DOCSIS Evolution & Road Map
DOCSIS 1.0 (Global Standard)
– 15 million products shipped worldwide as of YE2001
– Modem price has declined from $300 in 1998 to $50 in 2002
– 214 CM Certified, 28 CMTS Qualified
DOCSIS 1.1 (Tiered services, VoIP)
–
–
–
–
–
–
Interoperable and backwards-compatible with DOCSIS 1.0
“Quality of Service” and dynamic services, a MUST for PacketCable
Increased Security: authentication and secure software downloading
Account Management for usage and event-based billing
CCCM – lowest cost yet (less than $50)
32 CM Certified, 16 CMTS Qualified
DOCSIS 2.0 (Symmetric Services)
–
–
–
–
Greater (x6) upstream capacity of DOCSIS 1.0
Greater (x3) upstream capacity of DOCSIS 1.1
Greater Bandwidth efficiency b/s/Hz
Improved robustness against interference

DOCSIS 1.1 Overview
• Interoperable with DOCSIS 1.0, plus more…
– Access to bandwidth at high data rates or lower latency
adds more value
• Enhanced “Quality of Service” (QoS)
– Guarantees and/or limits for data rates
– Guarantees for latency
• Improved security - designed to reduce possibility
of “theft of service, provide secure software
downloading.”
• Interoperability - DOCSIS 1.0 and DOCSIS 1.1 cable
modems and CMTSs on the same plant. Better
operation and OSS features
• Transmit Equalization - more robust transmission
New Revenue Opportunity for Operators

DOCSIS 2.0 Overview
(100% backward compatible with DOCSIS 1.0/1.1)
• Symmetrical services are enabled by DOCSIS 2.0
– 1.5x greater efficiency
• operates at 64 QAM
– 2x wider channels
• new 6.4 MHz wide channel
• DOCSIS 2.0 widens the pipe for IP traffic, allowing cable
providers to create more and better services for voice,
video, and data
• It does this by using enhanced modulation and improved
error correction
• Superior ingress and impulse noise performance
3 Times better upstream performance than DOCSIS 1.1
6 Times better upstream performance than DOCSIS 1.0
