Product Overview:
Confederate Communications 128roadMulti-serviceTelephone Optical Terminals are developed by the company.PCMPoint-to-point optical transmission equipment developed on the basis of VLSI for optical fiber transmission. Based on modular design, provide128Road telephone,4road10M/100MFast Ethernet Interface (Line Speed)100M) Or4road10/100/1000MGigabit Ethernet Interface (Line Speed)1000M），4The Ethernet interface is a switching port and can be supported.VLANPartitioning can be set to logical isolation. Just so so2Path Extension Business Interfaces such asRS232/RS485/RS422Asynchronous data, switching signal, Ethernet signal (bandwidth)2M) Equal transmission channel, application is very flexible. It has perfect alarm function, stable and reliable operation, low power consumption, high integration and small size.

Functional features:
Ø The telephone optical terminal is based on the integrated circuit of independent intellectual property rights.
Ø Plug-in card design facilitates the replacement of problematic voice paths and avoids integral equipment.1The whole machine needs to be replaced when there is a problem with the road telephone.
Ø It is convenient to expand the capacity, increase the card, maintain and replace the card.

Ø Maximum configuration of this device256Road, if the user wants to60On the basis of road expansion, only the telephone board card can be added.
Ø 128Road voice, supporting caller display function and anti-polarity billing function;
Ø Supporting the mutual playback function of each site;
Ø Voice Port SupportFXOMouth andFXSMouth,FXOThe port is connected with the SPC switch.FXSThe port is connected to the user's telephone.
Ø Optional4Network Ethernet interface is switching port, it can also be partitioned.VLAN；
Ø Ethernet Interface Rate is 100 Mbp or Gigabit Optional, Full Duplex/Semi-duplex adaptive;
Ø It has the function of viewing and displaying the working state of remote equipment at the end.
Ø Reachable transmission distance without relay2~120Km;
Ø A variety of power supply options:AC220V、DC-48V/DC24VEtc.
Ø DC-48V/DC24VThe power supply has the function of automatic polarity detection, and there is no need to distinguish the positive and negative poles when it is installed.
Ø Telephone interface with lightning protection, radar protectionGB/T17626.5(IEC61000-4-5) Short circuit current wave8/20μsOpen-circuit peak output voltage6KVStandards.
