Motorola Summary
Subscriber Bandwidth Escalation Continues
•
•
Voice, Video, Gaming and Data Services
are Driving new and higher bandwidth
Requirements
– Customers are requiring greater
Capacity
– Competition is Fierce
• DSL is providing much higher
bandwidth – ex. 50 Mbps with
VDSL/ADSL2
• Some Telco’s deploying higher
bandwidth via Fiber-to-theHome/Curb
• Satellite going to 1000+ Channels
– Some Customers are even requiring
more Bandwidth then a single
Downstream or Upstream can deliver;
higher rate limits
Cable Operators need a Higher
Bandwidth Downstream & Upstream
Solution!
DOCSIS Evolution: Higher Bandwidth with
each Successive Version
DOCSIS 1.0/1.1:
•
Higher Upstream (US) and Downstream (DS) Speeds &
Greater Density lead to additional services & Lower
Subscribers per DS/US
DOCSIS 2.0:
•
•
Additional Bandwidth in US Only: ATDMA, SCDMA, Logical
Channels
Ingress Noise Cancellation created Additional Bandwidth in
US only
DOCSIS 3.0:
•
Bonding together Downstream & Upstream Channels to
create higher bandwidth Logical Channels
• Draft Specification within CableLabs® Standards
Group
• Downstream definition happening with M-CMTS Edge
QAM effort
• Downstream works with some existing CMTS
Hardware
• Requires new CM Hardware
Higher Bandwidth via Channel Bonding
• Increasing Bandwidth by transmitting DOCSIS frames
across multiple RF Channels
• Standards effort for both Upstream (US) and
Downstream (DS) direction
• Standard will logically bond together some number of
US or DS RF Channels and then multiplex packet
transmission over those RF channels

M-CMTS Goals
• “Independent scalability of CMTS functions from DS PHY”
– Means: need to add DS channels without adding US channels
• “Lower the cost to deliver video over DOCSIS service to be
competitive with today’s MPEG VOD”
– 2005 Incremental DOCSIS DS channel cost: $24K ASP for
2DS+8US CMTS blade = $12, 000 per DS channel
– 2005 Incremental MPEG VOD channel cost: $12K for 24-channel
MPEG EQAM = $500 per DS channel
• But with no rate limiting, scheduling, QOS, encryption, VOIP
compression, or RF switching
What’s important and not for M-CMTS
• What’s important is that the two M-CMTS goals be met:
– De-coupling downstream and upstream capacity; and
– Lowering the cost of downstream capacity.
• What’s important is the adoption of the DEPI specification
by the EQAM industry.
– Enables a transition to DOCSIS IPTV with DEPI EQAMs.
• What’s NOT important is the concept of separating the
upstream PHY layer:
– Separation into an “upstream shelf” and definition of an “Upstream
Edge Physical Interface” (UEPI)
– Independent vendor implementations of “CMTS Core” and
“upstream shelf” MAC functions
