Preparing
Network
Connections
To
use
the optical
bypass
feature
available
with
multimode/multimode
CX-FIP-MM
and
single-mode/single-mode
CX-FIP-SS FDDI
interfaces
you
need
an
optical
bypass
switch
DIN-to-mini-DIN
control
cable
CAB-FMDD
for connecting
the switch
is
included
with
each
of these
FIPs
To
use
low-speed synchronous
serial
interface
you need
synchronous
modem
or
CSUIDSU
to
connect
to
the
network
Most
modems
require
an
EIA/TIA-232
DTE
connection
To
connect
serial
adapter
cables
to
remote
devices
that
use
metric
hardware
replace
the
factory-installed
4-40 thumbscrews
on
the
network
end
of the cable
with
the
M3
metric
thumbscrews
that
are included
with
all
serial
port
adapter
cables
To
connect
serial
port
to
Ti
network
you need
Ti
CSUIDSU
that
converts
the
High-Level
Data Link
Control
HDLC
synchronous
serial
data
stream
into
Ti
data
stream
with
the correct
framing
and
ones
density
The
term
ones
density
refers
to
the
fact
that
some
telephone
systems
require
minimum
number
of
bits
per time
unit in
data
stream
Several
Ti
CSUIDSU
devices
are
available
as additional
equipment
and most
provide
either
V.35
EIA/TIA-449
or
EIA-530
electrical
interface
to
the
system
Ti
is
the
term
for
digital
carrier
facility
used
for transmitting data over
telephone
network
at
.554
Mbps
Ei
is
the
European
equivalent
of
Ti
and
has
line
rate
of 2.048
Mbps
To
connect
HSSI
port you need
DSU
that
can
process
data
at
speeds
appropriate
for the
service
to
which
you
will
connect
T3
45
Mbps
E3
34
Mbps
or
SONET
STS-l 51.84
Mbps
and
HSSI
interface
cable
CAB-HSIi
to
connect
the
DSU
with
the
HIP
T3
also
luown
as
DS3
or
digital
signal
level
is
the
U.S
standard
for
digital
carrier
facility
used
for transmitting data over
telephone
network
at
44.736
Mbps
T3
is
equivalent
to
28 Tl
1.544
Mbps
interfaces
E3
is
the
European
equivalent
of
T3
that
operates
at
34
Mbps
SONET
Synchronous
Optical
NETwork
is
an
international
standard
ANSIJCCITT
for
standardizing
the
use
of
optical
communications
systems STS-i Synchronous
Transport
Signal
level
is
the basic building
block
signal
of
SONET
level
is
51.84
Mbps
Faster
SONET
rates
are defined
as
STS-n
where
is
multiple
of 51.84
Mbps
For example
the
rate
for
SONET
STS-3
is
155.52
Mbps
times
5i.84
Mbps
To
connect
two
routers
directly
back
to
back
between
HSSI
ports
you need
null
modem
cable
CAB-HNUL
The
two
routers
must be
in the
same
location
and
can
be
two
Cisco
75i3
routers
two
Cisco
7000
series
routers
or
one
of
each
both
routers
must have
HSSI
port
available
ATM
Connection
Equipment
All
AlP
ATM
interfaces
are full-duplex
You
must
use
the appropriate
ATM
interface
cable
to
connect
the
AlP
with
an
external
ATM
network
The
AlP
provides
an interface
to
ATM
switching
fabrics
for
transmitting
and
receiving
data
at
rates
of
up
to
i55
Mbps
bidirectionally
the actual
rate
is
determined
by
the physical
layer interface
module
PLIM
The
AlP
can
support
PLIMs
that
connect
to
the following
physical
layers
TAXI
