16 Phone over E1 multiplexer,FXO/FXS E&M ETH PCM multiplexer:PCM-E16

IntroducePCM-E16 is point-to-point E1 multiplexing device developed based on special large scale integrated circuits. It has an alternative of 16 digital office phones and 1~4 serial data ports with perfect alarm functions, realizing SNMP management. The electric parts are all digital, high integration, low volume, convenient for maintenance.  The device offers 16 channels voice+1 ETH, other functions are reserve.

Features01.Based on the independent intellectual property rights of the integrated circuit; 02.Whole veneer design;03.Can monitor the opposite alarm status;04.E1 is conformed with G.703，adopts fully digital clock recovery and smooth phase lock technology; 05.Provide 2 extensional ports that can extend various data channels, such as asynchronous data (RS232/RS485/RS422/Manchester), switching value, E1, voice or 2/4-wire audio.06.1~16 voices access and support call indication;07.Audio ports support FXO and FXS，FXO connected with switches，FXS with users' phone；08.Support SNMP management, and network management cascading (optional); 09.Can control local temperature and voltage; 10.Can monitor the opposite temperature and voltage，and set the threshold; 11.Power supply:AC220V、DC-48V;12.More than 2~120km no relay transmission distance;
