8. Overtime installation surcharge is calculated in accordance with the Company's tariff on surcharge for work undertaken outside normal operating hours.

9. Calculation of CBR Usage Charge:

PEAK_CBR =

[Peak CBR usage minutes exceeding the respective basic monthly usage]*5.15 ￠

OFFPEAK_CBR =

[Off-peak CBR usage minutes exceeding the respective basic monthly usage]*4.15 ￠

Total CBR Usage Charge = PEAK_CBR + OFFPEAK_CBR

10. Calculation of UBR Usage Charge:

10.1

For SVC mode of operation:

10.1.1

Each standard ATM cell is 53 bytes long and contains 48 bytes payload.

10.1.2

For each UBR SVC session, the minimum chargeable cell quantity is 50K cells per minute. If the actual ATM cell transfer for a UBR SVC session during the peak and off-peak period are lower than the cell quantity of (usage duration of the UBR SVC session in minutes during the respective peak and off-peak period * 50/1000 M cells), the latter will be used in calculating the respective chargeable peak and off-peak UBR usage for that UBR SVC session.

PEAK_UBR =

[Peak UBR M cells exceeding the respective basic monthly usage]*19.62 ￠

OFFPEAK_UBR =

[Off-peak UBR M cells exceeding the respective basic monthly usage]*15.75 ￠

Total UBR Usage Charge = PEAK_UBR + OFFPEAK_UBR

10.2

For PPP/PVC mode of operation:

10.2.1

Each standard ATM cell is 53 bytes long and contains 48 bytes payload for PPP/PVC communication session.

10.2.2

If the actual data transfer for a UBR PPP/PVC session during the peak or off peak period are lower than the byte quantity of (usage duration of the UBR PPP/PVC session in minutes during the respective peak and off-peak period * 2.4 M bytes), the latter will be used in calculating the respective chargeable peak and off-peak UBR usage for that UBR PPP/PVC session.

PEAK_UBR =

[Peak UBR M bytes exceeding the respective basic monthly usage]* 0.409 ￠

OFFPEAK_UBR=

[Off-peak UBR M bytes exceeding the respective basic monthly usage]* 0.329 ￠

Total UBR Usage Charge = PEAK_UBR + OFFPEAK_UBR
