DTMF (DIGIT) DECODERS

Touch-Tones are used in every aspect of business today!   It's time to have a DTMF Decoder!

If you can't test DTMF to see if it's being sent and received correctly, how can you efficiently troubleshoot your customer's equipment? This is an investment that will pay for itself by saving you just a few hours of chasing your tail!  Now you can "see" Touch Tones!

One great application is getting the Speed Dial #'s out before swapping out equipment. The customer usually doesn't have a list of all those Speed Dial numbers, so they're thrilled when you give it to them!

Don't guess!  Use our Decoders for diagnosing problems with:

  • Voice Mail
  • ANI
  • IVR
  • DTMF DID (The Dialer Buddy does both Rotary and Tone DID)
  • Speed Dial
  • Checking Dialers
  • Decoding ABCD digits (AUTOVON, PBX In-Band Signalling, and Alarm Systems)
  • Simple SMDR (on the Tone Master TM16 Plus model with serial port, and the Dialer Buddy)

You're wasting your time trying to fix this stuff without these inexpensive Digit Decoders...in many cases problems can't be fixed without one!

Cabullet.gif (978 bytes) CALLER ID LINK: Windows TSR Type Program for SCREEN POPS

Plug your Whozz Calling (Full Feature only, but not with Memory/Modem) into a serial port on your PC, and it will record all activity, including outgoing if you have a Full Feature unit, into a flat file on your hard disk. It starts automatically with windows. Everything is time and date stamped. For incoming calls, the program leaves the last Caller ID number received in a separate file for each line (like whooz01.dat, whooz02,dat, etc.).

If you want to bring Caller ID into a custom written program, you simply have the program open the small flat file for the appropriate line number, when you want to do a screen pop for that line.

It's usually easier to read and parse the information from a file, than to read the serial port (which is what Caller ID LINK does for you). You might even be able to read the flat file from a regular database program (like Access).

Since you never know which line you need to answer (Murphy's Law says that more than one line is going to ring at the same time), your program needs a way for you to tell it which line you're going to answer, so it will pop the correct information.

If you have 12 or fewer lines, the F Keys (above the numbers on a keyboard) are the easiest to use (if your program doesn't already use them). You may also be able to use a two key combination, like SHIFT and the F Key.

This works best on a Square Key System (where all of the lines are the same line number on every phone). That way, someone can hit the F Key even before they answer the line, to see who's calling. On a PBX, you could hit the F Key after the line is answered, if the line number is shown on the phone's display.

Requires Windows 95 and up, a PC with a minimum 486-66 with 32 meg of RAM, a serial port, hard drive with 10 meg free, and a Network Interface Card (NIC) so other computers on the network can access the Caller ID data. This PC becomes the Caller ID Server.

Caller ID Watch PLUS Inactivity Warning Screenshot

Requires Windows 98 or up, minimum Pentium 100 with 256meg of RAM, a real serial port (not a USB/serial converter), hard drive with 200 meg free, a Super VGA (800x600 minimum) Monitor, and a NIC (Network Interface Card) if you plan to use it over a network or over the Internet.

The voice features (spoken Caller ID) require a sound card and speakers.

Comes with a Dongle that connects to the serial port on the PC that's collecting the data from the Caller ID Box. No limit on the number of client PCs.

IMPORTANT NOTES:

1. If the information you need from Caller ID Watch Plus is important to you, you should probably run it on a dedicated PC. If other software on the PC crashes Windows, you'll lose the information until the computer is reset. Even old versions of Windows (like 95) do an incredibly good job if there is only one program running on the PC. Be sure to remove everything from the Startup Group, and stop the Virus Scanning software on that cheap dedicated PC.

2. Caller ID Watch Plus Network uses UDP Packets which are not absolutely guaranteed to get to the client PC. In reality, we haven't seen dropped packets on the network, but you shouldn't use the network for life safety applications. Even if a packet gets dropped over the network, the main PC collecting the Caller ID information will have all of the information in its log. To get the UDP packets outside of your network, you'll need to choose a port for them to be sent on, and that port will have to be opened in the firewalls.

3. If you plan to view Caller ID information over the Internet from a PC that has a dynamic IP address (that changes often like residential cable, DSL or a cellular phone data connection), you'll have to click on the Network Setup Wizard each time the IP address changes to send the new IP address to the main PC running Caller ID Watch Plus Network. That takes about 10 seconds.

Cabullet.gif (978 bytes) PULSE TO TONE CONVERTER

Pulse to Tone Converter
NEW VERSION!


Pulse to Tone Converter

Use legacy phone equipment with lines that only works with DTMF!

Lets you use a rotary phone on a PBX, Key System, VoIP Adapter, Cable TV Phone Adapter, or other type of line that doesn't accept pulse dialing. Lets you use antique phones on a modern PBX!

