IDM-30A Multiservice PCM Multiplexer
IDM-30A Multiservice PCM Multiplexer
|
Overview |
IDM-30A PCM multiplexer transmits at most 30 channels of voice/telephone or data signals over coaxial cable or twisted pairs. IDM-30A is modular equipment. It could accommodate more than 10 types of plug-in cards including FXO/FXS, 2/4-wire E&M, V.24, V.35, Magnet, Hotline etc. All plug-in replaceable cards could be inserted into or removed from the slots on the main board, which makes IDM-30A very flexible.
