CISCO/라우터 & 라우팅 시스템 2007/05/05 21:15
CISCO ENHANCED CONFERENCING AND TRANSCODING FOR VOICE GATEWAY ROUTERS

Cisco® Enhanced Conferencing and Transcoding for Voice Gateway Routers provides conferencing and transcoding capabilities in Cisco IOS® Software-based gateways using the onboard Cisco Packet Voice/Fax Digital Signal Processor Modules on the Cisco 2800 and 3800 series voice gateway routers. This capability is also supported on Cisco voice gateway router platforms using the Cisco IP Communications Voice/Fax Network Module and the Cisco IP Communications High-Density Digital Voice/Fax Network Module. This feature is delivered in Cisco IOS Software and operates in conjunction with Cisco CallManager.

The Cisco Enhanced Conferencing and Transcoding for Voice Gateway Routers feature provides enhanced multiservice support for Cisco routers in a Cisco CallManager network. This is accomplished by enabling audioconferencing and transcoding functions in access routers. This single-package solution simplifies deployment, eases administration, and helps deliver tangible cost savings by locating conference resources in the branch to reduce WAN utilization. This feature further minimizes costs by using transcoding services to reduce bandwidth needs.
An integral part of Cisco AVVID (Architecture for Voice, Video and Integrated Data), Cisco Systems® IP telephony offers feature-rich telephony services on a fully converged IP network. Using Cisco 2800 and 3800 series onboard digital signal processor (DSP) capability and also available on the Cisco IP Communications Voice/Fax Network Module (NM-HD) and the Cisco IP Communications High-Density Digital Voice/Fax Network Module (NM-HDV2), the Cisco Enhanced Conferencing and Transcoding for Voice Gateway Routers feature preserves all the WAN, public switched telephone network (PSTN), and private branch exchange (PBX) access capabilities while adding conferencing and transcoding functions. The feature, integrated with Cisco CallManager, also provides Cisco CallManager failover, reporting, and management.

AUDIOCONFERENCING SERVICES

In a traditional circuit-switched voice network, all voice traffic goes through a central device (such as a PBX system), which provides audioconferencing services as well. Because IP phones transmit voice traffic directly between phones, a network-based conference bridge is required to facilitate multiparty conferences. In an IP telephony network using Cisco CallManager, the Cisco Enhanced Conferencing and Transcoding for Voice Gateway Routers feature provides the conference bridging service. This feature also supports these services:

• Cisco CallManager Meet-Me and ad-hoc conferences with up to eight participants

• Substantial scalability in the number of conferences supported based on the number of Cisco Packet Voice DSP Fax/Voice Modules (PVDM2s) employed

• G.711 a/u-law, G.729, G.729a, G.729b, G.729ab, GSM FR, GSM EFR participants joined in a single conference

• Easy deployment of conference resources in routers across the network; this provides a local conference resource, reduces WAN utilization, and improves voice network performance

Figure 1. Conferencing

TRANSCODING SERVICES

Transcoding enables two important functions in an IP telephony network. The first is to save on WAN utilization and attendant costs. This is accomplished by compressing voice traffic across the WAN. The second is to enable communication between different devices that support different codecs. Table 1 indicates which transcoding algorithms the Cisco Conferencing and Transcoding for Voice Gateway Routers feature supports.

PLATFORM SUPPORT AND SOFTWARE REQUIREMENTS

Cisco Enhanced Conferencing and Transcoding for Voice Gateway Routers provides the following platform support and requires the following software:

• Support is provided onboard on the Cisco 2800 and 3800 series voice gateway routers. This feature is also supported on platforms using the Cisco IP Communications Voice/Fax Network Module and the Cisco IP Communications High-Density Digital Voice/Fax Network Module.

• Scalable performance using the Cisco PVDM2.

• Cisco IOS Software Release 12.3(8)T4 with the IP Voice feature set is required for the Cisco 2800 Series voice gateway routers. Cisco IOS Software Release 12.3(11)T with IP Voice is required for the Cisco 3800 Series voice gateway routers. Cisco IOS Software Release 12.3(8)T with IP Voice is required for the Cisco IP Communications Voice/Fax Network Module and Cisco IP Communications High-Density Digital Voice/Fax Network Module. Conferencing using the PVDM2-8 requires Cisco IOS 12.3(11)T1.

• Cisco 2801, 2811, 2821, 2851, 3825, and 3845 voice gateway routers require Cisco CallManager Version 4.0(2a) SR1 for full feature support including Media Termination Point (MTP). However, Cisco CallManager Version 3.3(5) may be used on the Cisco 2811, 2821, 2851, 3825, and 3845 voice gateway routers when MTP support is not needed and conferencing and transcoding support is sufficient.

