Quarterly web-call – Voice strategy – ISDN

ISDN strategy: • ISDN will continue to be supported on 21CN In addition ….

Voice strategy – Wholesale Broadband Connect Converged (WBCC)

What does it do?

What are the benefits?

Offers CPs a packaged end-to-end converged voice and broadband service Allows CPs to differentiate in broadband / voice features, overlay and integrate next generation SIP based applications, and call packages Allows CPs to offer Broadband services Will also be offered in a voice-only form, Wholesale Voice Connect (WVC) Provides Narrowband service to allow CPs to supply Publicly Available Telephone Service (PATS) services via their call servers Voluntary migration to WBCC starts in January 2010 in specific geographies.

National

migration to WBCC starts from end April 2010 following WLR migrations to 21CN 11

Voice strategy – Wholesale Voice Connect (WVC)

What does it do?

The voice only variant of WBCC that will offer CPs an alternative to Wholesale Line Rental (WLR) plus Wholesale Calls / Carrier Pre Select (CPS) Allows the voice service to be defined and delivered by CP’s owned or managed network What are the benefits?

An alternative to WLR allowing the CP’s call server to deliver the voice service Gives the ability to innovate, differentiate and segment through voice services that do not directly rely on a BT owned feature set or capability Gives the ability to leverage call server capability and offer narrowband and broadband derived voice services Benefits from synergies, a common infrastructure/system interfaces and product family components (where a CP is also offering WBCC (voice and broadband) to its end users, either in the same or different geographies) 12
