User 8: 50 VC-12s/VT2s/VT1.5s
Transport Features: Ethernet Path Protection 6 Mbps
10 Mbps 4 Mbps
4 Mbps
10 Mbps traffic is provided by giving 6 Mbps (3 VC-12) along the blue path and 4 Mbps (2 VC-12) along the red path between the ingress and egress node. In case of failure as shown in the figure the bandwidth would come down to 4 Mbps without the traffic being hit This would provide protection for at least 4 Mbps of traffic even when there is a fiber cut and hence a cheaper solution compared to full protection but clear differentiator compared to unprotected connection.

Why Tejas?
The Tejas Advantage
Advanced OAM&P Capabilities
Strong Product Line
High-end Data capabilities
Advanced OAM & P features Network Management Point-and-click provisioning (PNCP) application tool => drastically decreases provisioning time Auto discovery of network elements as and when they are added to the network, and auto discovery of optimised network topology and path for a given end-to-end circuit => More automation leads to speed and ease of provisioning and lesser requirement of Human Capital
Advanced OAM & P features Customer Network Management (CNM) Service provider can give access to their customers to monitor and manage their leased bandwidth => Additional revenue for Service Providers Can be packaged with PNCP and LCAS to offer a service where Service Providers’ customer can upgrade bandwidth => More flexibility to the Customers
Advanced OAM & P features Use of SFPs Replace the transceivers without disconnecting the rest of the network => eliminates downtime for parts of network not directly in line of fault Separates the card from the lasers => simplifies inventory management Support for Optical Monitoring => enhances the installation, activation, and troubleshooting of these SFP optics
Advanced OAM & P features Extensive support for management connectivity in third-party networks DCC transparency options and E1 Management => Management possible even in third-party networks Open North-bound interfaces e.g. CORBA => Integration is relatively easy for Fault and Performance monitoring
Product Line Diverse Product Portfolio Full drop-capabilities in each product => no need for expansion shelves Multi-ADM (MADM) capabilities => single NE replaces multiple ADMs Multiple products for each of STM-1/4/16 and Ethernet => customized solutions for each application
Product Line Common platform Common Software base => simplifies Network Management Tributary cards => scope for future expansion and better inventory management
Data Capabilities Integrated Layer-2 functionality One of the earliest vendors globally to ship standardscompliant EoS solutions---shipping since Jan 2003 => Advanced and field-proven Ethernet over SDH (EoS) solution Allows the service provider to build a single Converged network platform => Offer new data services without losing any management or SLA capability => Service multiple customers using a single platform
Data Capabilities Support for Metro Ethernet Forum(MEF) Services Diverse Ethernet Portfolio – Transport cards for dedicated services like EPL services and Switching cards for Multi-point services like E-LAN => Cost-effective and Flexibility MEF Certification in process => Service Providers can provide MEF certified services
Advanced Data Capabilities Ethernet OAM Capabilities Ethernet in First Mile (EFM-OAM) Capabilities (802.3ah) => Health monitoring of the client Ethernet link => Troubleshooting through remote loop backs => Auto-discovery of OAM capable nodes for better management Connectivity Fault Management (CFM-OAM) Capabilities (802.1ag) => End-to-end health monitoring of the Ethernet services
Advanced Data Capabilities Resilient Packet Ring (RPR) Support RPR support through addition of a tributary card => Build a true Converged Network with RPR/Ethernet/SDH
