NP3705 Applied Micro Circuits Corporation (AMCC), NP3705 Datasheet - Page 2

• Manufacturer Part Number: NP3705
• Description: 2.5-gbps Network Processor With Integrated Traffic Manager
• Manufacturer: Applied Micro Circuits Corporation (AMCC)

nP3705
Applications
• OC-12/STM-4 ASAP applications ATM, IMA, FR, PPP, ML-FR/PPP
• Up to 2.5Gbs line cards in access systems - DSLAM, FTTx
• OC-12 SAR, ATM to Packet IWF
• L3-L7 Applications
MISSION
The nP3705, combined with AMCC’s Amur (S1215) channelized framer
and ATM/HDLC/GFP processor extend AMCC’s MISSION multi-service
offering to applications up to OC-12/STM-4 rates. This solution enables
the development of single multiprotocol solutions in place of multiple
single-protocol solutions. The MISSION architecture provides equip-
ment vendors with solutions that enable their customers to save on
both capital and operational expenditures (CapEx/OpEx).

MISSION Software
At the core of the MISSION value proposition is software that imple-
ments a wide variety of protocols on the chip set and enables flexible
potential additions to these base software features. AMCC provides
extensive offerings for the programmable nP37xx Integrated Network
Processors, including both rich off-the-shelf application software and a
complete development environment for extending this application
base if desired.
• The MISSION application software includes ready-to-use Multi-Ser-

vice Switching software – ATM UNI/NNI, Inverse Multiplexing over
ATM (IMA), Multi-Link Frame Relay (ML-FR), Multi-Link PPP (ML-PPP),
Frame Relay and FR to ATM Interworking (FR IWF), MPLS Martini
encapsulation – as well as OEM customer-extensible libraries for the
hardware-resident aspects of higher layer applications such as IPv4
and IPv6 routing, and Layer 2 packet switching.
