Cisco 3660 Multiservice Platform for Large Branch-Office Multiservice Networking
The Cisco 3660 leverages the multiservice architecture of the Cisco 2600 and 3600 series platforms, extending those capabilities for use in larger branch-office applications or for telco-managed services as customer premise equipment (CPE). The Cisco 3660 has the versatility to support today's branch and enterprise requirements for data, voice, video, and hybrid dial access applications, and the high-speed connectivity necessary to support the increased bandwidth needs for multiservice applications.
The uniquely modular chassis of the Cisco 3660 is designed with high availability and field service simplicity in mind, making it a robust yet highly cost-effective element in the network over which to deploy mission-critical applications. The Cisco 3660 provides unprecedented versatility with a broad range of available network modules and extensive flexibility with a variety of configurable options for customer-specific applications. The Cisco 3660 uses the same network modules that are available today on the Cisco 1600, 1700, 2600, and 3600 multiservice platforms, protecting customer investment, streamlining operations costs associated with sparing of parts, and for training.
Distinguishing features of the Cisco 3660 include integrated power redundancy and module hot-swap capabilities, which provide higher product availability for mission-critical applications. The integrated ports on the motherboard of the Cisco 3660 free up all six network module slots to enable higher densities of LAN/WAN or multiservice aggregation. The additional slots of the Cisco 3660 combined with the expanding capabilities of enhanced network modules enable new business applications, such as higher densities of packetized voice aggregation and branch-office Asynchronous Transfer Mode (ATM) access ranging from T1/E1 Inverse Multiplexing for ATM (IMA) to OC-3 speeds.
The Cisco 3660 can be ordered in several configurations. The base system consists of:
- Six expansion slots for network module support
- Two advanced integration module (AIM) slots for hardware acceleration and increased processing power
- Chassis support for redundant AC or DC power supplies
- One AUX port
- One console port
- Two personal computer memory card international association (PCMCIA) card slots for software and configuration backup

The Cisco 3660 can be ordered with either one or two Fast Ethernet ports and provides hot-swap capability of like-to-like network modules and for redundant power supplies, ensuring high availability. Rear-access cabling allows easy connectivity, and a modular design allows easier servicing of field-replaceable units (FRUs).
Robust network management capability for the Cisco 3660 is achieved using the CiscoWorks, CiscoView, and CiscoView Stack Management Interface applications. The 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.
One of the key benefits of the Cisco 3660 is that it runs Cisco IOS® software, the operating system deployed in most of the Internet backbone equipment around the world. The feature richness of Cisco IOS software becomes immediately available to customers who deploy the Cisco 3660, allowing them to enable a variety of applications to fulfill their growing business needs.
Key Features and Benefits
The key features and benefits of the Cisco 3660 include:
- Density and performance—The Cisco 3660 multiservice platform with integrated ports, and six expansion slots, enables new business applications such as higher densities of packetized voice aggregation and branch-office ATM access ranging from T1/E1 IMA to OC-3.

- Data, voice, video, and hybrid dial access integration—The Cisco 3660 allows customers to support the widest breadth of applications on a single platform, including data, voice, video, and hybrid dial access integration. Aggregation of applications on a single platform significantly streamlines operations and networking costs by simplifying support and manageability of branch-office networking requirements. Today there are more than 60 different network modules that can be used in these slots, providing unmatched versatility.
- Investment protection—The Cisco 3660 shares modular interfaces with the Cisco 1600, 1700, 2600, and 3600 series platforms, simplifying network support requirements, enabling economies of scale, minimizing training costs, and providing customer-specific options to fulfill today's and tomorrow's small, medium-sized, and large branch- office needs. Furthermore, the ability of the Cisco 3660 to support field-upgradable modular components enables customers to easily change network interfaces or other components without a "forklift upgrade" of the entire remote branch-office solution.
- Lower cost of ownership—Integrating the functions of built-in data service unit/channel service unit (CSU/DSUs), ISDN network termination (NTI) devices, and other equipment found in branch-office wiring closets provides a space-saving, cost-effective solution that can be managed remotely using network management applications such as CiscoWorks and CiscoView.
Additional Features and Benefits:
Versatility
- Modular architecture that 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.
- A variety of interfaces with feeds and speeds ranging from 300-bps async up to ATM OC-3 provide connectivity to IP, ATM, Frame, and TDM networks and will support the needs of any large enterprise branch-office environment. A full description of these interfaces is provided in Table 2.
- Facilitates the consolidation of high-density digital voice interfaces with additional functionality, providing a very cost-effective solution. For example, a typical branch office could use the Cisco 3660 to consolidate the following:
- WAN interface cards and network modules are shared with the Cisco 1600, 1700, 2600, and 3600 series multiservice platforms, reducing the cost of maintaining inventory of modular components and lowering training costs for support personnel.
- All parts are field upgradable, allowing quick, easy, and low-cost maintenance.
Performance
- A high-performance RISC architecture provides up to 120 Kpps of fast switching capability or up to 12 Kpps of process switching capabilities.
