As existing and emerging technologies converge, successful Providers will be those who can quickly roll out capacity and new service offerings over their existing transmission network. Providers with extensive transmission infrastructure face the challenge of deploying and integrating diverse services onto an already heavily utilised network. Furthermore, market pressures mean these service must be deployed quickly and economically. Modern transmission networks demand a reliable, flexible Operational Support System (OSS) that can unify multi-technology infrastructure and:
The S2Net network management suite is ideal for managing transmission networks, supporting the broad range of voice and data technologies that make up a Provider’s backbone – Cable, DWDM, HFC, PDH, SDH, SONET and others. S2Net includes a sophisticated OSS for service configuration, resource provisioning and inventory management, providing tools to:
S2Net provides integrated, flow-through provisioning, is easily configurable and can be integrated with other inventory, workflow and activation systems. A complete network management solution, it supports a wide range of technology and service layers, such as: ATM, DSL, Ethernet, Frame Relay, SDH & SONET, DWDM, PDH and IP.
100% Consistent Data View – a unified, multi-vendor, time-spanning database means S2Net improves design confidence and reduces errors, ensuring capacity and service rollouts are delivered on time while minimising rework costs.
Sophisticated Validation – avoid errors with technology-aware and process-aware validation. All S2Net tools are driven by configurable rules to ensure your transmission network is consistent and correct throughout the lifecycle of all components.
Standards-based Data – the database model is based on accepted ITU-T and ETSI standards to meet the needs of today and tomorrow, supporting all equipment regardless of vendor.
Automated Business Processes – S2Net streamlines service and infrastructure provisioning through powerful rules-based automation. This flow-through provisioning speeds labour-intensive tasks, such as terminating cable fibres.
Open Integration – S2Net uses standard interfaces to connect with other systems, so does not lock you into a proprietary solution or prevent you from using products from other vendors. Build on your existing OSS investment.
Extensibility – extend the S2Net business, technology and engineering rules in-house to deploy new generations of transmission infrastructure and utilising services quickly.
Maximise Network Utilisation – clever design algorithms locate and utilise idle infrastructure to maximise network utilisation.
Maximise Reliability – S2Net brings protection and Effect-of-Failure reports so you can design critical, failure-resistant services and infrastructure.
Vendor-independence – S2Net supports equipment from leading suppliers, such as Alcatel Lucent, Sony Ericsson, Nortel, Siemens Nokia, Fujitsu, NEC, Cisco and Marconi.
Dense Wavelength Division Multiplexing (DWDM)
| Simple Services | Complex Services |
|---|---|
