G-Series Gigabit Ethernet Card (G1K-4)
for Cisco ONS 15454 SONET/SDH MSPP
The G-Series Gigabit Ethernet card for the ONS 15454 platform enables the delivery of carrier-class, private line Ethernet services. The ONS 15454 enables service providers and enterprise customers to seamlessly migrate their networks, from offering/transporting TDM services, or Ethernet/ATM over TDM, to Ethernet services over a single network, eliminating the operation of multiple overlay networks to support currently deployed services. Gigabit Ethernet Networking Flexibility in the Optical Metro Network.

The Cisco ONS 15454 is the industry's leading metro optical transport platform, with over 1000 customers and 30,000 systems deployed worldwide. The ONS 15454 combines supercharged SONET/SDH transport, integrated optical networking including ITU Grid Wavelengths and DWDM, unprecedented multiservice interfaces on demand including Ethernet and TDM to deliver radical economic benefits to service providers. The ONS 15454 provides the functions of multiple network elements in a single platform. As part of Cisco's unrivaled IP+Optical product line, the ONS 15454 combines the capacity of optical transport with the intelligence of IP to cost-effectively deliver next generation voice and data services.
Cisco's metro optical transport leadership also extends to Ethernet service capability. The ONS 15454 began offering Ethernet service capabilities in early 1999. Service providers want to provide Ethernet to their customers due to its lower cost, ubiquitous service, and bandwidth scalability. A key differentior for service providers is their ability to offer TDM, Ethernet, and IP based services to their customers.
With the introduction of a new four-port Gigabit Ethernet (GigE) card, model G1K-4, for the ONS 15454 Optical Transport Platform, service providers can now deliver Gigabit media flexibility without building an overlay network or redesigning their existing SONET infrastructure. The unprecedented TDM capabilities of the ONS 15454, combined with high density DWDM optics and the evolutionary four-port GigE card, enables service providers to deliver on the key market differentiators needed to ensure their success.
Product Overview
The Cisco ONS 15454 G-Series Gigabit Ethernet card is a four-port, 1000 Mbps Ethernet module using pluggable Gigabit Ethernet interface converter (GBIC) optical modules for the flexible interface support to multiple types of client equipment. The G-Series card has four "virtual" SONET/SDH interfaces that can be mapped to optical transport cards via the cross-connect cards within the ONS 15454 chassis. These virtual ports are scalable in size from STS-1 (~50 Mbps) to STS-24c/VC-4-8c (~1.25 Gbps), or an aggregate of 2.5 Gbps total virtual port bandwidth per card.
There are two operating modes for the G-Series card, cross-connected and transponder. In cross-connected mode, the Gigabit Ethernet client interfaces each get encapsulated into a SONET/SDH payload and exits the G-Series card through the virtual ports for cross-connection to the optical interfaces, outlined in Figure 2.
Figure 2
G-Series Cross-Connected Operating Mode

The G-Series payloads can be transported over protected circuits (UPSR, path protected mesh network (PPMN), BLSR, and 1+1) or unprotected circuits, providing the level of resiliency specified by the network administrator or available bandwidth.
In transponder operating mode, the Gigabit Ethernet client interfaces each get directed, within the G-Series card, to another Gigabit Ethernet client interface on the same G-series card, never accessing the SONET/SDH encapsulation process or the virtual ports, as detailed in Figure 3.

G-Series Transponder Operating Mode

This enables a wideband optical signal from a switch/router/server to be converted to a CWDM or a DWDM wavelength to deliver a scalable transport solution for Gigabit Ethernet based services (see Figure 4).

G-Series Transponder Application

The transponder mode will support both bidirectional and unidirectional Gigabit Ethernet signals, enabling servicing of different application types (Figures 5).

Applications
The Cisco ONS 15454 G-Series product provides the flexibility to meet the demands of a wide variety of network applications found within many customer networks. The following diagrams outline a few of the applications that can be met using the G-Series cards.
Reliable Enterprise Networking
The ONS 15454 equipped with the G-series card allows the enterprise user to build a highly reliable, multiservice network to support their video, voice, and data network (see Figure 6). Additionally, the ONS 15454 based network provides the flexibility to support traditional TDM based services along with Ethernet services, enabling a evolutionary network growth versus a revolutionary, risky implementation. The ONS 15454 provides transport scalability from 155 Mbps (OC-3/STM-1) up to 320 Gbps (32 wavelength of 10 Gbps), positioning the enterprise network for future growth.

Reliable Enterprise Networking

Service providers can also leverage CWDM and DWDM GBICs in the G-Series card to allow for a scalable access network, as shown in Figure 7.

Private Line Gigabit Ethernet
Metropolitan networks deliver services to end user customers. As such, a metropolitan network that supports a wide range of service capabilities will allow the service provider to offer a tariff mix to meet the customer's needs. The Cisco ONS 15454 provides the foundation for building an advanced multiservice network over an extremely reliable SONET/SDH infrastructure (see Figure 8). The G-Series Gigabit Ethernet card enables the delivery of data services, such as transparent LAN services (TLS) or Internet access, over a carrier-class optical infrastructure supporting traditional TDM services. The G-Series solution enables the service provider to offer a wide variety of Ethernet service-level agreements (SLA), using the scalable transport capability and network protection via SONET path protection, BLSR, Linear 1+1, or unprotected transport capabilities offered by the platform. It is also very important for the network to be manageable and usable by the service provider's technicians. The provisioning of an Ethernet circuit over a G-Series equipped network is easy by leveraging the ONS 15454's embedded A-Z circuit provisioning wizard for network level circuit creation. The G-Series card also supports TL-1 based provisioning to simplify integration with many embedded service provider management systems.

Cable Television Data Transport
Cable television operators are experiencing rapid growth of subscribers to their data services. According to the National Cable Television association (NCTA), data cable subscriptions grew 337 percent from January 2000 to January 2002. The Cisco ONS 15454 with G-Series module provides a solution to transport the growing data requirements of the cable television networks. The Cisco solution will enable the cable operator to distribute the data traffic, using the G-Series modules, from the master headend to the multiple secondary headends (SHE) using a fully protected SONET/SDH/DWDM transport network (see Figure 9). The ONS 15454 platform supports in-service bandwidth upgrades, and is scalable from 155 Mbps to 10 Gbps and supports DWDM, so meeting data growth demands is easily met.

The above are just a few of the applications that can be cost-effectively deployed leveraging the ONS 15454 with the G-Series modules.

Managing the Optical Transport Platforms
Provisioning and managing an optical transport device with CTM's Java-based graphical user interface (GUI) is easier than ever. CTM is the carrier-class element management system (EMS) for the Cisco ONS 15000 series product line. CTM provides advanced capabilities in the functional management areas of configuration, faults, performance, and security for Cisco optical network elements, subnetworks, and networks. CTM is based on a client/server architecture that scales to support up to 1000 network elements and 100 simultaneous clients. CTM is a key enabler for automation of the OSS through the northbound interfaces to a network management system (NMS) or operations support system (OSS).
