1 Forecasting Of Interconnection Traffic, Interconnect Links and SS7 Signalling Links Requirements
1.1 Forecast Requirements
1.1.1 stc requires Other Licensed Operators using stc's Interconnection services to provide forecasts between the Other Licensed Operator's and stc's Networks, in good faith and as accurately as is reasonably possible, of the following:
- Traffic route capacity for routes from the Other Licensed Operator to stc
- Interconnect Link capacity for links carrying the above mentioned traffic routes
• Signalling capacity requirements.
1.1.2 The following high level forecasting steps will be adopted:
• Other Licensed Operator submits initial forecast
• Joint Technical Review Committee agree forecast
• Forecast becomes Advanced Capacity Order (ACO)
- ACO sets commitment levels for Calendar Months one (1) to twelve (12)
• Other Licensed Operator places firm orders against ACO
• Firm orders monitored against ACO
• Reforecast submitted every six (6) Calendar Months
• ACO extended by further six (6) Calendar Months

The Other Licensed Operator, in accordance with the template provided in this Annex E - Attachment 1 (New Route Forecasting Form), shall update these forecasts every six (6) Calendar Months.
1.1.5 The Other Licensed Operator shall provide to stc forecasts for Interconnect Link capacity in terms of STM-1/STM-4 circuits required every six (6) Calendar Months on 1 December and 1 June of each year in the format shown in this Annex E, Attachment 2 (Interconnect Link Forecasting Form). This shall be monthly forecasts for months one (1) to twelve (12) and quarterly forecasts for months thirteen (13) to twenty four (24).
1.1.6 The Other Licensed Operator shall provide to stc forecasts for network traffic in terms of busy hour erlangs required every six (6) Calendar Months on 1 December and 1 June of each year in the format shown in Annex E, Attachment 3 (Network Capacity Forecasting Form).

The Other Licensed Operator shall update these forecasts every six (6) Calendar Months.
1.1.7 The Other Licensed Operator shall provide to stc forecasts for any special or predicted network traffic variations (e.g. unusual or peak demands) as early as possible, but not less than six (6) Calendar Months before any such occurrence, if it is expected that traffic will deviate from normal patterns.

1.2 Advanced Capacity Order (ACO) Forecasting Restrictions
1.2.1 The Other Licensed Operator shall update the Advanced Capacity Orders (ACO) on 1 December and 1 June of each year by submitting the ACO forms, as per Attachments 1, 2 and 3 to this Annex E, to the stc commercial account manager.
1.2.2 Increases in capacity orders for the next forecast period shall be subject to availability of equipment and resources. stc can offer no guarantees that such increases in ACOs can be satisfied. stc however accepts the capacity orders increase up to 25% deviation from the provided forecast.
1.2.3 Decreases in capacity orders for the next forecast period shall be accepted subject to reasonable charges being levied by stc on the Other Licensed Operator for any costs reasonably and necessarily incurred as a result of planning for and potentially purchasing relevant equipment that cannot be reasonably used elsewhere in the stc network. However, stc accepts the capacity orders decrease up to 25% without levying any additional charges as penalty.
1.2.4 Figure 1 below shall result in pre-payment of connection charges as specified in Annex F (Price List) being paid by the Other Licensed Operator up to the value of the minimum tolerance ACO. This payment will be treated as a pre-payment for future capacity orders placed for Interconnect Links to the same stc Interconnect Node within the next twelve (12) Calendar Months.

1.3.2 In the event that the traffic, capacity and route forecasting processes have failed to maintain the target Unsuccessful Call Termination Ratio, stc and the Other Licensed Operator shall agree to work together in good faith to resolve congestion issues by planning, as necessary, further Interconnection capacity or new traffic routing plans in an expedient manner and permit the free flow of traffic between the networks according to the target Unsuccessful Call Termination Ratio. Either Licensee shall have the right to call a meeting of the Joint Technical Review Committee as detailed in Annex D (Management of Interconnection) to progress resolution of congestions.
1.4 Planning of New Points of Interconnection
1.4.1 Prior to making Interconnection available on new or previously not interconnected switching facilities, stc or the Other Licensed Operator, whichever is the equipment owner, shall have completed all commissioning and testing activities in accordance with the recommendations of the switch vendor and industry best practice, including but not limited to inter-working testing within its own network, and activated the SS7 Point Code. (See Annex H (Operations and Maintenance Manual).
1.4.2 Forecasts for new routes should be submitted using the form in Attachment 1 (New Route Forecasting Form) of this Annex E.
