Serial
Connection
Equipment
The
FSIP
supports
synchronous
serial
connections
at
Ti and El speeds
the actual
speed
depends on
the type of
electrical
interface
used
the distances
the signals
must
travel
and
the configuration
of
other ports
on
the
same
FSIP module
In general
you
should
use
BIA/TIA-232
for speeds of
64kbps
and below
and
use
X.21
EIAITIA-449
V.35
or
EIA-530
for
higher
speeds
See
the section
Configuring
the
FSIP
in the chapter
Maintaining
the
Router
The
universal
FSIP
ports
for
all
interface
types
are
60-pin
D-shell
receptacles
Each
port
requires
serial
port
adapter
cable
to
connect
to
the external
network
or connection
device
Universal
Serial
Cables
On
data
communications
ports
the universal
serial
port
adapter
cable
determines
the
electrical
interface
type
and
mode
of the port
All universal
serial
cables
use
60-pin
D-shell
plug
at
the router
FSIP
end
The
network
end
of each
cable
provides
the standard
connector
used
with
each
respective
interface
type
See
Figure

Cables
for
all
data
communications
interfaces
except
EIA-530
are available
in
DTE
mode
with
plug
at
the
network
end
or in
DCE
mode
with
receptacle
at
the

end
The
