TDM to Ethernet

Ethernet is the technology of choice for networking requirements and recent Ethernet standardization efforts have focused on improving Quality of Service (QoS) and Operation Administration and Management (OAM). These improvements retain Ethernet’s strengths and also address its weaknesses.

As a result, Industrial networks, traditionally dominated by SONET/SDH and other proprietary technologies, are rapidly migrating to Ethernet. Ethernet’s simplicity and interoperability (plug-and-play & universal connectivity), combined with cost efficiencies (low replacement costs & future-proof scalability), will accelerate this migration.

Benefits of JumboSwitch vs. SONET/SDH

• 
  Bandwidth Efficiency
  The JumboSwitch GigE platform offers the latest advances in QoS, Traffic prioritization and multi-service capabilities of Ethernet.
• 
  Unlike SONET/SDH
  Traditionally, where every application has its own dedicated time slot regardless of traffic, a JumboSwitch Ethernet backbone supports multiple applications over one shared network.
• 
  Flexible Topologies
  The JumboSwitch supports ring, mesh, string and star configurations whereas SONET/SDH only supports ring topologies.
• 
  Protection Bandwidth
  In most SONET/SDH deployments, the protection bandwidth is often wasted during normal operation. By supporting Multiple Spanning Tree Protocol IEEE 802.1s (MSTP), the JumboSwitch maximizes bandwidth use by allowing service subscription over the protection bandwidth.
• 
  Plug-and-Play Simplicity
  Deploying an Ethernet-based solution such as the JumboSwitch is relatively easy compared to SONET/SDH, which can take months of costly planning and configuration.
• 
  Future Proof Investment Protection
  With its migration to 10GigE, the JumboSwitch solution offers invaluable investment protection. Users can upgrade to 10GigE by simply changing the main module. Of course, this upgrade will support interoperability with all existing interface cards, chassis and power supplies.