• Cisco IP Communications Voice/Fax Network Module and Cisco IP Communications High-Density Digital Voice/Fax Network Module require Cisco CallManager Version 4.0(1) for full feature support including MTP. However, Cisco CallManager Version 3.3(4) may be used when MTP support is not needed and conferencing and transcoding support is sufficient.

CAPACITY PLANNING

DSPs are built directly onto the Cisco IP Communications Voice/Fax Network Module. On the Cisco IP Communications High-Density Digital Voice/Fax Network Module, DSPs are contained on PVDM2s, which are inserted onto the network module. On the Cisco 2800 and 3800 series voice gateway routers, DSPs are contained on PVDM2s, which are inserted directly onto the motherboard. Each DSP is individually configurable to support either conferencing or transcoding and standard voice termination. The total number of conferencing, transcoding, and voice termination sessions is limited by capacity of the entire system, which includes the DSPs, platform, physical voice interface, and Cisco CallManager. Table 2 describes maximum capacity. Actual capacity may be smaller based on the total system design.

Cisco EtherSwitch 4- and 9-Port High-Speed WAN Interface Cards

CISCO/라우터 & 라우팅 시스템 2007/05/05 21:14
CISCO ETHERSWITCH 4- AND 9-PORT HIGH-SPEED WAN INTERFACE CARDS FOR CISCO 1800 (MODULAR), CISCO 2800, AND CISCO 3800 SERIES INTEGRATED SERVICES ROUTERS

PRODUCT OVERVIEW

The 4- and 9-port Cisco® EtherSwitch® 10/100 high-speed WAN interface cards (HWICs) supported on the Cisco 1800 (modular), Cisco 2800, and Cisco 3800 series integrated services routers offer small-to-large-size businesses and enterprise branch office customers the option to integrate switching and routing in one device. This combination offers ease of configuration, deployment, and management while using the powerful characteristics of Cisco routing and Cisco Catalyst® switching features.
The modular 4- and 9-port Cisco EtherSwitch HWICs provide line-rate Layer 2 switching across Ethernet ports using Cisco IOS® Catalyst Software. The 4-port Cisco EtherSwitch HWIC has four 10/100 switched Ethernet ports, with options for inline power support on all four ports. The 9-port Cisco EtherSwitch HWIC has nine 10/100 switched Ethernet ports, with options for inline power support on 8 of the 9 ports. The ninth port does not support inline power but can be used as a regular switch port for trunking and other normal data applications. Note: The optional inline power support on the 4- and 9-port HWICs is offered on the Cisco 2800 and Cisco 3800 series. It is not offered on the Cisco 1841 of the Cisco 1800 Series (modular). Features such as port autosensing, quality of service (QoS), VLAN support from 802.1P and 802.1Q standards, and 802.1D spanning tree protocols are standard on the Cisco EtherSwitch HWIC. The Cisco EtherSwitch HWICs are available in standard 4- or 9-port 10/100BASE-TX switch HWIC and Power-over-Ethernet (PoE) configurations. The PoE configurations consist of a 4- or 9-port 10/100BASE-TX switch and a 4- or 8-port inline power module daughter card. The power module daughter card houses a power controller for detecting, classifying, and enabling power on 802.3af-compliant powered devices attached to the HWICs. The inline powered version of the Cisco EtherSwitch HWIC can power Cisco IP phones, Cisco wireless access points, or any other IEEE 802.3af-compliant device. The optional inline power support on the 4- and 9-port HWICs on the Cisco 2800 and Cisco 3800 series of integrated services routers requires the use of a field-replaceable inline power supply. (Refer to Figure 1.)

APPLICATIONS

Small Branch Data Only

Figure 2 shows an example of a deployment for a small-to-large enterprise branch office.

Figure 2. Typical Data-Only Deployment for a Small-to-Large Enterprise Branch Office

A Cisco EtherSwitch HWIC in an enterprise branch data deployment scenario provides the flexibility of integrated routing and switching functions in one unit for low port densities. This deployment provides high-speed connections between individual desktops, servers, and other network resources in a single unit for Layer 2 and allows WAN connection at Layer 3 through the router. The Cisco EtherSwitch HWIC with a Cisco 1841 or a Cisco 2800 Series integrated services router also provides an ideal replacement solution for Cisco 2505, Cisco 2507, or Cisco 2516 users whose requirements have expanded beyond the existing Cisco 2500 router or hub capabilities.
Figure 3 shows an example of a typical converged deployment for a small-to-large enterprise branch office with IP phones.

