Voice Services:  Questions an MSO Must Ask
--------------------------------------------------------------------------------

     -  Should an MSO offer voice services?

     -  If the MSO offers voice, what is the scope --
        Full-service primary line or limited second-line only
        service?

     -  How should the MSO offer voice services --
        What is the timing?  What is the technology?


33 -------------------------------------------------- [AT&T logo] AT&T Broadband



Voice Services:  Smart Play for Cable Operators
--------------------------------------------------------------------------------


-    Significant revenue and margin opportunity
     -    Market size in excess of $100 billion annually
     -    Market almost entirely served by the RBOCs

-    Significant contribution to financial growth

-    Optimizes core broadband network

-    Improves performance of all broadband products
     -    Voice customers pull through other broadband products
          -    56% own 2 products
          -    24% own 3 products
     -    Product bundles including voice reduce video churn between 10%
          and 22%

-    Positions us strategically to compete against the RBOCs


34 -------------------------------------------------- [AT&T logo] AT&T Broadband





Voice Services:  Primary Line vs. Second Line Telephony
--------------------------------------------------------------------------------


-    Primary Line play creates maximum market opportunity
     -    5 - 10x greater voice revenue per customer
     -    7 - 8x greater cash flow per customer
     -    Less than 10% additional upgrade and rebuild capital required

-    Provides foundation for long-term competitive position
     -    Counters RBOC data and full service voice DSL play

-    Operationally no more difficult than second line service


35 -------------------------------------------------- [AT&T logo] AT&T Broadband





Voice Services:  Circuit Switched Today is Better Than Waiting
--------------------------------------------------------------------------------


-    Ability to obtain market share is greater today, before RBOCs bundle
     their voice and DSL products

-    Voice over IP requires the same operational expertise as
     circuit switched
     -    Both require significant learning curve - starting early is critical
     -    Voice over IP synergy with Data operations expected to yield 5+%
          savings in operating expense

-    Flexible migration to Voice over IP minimizes stranded capital risk


--------------------------------------------------------------------------------
       Voice over IP expected to be available in 2003, and AT&T Broadband
            has easy migration path to adopt when readily scaleable
--------------------------------------------------------------------------------

Voice Services:  Circuit Switched Today is Better Than Waiting
