5) Select the Passcode by placing a tick in the check box beside the required
password.
6) Apply the changes to the matrix by completing an Apply Changes to System
download.
The selected Passcode is then specific to that TEL-14 interface.
Inward DTMF access
DTMF Access allows combinations of DTMF tones that are pre-assigned with specific
meanings to have access to the Eclipse HX system. The Assign DTMF Access field within
the Advanced Setting screen of a telephone screen allows setting all parameters related to
the DTMF-tone decoding. Each MVX-A16 Crosspoint Card provides sixteen ports, on each
MVX card there are 4 slots where DTMF Daughter boards are required to be fitted before
DTMF-tone encoding and decoding is possible. DTMF decoding is the ability to interpret
DTMF tones. DTMF encoding is the ability to create DTMF tones.
Selector codes are the two-digit numerical codes that outside callers use to access the
system. The codes initiate the specification of audio paths when system is accessed via
DTMF inward access. If the [One Digit Codes] field is set to true, only the ten single-digit
codes [0] through [9] function as selector codes.
If the Multiple Codes (Accumulate) option has been selected in Advanced Settings the
inward DTMF stream may contain multiple selector codes, for example to activate more
than one panel or control. If this is the case it is advisable to separate the selector codes
by placing a space in the source string to ensure that selector codes after the first are
correctly identified.
Note: The characters used to specify a space or pause between codes may vary with the
equipment calling into the Eclipse HX system. Consult the manufacturer’s instructions for
details.
Control codes are codes that perform specific functions, including:
00 - Clear Last Entry—This code clears the paths that were activated by the last selector
code entry. If [00] is entered twice, the paths that were activated by the last two selector
code entries clear, and so on.
91 - Send Call Signal—This code sends a call from the port to the matrix as if a call signal
was sent by an external device connected to the port.
92 - Disable DTMF Decoding—This code turns off DTMF decoding. This may be desirable
because certain program sources may contain DTMF tones not intended to be interpreted
as selector codes, and that can inadvertently reroute the audio path. For further
information First code only
99 or 099 - Clear All—Either of these codes clear all currently active talk and listen paths.
Prompt tones are tone sequences that the MVX-A16 sends to the user. The MVX-A16
issues the following four distinct prompt tone sequences:
Access Code Request—Indicates that the system is ready for an access code to be
entered. If the system does not recognize the entered access codes, it repeats the access
code request prompt. The number of attempts to enter the access code is limitless. The
prompt consists of a low tone followed quickly by a higher tone. The sequence is quickly
repeated three times.
Access Granted—Indicates that the system has acknowledged the access code and that
access to the Eclipse HX matrix has been granted. The prompt consists of four tones,
each increasing in pitch and immediately followed by a ready prompt.
