PCM multiplexer Product Description

PCM-F30 is a kind of point-to-point fiber transmission PCM multiplexer that developed based on special large scale integrated circuits.

It is with perfect alarm function, and has an alternative of 30 channels phones and 1~4 98M linear Ethernet ports (optional), 1~4 serial data (optional).

It can realize SNMP management on stand-alone device via built-in SNMP module (optional). The electric parts are all digital with small volume, high reliability, convenient for maintenance.



  • Based on IC of independent intellectual property rights;
  • Adopt veneer structure;
  • Can control the remote alarm status;
  • Can control the remote alarm status;
  • E1 is conformed to G.703, adopts full digital clock recovery and smooth phase lock technology;
  • Offer 2 extended ports for 1~4 asynchronous data, such as RS232/ RS485/RS422/Manchester; (optioanl)
  • Ethernet is 10M/100M,full/half duplex adaptive, support VLAN;(optioanl)
  • ETH support Auto-MDIX;
  • 1-30 channels phone, support call indication;
  • Audio ports support FXO and FXS,FXO connected with switches,FXS with users’ phone;
  • Support SNMP management; (optioanl)
  • Can distinguish the opposite device is shut down or fiber not connected well when testing lost optical signal;
  • User can become conscious of the temperature and voltage of the local device in network management stage;
  • 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; (optioanl)
  • Power supply:AC220V、DC-48V/DC24V etc;
  • More than 2~120km no relay transmission distance;

Ndërfaqja Fiber

Offer one optical interface,FC、SC for option;

“TX” is for optical signal output

“RX” is for optical signal inp

Ethernet port

PCM-F30 PCM multiplexer offers 1-4 100M linear Ethernet,10/100M、full/half duplex adaptive,support VLAN,and can auto learn the MAC address from the LAN connected with it,

and transfer the destination address as the frame of another LAN. Transparent to TCP/IP,

and provide safe, seamless connection between different interfaces. Widely used to network and monitor in WAN and LAN.

4 Ethernet ports:

  • 1 2 3 4 — totally 4 10/100Base-T ports on the front panel,RJ45,support AUTO-MDIX;
  • 4 Ethernet ports can be exchangeable,or set VLAN
  • LNK: link/data indication,on denotes connection well,wink is of data flow;
  • SPD:10/100M,on is

 SNMP network management(optional)

 PCM-F30 support independent SNMP network management(SNMP on the front panel,10/100M、full/half duplex adaptive),and the manage host can manage any local device with SNMP connected with IP MAN, and support across gateway communication. Also can one device with SNMP module, the other 2~16 with SNMP cascading module realizes centralized management.

  • Standard SNMP network management protocol, fully support MIB library;
  • SNMP support V1、V2、V3,and protocol encryption;
  • The monitored device number is determined by IP resource;
  • Support IE browser to check the settings;
  • Support program upgrading by IE browser;
  • Support TELNET management;
  • Graphic management interface,consistent with real device indication;


  • Support cross gateway communication,network management host can manage serval branch devices;
  • Support the local commanding the remote;
  • Fully display the history and current alarms;
