Description:
The IT Infrastructure Service maintains the communications network of the Miguel Hernández University across its 5 locations: Elche, Altea, Orihuela Desamparados, Orihuela Salesas, and San Juan, which correspond to the 4 campuses into which it is divided.

This network allows us to manage all services requiring information transmission: data, images, voice, etc., and for this purpose, the necessary network services are maintained: DHCP, DNS, WINS, etc.

The network is managed in a coherent and unified manner, allowing for its technological evolution and that of the services offered without requiring substantial changes in its conception. Likewise, the installed infrastructure must reach all workplaces so that it can be used in the daily work of all users.

The general structure consists of five nodes located in each of the current 4 campuses (Elche, Sant Joan, Orihuela Desamparados, and Altea) and in the Orihuela Salesas headquarters. Connecting these nodes, there are a series of inter-campus data communication links based on DWDM technology over dark fiber formed by three nodes: one located in Elche, another in Sant Joan, and another in Orihuela Desamparados. The topology is star-shaped, with the center located in Elche and the ends being the Sant Joan and Orihuela Desamparados nodes.

Between the Elche – Sant Joan nodes, there are currently 10G services, 4G Fibre Channel, and 4-channel E1 multiplexing. Between the Elche – Orihuela nodes, 1G services are available. For this, a double DUSAC cabinet has been set up in each node in a TWIN configuration (1+1 protection); each DUSAC cabinet has an FTX-6G transponder for transporting E1 channel services and another FTX-7G transponder for transporting 4G Fibre Channel.

For the transport of E1 channels between Elche and Sant Joan and between Elche and Orihuela, a MUX-703 card has been simultaneously arranged, insertable into a DUSAC cabinet, which is responsible for multiplexing and converting the electrical signals of the E1 and converting them into optical signals to be delivered to the two FTX-6G transponders.

The Altea campus and the Salesas headquarters have a Metrolan access with a 20 Mbps bandwidth. Metrolan accesses at all sites are delivered via FastEthernet or Ethernet interfaces depending on the access bandwidth; currently, these accesses are connected to the network core electronics of the Elche and San Juan Campus.

The existing Macrolan connection at the Elche campus, in addition to providing IP connectivity to the Altea campus and Salesas headquarters, serves as a central communication point for 3 training classrooms with videoconferencing systems located in the Elche, Alicante, and Elda Hospitals.

Within each of the four campuses, the necessary conduits have been carried out to link all buildings using fiber optic and telephone multipair cables.
