TEL-14 TWO-CHANNEL TELEPHONE INTERFACE
"Auto Gain" Status LEDs
These green and yellow LEDs indicate the currently selected
“auto
gain
” mode. The yellow LED indicates that the “adjustable” mode is
selected and the green LED indicates that the
“fixed” mode is selected.
Refer to the previous paragraph for an explanation of these modes.
"Auto Answer" Button
The front-panel
“auto answer” button allows the local user to enable or
disable the TEL-14's auto answering mode. The
“auto answer”
function, in conjunction with the
“auto disconnect” function, allows a
TEL-14 to automatically service incoming calls. An outside caller can
automatically be connected to any matrix audio connection that has
been pre-assigned from the Eclipse Configuration System, such as a
party line or an IFB program feed.
Auto answer is enabled by using the "auto answer" button to turn ON
the auto answer indicator LED. The interface will then automatically
answer incoming calls after either 1 or 4 rings, as set by the "ring
count" option switch. The TEL-14 remembers the setting of the "auto
answer" button when power is turned off.
The
“auto-answer” button can be overridden by the Eclipse matrix to
allow the TEL-14 to auto-answer without the auto-answer button
being set to enable.
This will occur when a TEL-14 is configured in ECS to use Passcodes
set up in the System Preferences
“System Access Codes” tab as DTMF
Passcodes. The use of DTMF passcodes is configured in Matrix
Hardware under Advanced Settings and DTMF Settings as “Enable
Passwords”.
Once a line is auto answered, it can only be released by auto
disconnect, by the "hook" button, or from a matrix station that has
"remote telephone-line release" enabled. Auto disconnect releases
the line when a dial tone, busy tone, reorder tone, or loop current
interruption appears on the line (if not disabled by the auto-
disconnect option switches). The line cannot be released by
deactivating any or all talk or listen paths from the intercom
stations to the TEL-14. Flash hook signals from the matrix will also
have no effect. This prevents intercom station operators from
disconnecting the telephone line when it is in automatic use by
outside callers, or in manual use by an intercom station operator
who has access to the "hook" button.
The "auto answer" button can also be used to initiate an
automatic nulling sequence. Refer to the following section.
"Auto Answer" Status LED
This green LED indicates the currently selected
“auto answer” mode.
If it is lit, the TEL-14 will automatically answer telephone calls. If it is
not lit, incoming telephone calls can only be answered manually.
Refer to the previous paragraph for further explanation of
“auto
answer
” mode.
