3 The Modem remains locked to the CMTS,responding to SNMP, enabling subscribers to resumeactivity quickly when toggled again. The buttonserves as a security feature, assuring the customerthat the PC-network connection is de-activated whenthe button is in the off position, alleviating securityconcerns of an always on TechnologyThis advanced transport technology (DynamicPayload Header Suppression) provides the sub-scriber with faster data transfers. It also allows opera-tors to increase the number of subscribers on theirnetwork without affecting subscriber connectionspeeds. Under typical network conditions, both thesubscribers and operators can benefit from moredata bandwidth per customer, and of more voicechannels for s latest DOCSIS certified Cable Modem , the DCM425 incorpo-rates the latest generation of silicon.

4 The DCM425 supports up to 16upstream flows and improved data throughputrates. It represents a significant improvement of our DOCSIS product-line in a small form 16 upstream flows allow operators to provide tiered data servicesand support more efficient traffic prioritization schemes for advancedservices. The DCM425 allows symmetrical data transfer, and tripledupstream throughput. The Modem also integrates Propane technology, enabling the con-nection of more Internet users without additional network s case design is consistent throughout its product line of cablemodems and gateways.
