4.5. Connecting the phone cables:
You may use one of the phone interfaces,
either
FXS
or
FXO. For connection, BYTTON HSDPA is
shipped with a flat telephone cable, wired on both side with male RJ11 connectors.
Connecting the telephone cable for FxS interface
Connect the telephone cable with
one of the end to the FXS connector
of BYTTON and the other end to an
analog trunk
of PBX.
Should the phone exchange have
terminal trunks not equipped with RJ-
11 connectors, you must connect the
two middle wires of telephone cable
directly to internal connector of the
PBX exchange.
Alternately, you may connect the
telephone cable with one of the
end to the FXS interface of
BYTTON HSDPA and the
opposite end directly to a standard
(fixed) phone.
In this case you won’t have the
routing facilities of the phone
exchange, but you still be able to
make voice calls while transferring
files or browsing the Internet.
Note: BYTTON HSDPA features analog phone interfaces, so it must not be connected to an ISDN
interface (digital trunk) of PBX exchange.
For connection to an ISDN exchange you should use
wireless equipment specially designed for ISDN phones.
Improper installation of BYTTON HSDPA
equipment might lead to damage of BYTTON or PBX. (If you join a local subscriber line of PBX exchange
to the FXS connector of BYTTON then both equipment will generate current into the connection cable, so
the Bytton router and PBX the exchange could be damaged).
