Cisco 4000 mid-range router family gains new interface modules: ATM, high-density Ethernet.SAN JOSE, Calif.--(BUSINESS WIRE)--July 10, 1995--Cisco Systems today introduced two new interface cards for its mid-range Cisco 4000 family of three-slot modular routers. In addition to bringing ATM functionality to the family for the first time, the company has tripled the 4000 line's Ethernet connection density with a new six-port Ethernet card. The new ATM and six-port Ethernet modules operate with the Cisco 4500 router. Cisco today also is introducing new ISDN PRI modules for the 4000 and 4500 (see accompanying release). Kevin Kennedy, Cisco director of marketing for remote access products, said, "The new interfaces make the Cisco 4500 a perfect solution for providing LANs with low-cost ATM connectivity. A Cisco 4500 with six Ethernet ports and an ATM interface is priced as low as $23,200. And with the Cisco Internetwork Operating System (Cisco IOS(tm)), users get the complete array of Cisco IOS protocols, rather than the typical IP-only support of competitive products." ATM OC-3 STS-3c/STM-1 Network Processor Module Cisco's new ATM OC-3 STS-3c/STM-1 Network Processor Module for the Cisco 4500 performs 155-Mbps single-mode and multimode data transmission and native ATM cell processing. The card eliminates the need for an external ATM DSU 1. (communications) DSU - Data Service Unit. 2. DSU - Disk Subsystem Unit (Artecon). 3. (humour) DSU - Dwarf Storage Unit. . As part of the CiscoFusion architecture, and with the Cisco IOS for ATM, the card supports RFC (Request For Comments) A document that describes the specifications for a recommended technology. Although the word "request" is in the title, if the specification is ratified, it becomes a standards document. 1483 Multiprotocol Encapsulation over ATM Multiprotocol Encapsulation over ATM is defined by the specification RFC 2684. Through the use of ATM Adaptation Layer 5 and Logical Link Control (LLC) Subnetwork Access Protocol (SNAP), multiple protocols can be differentiated inside of ATM Cells. and classical IP over ATM as defined in RFC 1577. Later this year, the module will support ATM Forum LAN Emulation (LANE). LANE, which allows higher-layer protocols to operate unmodified over ATM, enables the creation of virtual LANs. The new ATM interface also supports point-to-multipoint signaling, which eliminates the need for multiple point-to-point circuits in broadcast applications such as multimedia. Six-Port Ethernet Network Processor Module Cisco's six-port Ethernet Network Processor Module for the Cisco 4500 provides six 10Base-T ports, tripling the density of the existing two-port card. With three six-port modules installed, the router can connect up to 18 Ethernet segments. Alternatively, two Ethernet modules and an ATM or FDDI (Fiber Distributed Data Interface) Often pronounced "fiddy," it was a LAN and MAN access method that had its heyday in the mid-1990s. FDDI was an ANSI standard token passing network that transmitted 100 Mbps over optical fiber up to 10 kilometers. interface provide economical access for 12 Ethernets to an ATM or FDDI backbone. The use of Cisco's Hot Standby Router Protocol Hot Standby Router Protocol (HSRP) is a Cisco proprietary redundancy protocol for establishing a fault-tolerant default gateway, and has been described in detail in RFC 2281. (HSRP (Hot Standby Router Protocol) A protocol from Cisco for switching to a backup router in the event of failure. See VRRP. HSRP - Hot Standby Routing Protocol ) with dual 4500s lets users build highly robust, redundant networks for applications requiring maximum availability. Pricing/Availability The OC-3 ATM Network Processor Module, available immediately, is priced at $9,500 for single-mode fiber and $11,500 for multimode fiber. The six-port Ethernet Network Processor Module will be available in August for $6,000. All prices are U.S. list. Additional modules currently available for the Cisco 4000 family support Ethernet, Token Ring, FDDI, serial, ISDN BRI and ISDN PRI interfaces. With more than 80,000 units installed worldwide, the Cisco 4000 is the most widely sold modular router in the industry.
