Next Generation Multiservice Access
Megaplex-4100 an ideal core/edge
solution for carriers and service providers.
It also provides a perfect fit for large
enterprises, utilities and transportationcompanies, that require an efficient way
to transport and provision multiple legacy
and next-generation services over theirhigh capacity pipes.

CARRIER-CLASS SERVICE PROVISIONING
Megaplex-4100 offers carrier-classprovisioning features, including end-toend path management, to ensure
continuous service availability. Advanced
SNMP management capabilities enable
Megaplex-4100 to control and monitor all
network elements: SDH/SONET access andring units, as well as remote POP and firstmile broadband access feeders and CPEs.

MARKET SEGMENTS AND TYPICALAPPLICATIONS

Megaplex-4100 can terminate TDM and
Ethernet traffic carried over E1/T1 links,
fiber or SHDSL, as well as over VCGs in
STM-4/OC-12 and STM-1/OC-3 links. This
traffic can then be switched either to adifferent PDH/TDM trunk or to the Gigabit
Ethernet or Fast Ethernet ports.
Various users can benefit from thissolution:

Megaplex-4100 can be managed by the
SNMP-based RADview-EMS multiplatform
Element Management System and
RV-SC/TDM service management
application. Alternatively, configurationand monitoring can be performed either
via Telnet or an ASCII terminal using RAD
command line interface (CLI).

Megaplex-4100 node can be used in thefollowing applications:

SMOOTH MIGRATION FROM TDM TO
PSN

Multiservice access over SDH/SONET
networks with a single box solution for
U&T companies (see Figure 1).
An aggregation access solution for
carriers and service providers, totransport TDM and Ethernet traffic
over copper and fiber, towards
SDH/SONET or packet-switched
networks (see Figure 2).

One of the benefits of command line
interface is that databases and scripts ofcommonly used commands can be easily
created and applied to multiple units.



SDH/SONET customers who need tocontinue using their network while
maximizing bandwidth utilization

Subscribers with mixed Ethernet andTDM services



Subscribers looking for a future-proof
migration path to IP connectivity

Dual network owners using

Megaplex-4100 provides legacy services
over packet switched networks, using a
dedicated module to convert data stream
from other modules to Ethernet, IP or
MPLS packets with TDMoIP, CESoPSN,
SAToP, and HDLCoPSN pseudowire
technologies. The device’s
hardware-based architecture provides arobust pseudowire solution with minimal
processing delay.

As a multiservice access node,
Megaplex-4100 provides an efficient andcost-effective solution for integrating
various interfaces, data rates and user
services. The available interfaces and the
maximum number of ports per chassis are
as follows:

and STM-1/OC-3 add/drop multiplexing forgrooming LAN and TDM traffic over
SDH/SONET networks. It eliminates theneed for separate ADM and multiplexer
units for private networks where voice,
Ethernet and data services are required.
By implementing VCAT protocols to carry
Ethernet traffic efficiently and minimize
wasted bandwidth, Megaplex-4100 brings
Ethernet economics and packet switchingefficiency to existing SDH/ SONET
infrastructure. It enables both OpEx and
CapEx reduction, leveraging existing
equipment to support clear channel data
streams and the latest high bandwidth
services.

Next Generation Multiservice Access

CARRIER-CLASS RELIABILITY
The modular, distributed architecture of
Megaplex-4100 enables redundancy at
different levels of the network andprovides a resilient system with no single
point of failure. Hardware redundancy isprovided through an optional redundant
power supply and Common Logic modules,
with switchover to the backup Common
Logic links within 50 msec.
The SDH/SONET system employs APS 1+1
protection, as well as subnetwork
connection protection (SNCP for SDH and
UPSR for SONET) for path protection. The
Ethernet GbE ports feature link protection
mechanisms using LAG and VCG protection
over SDH/SONET. In addition, any E1/T1
stream can be protected using various
mechanisms over any interface.
In addition to connecting to standard
SDH/SONET rings, Megaplex-4100 can beused to create E1, T1, TDM over SHDSL,TDM over Fiber, or a mix of ring
topologies. Megaplex-4100 provides aperfect solution for combining low-rateservice provisioning and ring protection.
MODULARITY AND FLEXIBILITY
Megaplex-4100 is available as a 4U-highchassis providing slots for up to 2 AC or
DC power supplies, 2 common logic and
10 I/O modules. This allows for a “pay as
you grow” approach and enables CapEx
optimization.
Common Logic
The Common Logic (CL.2) module controls
the Megaplex operation and is theinterface for its configuration andmanagement.
CL.2 features dual-star connection
architecture with hybrid TDM-Ethernet
modules. This allows native TDM and
Ethernet traffic handling with minimal
encapsulation delays and zero bandwidth
overhead.

user service requirements. Up to 10 I/O
modules can be installed in the chassis. In
addition to its own modules,
Megaplex-4100 supports selected modules
operating in the Megaplex-2100/2104
chassis. Table 1 lists the system and I/O
modules available for Megaplex-4100. For
