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

PCM-E16 is point-to-point E1 multiplexing device developed based on special large scale integrated circuits.PCM-E16 PCM multiplexing 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.

01.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;
