The Sicon-8 is built to keep you on the air.
The Sicon-8 was designed with service in
mind. Our goal is to make it easy and inexpensive
for you to keep the Sicon-8 running in the
field. Wherever possible, chips and exposed
parts are in sockets for easy service.
In addition to sockets, entire PCB sub-assemblies
are used in the Sicon-8. These assemblies
contain parts that are exposed to possible
damage from things like lightning or overloads.
They may also have elements that are not
easily field serviced, like surface-mounted
chips.
By putting exposed or hard-to-replace parts
on sub-assemblies, we give you the opportunity
to stock spares and to easily replace damaged
parts, keeping you operating at all times.
|
| The audio codec PCB is not directly exposed
to the outside world, but
does contain a
surface mounted chip. Other
chips on this
board are socketed for
easy replacement and
the entire assembly comes
off with just two
screws. |
 |
| The Ethernet board and Web Server assembly
is connected to the outside and contains
some SMT chips as seen in the photo to the
right. This assembly also contains parts
that can be field replaced, such as the BEL
transformer and microcontroller. In addition,
the entire board is inexpensive and comes
out with just one screw. |
 |
| All of the relays are mounted on one board
that can be removed with
three screws. Although
the Sicon-8 uses very heavy-duty
relays,
they are directly connected
to the outside
world. After many years
of heavy use, it
is possible for them to
fail or to be damaged
by severe lightning at
any time. By putting
these parts on a chassis
that can be replaced,
you have an inexpensive
and convenient way
to keep your Sicon-8 operational,
even many
years into the future. |
 |
| One of the most commonly damaged parts in
any product is the telephone
interface because
it is often connected to
very long telephone
lines that can induce huge
voltages during
a lightning strike. The
telephone interface
in the Sicon-8 is a field
proven design and
has demonstrated its ability
to survive when
similar products fail.
Usually, when damage
does occur tot he telephone
interface, it
is limited to one of the
inexpensive, socketed
chips. In the event of
a more catastrophic
failure, the entire PCB
is designed for easy
replacement. |
