2.2 Back-up communications systems

CARE staff in the field must always have access to at least two communications systems at all times in case one system fails. The Telecommunications and IT Support Manager must ensure that back-up telecoms systems are in place for all staff. Back-up systems allow remote offices and staff to communicate if the primary system fails. An effective back-up system usually involves a mix of landline or cell phones as primary systems, and radio or satellite phone as secondary systems. Telephone systems are often not reliable during emergencies, and the primary system may start out being a satellite phone (for example, Thuraya) with the back-up system being a different satellite phone system (for example, Iridium) or transceiver radios (VHF or HF).
