Note: When using the TEL-14 with a speaker station, keep the panel mic gain low. In
general, keep all gain controls set to a level which is acceptable, but not excessive.
DESCRIPTION
The TEL-14 telephone interface can be installed in an IMF-3 or IMF-102
interface frame.
The TEL-14 allows two standard 2-wire POTS (Plain Old Telephone Service)
telephone lines to be connected to ports in the Eclipse matrix. The TEL-14 can
answer an incoming call automatically ("auto-answer") after either 1 or 4 rings,
and it can be configured to send a call signal whenever it answers a call. The
TEL-14 can be configured to be accessible to intercom station operators, or only
to outside callers.
The front panel features for each telephone line a "ring/off-hook" LED, a "hook"
button, a "send level" LED, a "send volume" control, a "receive volume" control,
an "auto gain adjustable" LED, an "auto gain" button, an "auto gain fixed" LED,
an "auto answer" LED, and an "auto answer" enable button. For more details see
the "Controls and Indicators" section, below.
The TEL-14 occupies one slot in an interface frame. The TEL-14 provides
transformer isolation between each telephone line and the matrix. The TEL-14
includes a "normally open" relay ("A" and "A1" contacts) for each line that closes
when the line is in use (off hook). Connections to the matrix are via RJ-45
connectors, and connections to the telephone line and external relay connections
are via DB-9M connectors. A secondary telephone set may be connected in series
with each TEL-14 line. Clear-Com provides DB-9F to RJ-11 adapters (CC#
770025) that allow the use of common RJ-11 telephone jacks and cords.