Figure 3. Typical Converged Deployment for a Small-to-Large Enterprise Branch Office with IP Phones

Converged IP Communications in a Small-to-Large Enterprise Branch Office with Data Devices and IP Phones

The 4- or 9-port Cisco EtherSwitch HWICs when combined with analog or digital voice modules for the Cisco 2800 and Cisco 3800 series routers provide a small-to-large enterprise branch office infrastructure for IP telephony deployments. This solution can be combined with Cisco CallManager Express IP Telephony or the Cisco IOS Software Survivable Remote Site Telephony (SRST) solution. SRST runs on the local branch office router, allowing it to automatically detect a failure in the network, and initiates a process to intelligently autoconfigure the router to provide call-processing backup redundancy for the IP phones in that office. In the case of a Cisco CallManager Express deployment, call-processing features are offered on the branch router without a centralized call manager.
The Cisco EtherSwitch HWIC with the optional internal chassis provides IP phone power and phone discovery for IP phones. In addition, the Cisco EtherSwitch HWIC supports separate VLAN configuration for IP phones. The auxiliary VLAN feature allows network administrators to segment phones into separate logical networks, even though the data and voice infrastructures are physically the same. The phone discovery feature allows the Cisco 4- and 9-port EtherSwitch HWICs (product numbers HWIC-4ESW-POE or HWIC-D-9ESW-POE) to automatically detect the presence of an IP phone and supply inline power.

FEATURES AND BENEFITS

Table 4 gives the architecture, features, and benefits of the Cisco 4- and 9-port HWICs.

Table 4. Architecture, Features, and Benefits of 4- and 9-Port Cisco EtherSwitch HWICs

Feature

Benefit

4 or 9 10BASE-T/100BASE-TX Ports

These ports deliver up to 200 Mbps of aggregate bandwidth (full duplex) for forwarding Layer 2 traffic on each port.

Autosensing, Autonegotiation, and Auto-MDIX (Automatic Media-Dependant Interface Crossed Over)
· The Autosensing feature allows the switch to detect the speed of the attached device and automatically configure the port for 10- or 100-Mbps operation.
· The Autonegotiation feature allows the switch to automatically select half- or full-duplex transmission mode to optimize bandwidth on all the ports of the HWIC
· The Auto-MDIX feature allows the switch to automatically detect cable type (straight through vs. crossover) between the attached Ethernet device and switch line pairs.
Integrated Switching

Integrated switching provides fewer points of management for remote and small branch offices.

802.1P QoS (Traffic Prioritization)

This feature provides support for QoS based on the IEEE class of service (CoS) and port-based prioritization, allowing the switch to change the CoS settings of tagged packets on a per-port basis.

802.1Q Trunking

This feature allows the setup of separate VLANs with tagged and untagged framing; trunking is used to save ports when creating a link between two devices implementing VLANs; VLANs allow segmentation of the LAN.

802.1D Spanning Tree Protocol

This Layer 2 link-management protocol provides path redundancy while preventing undesirable loops in the network; it simplifies network configuration and improves fault tolerance.

Voice VLAN (VVLAN)

VVLANs help enable Cisco IP phones to place voice and data in their own separate VLANs. The HWIC switch port is manually configured as a trunk port to support voice and data VLANs on the same port. The switch then uses Cisco Discovery to dynamically configure the Cisco IP phones.

802.1x Authentication

This client-server-based access control and authentication protocol restricts unauthorized devices from connecting to a LAN through publicly accessible ports.

PoE (Option)

Cisco EtherSwitch technology with the appropriate inline power module and internal power supply can power Cisco IP phones and wireless access points. Support is provided for both IEEE 802.3af PoE and Cisco prestandard inline powered devices. The ninth port of the 9-port HWIC (part number HWIC-D-9ESW-POE) cannot be used for PoE applications. The PoE option is not available on the Cisco 1841 router.

Multicast Management Support

This feature offers Internet Group Management Protocol (IGMP) snooping in hardware for management support.

Simple Network Management Protocol (SNMP) Management

SNMP allows management of the MIB through a MIB browser.

Cisco IOS Software Command-Line Interface (CLI)

This feature provides configuration through the Cisco IOS Software CLI and provides a common user interface for all the router functions.

