Study Notes
Point of Interconnection (POI)
- The POI is the point at which the GMSC of a fully mobile network and the gateway switch of BSNL or local/tandem/TAX exchange of the basic service network are interconnected.
- The POI should be commissioned within 30 days from the date of application submission, excluding time taken by the interconnection seeker for completing concerned activities.
Augmentation of POI
- Traffic measurements are taken by BSNL and private operators during the agreed route busy hour for seven days on a quarterly basis.
- The number of junctions is calculated as per Erlang Table for the Grade of Service (0.005) as per the interconnection agreement, including 25% additional junctions for future traffic requirements.
- The POI capacity should be reviewed regularly, and the number of E1s may be reduced if not justified as per traffic requirement.
Provisioning of POI
- The Circle office handles applications submitted by various operators for POI and issues demand notes/advice notes.
- The SSA Heads should speed up the process of feasibility reports, and the nodal officer for POI should review pending feasibility reports regularly.
- Once payment is made, the advice note should be issued immediately, and POI should be commissioned with live traffic within 12 months.
Reasons for Delay in POI Provisioning
- Delay in issuing demand notes due to non-receipt of feasibility reports from SSAs.
- Delay in nomination/declaration of a local exchange as SDCC tandem for providing connectivity to NLDOs/BSOs.
- Delay in provision of infrastructure and power after payment of demand note.
- Delay in constitution of a testing team or nomination of a representative on behalf of BSNL for acceptance testing.
Approval of A/T Report by Circle Office
- The Circle office should maintain a database of spare capacity of E1 ports available in switches designated for POI.
- Efforts should be made to observe a time limit of 3-5 days for completing infrastructure and necessary power requirements.
- A tandem exchange should be designated in each SDCC well in advance for providing connectivity to NLDOs/BSOs.
- The testing team for each SSA should be nominated in advance to save time.
