Description
The
MARS2G5-T-Pro
SONET/SDH
overhead
and
path
processor
provides
a
versatile
solution
for
quad
OC-3,
quad
OC-12,
and
for
single
OC-48
linear
and
ring
datacom/telecom
applications
.
Constructed
using
Agere
Sys-
tems'
state-of-the-art
CMOS
technology
(COM2
CMOS
modular
process),
this
device
incorporates
integrated
SONET/SDH
section/line/path
termination, pointer
processing,
and
cross
connect
blocks
.
Communication
with
the
MARS2G5-T-Pro
device
is
accomplished
through
a
generic
microprocessor
interface
.
The
device
supports
separate
address and
data
buses
.
With
this
device,
support
for
different
types
of
applications
for
OC-3/OC-1
2/0C-48
data
equipment
is
possible,
enabling
dramatic
system
cost
reduction
and
the
ease
of
development
of
extremely
competitive
solutions
.
The
interface
rates
supported
are
STS-48/STM-16,
quad
STS-1
2/STM-4,
and
quad
STS-3/STM-1
.
The
concatena-
tion
levels
supported
by
this
device
are
STS-1, STS-3c,
STS-6c, STS-9c,
STS-12c,
STS-15c,
. . . ,
STS-45c, and
STS-48c
.
