RAMO: management network for telecommunications environment equipment

The RAMO network is the fundamental tool for operating the technical environment equipment of telecommunications centres which concern the power supply, cooling system, building surveillance, access control, security, EMC and electrostatic environment. It implements functions which make it possible to analyse the quality of the equipment's performance in operation, to precisely identify equipment failures to reduce their mean time to repair. The type of equipment included in this network varies depending on the size of the centre which houses it. It comprises the power supply systems, consisting of an electrical generator, an AC distribution cabinet, a conversion and power storage cabinet from the Alfatel range, catering for all power requirements from 2.5 kVA to 60 kVA, and from the Geode range for power greater than 100 kVA, together with the cooling systems and uninterruptible power supplies. The networking of all these items of equipment on an X.25 protocol using France Telecom's operating architecture comprises the RAMO network.<>
