Cisco Systems WIC-1DSU-T1-V2 manual Single-Vendor Support, Enhanced Reliability

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 ne eded.

Enhanced Reliability

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.
