Product Brief
VersaNode
155/622 Mbps Multi-Protocol Metro Access Solution
Features
VersaNode is a highly integrated MultiProtocol Access solution supporting traditional
SONET/SDH linear and ring architectures as
well as emerging packet rings. VersaNode is
equipped with multiple voice, leased line and
data service interfaces such as 10/100
Ethernet, Gigabit Ethernet, SPI-3 CoProcessor, DS1/E1, and DS3/E3. The
SONET/SDH interfaces support redundant
OC-3/12 or STM-1/4 lines. Data mapping,
such as Ethernet over SONET/SDH (EoS), is
supported through Virtual Concatenation (VC)
with Link Capacity Adjustment Scheme
(LCAS), with simultaneous use of mixed High
Order (STS/VC paths) and Low Order (VT/VC
paths).

• Up to 2 Gigabit Ethernet via GMII
• Up to 8 Ethernet / Fast Ethernet via
SS-SMII
• OIF compliant SPI-3 connection to
packet co-processor
• 28 x DS1/E1
• 3 x DS3/E3
• STS-3/AUG-1 or STS-12/AUG-4 byte

• Dual SONET/SDH line interface supporting 1+1 and 1:1 linear APS, High and Low
Order UPSR/SNCP and Resilient Packet Rings
• Full SONET/SDH Transport Overhead (TOH) processing, with configurable serial
extraction and insertion of full TOH or only DCC portion
• SONET/SDH High and Low Order path termination
• TU-3/TUG-3 and TUG-2/TUG-3 support
• Serial POH extraction and insertion
• SPI-3 Co-Processor port supporting Layer 2/3 packet processing
• Connection to Ethernet ports and SONET/SDH data encapsulation channels
• Supports RPR, client aggregation, Class of Service
• Flexible mapping of data signals into any Contiguous or Virtual Concatenation of
VT1.5/STS-1/STS-3c or VC-12/VC-3/VC-4 containers

Product Brief
Description
With DS1/E1, DS3/E3 and Ethernet client interfaces, a packet co-processor port, flexible mapping, and redundant SONET/SDH line interfaces
supporting linear and ring based optical networks, VersaNode integrates the technologies required to simplify the development of next generation
multi-service and multi-protocol access solutions.
The internal Time Slot Assigner provides complete flexibility in the mapping of client signals into appropriate high or low order transport containers.
HDLC and GFP encapsulation along with Virtual Concatenation and LCAS enable the efficient delivery of Ethernet and other data services. The
packet co-processor port provides the flexibility to support the evolution of packet grooming and aggregation at the edge as well as packet based
transport networks such as Resilient Packet Rings.
