Description
The
TC1900/TC1901 "Quick-Talk" Phone Extender can turn a fiber optic network
or
RS-232 circuit into a voice network simply by plugging a telephone set into an
RJ-11 connector. It is compatible
with most PBXs or Key Systems.
Quick-Talk
is typically used to extend dial-up phone service to remote sites over a fiber
optic or RS-232 circuit. For
example, a user can extend a secured phone link to a remote site via an existing
satellite or microwave RS-232 data connection.
With the optional fiber optic front end, Quick-Talk can extend a phone
line up to 20 miles away.
Quick-Talk
provides 2-wire FXS (foreign exchange subscriber) on the telephone side with
ring down capability and FXO (foreign exchange office) on the PBX side.
When both sides are set to FXS, a "Hot Link" can be
established; when one side lifts up the handset, the other side starts ringing.
Available
in standalone (TC1900S) or rackmount (TC1900R) versions, it is compatible with
all popular types and sizes of fiber optic cable. Diagnostic aids include 16
diagnostic LEDs for indicating power, ring, FXS, FXO, and audio activity. The
TC1900R PC Card version fits into rackmount card cages.
Quick-Talk
is available with RS-232 or
optical interfaces.
The optical interface is available in multimode (850/1300nm) or single
mode (1300/1550nm) versions, with ST or FC connectors. A local dry contact relay
is also provided for external alarm and ringer connection.
Power
is 12VDC or 115/230VAC with an external power cube. Power options include 24VDC
or -48VDC.
Power redundancy is standard.
Electrical connectors are RJ-11 Female for the telephone set, DB9 female
for RS-232.
