Key Features And Benefits

PVDM Slots on Motherboard

Embedded modularity using any Cisco Packet Voice/Fax DSP Module 2 (PVDM2) product (PVDM2-8, PVDM2-16, PVDM2-24, PVDM2-32, or PVDM2-64) on any Cisco Integrated Services Router platform motherboard delivers ISDN video termination without the need to use a network module or advanced integration module (AIM). Installing Cisco PVDM2 products inside the Cisco Integrated Services Router provides these video services by using Basic Rate Interface (BRI) voice interface cards (VICs) and E1/T1 voice/WAN interface cards (VWICs) installed natively on the Cisco Integrated Services Router.

Video-Enabled Cisco Unified CallManager Express

Cisco Unified CallManager Express provides call processing for Cisco IP phones for small or branch-office environments. It enables the large portfolio of Cisco Integrated Services Routers to deliver IP telephony features that are commonly used by business users to meet the voice and video communications requirements of the small or medium-sized office. Cisco Unified CallManager Express enables the deployment of a cost-effective, highly reliable communications system using a single Cisco Integrated Services Router using Cisco IOS Software.
IP telephony is currently undergoing tremendous growth, accelerated by access to value-added features and applications only IP telephony can provide to the end user. Additionally, the cost benefits of converging data, voice, and video onto a single network are adding to the rapid acceptance of this technology. Because it is integrated into a router, Cisco Unified CallManager Express enhances the advantages of convergence by offering the following unique benefits:

Cost-effective operations through a single, integrated voice-and-data platform for all branch-office needs-Highly reliable routers, including the Cisco 2800 and 3800 Series Integrated Services Router platforms, provide robust quality of service (QoS), network security, encryption, firewall, and network modules that deliver content networking and enhanced VPN services to address branch- and small-office business needs. The system delivers integrated IP telephony, voicemail, and automated-attendant functions, allowing customers to deploy one device to address all their business needs; simplifying management, maintenance, and operations; and delivering a lower total cost of ownership (TCO).

Sophisticated key system and private-branch-exchange (PBX) capabilities-Small offices have different workflows and require specialized features to support their work practices. Cisco Unified CallManager Express delivers a robust set of telephony features for the small office, and delivers unique value-added capabilities through Extensible Markup Language (XML) that enhance the productivity of the end user and the business-and these capabilities cannot be delivered by traditional systems.

Interoperability with Cisco Unified CallManager-Customers can deploy Cisco Unified CallManager at larger sites and deploy Cisco Unified CallManager Express at branch-office locations where local call processing is required. Using H.323 or Session Initiation Protocol (SIP), trunking calls can be routed over the WAN with calling party name and number information, plus compressed voice for better WAN bandwidth usage.

Investment protection and ease of upgrade to centralized call-processing systems-Through a simple software configuration change on the router, a system with Cisco Unified CallManager Express can be converted to a highly available survivable telephony gateway for a remote site in a centralized Cisco Unified CallManager deployment architecture. This flexibility helps ensure full investment protection for successful businesses that might outgrow the system capacity.

Remote maintenance and troubleshooting-Customers can use the industry-standard Cisco IOS Software command-line interface (CLI) or user-friendly GUI to configure and administer Cisco Unified CallManager Express.

Cisco Unified CallManager Express allows a Cisco Integrated Services Router to provide call processing for locally attached IP and analog phones. All the necessary files and configurations for IP phones are stored internally on the router, providing a single platform solution. In addition, the solution offers a robust set of public-switched-telephone-network (PSTN) interfaces, a wide selection of WAN interfaces, integrated voicemail and automated attendant, and a full phone portfolio. Cisco IOS Software offers industry-leading voice features designed for IP-based telephony systems, such as H.323 and SIP signaling, advanced QoS, and interworking with an H.323 gatekeeper or SIP proxy server-all available for use with Cisco Unified CallManager Express deployments. In addition, integrated functions such as channel service unit/digital service unit (CSU/DSU) and Network Termination 1 (NT1) devices are available with digital PSTN interface cards to provide flexible and robust voice services.

Cisco Unified SRST Video Gateway

The Cisco Unified Communications system uses Cisco Unified CallManager in combination with Cisco Unified SRST, which is embedded within Cisco IOS Software, to help provide high-availability IP telephony to branch offices. When access to Cisco Unified CallManager from the branch office is impeded, for example, as a result of a WAN link failure, Cisco Unified SRST provides voice and video telephony backup services to help ensure that the branch office has continuous telephony service over the Cisco network infrastructure deployed in the branch. To provide the video survivability services, an ISDN H.320 video gateway function has been added to the existing voice DSP and interface technology on the integrated services router platform. This new gateway function allows for video calls to use the existing ISDN interfaces for simultaneous and ISDN video functions. The enhanced reliability provided by Cisco Unified SRST makes the Cisco Unified Communications system a cost-effective solution to help ensure telephony operation to all users in an organization, whether they are located in the headquarters or in a branch office.
