- DVOP-HM-E104-EG4-T16-DB4 Multiservice telephone optical terminal
This series of products is a point-to-point optical transmission device developed on the basis of the special VLSI developed by the company. This product provides 16 telephone interfaces; Four E1 ports; Four Gigabit Ethernet interfaces; Two expansion ports (can expand 1 to 4 asynchronous data, such as RS232/ RS485/RS422/Manchester code, etc.); 1 Console and 2 optical ports (1+1 optical backup); The internal circuit part of the equipment adopts all-digital circuit, the whole machine works reliably, stability, low power consumption, high integration, small size, easy to install and maintain.
● Integrated circuits based on independent intellectual property rights
● The whole machine is single-board design
● E1 interface complies with G.703 recommendation, using full digital clock recovery and smooth phase-lock technology
● Two extension interfaces (AUX1/2), can extend 1 ~ 4 asynchronous data, such as RS232/ RS485/RS422/Manchester code; Or 1 to 8 switches, 1 to 4 E1 channels (therefore, the device can have up to 8 E1 channels), 1 to 4 voice channels, or two/four wire audio
● Ethernet interface 10/100/1000M, full/half duplex fully adaptive
● Each Ethernet port supports Auto-MDIX(cross/straight line adaptive)
● 16 channels voice access, support caller ID function and reverse polarity billing function
● One Console port, supporting Hyperterminal control devices
● Support each site mutual number allocation function
● Voice ports support FXO ports and FXS ports. FXO ports are connected to program-controlled switches, and FXS ports are connected to users' telephone sets
● Can monitor local temperature and local voltage (network management platform)
● Optical port no relay transmission distance up to 2 ~ 120 km
● Multiple power supply options: AC220V, DC-48V/DC24V, etc
● DC-48V/DC24V power supply with polarity automatic detection function, no need to distinguish between positive and negative terminals during installation
