Procera Networks announced it has received an ".. initial order from a top five North American DSL operator. The carrier selected Procera’s Intelligent Policy Enforcement systems to support detailed subscriber-aware traffic analysis and reporting across its fixed-line broadband network and for sophisticated network and subscriber analytics across its deployment footprint. Procera recognized revenue from this initial order in the fourth quarter of 2012".
Note that Procera had two 10% customers in Q4, totaling to 23% (here) - so no single customer was above 13% of the quarterly revenues ($16.6M) - $2.16M.
