The Cisco uBR914 Cable Data Service Unit (DSU) provides a simple migration to cable-based broadband access for businesses currently using telephone company full and fractional T1/E1 services. The Cisco uBR914 can also be used to give a cable interface to all of Cisco"s access routers. This allows cable operators to extend the services they provide to their customers. Investments in existing access routers are optimally leveraged since the Cisco uBR914 uses the same serial interface on the router that was previously used to connect to a channel service unit (CSU)/DSU. The Cisco uBR914 offers tremendous flexibility in providing cable WAN connectivity for any router that supports V.35, X.21, or EIA-530 serial WAN interfaces, and will provide alternative interfaces through its modular access router interface slot in the future. The Data-over-Cable Service Interface Specification (DOCSIS) 1.1-based architecture of the Cisco uBR914 provides the flexibility to connect with any DOCSIS-qualified cable headend and offers the quality of service (QoS) and security that business users require. By leveraging other Cisco small and medium-sized business routers, Cisco uBR914 provides users with access to advanced capabilities including high-speed virtual private networks (VPNs), private branch exchange (PBX)-based voice over IP (VoIP) services, and service-level agreement (SLA) support. The 19-inch rack-mount form factor includes support for the Cisco redundant power supply via an upgrade kit for added service reliability.

Product Overview
Key Features and Benefits
|
Key Feature |
Benefit |
|---|---|
|
12-in-1 Serial Access Router Interface Card that supports V.35, X.21, and EIA-530 Serial Protocols, and Supports HDLC, PPP, and Frame Relay Protocols at Layer 2 |
Provides cable WAN connectivity to any access router that supports V.35, X.21, or EIA-530 serial protocols Cisco products supported with the uBR914 include the Cisco 1600, 1700, 2600 or 3600 access routers that have an installed WAN interface card (WIC) such as the WIC-1T or WIC-2T, or Cisco 2500 and 4000 routers with a serial interface Helps eliminate the need for forklift upgrades of existing routers being used by businesses by connecting to the same interface used by telco CSU/DSU equipment |
|
Modular Access Router Interface Set |
Flexibility to provide serial interface to routers today with ability to support other interfaces in the future |
|
Redundant Power Supply (RPS) Support via Upgrade Kit |
Increased Service Reliability |
|
Separate Device from Access Router |
Provides a clean demarcation point between cable provider networks and end-user networks Simplifies installation since cable provider does not have to deal with customer local area network (LAN) issues Cable operators can use one type of cable DSU to connect to the variety of routers being used by businesses today |
|
DOCSIS 1.1-Based Design |
Easily connects to standards-based cable modem termination systems (CMTS) in the headend while offering QoS and 56-bit wire speed data encryption standard (DES) encryption over the cable plant |
|
Leverages Voice Ports of Cisco 1750, 2600, and 3600 Series Routers |
Existing PBX and key systems gain access to VoIP connectivity over the cable plant Businesses can save money while getting bundled voice and data service from cable operator Eliminates the need for a call agent by leveraging call features on PBX |
|
SLA Assurance Agent Support in Cisco Access Routers |
Monitor network performance by measuring key SLA metrics such as response time, network resources, availability, jitter, connect time, packet loss, and application performance |
|
Multiprotocol Traffic Support |
Ability to route traffic such as AppleTalk or Novell IPX from branch offices to headquarters over the cable network (encapsulated in IP) |
|
Layer 3 QoS Mechanisms including RED and WFQ |
Improves QoS customer satisfaction |
|
True Split-Management Capability |
Offload the configuration and management of branch office VPNs and firewalls to an enterprise IT department without giving up access to DOCSIS configuration files and service classes |
|
Common Command-Line Interface (CLI) |
Reduces training and education requirements |
