voice, video and data. This is first achieved by consolidation in the wide-area network (WAN), where current costs are the highest. Cost reductions will also be achieved by integration in the campus and branch office, where private branch exchange (PBX) capital and operations costs are disproportionately high and alternative network PBX functionality is now available. Most importantly, multiservice networking enables key emerging business applications by inherently supporting any type of traffic, and therefore, any type of network application requirements. Increasingly, emerging business applications such as unified voice and e-mail messaging, computer telephony integration (CTI), and desktop video streaming and videoconferencing require variable traffic types to be mixed in a reliable way; which can only be achieved by a true multiservice enterprise network infrastructure.

The Catalyst 6500 Series is the premium Catalyst AVVID platform and continues to enable customers to lead with campus convergence. The Catalyst 6500 lead the industry with the introduction of Fast Ethernet switching with inline power for IP Phones. As the premium AVVID platform, the Catalyst 6500 now provides inline power as standard on the entry-level 48-port 10/100BaseT Ethernet switching modules. Inline Power is 48 Volt DC power provided over standard category 5 UTP cable up to 100 meters. Instead of using wall power, terminal devices such as IP telephones utilize power provided from the Catalyst 6500 switch. This capability gives the network administrator centralized power control, which translates into greater network availability. By deploying Catalyst 6500 switches with Uninterruptible Power Supply (UPS) systems in secured wiring closets, network administrators can ensure that building power outages will not affect network telephony connections. The Inline Power feature will work over customer s existing category 5 UTP installations. The Catalyst Inline Power implementation passes the required domestic and international safety regulations and compliance measures. These modules are fully compliant with 802.3 standard when no Inline Power is supplied. The 802.3 standard does not include specifications for providing power over Ethernet, this omission will be amended by the 802.3af task force; a standard is expected to be available by the end of 2002. Cisco is committed to standards-based operation and will support the IEEE in their efforts to add Ethernet power specifications to the 802.3 Ethernet standard. device not designed to use Inline Power. Therefore, network administrators can depend upon automatic and centralized control of Inline Power that is safe to deploy and maintain. To support the new demand for phone power provided with the Inline Power feature, the Catalyst 6500 supports a range of chassis power supplies, which include 1300W, 2500W, and 4000W supply options. These chassis power supplies provide power for the system itself and for the IP Phones. Normal configuration requires a single power supply and two for a fully fault-tolerant system. To ensure the most efficient use of power and to keep the wiring closet power provisioning to a minimum, the Catalyst 6500 Series also supports new power management features. The system will ensure the configured power source is not over subscribed Phone discovery ensures there is always sufficient power to operate all phones. Network administrators can now centrally provision and control power and query the switch for available power resources. 24-Port FXS Module: The new Catalyst 6500 Series FXS Analog Interface Module provides up to 24 connections for analog phones and fax machines. Phone Discovery: The Cisco Phone Discovery feature eases the network management burden by automating the Inline Power feature. With Phone Discovery, the Catalyst switch automatically detects the presence of an IP phone and supplies Inline Power. This means that network administrators can maintain centralized control without the need to manually enable each port to supply Inline Power. The Phone Discovery mechanism is intelligent enough to differentiate between an IP phone and an NIC, and will not supply Inline Power to an NIC or other The Catalyst 6500 FXS Analog Interface module provides 24 foreign exchange station (FXS) ports for analog phones, conference room speaker phones, and fax machines. The FXS module provides legacy analog devices with connectivity into the IP network, enabling them to utilize the IP network infrastructure for toll bypass applications and to communicate with devices such as IP Phones and H323 end stations.

also supports fax relay, which enables compressed fax transmission over the IP WAN, preserving valuable WAN bandwidth for other data applications. Quality of Service: The Catalyst 6500 Series provides the performance, scalability, and intelligent services of Cisco IOS software for wiring-closet, enterprise backbone, and service provider applications. The switches are an integral part of the CiscoAssure end-to-end QoS and policy-based security solution. These switches can identify user applications such as voice, enterprise resource planning (ERP) or multicast and classify traffic with the appropriate priority level. They can support admission control in the wiring closet to prevent unauthorized applications from being allowed onto the network. The Catalyst 6500 Series also supports advanced QoS features such as packet classification and marking, scheduling, policing, and congestion avoidance. Catalyst modules provide extensive per-port queuing to guarantee that voice traffic is given highest priority. Dedicated voice queues can be configured such that QoS is maintained end-to-end through the switch and across the network. Network resilience features such as Layer 2 and 3 load balancing, redundant system elements, and fast fail-over mechanisms maintain highest levels of system availability. QoS policies are enforced using Layer 2, 3, and 4 information such as 802.1p, IP precedence, and Layer 4 port numbers. Within Catalyst 6500 switches, multiple queues with configurable thresholds employ weighted random early detection (WRED), weighted round-robin (WRR), and type-of-service/class-of-service (ToS/CoS) mapping mechanisms to ensure that QoS is maintained as packets traverse the network. Resource Reservation Protocol (RSVP) priority mapping can also be used, ensuring timely delivery of time-sensitive intranet applications. These features make the Catalyst 6500 Series the most advanced switches in the industry by providing enhanced intelligent network services at wire speeds. AVVID Voice Campus Core For IP Telephony, the Enterprise Campus Core must provide a voice gateway to the PSTN and Voice Network Services for audio conferencing and audio transcoding. 8-Port Voice T1 and Services Module* *Also available: 8-port Voice E1 and Services Module The new Catalyst 6500 Series 8-Port Voice T1 and Services Module can provide enough voice trunking power to support an entire campus. The Voice T1 and Services Module provides 8 T1 ports (192 channels or DS0 voice trunks) for connections to the PSTN or PBX. As a gateway to the PSTN or legacy PBX, this module provides voice packetization services for delivery to/from the IP network. The module supports voice trunk protocols such as ISDN Primary Rate Interface (PRI) and Channel Associated Signaling (CAS). With a Voice T1 and Services module installed, a single Catalyst 6500 switch can provide enough voice trunking power to support an entire campus.

