Chapter 1
Introduction
1.1 Overview
This manual describes the technical characteristics, applications, installation and
operation of the MPW-1 pseudowire access gateway I/O module for the
Megaplex-4100 Next Generation Multiservice Access Node.
MPW-1 operates as a pseudowire server for TDM traffic (E1, T1, SHDSL, ISDN,
high-speed and low-speed data, voice) received via the internal Megaplex-4100
TDM buses from other I/O modules installed in the same chassis. MPW-1
performs the following tasks:
• Interfacing to the Megaplex-4100 internal TDM buses (equivalent capacity of
256 timeslots, or eight 2.048 Mbps streams).
• Conversion between TDM and pseudowire packet formats. The conversion
parameters are controlled by defining pseudowires (see
Megaplex-4100
Installation and Operation Manual
for details), and can be optimized for the
specific end-user’s equipment and the application requirements.
• Forwarding the pseudowire packet streams, either directly to a PSN (through
the MPW-1 external Fast Ethernet ports, or via its internal Fast Ethernet
ports), for forwarding over any bridge port within the Megaplex-4100 (refer
to the
Megaplex-4100 Installation and Operation Manual for details). Each
pseudowire can be forwarded to the desired endpoint through the
packet-switched network. Both UDP/IP and MPLS/ETH networks are
supported. The user can also specify forwarding and priority/quality of service
parameters.
Installing a MPW-1 module enhances Megaplex-4100 capabilities and services by
enabling the transport of legacy TDM traffic from other modules over Ethernet,
IP, and MPLS packet-switched networks (PSNs), even when the Megaplex-4100 is
not equipped with CL modules with GbE ports. MPW-1 supports the TDMoIP,
CESoPSN, SAToP and HDLCoPSN pseudowire protocols.
For details regarding the integration of MPW-1 modules in Megaplex-4100 systems
and systems applications, refer to the

Product Options
MPW-1 is a pseudowire access gateway module with two types of ports:
• Internal TDM (DS1) ports, for TDM traffic from the internal TDM buses of the
Megaplex-4100
• Internal and external Fast Ethernet ports, for the packetized data streams.
