The Cisco 6400 Service Connection Manager provides simplified ATM and Layer 2 and 3 IP services to access servers and Digital Subscriber Line Access Multiplexers (DSLAMs) through network and service management of the Cisco 6400 universal access concentrator.
The next-generation Internet access environment combines multiple forms of narrowband and broadband access with common core services and provisioning. Rapid deployment of these complex access networks to serve millions of subscribers is known as telephony-scale data networking (TSDN). The Cisco 6400 is the first of a new generation of products addressing the need for service aggregation in TSDN deployments, and Cisco 6400 Service Connection Manager provides the integrated management capabilities through a simplified service-oriented user interface.
The network solution in Figure 1 depicts a Cisco 6400-based deployment providing high-speed IP connectivity to an end customer, and the Cisco carrier-class management system overlaying the physical network provides a simplified integrated solution while accommodating existing and new operational requirements.
An end-to-end, service-oriented xDSL deployment consists of DSLAMs and remote xDSL modems, as well as a number of other internetworking components and servers that come together to provide a seamless service offering. The Cisco 6400 universal access concentrator plays an integral part in the network architecture, located within the service provider's infrastructure and acting as a central point of control for Layer 2 and Layer 3 services. These services may include Asychronous Transfer Mode (ATM) Virtual Circuit Connections (VCCs), Point-to-Point Protocol (PPP) tunneling via Layer 2 Tunneling Protocol (L2TP) or PPP termination into local routing and to local or cached content.
Cisco 6400 Service Connection Manager assists the user in making the network connections while eliminating the need for the user to have SNMP and Cisco IOS® technical knowledge of the commands required to establish these connections. It also streamlines the provisioning process for the Cisco 6400 and provides complete element management. Cisco 6400 Service Connection Manager provides a service-oriented management view of the Cisco 6400 inbound and outbound connections.
Figure 1 Typical Service Connection Manager Environment
- Manually preprovision Cisco 6400s in the management system before actual installation and advise the system to automatically detect its presence and begin management upon physical installation and configuration
- Utilize the auto-discovery feature to identify new Cisco 6400s and their detailed hardware configurations upon physical installation
- Utilize maps that have been automatically constructed by the management system to show the exact representation of the Cisco 6400 components
- Configure the Cisco 6400 using service-oriented terms such as "subscribers," eliminating the need to understand the underlying network fabric
- Create and manage subscribers rather than Cisco 6400 ports and PVCs
- Provision connections through the Cisco 6400, via a service/subscriber-oriented user-interface, without the technical knowledge of the numerous sequences of Cisco IOS commands and SNMP Management Information Base (MIB) variables that underlie the configuration of each connection
- Define Cisco 6400-based service offering templates such as PPP-L2TP and assign one to each subscriber
- Define Cisco 6400 quality-of-service (QoS) templates and assign them to subscriber connections
- View SNMP traps, generated by the Cisco 6400, as color-coded icons on network maps
- Access the fault, configuration, accounting, performance, security (FCAPS) functionality, supported by the device via SNMP, through user-friendly GUIs that can be operated by non-SNMP experts
- Perform "mass" concurrent operations to any number of Cisco 6400 components (Node Switch Processors [NSPs], Node Route Processors [NRPs], and Node Line Cards [NLCs]), simplifying management of a large deployment of multiple Cisco 6400s
- Access to Cisco MIBs and element management functionality provided with the Cisco 6400 (such as the DSL provisioning MIB) via simple tabbed dialog boxes within the Cisco 6400 Service Connection Manager application
- Analyze historical information provided via the user-friendly event browser or performance manager
- Requires minimal user knowledge of the underlying Cisco IOS system and SNMP commands
- Provides simple, quick, and flexible installation alternatives, including preprovisioning GUI wizard and auto-discovery
- Supports configuration of QoS and service definitions in accordance with service provider policies and products
- Reduces the opportunity for error in establishing service parameters through the use of templates
- Minimizes setup time and cost for each Cisco 6400
- Minimizes connection installation time providing rapid service availability to new subscribers
- Minimizes downtime via assurance tools for fault determination and pro-active troubleshooting
- Provides the capability to achieve TSDN deployments
Typically, a service provider will offer a range of products and services that may involve setup and configuration of the Cisco 6400. For example, the service provider may define a number of QoS levels appropriate to each service. Cisco 6400 Service Connection Manager easily supports this by enabling the operator to define one or more QoS templates, according to service provider products, services and policies, that can later be applied to subscriber connections. Detailed configuration of each Cisco 6400 service supported can also be defined via predefined templates and simple GUIs, as shown in Figure 2.
Similarly, the process of connecting subscribers to services is simple with the Cisco 6400 Service Connection Manager. The complex configuration occurs "behind the scenes" and results in an end-to-end service for the subscriber, deployed on the Cisco 6400 of choice, as shown in Figure 3.

In the delivery of products and services each customer's requirements are unique. To complement the services associated with the supply and support of the Cisco 6400 Service Connection Manager, Cisco offers professional services to address the complete design and implementation of large, and often complex, network management integration projects.
Cisco 6400 Service Connection Manager can be deployed on a range of hardware platforms, from the low-cost Sun Ultra 5 workstation for small deployments to the Sun Enterprise 450 operating as large-scale multiprocessor servers with fault-tolerant hardware.
