System for supporting in-field testing of links of a communication network

A system for supporting in-field testing of a plurality of parallel links of a communication network, said plurality of parallel links being alternatively connectable to a further link of said communication network, said system comprising:

• a first portable device comprising an input port and a number of output ports, wherein said input port is manually connectable to said further link and each one of said output ports is manually connectable to a respective one of said plurality of parallel links, to be tested, said first portable device further comprising a number of switches and a data processing unit, said data processing unit being capable of switching each one of said number of switches between a closed status, where it provides signal continuity between a respective one of said output ports and said input port, and an open status where it isolates said respective one of said output ports from said input port;
• and
• a second portable device capable of transmitting a command to said first portable device via a bidirectional radio channel, said command being capable of inducing said data processing unit to bring one of said number of switches in said closed status.
