BENEFITS OF AN INTEGRATED, FULLY MANAGED SOLUTION
The T1 DSU/CSU WIC enables trouble-free Internet/intranet access with a simple, fully managed, integrated solution from a single vendor. Its ease of configuration and management differentiates it from external or separate DSUs/CSUs. Full management capability and modularity differentiates the T1 DSU/CSU WIC from other integrated router-DSU/CSU solutions, which typically have limited management and fixed configuration. This card delivers flexibility and investment protection, extending the growing family of WICs for Cisco 1700 Series, 2600 Series, 3631, and 3700 Series routers and Cisco ICS 7750 Software.
Reduced Deployment, Management Time, and Costs
Ease of configuration and management-The Cisco T1 DSU/CSU WIC simplifies tasks in the following ways:
• Easily configures via Cisco IOS Software initial setup, a utility that prompts a series of basic configuration questions upon router startup.
• Allows simplified remote and local configuration, management, and troubleshooting of the DSU/CSU from Cisco IOS CLI
–Using the familiar Cisco IOS CLI eliminates the need to learn or use command syntax for an external DSU/CSU
–Convenient Telnet or Secure Shell (SSH) Protocol connection to the router eliminates the need for out-of-band management of external DSUs/CSUs
–Cisco IOS CLI provides extensive DSU/CSU statistics (such as 24-hour history) and troubleshooting capability (such as DSU/CSU self test, loopbacks, DSU/CSU reset, alarm counters, and T1 statistics)
• Offers simplified SNMP management, with router and DSU/CSU managed as a single SNMP entity through CiscoWorks/CiscoView. The Cisco T1 DSU/CSU WIC SNMP agent supports the standard MIB II, Cisco integrated DSU/CSU MIB, and T1 MIB (RFC 1406). All T1 performance statistics can be monitored. The router also generates the appropriate SNMP traps in response to DSU/CSU alarms.
• An end-user-initiated manual loopback button allows users at remote sites to easily initiate a T1 network line loopback by pushing a recessed button on the WIC front panel without having to access the router via a console port or Telnet.
• Provides LEDs for carrier detect, loopback, and alarm, allowing for quick troubleshooting.
• Physical convenience-No additional space is needed because the Cisco T1 DSU/CSU WIC is inserted into the router. This integrated solution eliminates the need for a separate serial cable, reducing deployment time and cost.
• High reliability-The integrated DSU/CSU reduces the number of components in the network, leading to higher reliability. The serial cable that connects a router serial port to an external DSU/CSU is eliminated. The integrated DSU/CSU is powered from the router, eliminating the power supply for an external DSU/CSU. The Cisco 2600XM, 3600, and 3700 series are all available with redundant power systems, which cover the integrated DSU/CSU.
Flexibility and Investment Protection
The Cisco T1 DSU/CSU WIC extends the Cisco commitment to providing customers with maximum flexibility and investment protection through modular WICs that are supported on award-winning router platforms. When WAN bandwidth requirements or service provider pricing change, users can easily change WAN services either by changing the software configuration or replacing the WIC. Because the same card can be used on Cisco 1700, 2600XM, and 3700 series router platforms, the number of stocking units can be reduced, and the WIC can be redeployed from one platform to another.
Because the DSU/CSU plays an equally critical role as the router in helping to ensure WAN connectivity, many customers feel that it is important to have a support contract for both. Support for the integrated DSU/CSU is included in the maintenance contract for the Cisco router at no extra charge. However, if the router and DSU/CSU are from different vendors, it can be inconvenient to manage support contracts from multiple vendors. Further, when you need service and support, it is difficult to pinpoint a problem when phone calls have to be made to different vendors.
Cisco provides single-vendor support for its routers, integrated DSU/CSUs, and other network equipment. With its dedication to reliable support and customer satisfaction, Cisco offers numerous support programs to meet your business needs, including onsite support. A single phone call to a single vendor-Cisco takes full ownership of support when needed.
An integrated solution has fewer components; hence, fewer points of failure (for example, one less power supply and fewer cables). This leads to enhanced reliability.
Consistency with WIC-1DSU-T1
The Cisco T1 DSU/CSU WIC offers all of the features of the WIC-1DSU-T1 and can be smoothly deployed without requiring any additional learning.
