1 CHP Max FORWARD PATH TRANSMITTERS CHP Max5000 Converged Headend Platform Unlock narrowcast bandwidth for provision of advanced services Economical and full-featured versions Low profile footprint allows 200 transmitters in a standard rack Simplified installation and management Universal management through Craft interface and SNMP with HMS CHP Max5000 Forward Path Transmitters help MSOs unlock narrowcast bandwidth as subscribers demand advanced services and new content. By dedicating one low power transmitter to each node, CHP Max5000 helps to nearly quadruple system bandwidth capacity. CHP Max5000 transmitters are available in two versions an economical single-input model and a full-featured dual-input model. Both versions offer hot-swapping and integrated management through the local Craft GUI and remote management via SNMP HMS-compliant interface for external connection to an element manager. Energy efficient internal components and effective thermal design keep lasers cool to ensure for effective, reliable performance. The full featured, dual-input transmitter offers multiple levels of drive control providing maximum flexibility addressing a broad range of applications. The dual-input capability presents 60 db of isolation, much superior to alternative offerings. The dual-input forward transmitter's high performance isolation offers, for example, simultaneous advanced service deployment of video and telephony without cross-talk impairments. Integral high isolation eliminates having to add external devices to achieve similar performance, thereby lowering capital expenditures and reducing complexity. Up to 10 CHP Max5000 transmitters can reside in the standard 2RU CHP Max5000 chassis, with RF input and optical bulkhead connector access on the rear panel. Thus, a standard 40RU rack holds up to 200 CHP Max5000 transmitters, providing exceptional space efficiency and reducing operational costs. Access and Transport

3 CHP Max Applications Unlocking Narrowcast Bandwidth Enables MSOs to increase the base of customers for advanced services Accelerates scaled deployment of video-on-demand, high-speed internet access, and voice-over-ip Lowers cost of bandwidth per subscriber Baseline HFC Configuration Segmented Forward Path In a typical hybrid fiber coaxial network, one high power narrowcast transmitter may feed as many as four nodes, which together can serve nearly 2,000 subscribers. Total Homes Passed: 20,000 Homes Passed/Node: 500 Nodes Required: 40 Narrowcast Group Size: 2,000 (4 nodes) Number of Narrowcast Groups: 10 Broadcast Bandwidth: 293Mbps Narrowcast Bandwidth: 1254 x 10 = 12,540Mbps Total Bandwidth: 12,833Mbps Summary You can segment the forward path to provide more narrowcast bandwidth for advanced services by using one CHP Max5000 low power forward transmitter for each node, reducing the number of subscribers served by each transmitter to one quarter of those served before segmentation. This reduction increases bandwidth per subscriber by nearly 400%. Total Homes Passed: 20,000 Homes Passed/Node: 500 Nodes Required: 40 Narrowcast Group Size: 500 (1 node) Number of Narrowcast Groups: 40 Broadcast Bandwidth: 293Mbps Narrowcast Bandwidth: 1254 x 40 = 50,160Mbps Total Bandwidth: 50,453Mbps Narrowcast group size decreases from 2,000 to 500, producing a fourfold improvement in bandwidth and contention. System capacity grows by nearly 300%. Cost of bandwidth decreases up to 3.7 times. 3
