General This section defines the system wise provisions and integration of the other Phases apart from Phase-I facilities.
Fibre Optic Communication Network Equipment.
The Fibre Optic Network extends thru all the Satellite Control Centres from 1 to 5. Under Phase-1 the FOCN will be connected from the Central Control Building TER to SCC 3 to SCC 4 to SCC 5 and back to TER as shown below.
FIGURE-1
Upon the implementation of the Phase-II the FOCN network will be from Central Control Building TER to SCC 1, SCC 2, SCC 3 to SCC 4 to SCC 5 and back to TER as shown below.
FIGURE-2 The SCC coming under Phase-II will be added to the network following the main running – back-up changeover scheme, and vice versa after FO changeover and equipment being inserted into the network. The Phase-II contractor will have to plan, manage and implement the migration and any hardware and software/programming required for the integration of the Phase-II equipment. Currently the Phase-I does not cover all the utility or buildings which are connected to SCC-3, SCC4 & SCC-5, so as and when these area will come the contractor for those area’s will have to plan,
Doc. No.: 2013-992-ETE-DBP-000-001 Title: TELECOMMUNICATION SYSTEMS-BASIS OF DESIGN
Rev: 00A Date: 21/02/12 Page: 35 of 36
manage & implement the upgrade of these above mentioned SCC’s with suitable Hardware and Software to commission the new areas. In addition to the above all the hardware and software/programming upgrade to be done at the CCB, Telecom Equipment has to be done by the contractor for that Phase or Area. For the BVS, Well Pads and Manifold connections the FOCN connectivity will be coming to the TER at CCB as designed in Phase-II, and then will be connected to the CORE SWITCH FOCN Equipment provided under Phase-I. The hardware to be added and software/programming to be implemented in the CORE SWITCH to provide the new connectivity to the BVS, Well Pads and Manifold to be done by the contractor for those areas. All the distribution and access network equipment, new or upgrade to be done by the Contractor providing communication network for the BVS, Manifold & Well Pads Area During the integration process of the PHASE-I and Phase-II networks requires rigorous programming, along with new hardware and upgrade to has to be done so as to form a complete single system. The contarctor providing the communication network for any other Phases than Phase-I will be responsible for this unification. The equipment’s in Phase-I and Phase-II should match in order to avoid any hardware and software integration issues. It will also be beneficial during to the maintenance stage to have the same type of equipment for Phase-I and Phase-II.
UHF Tetra Radio Equipment.
Under Phase-I scope the Tetra Radio system will cater to the CPF Area and Fresh Water Well System. But the system will be designed in such a way that the it can be expanded over for the coverage to other area’s but limited by design and functionality beyond the area outside Phase-I scope. The system will be the necessary slots (Blank Slots only, no spare hardware or software) available for the expansion, as an when during the course of other Phases the slots could be added with additional cards for increasing the capacity of the user’s required. But the system will have it’s own limitation in terms of additional slots, and the system may need a complete upgrade for accommodating all the user’s in terms of different Phases. All the upgrades with respect to Hardware & Software/Programming will have to be carried out by the contarctor responsible for Tetra Radio Communication under their Phase.
Telephone System.
The telephone system designed under Phase-I has the capability to be upgraded and the subscriber’s which will be commissioned under the other Phases of the project can be integrated into the main system installed and commissioned under Phase-I. The PABX main equipment installed under Phase-I will have spare slots (Blank Slots only, no spare hardware or software) to be plugged in with the required cards for the stations that will be commissioned under different Phases of the project. The main telephone system will be upgraded with hardware and software licenses to integrate the other Phases by the contractor responsible for Communication System for their Phase.
PAGA System.
The PAGA Central Cabinet will be located at the CCR, with the capability to interconnect with the remote PAGA Cabinets for the Phase-I locations. The Central Cabinet will have the capability to interconnect to the Remote PAGA Cabinets for the locations defined in other Phases, but will be limited to the design for Phase-I contract. For interconnection of the locations under other Phases stations including the BVS, Manifold and Wellheads the contractor responsible for communication

Rev: 00A Date: 21/02/12 Page: 36 of 36
network will upgrade the central PAGA System and also provide the relevant hardware.
Process CCTV System.
The Process CCTV Central Cabinet will be located at the CCR, with the capability to interconnect with the remote CCTV Cabinets for the Phase-I locations. The Central Cabinet will have the capability to interconnect to the Remote CCTV Cabinets for the locations defined in other Phases, but will be limited to the design for Phase-I contract. For interconnection of the locations under other Phases stations including the BVS, Manifold and Wellheads the contractor responsible for communication network will upgrade the central CCTV System and also provide the relevant hardware.
Power Supply.
The UPS power supply requirement is considered at full load for each equipment at the TER at CCB and other defined location supplied under Phase-I scope and any additional new equipment that will be provided under different Phases apart from Phase-I will have to be powered up by additional supplies or by upgrading the existing UPS supplies by the contractor responsible for communication network for that Phase.
