Cisco Introduces First Internetworking Routers With Built-In DSU CSU Telecommunications Functionality.

SAN JOSE, Calif.--(BUSINESS WIRE)--March 4, 1996--Cisco Systems, Inc. today introduced the Cisco 2524 and the 2525, the first single-product routing solutions to offer completely integrated telecommunications and routing functionality.

The Cisco 2524 and 2525 eliminate the need for separate internetworking components by combining a data service unit/channel service unit (DSU/CSU) and a Basic Rate Interface (BRI) Integrated Services Digital Network (ISDN) interface with a remote office router. The DSU/CSU modules were developed with wide-area network (WAN) access providers Adtran, a leader in 56/64 kbps DSU/CSU technology, and Digital Link, Corp., a leader in FT1 DSU/CSU technology. (Note to editors: A DSU is a device used in digital transmission for connecting data terminal equipment to a digital transmission service. A CSU is a digital interface device that connects end-user equipment to the local digital telephone loop.)

The Cisco 2524 and 2525 are modular routers targeted for corporate customers who want to deploy a single, remotely managed intelligent device to their remote offices for both WAN and telecommunications line connectivity. These routers are also an ideal solution for Internet Service Providers (ISPs) who offer turnkey ISP-managed Internet connections.

Featuring all of the functionality of the Cisco Internetwork Operating System (Cisco IOS) software, Cisco's 2524 and 2525 routers are completely scalable. These access routers also offer, for the first time in Cisco's 2500 series, an integrated Network Terminal (NT1) device, providing a complete solution for ISDN users in North America.

"Cisco continues to expand its market-leading 2500 series router family to offer customers increased functionality and modularity, simplifying the installation and management of remote access sites," said Kevin Kennedy, division director in the company's Access Business Unit. "Plus, through a single vendor, corporations and ISPs can select just the modules they require to implement new sites efficiently and cost-effectively."

Unattended Remote Access Made Easy

Cisco's integrated DSU/CSU and ISDN modules provide a compact, self-contained unit without the usual clutter of external devices and cables. Plus, the intelligent DSU/CSU and ISDN modules can be remotely managed from a central location using Cisco's built-in Simple Network Management Protocol (SNMP) to speed problem resolution and avoid on-site visits. These benefits make the 2524 and 2525 routers an ideal solution for unattended remote sites or sites without an information systems (IS) or telecommunications professional.

Fully scalable for any WAN technology, such as ISDN, Digital Data Services (DDS), Switched 56K, Frame Relay packet switching, or fractional/full T1 leased line services, the Cisco 2524 and 2525 routers each accept two synchronous serial plug-in modules and one ISDN module. The two synchronous WAN interface slots can accommodate any of four DSU/CSU modules, making the 2524 and 2525 routers the perfect solution for environments that need to reserve one port for Synchronous Data Link Control (SDLC) or bisynchronous protocols and the second port for Frame Relay or leased line links to headquarters. The routers also feature optional plug-in ISDN modules for both ISDN BRI or ISDN BRI with NT1. All of the modules for the Cisco 2524 and 2525 are user-installable and field-upgradeable, allowing customers to easily add or modify WAN functionality as needed. The Cisco 2524 includes an Ethernet interface, while the Cisco 2525 includes a Token Ring interface.

The routers also provide a number of bandwidth optimization features, including 4:1 data compression over leased lines, packet-switched and circuit-switched WAN20 services, and dial-on-demand routing (DDR) over ISDN and switched 56K lines. For IBM environments, the routers support proxy explorer and NetBIOS name caching to avoid wasting WAN bandwidth on overhead traffic. Snapshot routing and SPX/IPX spoofing keep router and server state data on both sides of the WAN connection to reduce additional traffic.

The new Cisco routers also ensure application availability. Priority out put queuing, for instance, enables network administrators to prioritize traffic by protocol, message size, physical port and Systems Network Architecture (SNA) device. Custom queuing offers the same level of prioritization granularity and ensures that mission-critical traffic receives a guaranteed minimum amount of bandwidth.

Pricing/Availability

The Cisco 2524 and 2525 routers are available immediately in the United States, Canada and South America. These models will not be available in Europe, since DSU/CSU modules there are regulated by the telephone companies. The Cisco 2524 is priced at $900, while the 2525 is priced at $1400.

Optional modules include a two-wire switched 56K DSU/CSU for $900, a four-wire 56K/64K DSU/CSU (DDS or Switched 56K interface) for $700, a fractional/full T1 DSU/CSU for $1600, and a 5-in-1 synchronous serial module for $200. The BRI ISDN interface option costs $600, while the BRI ISDN interface option with integrated NT1 costs $750. All prices are in U.S. dollars and reflect hardware pricing only.
