Leading telecommunication and networking companies employ our
communication line protectors in their installations for good reason;
because they provide greater assurance of network, Voice over Internet
Protocol (VoIP) and PBX uptime with a lower service cost than
conventional protectors. Events such as system lockups, transmission
errors, "no trouble-found" service calls, shortened component life - all
are problems that can result from surge voltages on networking and
communications equipment.
