rev
Xstreams
have
the
ability
to
provide
power
on
the
ISDN
S
interface
(to
power
a
telephone
for
example).

of
the
ISDN
S
interface
on
these
units
can
supply
‐
48
VDC
to
an
external
device
such
as
a
telephone.
This
can
be
disabled,
which
is
the
default
setting.

IMPORTANT TIP!
Leave this power source disabled unless you know how you will be using it.
Under no circumstances should this power be enabled if the "S" interface will be shared with
a Zephyr Classic or ZephyrExpress.

also
requires
specialized
tools
and
