the software configuration or replacing the WIC. Because the same card can be used on Cisco 1700, 2600XM, and
3700 series routerplatforms, the number of stocking units can be reduced,and the WIC can be redeployed fromone
platform to another.
Single-Vendor Support
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.
Enhanced Reliability
An integrated solution has fewer components; hence, fewer points offailure (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.No