CiscoWorks Support
· CiscoWorks network management software helps enable manageability on a per-port and per-switch basis, providing a common management interface for Cisco routers, switches, and hubs.
· SNMPv1, v2, and v3 (noncryptographic) and Telnet interface support delivers comprehensive in-band management, and a CLI management console provides detailed out-of-band management.
· Cisco Discovery Protocol Versions 1 and 2 help enable a CiscoWorks network management station to automatically discover the switch in a network topology.
· Support is provided by the CiscoWorks LAN Management Solution.
Cisco Discovery Protocol Versions 1and 2

This protocol enables a CiscoWorks network management station to automatically discover the switch in a network topology.

VLAN Trunking Protocols (Client, Server, and Transparent Modes)

The Cisco Virtual Lan Trunking Protocol (VTP) supports dynamic VLAN configuration across Cisco switches.

Cisco Secure Router and Device Manager (SDM)-Based Configuration and Device Management
· This feature simplifies initial configuration of a switch through a Web browser, eliminating the need for more complex terminal emulation programs and CLI knowledge.
· Cisco SDM reduces the cost of deployment by helping less-skilled personnel set up switches quickly and simply.
Status LEDs

Two LEDs per port provide convenient visual indication of the switch port and inline power status.

SUMMARY AND CONCLUSION

The 4- and 9-port Cisco EtherSwitch HWICs (part numbers HWIC-4ESW and HWIC-D-9ESW) are managed 10/100BASE-T Layer 2 switches in a HWIC form factor for the Cisco 1800 (modular), Cisco 2800, and Cisco 3800 series integrated services routers. The 4-port HWIC comes in a single-wide form factor, and the 9-port HWIC in a double-wide form factor. The switch supports the IEEE 802.1D Spanning Tree Protocol and can be used to connect up to 4 or 9 LANs with up to 15 IEEE 802.1Q-based VLANs (802.1Q). Note: Both HWICs-the 4- and 9-port HWICs-support up to 15 VLANs. They also can be optionally configured to provide 4 or 8 ports of inline power for 802.3af- or Cisco PoE-capable devices. The PoE support is not available on the Cisco 1841 router.

Cisco IP Communications Services for Cisco Integrated Services Router Platforms

CISCO/라우터 & 라우팅 시스템 2007/05/05 21:13
CISCO IP COMMUNICATIONS SERVICES FOR CISCO INTEGRATED SERVICES ROUTER PLATFORMS

The Cisco Integrated Services Router is the ideal platform for delivering IP Communications in enterprise branch offices, commercial offices, and small or medium-sized business offices. Through the integration of security, voice gateway, call processing, voice mail, automated attendant, conferencing, and transcoding capabilities Cisco Integrated Services Router platforms deliver a complete office IP Communications solution.

PRODUCT OVERVIEW

Customers of all sizes want opportunities to converge best-of-class data, voice, and security services into a single system that enables rapid services deployment, as well as opportunities to protect, grow, and optimize their businesses. With Cisco® Integrated Services Router platforms, enterprise branch, commercial offices and small or medium-sized offices can use the industry's broadest, most comprehensive voice and security services, directly embedded and integrated inside the industry's leading routing platform for maximum performance and resiliency. Cisco Integrated Services Router platforms (Cisco 2801, 2811, 2821, 2851, 3825, and 3845) provide the appropriate-sized solution for the smallest to largest customers, scaling to meet the most demanding enterprise environments while providing the performance and architecture for services available today and in the future.
The first company to offer a converged voice, security, and data solution engineered from the ground up for wire-speed concurrent services, Cisco Systems® delivers to customers of all sizes the IP Communications and security services and densities they need, specifically sized for their data requirements.
Cisco Integrated Services Router platforms embed voice and security functions directly inside the router, enabling customers to deploy advanced services simply by installing digital signal processors (DSPs) and advanced integration modules (AIMs) for IP telephony conferencing, voice gateways, Cisco Unity™ Express voice mail and automated attendant, as well as industry-standard security. For call processing, customers can enable the company's award-winning Cisco CallManager Express solution as part of Cisco IOS® Software, and easily reconfigure the same software at any time to support Cisco Survivable Remote Site Telephony (SRST) for centralized call processing with Cisco CallManager, the industry's leading solution for enterprise-class IP telephony.
By embedding proven voice technologies inside the platform, Cisco Integrated Services Router platforms free up integrated modular slots, enabling customers to take advantage of new high-speed slots such as the high speed WAN interface card (HWIC) and enhanced network module (NME) for additional services, interfaces, and densities.
The innovative extension voice module (EVM) slot on both the Cisco 2821 and 2851 routers provides significant increases in analog and Basic Rate Interface (BRI) voice densities within a single platform, scaling to as many as 24 foreign exchange station (FXS) interfaces and 12 foreign exchange office (FXO) interfaces (these EVM modules also are supported on the Cisco 3825 and 3845 routers). All Cisco Integrated Services Router platforms natively support voice interface cards (VICs) in all HWIC slots and use the optional packet voice DSP modules (PVDMs), which are installable on the motherboard of the router itself. Figures 1 and 2 show IP Communications services available on the Cisco 2851 and Cisco 3845, respectively.
With Cisco Integrated Services Router platforms and Cisco's systems approach to voice, security, and data services, enterprises easily can implement tiered services immediately or build voice services incrementally without sacrificing performance or room for future growth. Small and medium-sized businesses now can deploy data, security, and IP Communications requirements in a single system that is easy to install and configure for reduced cost and complexity. Service providers can extend managed voice and data services to customers of all sizes in a single routing system that scales as customer needs change.
Only Cisco provides customers with a complete, converged solution built on more than 20 years of IP innovation and leadership and proven data, voice, and security solutions.

