Intercom Station Telephone Access Mode
In “intercom-station telephone access” mode, a call on a TEL-14 line can be
answered by any intercom station with a selector key assigned to a TEL-14 port
label. Intercom stations can originate a call by using the "dial phone" mode.
If the call must originate at another station model, then this station must have a
key programmed to activate a DTMF sequence. Another way to arrange this is
for the operator to have access to a standard telephone set connected with the
TEL-14 line (for further information, see "Manual Call Screening Operation"
below). The default settings of the TEL-14 allow “station access” mode.
Self-Service Dial-In Mode
In “self-service dial-in” mode (also referred to as "telephone IFB" mode), the
TEL-14 will answer automatically whenever outside callers dial in. The caller can
be automatically connected to a preset party-line, station, or program feed. Using
"direct inward access" the caller can specify paths within the matrix. Auto
disconnect will release the line automatically after the caller hangs up.
To set the TEL-14 controls for self-service dial-in mode:
1. Set the "splash tones" option switch (S1-7) to OFF. This will prevent the
TEL-14 splash tones from sounding. The matrix will supply tones to prompt
inward dialing.
2. Set the remaining option switches to ON, the factory set position, or as
otherwise required.
Manual Call Screening Mode
In “manual call screening” mode, incoming calls can be answered by a "master"
operator with physical access to the TEL-14 "hook" button. A standard
telephone, wired in series with the TEL-14, is used to initially pick up the call.
When the telephone has been wired in series with the TEL-14, picking it up will
not cause the interface to go off-hook, nor will this interfere with a call already in
progress.
When the call is complete, the destination station operator can inform the master
operator, and the master operator can hang up the TEL-14 using the "hook"
button. If the "auto-disconnect" option switches are set, the TEL-14 will release
the telephone line automatically when the caller hangs up. The telephone line
will not be released if the talk path to the TEL-14 port is deactivated. This
prevents a station operator from inadvertently disconnecting an in-bound caller.
The destination station operator can also use the “remote telephone-line release”
feature to hang up the phone.
