While -activities

You will hear two people, Dave Wells, the telecom manager of an Oil company in London and Jerry Rigg, a geophysicist in charge of a small exploration team in West Africa having a telephone conversation. Read the list of events. Then listen and number the order in which the events happen.

All the local loops are copper twister pair and the laid times are really long.

They may be able to get MPLS or Global Ethernet services in the future.

They’ve been travelling around trying to figure out what telecoms infrastructure is available.

What Jerry and Mgumba have found is that West Africa is connected to Europe via the South Atlantic and West Africa Submarine Cable which has a capacity of 120 gigabytes.

The PTT is rolling out a national fibre backbone to serve the existing local telephone exchanges.

The problem with the copper pairs in the ground is that they get dug up and stolen so they will need to ask that their services are provided using telegraph poles and terminated straight into the second floor office window.

Listen again to Dave and Jerry and tick the infrastructure that has been completed and is available, and cross out the one that is still being developed or planned.
