RJ11
(ULP

An
RJ11
6
‐
way
connector,
as
shown
and
described
below,
serves
as
a
means
of
supplying
and
controlling
DC
power
to
the
modem.
The
power
supply
voltage
(VCC)
required
by
the
modem
is
in
the
range
of
6.5
to
10VDC
(9.8
to
13.9VDC
can
be
ordered
upon
request).
The
power
supply
has
to
be
a
single
voltage
source
capable
of
providing
a
current
peak
during
an
active
transmission.
The
uplink
burst
causes
strong
ripples
(drop)
on
the
power
lines.
Application
of
the
power
supply
voltage
to
PIN
1
does
not
switch
the
modem
on
by
default.
The
user
has
to
use
whatever
wake
‐
up
source
once
the
modem
is
powered.
