1.Scope of Supply of Plant and Services
1.1Brief Description of the Scope
In order to fulfill the objectives SASEC information Highway Project a SASEC Regional Network involving four SAARC countries namely Bangladesh, India, Nepal and Bhutan has to be built. The Scope of the present procurement is to construct the Bangladesh component of the SASEC Regional Network by procuring necessary Goods, Equipment, Materials, Services and Works. The details of the Bangladesh component of the SASEC Regional Network is given below:
The Bangladesh component of the SASEC Regional Network mainly consists of a core IP Router, four numbers of new multi service optical transmission nodes and a part of the existing transmission network of BTCL. The core router will be installed at Moghbazar, Dhaka and will function as Gateway router for connecting other IP networks of Bangladesh and the other gateway routers of SASEC Regional Network to be installed at different places of India, Nepal and Bhutan. The core routers will be MPLS enabled and will have both PoS (STM-1/STM-4) and Ethernet (GE and FE) interfaces. Besides the core router, there will be an aggregation switch at Moghbazar. Also, there will be a NMS, a Bandwidth Management Gateway and Operation Support System (OSS) at Moghbazar for ease of operation and maintenance.
Core Router at Moghbazar will have the provision to connect the SASEC Community E-Centers (CeCs) and SASEC Research & Training Network (RTN) in future. These SASEC CeCs and SASEC RTN will be established as a part of SASEC project.
For transportation of IP traffic between Panchagarh and Dhaka and between Panchagarh and Shiliguri, two numbers of Multi Service optical transmission equipment (MSPP) will be required, one for Panchagarh and the other for Thakurgaon. To provision an alternate path for the IP traffic between Dhaka router and the Shiliguri Router of the SASEC Regional network two additional MSPP will be required, one of which will be installed at Chuadanga and the other at Meherpur. The initial capacity of these transmission equipment will be STM-16 but can be easily upgraded to STM-64 capacity. From Dhaka to Dinajpur and Dhaka to Kushtia, BTCL has optical transmission system of STM-16 or higher capacity. The existing optical transmission link of BTCL in Dinajpur-Thakurgaon-Panchagarh and Kushtia-Meherpur-Chuadanga routes are of STM-1 capacity. BTCL have enough fibers in the above mentioned route. Hence, the STM-16 optical transmission equipment proposed for Thakurgaon, Panchagarh, Chuadanga and Meherpur will operate over the fibers of BTCL. For connecting the optical transmission equipment of Panchagarh to Shiliguri, India, around 56 km OF cable will be laid from Panchagarh BTCL station to Indian border at Banglabandha. There is optic fiber cable connectivity between Chuadanga and Kolkata which is operated by BTCL in Bangladesh and BSNL in India. There will be STM-1/STM-4 PoS and GE interfaces in the Router to be installed at Dhaka to connect the routers at India, Nepal and Bhutan. The transmission equipment at Thakurgaon will provide STM-16 connectivity for the Panchagarh transmission equipment and to the BTCL’s existing optical transmission equipment at Dinajpur. Similarly, the transmission equipment at Meherpur will provide STM-16 connectivity for the Chuadanga transmission equipment and to the BTCL’s existing optical transmission equipment at Kushtia.
