Hi Rey,
SMARtnet covers traditional Cisco products (enterprise products ie. ISR routers), Small Business Support Center covers the small business line.
In the UC group of products, for some reason, Cisco considers the UC520, AP521, and WLC526 which are branded small business to be traditional Cisco products and are covered under SMARTnet. But, the UC540 and UC560 are covered by SBSC. One major difference in the UC arena is the support for CLI vs CCA config.
However, I noticed your post was in the Small Business - switches category. If you have a small business switch those are covered by SBSC not TAC. SBSC will support the CLI and web gui config of the small business switches, where CLI is applicable to the model.
SBSC contracts tend to be for 3 year periods and can be significantly less expensive than SMARTnet agreements.
Hope that helps.
Best,
David
