This even includes calls back to a BT number

as the previous holder of the range, then the CP
routes the call to BT. BT is paid the £ROLO for
an applicable service as in Part 1.06, but BT pays
the CP an Additional Porting Conveyance charge

out in delivering the call to BT.

not get involved in the establishment of the CP to CP charge.

Element Based Charging (EBC)
used within both BT Basic and BT Transit Telephony
Element Based Charging uses switch related elements for charging.
This allows BT to recover costs based upon the amount of ‘work’ done within
our network when carrying a call, depending on how much switching and how
far (in some cases) we carry the call before delivery.
This method of charging is applicable for services such as BT Basic Telephony
Part 1.01, and BT Transit to CP Telephony Part 1.12.
As part of BT’s Least Cost Routing ‘Pricing Promise’, the actual route of each call
is not considered, but the ‘shortest path’ method is used. Using this method, all possible
call routes are considered (even backup circuits and private links) when evaluating
the ‘shortest path’, so that a CP is never over-charged for a call by this method,
even when those circuits will never be used for those types of telephony.
The customer is always charged based upon the theoretical least cost (shortest) route !
The EBC bands are described in the following slides...
