PRODUCT BRIEF
ADVAPNRCEELDIMCIONNAFRIYDENTIAL XRT95L53 EXtendAR-48M
OC-48 ETHERNET/SONET MULTI-SERVICE FRAMER PROCESSOR
FEBRUARY 2005
GENERAL DESCRIPTION
EXtendar 48M (XRT95L53) is a highly integrated OC-
48/STM-16, Quad OC-12/STM-4 & OC-3/STM-1
Multi-protocol Framer processor. This device
combines standard OC-48/STM-16, Quad OC-12/
STM-4, OC-3/STM-1 SONET framer functions with a
flexible packet interface as well as a range of framing
and encapsulation techniques integrated on a single
chip. EXtendar 48M supports Generic Framing
Procedure (GFP) in combination with Virtual
Concatenation & LCAS, LAPS, POS, ATM and DS3
capabilities configurable on a per-channel basis.
EXtendar 48M is the industry's first device to
integrate 48 DS3/Fractional DS3 framers on a single
chip. EXtendar 48M, in addition to the SONET OC-
48/OC-12/OC-3 interfaces, supports OIF compliant
SPI-3 interface with optional support for Exar's
proprietary G-header interface. Using this industry
first G-header interface, EXtendar 48M provides
framing and encapsulation support for RPR, MPLS or
proprietary client data that need to be transported
over SONET. The unique combination of flexible
packet framing and encapsulation features combined
with optimal SONET transport capabilities make
EXtendar 48M an ideal solution for Multi-service
SONET transport, Core as well as DWDM systems.
APPLICATIONS
