EQAM’s and Bandwidth What is the relationship?
• MSO’s need more bandwidth to offer more content– Offer more HD– Offer more VOD/on-demand– Offer more high speed data (Internet Access)
• BW Reclamation and Expansion– Use SDV to reclaim BW– Digital Simulcast, DTA, and the transition to all digital– Create new BW: expand to 1 GHz plants
• When more BW is available:– What to do? Add more QAM channels– How to do it? Install more EQAM devices!

• Deliver Narrowcast Content
• GigE to QAM/RF
• Deliver digital video and audio– VOD and SDV– Broadcast Video
• Deliver high speed data– M-CMTS– DOCSIS 3.0 channel bonding
• Competition– Functionality and reliability– Density– Price/QAM

Narrowcast Bandwidth Trends
• Tuners (STB’s) per downstream service group are decreasing
• QAM channels per downstream service group are increasing
• QAM channels per EQAM RF port are increasing (density)
• $$/QAM channel is decreasing
• Capacity for simultaneous usage is increasing– Approaching Switched Unicast Model!

End Game: Switched Unicast Dedicated BW per Subscriber!
• Switched Unicast allow for 100% simultaneous usage
• Each subscriber has their own digital channel– Tuning happens in the headend
• Each subscriber is individually accessible– Accessibility of an IPTV system
• Huge opportunity for highly targeted advertising– Send relevant custom advertisements to individual subscribers

REM1000 Redundancy Switch• REM 1000 Overview
– Used to protect against APEX module failure– Eliminate need to re-wire RF if APEX module fails– Switch has 12 RF inputs and 10 RF outputs– Two APEX1000 units per each REM1000 switch– APEX optional redundancy configuration
• Each APEX can provide up to 5 RF outputs (up to 40 QAM)• One RF output is redundant
• REM1000 Requirements– Bi-directional communication with APEX units– 3 Ethernet ports (allow point to point connections, APEX to switch)– Fail in passive manor so not single point of failure
