The Cisco® ONS 15310-MA is a Multiservice Provisioning Platform (MSPP) that switches packet and TDM traffic, and interfaces to both circuit-based and Ethernet/MPLS backbone networks. Together with the Cisco ONS 15305, Cisco ONS 15454, and Cisco ONS 15600, the Cisco ONS 15310-MA provides an end-to-end solution for multiservice transport over SDH networks.

Product Overview

The Cisco ONS 15310-MA (Figure 1) is a carrier-class MSPP that efficiently switches Ethernet and TDM traffic for use in metropolitan and regional optical networks. Its flexibility and scalability allow it to support 2-Mbps to 2.5-Gbps TDM, as well as 10/100/1000-Mbps Ethernet interfaces. The Cisco ONS 15310-MA can aggregate traffic at a central office or collect services at the customer premises. At a central office, it can groom traffic from multiple customer-located network elements, such as the Cisco ONS 15305, Cisco Catalyst ® 3750 Series Switch, or another Cisco ONS 15310-MA for distribution to other networks or handoff to specialized networking devices, such as a ONS 15454 SDH, ONS 15454 MSPP-on-a-blade, ONS 15600 SDH, Cisco 7600 Series Router, a high-capacity digital cross-connect (DXC), or a Class 5 telephone switch. At the customer premises, the Cisco ONS 15310-MA can collect high-density and high-capacity traffic from medium-sized and large businesses, or from several customers in a multitenant location.

Carrier-Class Compact MSPP

In a very compact chassis (six rack units [RUs]), the Cisco ONS 15310-MA provides six slots for hot-swappable traffic interfaces. High-density electrical (up to 126 E1), Ethernet (up to 32 10/100BASE-T and up to 24 GE), or optical interfaces can be terminated in this small footprint to optimize use of expensive real estate at the central office or remote terminal cabinet. A centralized two-stage 20-Gbps AU-4 and 5-Gbps TU12-TDM cross-connect can switch SDH encapsulated traffic from any tributary port onto any optical interface.
All Cisco ONS 15310-MA common equipment, including processor, cross-connect, timing, and power supply, can be optionally duplicated for 99.999% reliability. Protection for TDM electrical as well as optical interfaces is also possible. Subnewtork Connection Protection (SNCP) and Multiplex Section Protection 1+1 (MSP) can be configured for greater fault tolerance in the optical network. The Cisco ONS 15310-MA is CE compliant, and supports industrial temperature ranges, making it fully qualified for deployment in central offices, customer locations, or remote terminals.

Management

Each Cisco ONS 15310-MA is equipped with Cisco Transport Controller, a subnetwork craft interface tool that simplifies node control. The Cisco Transport Controller graphical user interface (GUI) allows easy node turn-up, autorouted A-to-Z circuit provisioning, and rapid service creation. Cisco Transport Controller provides:

• Element-level control

• Quick access to operations, administration, maintenance, and provisioning (OAM&P) functions

• Transaction Language One (TL1) command window

• Graphical representation of network topology, network conditions, and shelf configurations

Cisco Transport Manager is the comprehensive element management system for the entire Cisco ONS product line. Integrating fault, configuration, and performance management, Cisco Transport Manager simplifies and strengthens optical network OAM&P. The client-and-server platform easily scales to manage up to 1000 network elements and 100 simultaneous users. Cisco Transport Manager helps service providers quickly identify and correct network problem areas and more rapidly deploy revenue-generating services.
Both the Cisco Transport Controller and Cisco Transport Manager support the entire Cisco ONS Family. This allows a single craft tool, as well as element manager interface, for fault management, configuration, and provisioning across the network. The end-to-end management capabilities of Cisco Transport Controller and Cisco Transport Manager increase profitability for service providers by reducing operational expenses and minimizing service activation time.

Applications

The flexibility of the Cisco ONS 15310-MA gives it superior versatility. Its true multilayer Ethernet-over-SDH transport capabilities allow service providers to more efficiently add support for next-generation, packet-based services to their existing infrastructure while limiting capital and operational expenditures and increasing speed of service delivery. Interoperability with the Cisco ONS 15305, Cisco ONS 15454, and Cisco ONS 15600 provides a robust network solution that can deliver economical, scaleable, and cost-effective services on demand. The versatility and reliability of the Cisco ONS 15310-MA make it the optimal choice for a wide variety of applications, some of which are listed in the following sections.

Metro Access Aggregation

The Cisco ONS 15310-MA can serve as the first point of aggregation for customer access equipment that delivers services directly to the customer site. Flexible Small Form-Factor Pluggable (SFP)-based optical interface modules can terminate STM1, STM4 and STM16 collector rings. For example, multiple Cisco ONS 15305 platforms can be aggregated on a Cisco ONS 15310-MA at an end-office or small central office (Figure 2). Customer traffic can then be groomed for transport over an optical uplink, or terminated onto colocated networking devices - such as a Cisco 7600 Series Router or a Class-5 switch - using tributary interface ports.

Figure 2. The Cisco ONS 15310-MA as a Multiservice Aggregation Device

Wireless Aggregation

With the advent of third-generation (3G) mobile services, wireless networks require high-capacity infrastructure to transport bandwidth-intensive services such as Web browsing or videoconferencing from a cellular phone. The multiservice capabilities of the Cisco ONS 15310-MA, together with its carrier-class reliability, compact size, and reduced power consumption, make it ideal for backhaul of TDM and packet traffic from the cell site to the nearest point of presence (POP) (Figure 3).

Figure 3. The Cisco ONS 15310-MA in a Cellular Network Transport Infrastructure

Customer Access Platform

Service providers can collect voice and data services using the Cisco ONS 15310-MA at the customer location. Its carrier-class features, such as redundant common equipment and facility protection, allow it to support 99.999% availability requirements, making it specifically valuable for supporting the most demanding service-level agreements (SLA). Its compact form factor makes it easy to deploy in enterprise customer communication closets, which are typically space-constrained.

