What is OTN?
• Open Transport Network (OTN) is a fiber optics based multiplexer for voice, data, video and LAN applications
• OTN provides pre-allocated services for applications
• OTN is a distributed system allowing dynamic switching for video and audio
• OTN has built-in redundancy
• OTN is not a bandwidth on demand, but dedicated bandwidth at all times regards of system loading.
• OTN is not protocol, but rather physically oriented to best integrate easily with applications equipment
• OTN provides the best features of TDM and Ethernet in the same product platform

Who are the customers?
• Vast coverage
• Multiple services
• Non-stop environment

What is the common element in these areas?
• Mixed service requirements
• Very high reliability, redundancy requirements
• High bandwidth requirements
• Operations critical, 24x7x365 system operations
• Security aspect
• Need for low cost of ownership
• Industrial strength equipment
• Environmental conditions
• Dedicated, always available communications
• Network expansion/alterations without disruption
• Can span long distances

OTN Management System (OMS)
• Configuration of Hardware– Nodes– Transceivers– Interface Cards
• Configuration of Services• Monitoring + Logging + Reporting• Alarm Management• Visualizing Network Recovery• OMS can be connected to any of the
nodes in the network• Manages all types of OTN networks• Multi user, client-server technology• Manages multiple subnetworks (rings)
simultaneously • Runs on standard PC under Windows
NT/2000/XP• Open: alarm export via SNMP or serial
link

Video over OTN
• OTN behaves like a distributed video matrix
• Features and video image quality of analog CCTV
• Reliability and flexibility of digital fiber transmission
• OVS provides a platform for Multi-vendor integration
• Based on standards:– OPC (OLE for Process Control)
– Microsoft DCOM
• Open to non-standard CCTV equipment through– Universal Protocol Handler
– Published serial protocol

Just Imagine a Network
• Like a private superhighway (150 - 600 - 2500 Mbps)
• That never goes down
• Never goes out of date (future proof)
• Never gets in the way (transparent)
• Spans any distance (>1000 km)
• Hooks up what you like (investment protection)
• Takes a day to install (plug & play)
• Is child’s play to manage
• And easy to afford
