Cisco 3600 Series
ATM OC-3 Network Modules
Introduction
In late 1996 Cisco Systems introduced the Cisco 3600 series
family of modular, cost-effective, and high-performance dial
access routers targeted at regional and branch office and
small to medium-sized Internet Service Providers (ISPs). Over
the next two years, the Cisco 3600 series announced further
extensions to the platform with support for Fast Ethernet,
voice/fax over IP, internal digital and analog modems,
high-density asynchronous dial, ATM25/ADSL, and
High-Speed Serial Interface (HSSI), adding multifunction
capabilities to the initial dial-access solutions.
Now, with the announcement of three new versions of
ATM OC-3 network modules, the Cisco 3600 series further
expands its flexibility as a multifunctional branch office
solution for service provider and enterprise customers. These
new modules add to the broad portfolio of Cisco ATM
Customer Provided Equipment (CPE) and central office
products, that allow branch offices to take advantage of the
higher bandwidth and quality of service (QoS) available with
ATM services. High-speed ATM access on the Cisco 3600
provides cost-effective, value-added, high-speed managed
router services to both enterprise and service provider
customers.
The new ATM OC-3 network modules address the
growing demand for improved ATM QoS features, combined
with the advanced Layer 3 class of service (CoS) capabilities
provided by a router. Users now have the ability with the
Cisco 3600 series to provide robust QoS mechanisms for
prioritization of traffic from legacy and high-speed LANs
over an ATM network. These new network modules allow
the Cisco 3600 series to enter the high-speed ATM access
market by providing solutions that enable ATM broadband
services to fit into many companies communications budgets,
not just the very large corporations. Managers can now
cost-effectively terminate high-speed ATM on the Cisco
3600, providing robust QoS features for applications at the
branch-office LAN such as videoconferencing, distance
learning, video broadcast, and voice/fax over IP over ATM
applications.
The OC-3 ATM network modules developed for the
Cisco 3600 modular access routers provides a single-port
SONET and SDH-based OC-3c/STM-1 interface for
worldwide use. These modules are designed to support the
convergence of data, voice, and video services that allow
customers to migrate existing voice and video traffic onto a
corporate data network for substantial cost savings.
