IDM-30A 30 FXO over e1 converter transmits at most 30 channels of voice/telephone or data signals over coaxial cable or twisted pairs. IDM-30A is a modular equipment. It could accommodate more than ten types of plug-in cards including FXO, FXS, 4-wire E&M, 2-wire E&M, V.24, etc. All plug-in replaceable cards could be inserted into or removed from the slots on the main board at will, which makes IDM-30A very flexible.
Features
