Chapter 3. CABLES
AND
CONNECTIONS
3.1
Overview
All
cables
for
connecting
the
CRS
‐
311
1:1
Redundancy
Switch
within
the
system
or
to
the
CDM
‐
Qx/QxL
and
SLM
‐
5650/5650A
modems
are
available
from
Comtech
EF
Data.
These
cables
can
be
ordered
at
the
same
time
the
order
is
placed
for
the
CRS
‐
311.
Leave
the
CRS
‐
311
and
all
modems
powered
off
until
all
connections
are
ready.
The
illustrations
featured
throughout
this
chapter
provide
cabling
configuration
examples
for
RMI
or
TMI
interfaces
–
i.e.,
the
interconnection
of
a
Redundant
Modem
to
a
Switch
RMI
module,
or
the
interconnection
between
a
Switch
TMI
module
and
a
Traffic
Modem.
This
chapter
also
outlines
the
step
‐
by
‐
step
process
for
connecting
a
variety
of
CRS
‐
311
and
modem
control,
M&C,
or
data
traffic
configurations.
You
must
properly
attach
all
required
cabling
once
the
CRS
‐
311
and
all
the
modems
are
mounted.
In
most
cases
the
modem
accepts
the
male
end
of
the
cable,
while
connectors
on
the
RMI
or
TMI
module
accepts
the
female
end
of
the
cable
in
the
module
section
labeled
“Modem
Interface.”
See
the
subsections
in
Sect.
1.3
CRS
‐
311
Physical
Features
for
detailed
information
on
these
interfaces.
When
fabricated
by
the
user,
the
cables
required
between
each
modem
and
CRS
‐
311
RMI
or
TMI
plug
‐
in
module
should
be
of
shielded,
twisted
‐
pair
construction,
with
the
grounded
shield
bonded
to
the
back
shell.
Use
the
pinout
and
connection
information
specified
in
Appendix
A.
CABLE
DRAWINGS
to
correctly
wire
all
control
or
data
cables.
