8 ports FXO/FXS over fiber PCM Multiplexer

1-8 ports FXO/FXS E&M and RS232 E1 Ethernet fiber PCM multiplexer:PCM-F08

Introduce
PCM-F08 is the point-to-point fiber PCM multiplexer optical transport equipment based on self copyright IC. It is single board structure and provided with complete alarming function. It offers 1~4 10/100M Ethernet channels and 1~8 voice (FXS/FXO) channels and 1~4 serial data channels 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.

PCM-F08 can offer 1-4 channels Ethernet 10/100M ,full/duplex auto-negotiation LAN interface, support VLAN protocol, this interface can continuously learn MAC addresses from the LAN that connected with it, and send the address as frame in another LAN. Transparent to TCP/IP protocol, offers security connection between different equipments in the network, used widely in network connection and monitor between WAN and LAN.

Features

• Base on self copyright IC.
• Adopt veneer structure.
• Can monitor the remote alarm status.
• E1 is conformed with G.703, and adopts full digital clock recovery and smooth phase lock technology.
• 1~8 channels voices, support call indication.
• Ethernet : 10M/100M, full/ half duplex adaptive, support VLAN setting and Auto-MDIX.
• Provide 2 extensional ports that can extend various data channels, such as 1~4 channels asynchronous data RS232/RS485/RS422/Manchester.
• The voice supports FXO and FXS ports, the FXO connected with the switcher, FXS with the phones.
• Support independent SNMP.
• Can monitor the local temperature and voltage.
• Serval power supply modes: AC220V, DC-48V.
• 2~120KM transmission distance without relay.
