30 voice FXO/FXS E&M RS232 ethernet E1 over fiber PCM multiplexer:PCM-F30



PCM-F30 is the point-to-point optical transport equipment that uses the FPGA chips. It is single board structure and provided with complete alarming function. It provides 1~4 10/100M Ethernet channels, 1~30 voice (FXS/FXO) channels and 1~4 serial data channels,4E1 for option. It can realize SNMP management on stand-alone device via built-in SNMP module. The outer design use the standard 19 inches rack, so the volume is small, weight is light and operation is convenient and credit.



 01.Base on IC of independence intellectual property rights.
02.Adopt veneer structure.
03.Offer 1~4 ×2Mb/s digital interfaces.
04.Provide 1~4 channels of 10M/100M, support VLAN setting.
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.Provide 1~30 voice channels, supporting FXS/FXO.
07.When fiber signal is loss, users can distinguish whether the remote device is power off or the fiber line is down from the

indicator status on the local device.

08.1U/19inch type model can provide SNMP network management port independently. It can also support cascade

management. (optional).
09.User can become conscious of the temperature and voltage of the local device in SNMP managing interface. (Optional).
10.User can also become conscious of the temperature and voltage of the remote device in SNMP managing interface, and

can set the alarm threshold of the remote device’s temperature. (Optional).
11.180-260VAC & -48VDC power options and the positive and negative of DC-48V can be optional because there is the self

-test circuit for the polarity inside th1e device.
12.Standard 19 inches rack, little volume, light weight, steady capacity and convenient setup.
