"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.
