Edge QAM Overview
Chris Brown,
Sr. Product Manager, Motorola, Inc.
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!

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

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
