Description
HSSI
Interface
Processor
The
HIP
shown
in Figure
1-17
provides
full-duplex
synchronous
serial
interface
for transmitting
and
receiving
data
at
rates
of
up
to
52
Mbps
HSSI
recently
standardized
as
EIAITIA-612/613
provides
access
to
services
at
T3
45
Mbps
E3
34
Mbps
and
SONET
STS-1
51.82
Mbps
rates
The
actual
rate
of the interface
depends on
the external
DSU
and
the type of service
to
which
it
is
connected
The
default
HIP
microcode
resides
on
an
EPROM
in
socket

HSSI
Interface
Processor
The
HIP
interface
port
is
50-pin
SCSI-Il-type
receptacle
however
you need
an
HSSI
interface
cable
to
connect
the
HIP
with
an
external
DSU
Note
Although
the
HSSI
port
and
cable
are
physically
similar
to
SCSI-il
format
the
HSSI
specification
is
more
stringent than
that
for
SCSI-il and
we
cannot
guarantee
reliable
operation
if
SCSI-Il
cable
is
used
null
modem
cable
allows
you
to
connect
two
collocated
routers
back
to
back
to
verify
the
operation
of the
HSSI
interface
or
to
build
larger
node
by
linking
the routers
directly
For

of
HSSI
network
and
null
modem
connections

to
the section
HSSI

Router
The
appendix
Cabling

There
are
no
restrictions
on
slot
locations
or
sequence
you
can
install

in
any
available
