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


Railways, metros, light rails


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• Never goes out of date (future proof)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
