NetVanta 6240/6250 Series HIG Physical Description61700202G1-34B Copyright © 2013 ADTRAN, Inc. 19Rear Panel DesignThe NetVanta 6250 Series rear panel is shown below.Figure 4. NetVanta 6250 Rear Panel LayoutRear Panel InterfacesVOICE ConnectionA single 50-pin female amphenol connector, labeled VOICE, provides the interconnect wiring for theanalog FXS/FXO circuits. See Table A-2 on page 34 for voice connector pinouts. The status LED,labeled VOICE, is located on the front panel.FXO InterfaceThe FXO 0/0 interface is an RJ-11 connector and provides analog trunks for local call routing. SeeTable A-3 on page 35 for the FXO interface pinouts.Network InterfacesThe T1 0/1 through T1 0/4 interfaces are DS1 RJ-48C pin connections. See Table A-4 on page 35 forthe network interface pinouts. The status LEDs, labeled T1 1 through 4, are located on the front panel.10/100Base-T Ethernet InterfacesThe ETH 0/1 through ETH 0/4 ports are RJ-45 connectors. See Table A-5 on page 35 for the Ethernetinterface pinouts. The status LEDs, labeled ETH 1 through 4, are located on the front panel.10/100/1000Base-T Ethernet InterfacesThe GIG 0/1 ports consist of one RJ-45 and one small form-factor pluggable (SFP) slot forconnectivity over fiber. (Use either the RJ-45 connector or the SFP slot. The fiber slot has precedence.)See Table A-6 on page 35 for the Ethernet interface pinouts. The status LED, labeled GIG 1, is locatedon the front panel.USB Interface (Future Release)The USB interface is Type A USB host connector and is provided for use with 3G/4G modems or flashdrives. The status LED, labeled USB, is located on the front panel. A USB power switch is used tolimit the current drawn by a device connected to the USB port.CRAFT InterfaceThe CRAFT interface is an EIA-232 serial port (DCE), which provides for local management andconfiguration (via a DB-9 female connector). See Table A-7 on page 36 for the craft interfacepinouts.The number of circuits used (1 through 24) is dependent on the model NetVanta 6250.FXO interfaces use circuits 17 through 24 depending on the model.Connection directly to an external modem requires a cross-over cable.CRAFTBBUGIG 0/110/100/1000BASE-TT1 0/1FXO0/0VOICET1 0/3ETH 0/4ETH 0/2AC INPUTDC INRTN -48VETH 0/1 ETH 0/3T1 0/2 T1 0/4USB
