2.0 PRODUCT OVERVIEW

Overview:

CENTURYLINK has developed a new High Speed Internet offering to remain competitive in the market

place. In September 2009, Business sales channels began offering 15/1.5 Mb, 20/2 Mb, 25/2 Mb product

to all classes of business customers. In order to deliver the higher speeds, CenturyLink introduced a new

DSL technology: ADSL2+ Bonded. ADSL2+ Bonded HSI service consists of installing two ADSL2+ lines

to the customer’s premise, and then through special software/configuration within the DSLAM and

modem/gateway, the individual DSL lines are combined to perform as one. Both lines are prefielded prior

to installation to ensure pristine lines. The technology allows for higher speed offerings while maintaining

a reasonable customer serving area (up to 10kft from serving device). ADSL2+ Bonded HSI is only

available out of DSL devices that have Ethernet feeding the device’s transport.

Effective December 21st, 2009, CenturyLink expanded its sales footprint of ADSL2+ Bonded HSI service

to include Residential (COS 11) Customers. The residential product offering consists of a single “up-to”

25Mb price-point. However, for loop stability and support reasons, each residential customer will be

qualified and provisioned at one of the following speed profiles: 15/1.5 Mb, 20/2 Mb, 25/2 Mb (NOTE:

these are the exact same profiles as our Business offering). From an installation and troubleshooting

perspective there is no difference between residential and business customers.

 S&E codes are the same across both Business and Residential

 Installation of a Cisco DDR2200 Gateway is required for both Business and Residential

 The minimum acceptable throughput policy is 80% or greater of the quoted speed (15/1.5 Mb,

20/2 Mb, 25/2 Mb) for both Business and Residential

The ADSL2+ Bonded offering is available in Ethernet transport grade DSLAMs where the DSLAM is

capable of supporting the bonded technology. At this time those sites are limited to customer serving

areas supported by the following DSLAMs:

CALIX E5-11x ADTRAN TA1x48A with 1x00F Ethernet Uplink (coming soon)

CALIX C7 TELLABS UMC-1000 (coming soon)

ADTRAN TA5000

ADTRAN TA1x48 with 1x00F Ethernet Uplink

All ADSL2+ Bonded orders are supported as full installs and tested with the JDSU HST-3000 test set via

an automated D.A.T.A. test script. This test script has been built specifically to test ADSL2+ Bonded

HSI speed offerings.
