Clear-Com HX System Frames - Manual (Page 154)

Ready—Signals that the system is ready for a selector code entry. It also indicates that it
has acknowledged the last selector code entered. The prompt consists of a single high-
pitched tone.
Error—Indicates that an invalid code has been entered. Error prompts result from:
1) Selecting a code that is less than 10 or greater than 59
2) Selecting a code without talk or listen labels assigned to it
3) Assigning a control code before a port has been activated.
Multiple codes
If the Multiple Codes is set to false only one selector code can be active at a time. Entering
a second selector code automatically deactivates any audio paths that were activated by
the previous selector code. If this field is set to true, any number of selector codes can be
active at the same time. To deactivate a selector code, either enter the selector code
number preceded by a zero or enter a clear last or clear all control code.
One digit codes
If One Digit Codes is set to true the selector codes are limited to one digit—0 to 9—plus
the quick keys—pound (#) and asterisk (*). These codes are easier to remember and dial.
However, they also have the following limitations:
• Only ten codes are available
• Control codes are not recognized
• The pound and asterisk keys can only be assigned a single digit code
• The system no longer recognizes the 0 form, which deactivates
any established individual path. This means if multiple codes, has been enabled a
previously established path cannot be deactivated.
First code only
If the First Code Only is set to true the DTMF tone detection is disabled after the first valid
code has been received. DTMF decoding can also be disabled by entering the disable
DTMF decoding control code (92), described in the Control Codes section.
Certain circumstances may encourage the disabling of DTMF-tone detection. During
normal operation, DTMF tones in the port’s audio input are decoded at all times. However,
certain audio program sources— such as telephone company commercials—may contain
DTMF tones that are not intended to be interpreted as selector codes, and can
inadvertently reroute the audio path. Certain voices or musical instruments can also fool
the DTMF tone detection circuitry into detecting false DTMF tones.
By disabling DTMF-tone detection after the program feed has been set up, the paths are
not accidentally rerouted. To re-enable tone decoding, hang up and call back again.
Quick codes
These menus define the Touch-Tone keypad’s asterisk (*) and pound (#) keys as quick
keys through the use of quick codes. If a two-digit pair (corresponding to one of the valid
selector codes or control codes) is selected from the menus for the asterisk or the pound,
the DTMF port translates the asterisks or pound’s DTMF tone into that two-digit code. For
