Fiber-32Voice + 8E1 +4*FE( Physical Isolation) Multiplexe

Type:FCP-O32E8F4pR4/FCP-S32E8F4pR4 Message

Description:The equipment provides 32*Voice 1 ~ 4 E1 interface 4 physical isolation 100M Ethernet interface (100M per wire speed independent bandwidth) and four extended service interfaces. 4 expansion service interface can be used as RS232/RS485/RS

Product Description
  The equipment provides 32*Voice 1 ~ 4 E1 interface 4 physical isolation 100M Ethernet interface (100M per wire speed independent bandwidth) and four extended service interfaces. 4 expansion service interface can be used as RS232/RS485/RS422 asynchronous data/TTL signal/dry contact signal and other transmission channels the application is very flexible.
Functional Properties
◆ based on independent intellectual property rights of integrated circuits;
◆ E1 interface in line with ITU-T G.703 recommendations the use of all-digital clock recovery and smooth phase-locked technology;
◆ Voice port to support FXO/FXS/2-4 Wire E&M/2-4 wire Audio/Magnet phone interfaceFXO port plug into PBXFXS port is connected to the user's telephone;
◆ Voice FXO / FXS access support for caller ID / reverse polarity billing / fax function;
◆ Both sides of the device support FXO+FXS hybrid access;
◆ Provide 4 expansion interface you can extend 1 ~ 4 asynchronous data such as RS232/RS485/RS422/TTL etc .; or 1 to 8 dry contact;
◆ 4*FE Ethernet interface 10/100M full/half duplex fully adaptive each independent bandwidth wire speed 100M the total bandwidth can be two-direction 4*100M;
◆ Each Ethernet port supports Auto-MDIX (cross / direct wire adaptation);
◆ No relay transmission distance of up to 2 to 100 km; to provide the main optical fiber interface and backup fiber interface dual optical port backup function to ensure that business never interrupted;
◆ Supports Console network management and independent SNMP network management mode;
◆ A variety of power supply options: AC220V DC-48V / DC24V etc .; support AC + DC; AC + AC; DC + DC and other dual power backup mode;
◆ Telephone/Ethernet/Serial interface with lightning protection lightning protection to IEC61000-4-5 short-circuit current wave 10/700μs open peak output voltage 6KV standard;