Enterprise Networks and Managed Services

The Cisco ONS Family of products can also serve as an optical transport platform for an enterprise-owned network or a managed service. A Cisco ONS 15310-MA located at the headquarters or main building of an office, university, or government campus, for example, can aggregate Ethernet and TDM traffic from multiple remote sites. Other Cisco ONS 15310-MA or Cisco ONS 15305 units can be used in these remote locations to connect to private branch exchange (PBX) systems and LANs. The hub unit would simultaneously interface with the service provider to receive bandwidth for switched voice or data services, Internet access, or a wide-area extension of the VPN (Figure 4).

Figure 4. Cisco ONS 15310-MA in a Campus or Metropolitan Corporate Network

Another application is the use of the 15310MA as Low Order aggregation device for the MSPP on a blade card. When the DWDM ring has to bring E1, E3, DS3 and FE there is no economic way to transport low bit rate signals. Aggregating them over standard SDH transport may cost a in terms of common part. Leveraging on ONS 15454 MSTP MSPP on a Blade, that aggregate TDM over wavelength and the 15310 MA which provide very cost effective low order aggregation (Figure 5).

Key Features and Benefits

The Cisco ONS 15310-MA provides a wide array of important features and benefits that make it the preferred choice for service providers and enterprise customers looking to:

• Reduce capital and operational expenditures

• Deploy a network infrastructure that supports revenue-enhancing services

• Offer the highest service availability to a demanding customer base

The following sections describe some of the unique features and benefits of the Cisco ONS 15310-MA.

Small Footprint

At only 6-RU high, the Cisco ONS 15310-MA provides unprecedented service density in its compact form factor (Figure 6). The small footprint increases network design flexibility, allowing service providers to deploy a powerful MSPP in small cabinets where space is limited, and deliver higher-bandwidth services in remote locations. It also helps service providers conserve space in central offices. Finally, as a customer access platform, the Cisco ONS 15310-MA can be more easily deployed in telecommunications closets of enterprise customers, resulting in more cost-effective and faster service activation.

Figure 6. The Small Form Factor Allows for Flexible Rack-Mounting Options

Carrier Ethernet-over-SDH Transport

The Cisco ONS 15310-MA can be equipped with Ethernet cards to facilitate the delivery of carrier-class, private-line Ethernet and Fast Ethernet services. Virtual Concatenation (VCAT), Link Capacity Adjustment Scheme (LCAS), standard encapsulation, and SDH sub-50-millisecond (ms) resiliency schemes are used to deliver these point-to-point data services efficiently and in conjunction with the traditional TDM service-delivery requirements.
The Cisco ONS 15310 CE-Series 8-Port 10/100 Carrier Ethernet Card can be installed in a Cisco ONS 15310-MA for Layer 1 Ethernet-over-SDH applications. The Cisco ONS 15310 CE-Series provides port-mapped services and interoperability with the Carrier Ethernet cards supported on the Cisco ONS 15454 and E100-8-W cards of the 15305, delivering Ethernet and Fast Ethernet solutions that span access and metropolitan-area networks.
The Cisco ONS15310 CE-MR-6 port, 10/100/1000 Carrier Ethernet card enable up to 24 GE ports on the 15310 MA per chassis. Fully interoperable with Carrier Ethernet cards of the ONS 15454 and GE-2-W cards of the 15305, as well as GE services on the ASAP card of the 15600, the CE-MR-6 card delivers Gigabit Ethernet services over Metropolitan area networks, DWDM Aggregation, EPL.

Multilayer Ethernet-over-SDH Transport

Traditional Ethernet-over-SDH services consist of simple Layer 1 mapping of Ethernet frames into SDH for transport between two endpoints where SDH protection mechanisms are used to deliver sub-50-ms resiliencies. Consequently, bandwidth must be reserved for both working and protected traffic, resulting in underutilization of available bandwidth. Furthermore, services such as voice over IP (VoIP), digital videoconferencing, surveillance, and VPNs all require interconnectivity between multiple end locations. Using the traditional Ethernet-over-SDH point-to-point model, these solutions become very complicated and highly inefficient.
Switched Ethernet uses statistical multiplexing, which supports oversubscription and better usage of Ethernet networks. Resilient Packet Ring (RPR) enables efficient multipoint services, with spatial reuse of bandwidth and sub-50-ms, Layer 2 ring-based protection. Using switched Ethernet and RPR results in a more robust, efficient solution that economically addresses the needs of today's advanced services requirements.
The Cisco ONS 15310 ML-Series 8-Port 10/100 Ethernet Card is a Layer 2-switched services card that can be installed Cisco ONS 15310-MA. The card interoperates with the Cisco ONS 15454 ML-Series data cards on the Cisco ONS 15454, delivering Ethernet and Fast Ethernet solutions that span access and metropolitan-area networks.

Integrated Network Management

The Cisco Transport Controller and Cisco Transport Manager support the end-to-end Cisco ONS family of products. With the Cisco optical integrated network management solution, network professionals only need to learn how to operate a single, easy-to-use graphical interface, and they are capable of provisioning, configuring, and troubleshooting their entire network. This helps service providers significantly reduce operational expenditures associated with training, installation and configuration of network equipment, and response to network failures. Furthermore, revenue-generating services can be provisioned more quickly with this simplified and highly integrated network management solution, making an immediate impact to the service provider's top line.

SFP Optics

All optical interfaces on the Cisco ONS 15310-MA support SFP optics for greater transmission reach, line rate, and wavelength flexibility. This simplifies system design, as well as reduces sparing costs for service providers.
