The product has very low output residual voltage, and can ensure the fast response time. The interface mode has the choices of RJ11, RJ45, connection terminals and the like; the protective lines can be divided into the single line type, double line type or multi-line type; the product can be used separately, and is typically applied to a telephone, ADSL, DDN,ISDN, fax machine, modem and SPC exchange.