Catalyst 6000 Voice T1 and Services module provides flexible port by port configurations. In this example, 2 ports are connected to the PSTN while the remaining 6 ports are used to provide network voice services such as conferencing. PSTN 2 Ports Configured as T1 Connections to PSTN Catalyst 6000 Voice T1 and Services Module Furthermore, the Voice T1 and Services module can be used as a valuable shared network resource. Users have the flexibility to use each port for T1 connections or as a network resource that provides voice services such as compression or conferencing (see Figure). For example, a network administrator can configure two ports as T1 connections to the PSTN. The remaining six ports can be used to provide voice compression services. The voice compression services enable voice calls that traverse the IP WAN to be compressed, preserving valuable WAN bandwidth. Voice compression is only one example of the capabilities that will be possible with this module. There is more processing power available on this module than exists in most currently installed PBXs. Future voice services will be developed that will enable new applications to be deployed in tomorrow s advanced multiservice networks. The Catalyst 6500 Advantage New Levels of Network Resilience: 6 Ports Configured to Provide Network Voice Services The Catalyst 6500 Series supports multiple levels of network resiliency and serviceability designed to handle mission-critical applications. To ensure high system availability, the Catalyst 6500 Series supports device-level fault tolerance, to include the following options: Redundant Supervisors Redundant, load-sharing power supplies (AC and DC) Redundant sharing fans Redundant system clocks Redundant uplinks All system elements including power supplies, fans, supervisors, and line-card modules are hot swappable such that elements can be added, removed, or replaced without service interruption of unrelated traffic flows. In dual Supervisor configurations, Cisco Switchover will transfer switch control to the redundant Supervisor within seconds for mission-critical applications requiring maximum network availability. All system elements are also field-replaceable units, maximizing serviceability and minimizing network downtime. For network-level resilience, Catalyst 6500 Series switches also support automatic recovery from failure using Spanning Tree per VLAN, load sharing for faster link convergence using Cisco Fast EtherChannel or Gigabit EtherChannel, and robust routing intelligence provided by Cisco IOS software. Advanced Management Features: Catalyst switches provide advanced network management features necessary for the success and maintenance of a multiservice infrastructure. A unique feature that demonstrates Cisco s advanced IP telephony leadership is the auxiliary VLAN feature. This feature provides automatic VLAN configuration for IP telephones. Auxiliary VLAN Catalyst 6000 automatically provides phone VLAN configuration. Phone VLAN = 200 This feature overcomes the complexity of overlaying a voice topology onto a data network. Network administrators can easily segment phones into separate logical networks, even though the data and voice IP IP Phone: IP Subnet B PC VLAN = 3 Desktop PC: IP Subnet A No End-User Intervention Required Provides the Benefits of VLAN Technology for the Phone Preserves Existing IP Address Structure Uses Standards-Based 802.1Q/p Technology between Switch and Phone All contents are Copyright 1992 2001 All rights reserved.

infrastructure is physically the same. The auxiliary VLAN feature places the phones into their own VLANs without any end user intervention. Furthermore, these VLAN assignments can be seamlessly maintained even if the phone is moved to a new location. The user simply plugs the phone into the switch, and the switch will provide the phone with the necessary VLAN information. By placing phones into their own VLANs, network administrators gain the advantages of network segmentation and control. Furthermore, network administrators can preserve their existing IP topology for the data end stations. IP phones can be easily assigned to different IP subnets using standards-based DHCP operation. With the phones in their own IP subnets and VLANs, network administrators can more easily identify and troubleshoot network problems. Additionally, network administrators can create and enforce QoS or security policies. With the auxiliary VLAN feature, Cisco enables network administrators to gain all of the advantages of physical infrastructure convergence while maintaining separate logical topologies for voice and data terminals, creating the most effective way to manage a multiservice network. The Catalyst 6500 Series delivers a comprehensive set of management tools to provide the required visibility and control in the network. The Catalyst voice modules provide extended management capabilities, statistics, and status information for voice traffic. For instance, users can query the switch to see how many active calls exist. Users can also gather valuable management data about these calls, such as the source/destination module, port, and IP addresses. Centralized management is provided through CiscoWorks and the voice functions are administered from the Cisco CallManager. Cisco CallManager is a Web-based application that can be used to perform centralized configuration and management of the voice modules within the Catalyst 6500 systems. Policy management is achieved through a combination of intelligent, embedded agents on the switches and CiscoWorks2000, a powerful network management application. CiscoWorks2000 will provide policy management for all Cisco network services, including QoS, multicast, security, network resiliency, and mobility of users. Cisco Resource Manager is another Web-based management tool that offers automated inventory collection, software deployment, easy tracking of network changes, views into device availability, and quick isolation of error conditions. Intelligent, embedded agents on Catalyst 6500 Series switches include support for Cisco Discovery Protocol, delivering network topology discovery and mapping and Cisco Virtual Trunking Protocol (VTP), supporting dynamic VLANs and dynamic trunk configuration across all switches. Embedded intelligent Remote Monitoring (RMON) agents on every port deliver powerful traffic monitoring and control four RMON groups are supported per port to include statistics, history, events, and alarms groups.
