3. 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

4. New Revenue Opportunity for Operators
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

5. 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
