Goodwill [Abstract]
GOODWILL	3. GOODWILL For purposes of valuing our goodwill, we have the following reporting units: IP products, IP services, data center products and data center services. We performed our annual impairment review as of August 1, 2014 and concluded that goodwill attributed to each of our reporting units was not impaired as the fair value of each reporting unit exceeded the carrying value, including goodwill. To determine the fair value of our reporting units, we utilize the discounted cash flow and market methods. We have consistently utilized both methods in our goodwill impairment tests and weight both results equally because we believe both, in conjunction with each other, provide a reasonable estimate of the fair value of the reporting unit. The discounted cash flow method is specific to our anticipated future results of the reporting unit, while the market method is based on our market sector including our competitors. We determined the assumptions supporting the discounted cash flow method, including the discount rate, using our best estimates as of the date of the impairment review. To determine the reasonableness of these assumptions, we performed various sensitivity analyses on certain of the assumptions used in the discounted cash flow method, such as forecasted revenues and discount rate. We used reasonable judgment in developing our estimates and assumptions and there was no impairment indicated in our testing. The assumptions, inputs and judgments used in performing the valuation analysis are inherently subjective and reflect estimates based on known facts and circumstances at the time we perform the valuation. These estimates and assumptions primarily include, but are not limited to, discount rates; terminal growth rates; projected revenues and costs; earnings before interest, taxes, depreciation and amortization for expected cash flows; market comparables and capital expenditure forecasts. The use of different assumptions, inputs and judgments, or changes in circumstances, could materially affect the results of the valuation. Due to inherent uncertainty involved in making these estimates, actual results could differ from our estimates and could result in additional non-cash impairment charges in the future.

For purposes of valuing our goodwill, we have the following reporting units: IP products, IP services, data center products and data center services. We performed our annual impairment review as of August 1, 2014 and concluded that goodwill attributed to each of our reporting units was not impaired as the fair value of each reporting unit exceeded the carrying value, including goodwill.

To determine the fair value of our reporting units, we utilize the discounted cash flow and market methods. We have consistently utilized both methods in our goodwill impairment tests and weight both results equally because we believe both, in conjunction with each other, provide a reasonable estimate of the fair value of the reporting unit. The discounted cash flow method is specific to our anticipated future results of the reporting unit, while the market method is based on our market sector including our competitors.

To determine the reasonableness of these assumptions, we performed various sensitivity analyses on certain of the assumptions used in the discounted cash flow method, such as forecasted revenues and discount rate. We used reasonable judgment in developing our estimates and assumptions and there was no impairment indicated in our testing.
