1-2 Overview MPW-1 MP-4100 Ver. 2.0
MPW-1 is offered in two models with similar characteristics, which differ only in
the type of interfaces supported by the external Fast Ethernet ports:
• MPW-1/UTP: has three 10/100BASE-TX interfaces terminated in RJ-45
connectors
• MPW-1/SFP: has three sockets for Fast Ethernet SFP optical transceivers. RAD
offers several types of SFPs capable of meeting a wide range of operational
requirements.
Applications
MPW-1 can provide transport services even in a Megaplex-4100 without GbE
ports (that is, Megaplex-4100 equipped with CL.1 or CL.1/155 modules). A typical
application of this type is shown in
Figure
1-1
. In this application, the legacy
traffic from TDM I/O modules intended for transport over the PSN is connected to
the MPW-1 internal DS1 ports, using the desired cross-connect mode (DS0 or
DS1). The traffic is then packetized to create data streams in accordance with the
desired pseudowire protocols (TDMoIP, CESoPSN, SAToP, or HDLCoPSN),
independently selectable for each pseudowire. The resulting data streams are
sent via the external Fast Ethernet ports of the module, for routing to the desired
destinations, where each stream is converted back to the original TDM stream.
Figure
1-1. Basic MPW-1 Application (Megaplex-4100 without GbE Ports)
When the Megaplex-4100 has CL modules with GbE ports, for example, CL.1/GbE
or CL.1/155GbE, packetized traffic can also be sent via any bridge port on any
module installed in the chassis (see description of available bridge ports and
Ethernet services in the
Megaplex-4100 Installation and Operation Manual
).
Figure
1-2
shows a typical application for a Megaplex-4100 equipped with
CL.1/GbE modules. In this application, pseudowires are routed to the PSN through
the GbE ports located on the CL.1/GbE module (this capability is in addition to the
local Fast Ethernet ports).
