Key Branch-Office Services
The Cisco Integrated Services Routers are industry-leading platforms that offer unprecedented levels of services
integration. Designed to meet the requirements of the branch office, these platforms provide a complete solution
with voice, video, security, mobility and application services. Businesses enjoy the benefit of deploying a single
device that meets all their needs, reducing capital and operational expenses.
Unified Communications, Collaboration, and Voice-Gateway Services
The Cisco 2900 Integrated Services Router is the foundation for collaboration in the small and midsize branch
office, serving as a critical component of a Cisco's video architecture (Medianet) and enterprise Unified
Communications solution. With embedded voice services and a wide range of supported telephony interfaces, the
Cisco 2900 Series delivers maximum deployment flexibility for the distributed enterprise. Unified communications is
enabled through a rich signaling and media-processing infrastructure, including a variety of protocols, media
interworking, signal and media security, transcoding, conferencing, and QoS. Cisco Integrated Services Routers
also feature a wide range of voice-gateway interfaces, supporting a broad array of signaling and physical network
interfaces.
The Cisco 2900 Series enables a full range of existing and emerging video services, with scaling improvements to
support Cisco TelePresence
extends these capabilities for business-to-business TelePresence communications. The Cisco 2900 Series adds
support for the new Cisco High-Density Packet Voice Digital Signal Processor (DSP) Module (PVDM3), which has
been optimized for voice and video support. The new PVDM3 modules support all voice-gateway functions of
earlier generations of PVDMs and add higher density and more processing power to support emerging rich-media
applications. The Cisco 2900 Series provides 2 or 3 onboard PVDM3 slots, depending on the platform.
Cisco Unified Communications Manager Express and Survivable Remote Site Telephony
The Cisco Integrated Services Routers natively provide optional unified communications services within the Cisco
IOS Software, minimizing the IT hardware footprint and total cost of ownership at the branch office. Cisco Unified
Communications Manager Express (CME) provides a broad range of IP private-branch-exchange (PBX) and key-
system features integrated into the router for the small and midsize branch office. Cisco Survivable Remote Site
Telephony (SRST), also inherently available in Cisco IOS Software, and an option on the Cisco 2900 Series, helps
ensure that branch-office employees have uninterrupted telephony services and features, even if the connection to
a centralized Cisco Unified Communications Manager is disrupted.
