UK(a) - supports non-CCITT version of charging information, as follows:

national options marker

segment count

duration information

UK(b) - charging information not supported.

UKa support

At release 4 UKa will support both CCITT and UKa charging info

UKa do not support monetary unit or distance

Supports one tariff period only. Support of more than one tariff period is not possible because no mechanism exists for setting the time of day clock in the TP4/II

&UKb& = yUKb support

X.25: No - planned for future release

- Charging Information ... continued

ONA compatibility

RD 0004 part 8:1.C (PICS proforma Public Network1984)

FS8 - Charging Information - requesting service ... O = Optional

FR8a - Charging Information - monetary unit......... O = Optional

FR8b - Charging Information - segment count......... O = Optional

FR8c - Charging Information - call duration......... O = Optional

I dont think release 4 supports monetary unit - need to check this

Test plan and implementation issues
