BTTB to improve international service continuity with fibre deal

25 Feb 2008

Bangladesh Telegraph and Telephone Board (BTTB) has signed a deal worth around USD2.7 million with Power Grid Company of Bangladesh (PGCB) to install a back-up fibre-optic link between Dhaka and the SEA-ME-WE-4 submarine cable landing station at Cox’s Bazar, to ensure uninterrupted international voice and internet services, reports local newspaper the Daily Star. Since joining the undersea cable system in May 2006, BTTB has been operating with a single terrestrial optical connection between Cox’s Bazar and the capital – installed only a few feet below ground – which has been broken on numerous occasions, disrupting services. BTTB has reported eight incidents of ‘sabotage’ to the network as well as seven cases of ‘accidental disruption’, and has had to shut down the line an additional eight times for maintenance work. The state-run telco is reportedly using approximately 2.8Gbps voice and 1.24Gbps data bandwidth on the SEA-ME-WE-4 cable, whilst its total capacity allocation on the consortium-owned international network is more than 14Gbps.
