Parallel TDM and Ethernet processing

The Megaplex-4100 features dual-star

connection architecture with hybrid TDM-

Ethernet modules, which allow native TDM and

Ethernet traffic handling with minimal

encapsulation delays and zero bandwidth

overhead.

Ethernet traffic is handled by a multiport

Gigabit Ethernet aggregation engine, designed

for Carrier Ethernet capabilities, such as flow-

based or port-based traffic management,

performance monitoring and Ethernet OAM.

Ethernet traffic can be terminated by any of the

following:

•

Fast Ethernet ports located on I/O modules

•

Internal Ethernet ports of I/O modules

•

Gigabit Ethernet ports

•

Ethernet over SDH/SONET

TDM traffic can be cross connected at a DS0

level, DS1 (framed/unframed) level, or SDH/

SONET (high/low order) level, with per-port

cross connect operation mode selection.

DS0 cross connect

The Megaplex-4100 features an internal DS0

cross connect matrix of up to 7,872 DS0

channels. Traffic from any channel can be cross

connected directly to any other channel.

These capabilities enable the Megaplex-4100 to

function as a service differentiation point at the

central office, handing off TDM voice and data

services to the transport network.

The device can also be deployed at remote

locations or the customer premises to effectively

fan out multiple voice and data services.

Next-generation ADM terminal

The Megaplex-4100 supports STM-1/OC-3 and

STM-4/OC-12 add/drop multiplexing for

grooming LAN and TDM traffic over SDH/SONET

networks. It eliminates the need 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, the Megaplex-4100 brings Ethernet

economics and packet switching efficiency to

existing SDH/ SONET infrastructure. It enables

utilities and other private fiber network owners

to reduce both OpEx and CapEx, while service

providers can leverage existing equipment to

support clear channel data streams and the

latest high bandwidth services.

Ethernet traffic can be mapped into

n x VC-12/VC-3/VC-4 or n x VT 1.5/STS-1/STS-3C

virtual containers.

Part of the AXCESS+ portfolio of multiservice

access and First Mile solutions, the Megaplex-4100

is a carrier-class, high capacity multiservice access

concentrator, for transporting legacy and next-

generation services over fiber or copper PDH/SDH/

SONET, or over packet switched networks (PSN).

Its ability to handle a broad range of Ethernet,

data and voice services, as well as a large variety

of network technologies in a single compact

managed node, makes the Megaplex-4100 an

ideal core/edge solution for carriers and service

providers. It also provides a perfect fit for large

enterprises, utilities and transportation

companies, who require an efficient way to

transport and provision multiple legacy and next-

generation services over their high capacity pipes.

As a multiservice access node, the Megaplex-4100

provides an efficient and cost-effective solution for

integrating various interfaces, data rates and user

services. These include Fast Ethernet and Gigabit

Ethernet as well as low speed sub-64 kbps data,

serial n x 64 kbps data, high speed data up to

STM-4/OC-12, digital voice, analog voice, ISDN, and

additional industry specific interfaces.

Furthermore, the Megaplex-4100 functions as a

carrier-class TDM and Ethernet aggregator, as well

as a high capacity DS0 cross connect, as detailed

below.
