1
Supports a range of flexible encapsu-
lation & framing features including
GFP -F, LAPS, PPP/HDLC, BCP and
ATM
Supports the latest standards of GFP -
F and -T and provides flexibility of dif-
ferent encapsulation /framing features
on a per channel basis
Supports a wide range of framing and
encapsulation features ensuring the
effective mapping of different types of
client data
2
Supports 48 DS3 and sub-rate DS3
framers on a single chip
Supports a unique combination of DS3
framer functionality coupled with
advanced packet encapsulation and
SONET framing functions in a single
chip
High level of integration reduces the
total system BOM cost
Single device enables multiple applica-
tions
3
Supports High order and Low order
virtual concatenation capability for 64
VC channels with LCAS
Supports both HO order Virtual con-
catenation as well as VT mapping sup-
port in a single chip.
Enables the optimal utilization of
SONET bandwidth for various types of
client data as well as ensures the
dynamic allocation of bandwidth to
meet service-level requirements.
4
Supports a proprietary G-Header
interface compatible with OIF compli-
ant SPI-3 interface
Enables support for RPR , MPLS and
other proprietary client data types that
need to be optimally transported over
SONET.
Promotes flexibility and ease of use
spanning multiple applications
