What is DSL

How DSL works

What are the issues in working with DSL Where are the business opportunities

DSL1-4

DSL in the World

DSL is growing

World Wide DSL reached 115 Million lines by Sep2005 (DSLF)

World Wide DSL growing to 500 Million lines by 2010

Leading deployments: Korea, Taiwan, Hong Kong, Japan,

Changes making it easier to install DSL

DSL was slow initially due to ATM backbone complexity

DSL Forum focused on auto-configuration, interoperability

DSL has in the last year greatly reduced truck rolls to the pointwhere we now have 95% self install

ADSL CPE is standards based with lower cost equipment withmany options including wireless networking resulting inincreased take rate

DSL1-5

Market Trends (Faster + Value Add)

Faster Higher speeds standards (ADSL2+ and VDSL2)

Better spectrum management (RE-ADSL part of ADSL2, ADSL2+)

SHDSL (Single Pair High Speed DSL)

Bonded Services (2, 3, 4-pairs of ADSL or SHDSL)

IP/Ethernet versus ATM transport

Value Added Services

Application Service Provider (ASP)

Remote Backup (Internet Disk Drives to Managed Services)

Videoconferencing (voice / data / video)

Voice over IP (VoIP) i.e. BroadVoice, Vonage, Skype,

Video over IP, Video on Demand (VOD), 2-way TV

Security monitoring (DOS attacks) and Virus Scanning Services IP VPN (Internet Protocol Virtual Private Network)

Secure, encrypted (AES, DES3), authenticated with certificates

Microfilter

ANSI T1E1.4 standard

http://www.pulseeng.com/

Example: DSL Rocket by Pulse

Also: Suttle, Excelsus, 2Wire, Corning/Siecor, Wilcom, Lea

Microfilter placed in front of each telephone

Microfilter gives clear voice quality, caller ID, call waiting

Microfilter allows for user self install of the DSL modem 70% self install being reported by several telcos

Separate pair for voice

2xRJ11 or 1xRJ14C

i.e. SDSL, SDSL2, IDSL

Watch for copper exhaustion

Line Sharing Pair (P3)

Voice and Data, wet loop

1xRJ11 i.e. ADSL, some SHDSL

FCC ruling for pair sharing

Naked DSL (P4) = data only, no POTS, dry loop

P1 P2 P3 P4
