Installation and Operation Manual Chapter 1 Introduction

MPW-1 MP-4100 Ver. 2.0 Overview 1-3

The application of

Figure

1-2

also permits users connected to MPW-1 Ethernet

ports access to packet switched networks (PSN), for example, Internet or

metropolitan Ethernet networks, via the Megaplex-4100GbE links.

Another application for a Megaplex-4100 equipped with CL.1/GbE modules is

shown in

Figure

1-3

. In the application shown in

Figure

1-3

, Megaplex-4100

located at Site B does not have without direct access to the PSN: therefore,

pseudowire traffic generated by MPW-1 modules at site B is directed, by internal

flows within the Megaplex-4100, to ASMi-54C SHDSL.bis I/O modules, which

transport the traffic over SHDSL.bis lines to a DSLAM located at the point-of-

presence (PoP). The PSN provides the connection to the GbE ports of the

Megaplex-4100 at Site A, where MPW-1 modules convert the packetized traffic

back to legacy TDM traffic.

The applications shown in

Figure

1-2

and

Figure

1-3

can also be implemented in

Megaplex-4100 with CL.1/155GbE modules. However, CL.1/155GbE modules

support additional capabilities: for example, E1 or T1 traffic received via

STM-1/OC-3 links can be directed to the MPW-1 modules for processing and

transport over PSN.

Another option, illustrated at Site A in

Figure

1-4

, is applicable for Megaplex-4100

connected to STM-1/OC-3 infrastructure, but not to the PSN infrastructure: TDM

services are converted to packet traffic at Site A and transferred over SDH/SONET

using virtual concatenation. The desired bandwidth is specified by configuring a

virtually concatenated group (VCG) using the appropriate type and number of

VCs/VTs, and availability can be enhanced by configuring LCAS. At the desired

location in the SDH/SONET network, the virtually concatenated group is

terminated by a RAD Interface Converter, RICi-155GE, and converted to Ethernet

for transmission over the PSN to Site B, where another Megaplex-4100 with

MPW-1 converts the packetized traffic back to legacy TDM traffic.
