Data Sheet

Cisco 3640-DC Multiservice
Access Platform for Service Provider
Network Operations Connectivity

The Cisco 3640-DC is a robust National Equipment Building Systems (NEBS) Level 3/European Telecommunication Standards Institute (ETSI)-compliant networking platform, specifically designed to optimize the network-management operations of service provider networks; DCN is also known as Data Communication Networks.

As part of the scalable Cisco DCN solution, which includes the Cisco Catalyst® 1924-DC Switch, Catalyst 2924M-XL Switch, Catalyst 4003-DC Switch, Cisco 3662-DC-CO, Cisco 2600-DC Series Multiservice Access platform, and the telco DCN feature set of Cisco IOS® Software, the Cisco 3640-DC supports central-office (CO) Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) operations management interfaces, as well as async and X.25 interfaces on the same platform. The DCN provides connectivity for network elements (NEs) in service-provider, inter-exchange carriers (IXCs), and Post, Telephone, and Telegraph (PTT) networks for alarm monitoring, remote provisioning and diagnostics, configuration backup, and software downloads. Other operations systems network applications include local number portability and billing data collection. In addition, competitive local exchange carriers (CLECs) can use the Cisco 3640-DC in their numerous points of presence (POPs) or CO colocations for digital-subscriber-line access multiplexers (DSLAMs), voice switches, and transmission operations networking. (See Figure 1.)


Figure 1: Cisco 3640-DC


The Cisco 3640-DC is a versatile multiservice access platform designed for medium-density CO configurations, significantly reducing the complexity and costs of managing DCN operations. By integrating multiple NEs onto one DCN infrastructure, the Cisco 3640-DC allows service providers to streamline their operations. The Cisco 3640-DC provides flexible connectivity to legacy X.25 and async devices as well as Ethernet devices, facilitating a graceful migration from proprietary- to standards-based network elements.

The Cisco 3640-DC is two rack units (RUs) high and less than 16 inches deep. It can also be ordered for AC environments with either an AC power supply option, or a redundant AC power supply module for high availability. Rear access cabling allows easy connectivity, and a modular design allows fast servicing of field-replaceable units (FRUs). Common language equipment identification (CLEI) coding is provided for easy identification and tracking of CO equipment. Robust network-management capability for the Cisco DCN solution is achieved using the CiscoWorks, CiscoView, and CiscoView Stack Management Interface applications. These same applications are used to manage a large number of Cisco products that have already been deployed in existing networks, presenting network support personnel a familiar look and feel. The Cisco 3640-DC is equipped with four modular expansion slots. Currently there are more then 70 different modular interfaces that can be used in these slots, providing unmatched versatility. For example, service providers can populate three of the four slots with 32-port asynchronous modules and achieve a density of up to 96 async ports in a compact form factor.

  • A modular architecture offers a huge selection of LAN and WAN interfaces and provides easy customization for individual needs and the flexibility for network modules to be added on a "pay-as-you-grow" basis.

  • The Cisco 3640-DC is a key component of Cisco's DCN solution.

  • The Cisco 3640-DC consolidates high density of low-speed serial links and high densities of IP ports at a cost-effective price point. For example, 24 synchronous ports or 96 asynchronous ports can be supported on the platform.

  • All parts are field-upgradable, allowing quick, easy, and low-cost maintenance.

  • An analog phone can be connected to the Cisco 3640-DC using the voice network module, allowing ease of communication between a service technician and the operations center. This provides great savings by eliminating the need to run a phone line to the rack, and for controlled equipment vaults where recurring phone line charges can add up.

  • WAN interface cards and network modules are shared with the Cisco 2600-DC and the Cisco 3662-DC-CO Series Multiservice Access platforms, allowing reduced cost of maintaining inventory of modular components and requiring lower training costs for support personnel.

Easy-to-open chassis design allows fast and easy access for installation or upgrading of a variety of system components (field-replaceable component design).

The NEBS Level 3/ETSI platform is two RUs high, and can fit right into 19- or 23-inch-wide relay racks alongside other CO equipment.

Summary

As New World computing capabilities change the landscape of the CO operations network, support for a variety of network interfaces and greater requirements for bandwidth are straining current DCN capabilities. The Cisco 3640-DC system provides a very good medium-sized platform for the Cisco DCN solution, by enabling telco service providers to consolidate both legacy as well as standards-based network-management traffic over a single infrastructure for connectivity to their operational support systems. The Cisco 3640-DC enables a service provider to deploy an ultra-reliable, scalable, and versatile platform, which allows graceful migration from current proprietary-based to New World, standards-based infrastructure in an extremely cost-effective manner.

Adding the capabilities of Cisco IOS Software, which runs most of the Internet traffic around the world today, Cisco not only provides a full-featured DCN solution, but also enables a variety of additional features on the Cisco 3640-DC. Features such as virtual private networks (VPNs) and voice can enhance a telco operations network. These capabilities make the Cisco DCN solution the industry's best, with greater robustness and feature richness than any other solution available in the marketplace. Customers who want to take advantage of these additional capabilities along with the DCN features should purchase an Enterprise Plus feature set.

Cisco support solutions are designed for one purpose—to put customers quickly in touch with appropriate resources. The Cisco support network consists of Technical Assistance Center (TAC) engineers, development engineers, field engineers, parts warehouses, delivery services, and service partners. By including Cisco support with Cisco equipment purchases, customers immediately gain access to a wealth of support resources.

Technical Specifications

Table 2 provides technical specifications for the Cisco 3640-DC.

Alarm Interface Controller Network Module

The alarm interface controller (AIC) is a network module that greatly expands the network monitoring and control capabilities of the Cisco 2600 and 3600 Series routers. The AIC functions as an integrated entity residing within the Cisco 2600 Router to provide network alarm monitoring and remote control of network elements. The AIC reduces service-provider and enterprise operating expenses by facilitating a single "box solution," eliminating the need for a dedicated external alarm-monitoring device. This greatly simplifies network layout, monitoring, and control, resulting in lower operations, administration, maintenance, and provisioning (OAM&P) costs. The AIC is supported in Cisco IOS 12.2 (2) XG and 12.2(7)T. The AIC network module supports 64 discrete alarm inputs, of which 8 of the last 64 alarm points are software-configurable to accept either analog or discrete inputs. The AIC further supports 16 control relays to facilitate the remote control of network elements.
