Ringer Cards

about us slider image

ICS is a reliable name in the domain of manufacturing Ringer Cards. The Ringer Card is a Micro Controller based unit that provides dial tone, busy tone, ring and ring back tones. In many of the Telephone exchanges, the ringer unit is inbuilt and a separate ringer is not available to cater the needs for the Leased/dialing circuits. In order to meet such requirements, ICS provides Ringer Cards installed in the exchanges.
