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 15310-CL, Cisco ONS 15454, and Cisco ONS 15600, the Cisco ONS 15310-MA provides an end-to-end solution for multiservice transport over SONET 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 1.5-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 15310-CL, 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 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 (two systems fit side by side in six rack units [RUs]), the Cisco ONS 15310-MA provides six slots for hot-swappable traffic interfaces. High-density electrical (up to 168 DS-1), Ethernet (up to 32 10/100Mps, upto 24 1000 Mbps), 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 STS and 5-Gbps VT1.5-TDM cross-connect can switch SONET 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. Unidirectional-path switched ring (UPSR) and 1+1 automatic protection switching (APS) can be configured for greater fault tolerance in the optical network. The Cisco ONS 15310-MA is NEBS Level 3, FCC, and UL 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.
Telcordia's Trunk Information Record Keeping System (TIRKS), Network Monitoring and Assurance (NMA), and Transport Element Activation Manager (TEMS) fully support the Cisco ONS 15310-MA. Management support from these embedded operations support systems (OSSs) helps incumbent service providers to easily integrate the Cisco ONS 15310-MA into their network infrastructure - whether extending existing networks or deploying new ones.
Applications
The flexibility of the Cisco ONS 15310-MA gives it superior versatility. Its true multilayer Ethernet-over-SONET 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 15310-CL, 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 OC-3 or OC-12 collector rings. For example, multiple Cisco ONS 15310-CL 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 video conferencing 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).

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 15310-CL 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
A similar application takes place in high-rise buildings where the Cisco ONS 15310-MA can serve as a hub to distribute traffic through an optical backbone to Cisco ONS 15310-CL or other Cisco ONS 15310-MA devices in different floors (Figure 5).

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-SONET 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 SONET 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-CL or Cisco ONS 15310-MA for Layer 1 Ethernet-over-SONET applications. The Cisco ONS 15310 CE-Series 6-Port 10/100/1000 SFP-based Carrier Ethernet Card provides a hardened Ethernet solution and can be installed in a Cisco ONS 15310-MA for Layer 1 Ethernet-over-SONET applications The Cisco ONS 15310 CE-Series provides port-mapped services and interoperability with the Carrier Ethernet cards supported on the Cisco ONS 15454, delivering Ethernet and Fast Ethernet solutions that span access and metropolitan-area networks.
Multilayer Ethernet-over-SONET Transport
Traditional Ethernet-over-SONET services consist of simple Layer 1 mapping of Ethernet frames into SONET for transport between two endpoints where SONET 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-SONET 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 in the Cisco ONS 15310-CL or 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.
