Introduction to WBCC


End user driven requirements

“Why do I have another number for my broadband phone?”

“I don’t know which phone to use to get the best calls costs!”

“When I call a friend on his mobile from my broadband phone he does not know it is me calling!”

“Why don’t I have the same terms and conditions on my broadband and old telephone service?”

“I want control of the features I get from my provider!”

Allows CPs to differentiate and innovate via next generation applications by exploiting SIP

Improved end user experience

‘On net’ and ‘off net’ service communality

Lower total cost of ownership

WBCC key Benefits


Overview of WBCC

• BTW provides a single access voice and broadband product to CP• CP offers both voice and broadband based services to end user• Broadband component is as per WBC functionality• Baseband service will allow CPs to supply 21CN PATS services

Access Gateway Control – Separate

from PSTN Call Server. Maps H.248 to SIP-UNI messages to enable a remote Call Sever to

control End Users lines

Session Border Controller. Provides limited call control functionality inc. the ability

to cut CDRs and Media functionality, e.g. Codecs.

Voice EP

WBCC Product Model


Voice Extension Path - What is an EP?

•A voice EP routes voice traffic from SBC located in a POSI to the MSIL

•CP can have multiple Voice EPs connected to the MSIL

•Configuration of two separate VLANs for

- Voice Media (10 to 800 Mbps)

- Voice Signalling (1 to 50 Mbps)

•Logical Connection CCC will be used for managing signalling and media VLANs


Voice EP: Scenarios designed so far– Support via eportal for Day 1 only

Voice EP provide

• Allows the CP to place a voice EP provide order

• BTW will validate bandwidth ordered against the available MSIL bandwidth

• CAC will be configured on SBC

Cancel Voice EP provide

• CPs can cancel Voice EP provide up to Point of No Return

• PONR is established as part of Voice EP provide (will be before activate)

Voice EP cease

• CP can cease Voice EP

• Voice EP cease order will be rejected if it is being used by Voice Route


•The Voice Route product enables CPs to configure preferred domain name and private ID that are later used for end user provisions within serving exchange

•The CP has to place different service Voice Route orders for each combination of domain name + private ID + Serving exchange

•Voice Route mandates CPs to specify primary and secondary voice EPs to be used

•CPs need to order Voice EPs before placing orders for Voice Route

Voice Route – What is it?


Integrated Voice End User Access – What is it?

•IVEUA is the WBCC end user product

•This is combined voice and broadband service provided on same access consumed from Openreach

•Voice call control is managed by CP’s call/apps server(s)

•Supports broadband service as per WBC

•Involves configuration of AGCF for delivering voice media and signalling to CP

WBCC - Assurance


WBCC Test and Diagnostics - Proposed capabilities

Delivery April 08

•MPF Copper Line Test (EMP800 Service)

Prototypes today available for trial

•Linecard test – presence and function of MSAN linecard

•Basic dial tone test - presence & function of dial tone, BAU routing

•Jumper test - presence of jumper

•Parametric line test including termination detection

•Basic voice call test – using BAU routing


Prototypes being considered for development in Day 2 & 3

•Enhanced dial tone test - presence and function of dial tone using “Test CP” routing

•Directory number test – validation of line number

•Enhanced voice call test - using a “Test CP” routing

•Presentation of call performance info from network

•Presentation of call trace info from network

•Alarm and event analysis
