DATA SHEET

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 2 nd 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.