APPLICATIONS

Cisco integrated services router platforms operate as toll bypass voice gateway routers for businesses to avoid telephony tolls by routing traditional private branch exchange (PBX) traffic across a corporation's IP network. This implementation also is the foundation for migration from a legacy PBX environment to a purely converged IP Communications network. Figure 3 shows Cisco Integrated Services Router platforms used in a voice toll bypass network.

Figure 3. Cisco Integrated Services Router Platforms Used in a Voice Toll Bypass Network

Cisco Integrated Services Router platforms are the foundation for enterprise branch offices and commercial offices deploying IP telephony with SRST for failover call processing. In this deployment, voice mail and automated attendant services can be delivered directly inside the Cisco integrated services router using Cisco Unity Express or delivered centrally using Cisco Unity software. Customers can also implement Secure SRST to enable authentication and encryption support for both signaling and media transmission during a WAN outage.
Loosely coupled offices or semiautonomous offices are ideal locations for the "right size" IP telephony services within a Cisco integrated services router, which delivers the security and routing requirements for that same location. Integrating Cisco CallManager Express and Cisco Unity Express within the Cisco integrated services router management simplifies service and maintenance Figure 4 shows the Cisco Integrated Services Router platforms used for IP telephony in branch, commercial or small offices. Cisco CallManager Express can also be transparently integrated with a central Cisco CallManager for maximum configuration flexibility.

KEY FEATURES AND BENEFITS

PVDM Slots on Motherboard

Embedded modularity using any Cisco PVDM2 product (PVDM2-8, PVDM2-16, PVDM2-24, PVDM2-32, or PVDM2-64) on any Cisco integrated services router platform motherboard delivers conferencing, transcoding, and voice termination without the need to use a network module or AIM. Installing Cisco PVDM2 products inside the Cisco integrated services router provides these services for both voice over IP traffic along with time-division multiplexing (TDM) traffic. TDM interfaces can be terminated by using VICs, VWICs or an EVM (EVM is supported only on the Cisco 2821, 2851, 3825, and 3845 routers) installed natively on the Cisco integrated services router.

Dedicated EVM Slot on Cisco 2821 and Cisco 2851 Routers

Exceptional analog and BRI telephony densities are achieved through the use of a specialized EVM, which frees expansion network module slots for additional services and increased densities of voice, LAN and WAN interfaces.
Using PVDM slots on the motherboard in conjunction with the EVM card, customers have the option to offer voice services within the same platform that one would normally deploy for security and routing without the need to add a second router.

Media Authentication and Encryption

Media authentication and encryption features on Cisco's portfolio of Access Routers ensures that voice conversations terminating on either TDM or analog voice gateway ports are protected from eavesdropping. These reliable, scalable features provide a secure environment for IP communications over a LAN (local area network) or WAN (wide area network).

Dedicated Echo Cancellation Slot on 2nd Generation Multiflex Trunk Voice/WAN Interface Cards

The Cisco 2nd Generation 1 and 2 Port T1/E1 Multiflex Trunk Voice/WAN Interface Cards (VWIC2-MFT family) have an on-board slot for a Multiflex Trunk Dedicated Echo Cancellation Module (EC-MFT-32 and EC-MFT-64).
These optional daughter cards provide a dedicated hardware resource that runs Cisco's Enhanced ITU-T G.168 Echo Cancellation feature, which can be used in select network conditions when the existing voice resources are constrained. The Dedicated Echo Cancellation module's processing and memory resources enables the echo canceller to be configured with an extended 128ms echo tail buffer, providing a robust echo cancellation performance for demanding network environments.
