Admin PW separator and the remaining digits to equal six. 

                         Example 3
     Current Admin PW “bb” #2 123#456  “bb”     
        This would result in a User PW = 123 and an Admin PW = 123456
In Example 1, user access PW would now be 1-770-945-0643 bb #123# bb etc……
If you enter all six digits with the # at the end, the resulting PW would have both User and Admin privileges. If the # were entered at the beginning there would be no User PW. The User would simply enter ## to begin a command after ITTO answers. The Admin PW would still be composed of all six digits.

 ** Do not Hang Up before confirming the new PW with the #62 command **

You will hear a series of beeps for each of the six characters so get your pencil ready. A long beep will separate the User PW part from the Admin PW part if any. Two quick beeps are used for a zero. If the # is at the end, you would get the long separator “beeeep”.

Remember, if you hang up or enter the #90 Exit command or wait more than 11 seconds without being sure of the new password or you may not be able to get back in. Keep making inquires/changes until you are sure.

If you find yourself in a “lock out” predicament, you can only enter a new PW through the serial port, if available.

PW Inquiry  (#62) (Admin PW required)

1. Call the Power Strip and enter the Admin PW.

Wait for the two acceptance beeps.

1. Enter #62 to inquire the password.

Have your pencil ready. See previous “beep” explanation.

Using the Serial Port
To change the PW Use:          *PW        123456#  (Default)
Check it with a                        *?PW     (Listen for the “beeps”)
   See the SerialPort instructions for the PCD that you are using.

Caution: Be sure that the first two characters in your PW is NOT the same as the first two characters that might be used to remotely control an answering machine (toll saver) or other analog device connected to the same phone line.

Programming the ring count #7x
The x represents the number of rings to answer (1-9). The default is 3. The ring count selection depends on how you intend to use ITTO.

If ITTO is the only thing on the line you might want it to answer on the first ring. However, if using a phone on the same line, you might extend the number of rings to give the phone call a chance to be answered before ITTO grabs the line. If using an answering machine, program the number of ITTO rings to answer after the answering machine. ITTO will keep listening for its Touch-tone PW and commands even though something else has answered the line. If it doesn’t see a valid Touch-tone, it gives up after six seconds and the call continues with the phone or answering machine. Do not use with voice mail service from your phone company.

If the Ring Reboot feature had been enabled through the serial port, this would be used as the Ring Count RESET trigger. Normally the Ring count RESET feature is not used with ITTIO.

Note 1) A ring count of zero is illegal. Otherwise there would be no way to get back in. This can also be programmed through the serial port if available.
2) If multiple ITTOs are on the same line don’t use the same ring count in more than four units unless something else answers the line.

Programming the RESET OFF time #5x
The x represent the Power OFF time when a RESET command is issued.
0-9 is valid. The entry is multiplied by 10 seconds. The default is 5 seconds. Check it with the #65 Inquiry Command.

This completes a dial in session. The confirmation beeps will be heard before the line is disconnected. Hanging up the call or waiting 11 seconds will also disconnect the line (no beeps).

ITTO Express (4-1-08)
Express Power Commands
Now that you have mastered the ITTO command structure, note that there is also an express method of entering the Power Commands. It may save a few touch tone entries and “bb” wait times. Note that the Express only works for the AC power commands. It is intended to quickly control the ON/OFF or RESET function for one or more (same PW) Power Control Devices connected to the same phone line or in a daisy chain.

To enter an Express power command you would precede the user PW with a * instead of the #.  
                                              Example 4
           770-945-0647 “bb” *PW3 “bb”    (disconnect)
This would RESET the AC power on all of the Controlled AC Jacks on PCD and then disconnect.

A *PW1 “bb” would turn the power ON and a *PW2 “bb” would turn the power OFF on all of the Controlled AC Jacks. If no PW were used, a *3 “bb” would execute the RESET command in example 4. It is up to you to develop a user PW commensurate with the level of security versus  convenience that you are trying to achieve. See “Developing Your Password” above.

Notes:

1. Be sure that you hear the confirmation “bb” at the end otherwise the command was not executed.
2. The line is disconnected after a good or a bad call (invalid PW).
3. No additional commands can be executed on the same call.
4. If the RESET or ON command is executed, be sure to give your equipment a chance to boot up before placing another “power control” call.
5. Do not use the Express method to specify separate Jacks on the 

         Controlled Power Strip. You would have to used the #xx commands.

Connecting a Fax
You can connect a fax to the same line, providing the fax is the type that can answer the line and act as a controller to determine if the call is a fax call or not (most are). Normally this type of fax will have an “in” and an “out” RJ-11 connector. They may have various labels. Normally ITTO and a TAD would be connected to the “out” or downstream connection of the fax machine.

Some fax machines will re-ring the line on the “out port” if it is not a fax call however most will simply let the rings through and rely on something else to answer the line. They then listen for the fax tone (CNG). If it is a fax call, it will disconnect the “out port” and process the call.

Do not configure the fax for Auto answer as you would for a dedicated fax line. The resulting CNG tone or constant carrier signal will conflict with the ITTO PW tones. Call the fax with an ordinary phone to be sure the line is quite (no tones) when answered. The voice announcement from the TAD or “hello” from a phone is ok. Consult your fax manual or fax vendor for further information, not your ITTO vendor, please. Just can’t keep up with all of them.