Line powered. This NEW VERSION will work on lines that accept Rotary Dialing as well as Touch Tone. You won't get double digits!

This NEW VERSION doesn't send the pulses from the rotary phone to the phone line, so it should work with most fake phone lines that don't accept rotary dialing. The old version would send the pulses through to the line, followed by the DTMF digit, sometimes creating double digits or other problems.

NOTE: We have a limited quantity of the old version available at a discounted price, which would still work for you if they worked for you in the past.

Cabullet.gif (978 bytes) DTMF RELAY

View DTMF Relay

This amazing device will give you a dry closure in response to a pre-programmed DTMF string. Program the closure for half a second, one second, turn it on or off with different codes, or toggle it on and off with the same code. It's always listening on the line.

It has two normally open relays that can be operated at the same time or independently. Useful for switching both the tip and ring to keep the line balanced.

Turn on lights, sirens or anything you can think of by dialing the pre-programmed code. Dial the code from a phone on either end of the call.

It does NOT answer the line. The line must be answered by voice mail, a person, or an answering machine (with or without a greeting) with CPC and/or silence detection (so it will hang up when you're done).

This is a very flexible device that is programmed from a Touch Tone phone. Because it's so flexible, programming can be rather daunting. There are a lot of options.

Easily installed on an analog CO line or station port using a modular jack. Screw terminals for the relay. Use a slave relay for high voltage devices. Password protected programming, remote or on-site, via a DTMF phone.

Requires 12VDC power supply. Draws 40ma.

DTMF FLASH GENERATOR

DTMF Flash GeneratorDTMF Flash Generator

This amazing line powered device will flash (or hang-up) the line for up to a second in response to a pre-programmed code. It's always listening on the line.

A great device for phones without a flash key or no buttons left to program as a flash key. Put it on an Automated Attendant and allow it to do a Centrex flash right on the CO line, to transfer calls off premise. Put it on a cordless phone with no flash key. It will always flash the line for the pre-programmed time when it hears the pre-programmed trigger code. No guessing about how long to hold down the hook-switch! Dial the code from a phone on either end of the call.

The DTMF Flash Generator works well in response to DTMF A, B, C and D tones (fourth column tones).

The line powered DTMF Flash Generator is easily installed in-series with an analog CO line or station port using a modular jack. Programming is password protected, for remote or on-site programming via a DTMF phone.

Using the DTMF Flash Generator to provide a CPC:

Many phone systems allow in-band signalling to indicate to the device connected to an analog station port that the trunk has received a CPC signal from the phone company, and the outside party has hung-up. In-band signalling can be a DTMF digit (including A, B, C and D fourth column tones), dial tone, busy signal or reorder tone. These tones are usually used to signal a voice mail system that the outside party has hung-up.

It's usually necessary to program the phone system's analog station port as a voice mail port in order to use in-band signalling (this is how integration was done in the past). If the system supports sending a DTMF digit when it receives a CPC signal on a trunk, this is the most dependable way of proving an open-loop disconnect to the device on the analog station port. Any other methods have to recognize a tone or silence, which can lead to cut-offs when you don't want them.

Keep in mind that even if the phone system does support in-band signalling when it receives a CPC on a trunk, it may not send the DTMF digit when on a station to station call. That means that a voicemail will hang-up on trunk calls, but not on messages left from a station

In any event, you'll have to do some programming and testing, listening to see if there's a DTMF digit as a CPC on both trunk-to-station and station-to-station calls.

Cabullet.gif (978 bytes) DTMF TONE GENERATOR

DTMF Tone GeneratorDTMF Tone Generator

This amazing line powered device will dial whatever DTMF digits you want, in response to a pre-programmed code. It's always listening on the line.

Most Popular Use? Northern Telecom Voice Mail systems can't send a # while sending a DTMF message notification to a pager (# tells the system to hang-up), which some pagers need as an 'Enter key" when done with a message. Simply program the DTMF Tone Generator to activate when it hears a **, and it will dial a # onto the phone line. Dial the code from a phone on either end of the call. Pretty slick!

It's easily installed in-series with an analog CO line or station port using a modular jack. Password protected remote or on-site programming via a DTMF phone.

Most people use this to dial a pocket pager or cell phone, to let them know that something is in an alarm condition.

Short the contracts, and it will dial the phone number you program into it, followed by another string of digits that you program into it. These digits may indicate the site location, the type of alarm, etc. There are two inputs for dry closures, so you can have two alarm conditions sent by DTMF string.

Easily installed on an analog CO line or station port using a modular jack. Easy clips for connecting the wires for the dry closure. Password protected programming, remote or on-site, via a DTMF phone.

Requires 9VDC power cube (Part number TOH90 at $8.95).

Part Number: CID9T   Price: $139.95
