42 CHAPTER 2: INSTALLATIONConnecting to the T1/E1 UNI InterfaceAs shown above in Figure 18, the PathBuilder S330 T1/E1 UNI with IMA interfaceprovides four T1/E1 ports. You can connect a single T1/E1 line to this interface, orconnect up to four T1/E1 lines and combine them to form a logical,inverse-multiplexed high-speed link. See “Configuring UNI and IMA Groups” inChapter 4 for details about setting up IMA groups.If you are using a G703 coax physical connection to connect the E1 line to theinterface, you must use the E1 Balun Adapter (part number 3C63904).T1/E1 UNI Interface LEDs In addition to the common LEDs described earlier inthis chapter, the following LEDs indicate the status of each T1/E1 port. (SeeFigure 19.)The PathBuilder S330 has four of each of the following LEDs (one for each T1/E1port). The PathBuilder S310 has one of each of the following LEDs (for its oneT1/E1 port).ALARM PORT #N (red)—Powers up in the “off” state and illuminates when analarm condition is detected on the corresponding T1/E1 line.ONLINE PORT #N (green)—Powers up in the “off” state and illuminates whenyou set the administrative status of the T1/E1 port to In Service. See “Configuringthe T1/E1 Interface” in Chapter 4, for details about how to set the administrativestatus of the T1/E1 ports and/or IMA groups.Figure 19 PathBuilder S330 T1/E1 UNI LEDsConnecting to the Serial PortTo connect to the serial port, connect a DTE or DCE cable to the MOLEX 60-pinconnector on the front of the unit. The cable options for the serial port are:n DCE V.35—The connector type on the V.35 cable converter is 35-pinWinchester; female.n DTE/DCE RS-449—The connector type at the end of the RS-449 cable is DB-37subminiature; female for DCE, male for DTE.n DTE/DCE EIA530—The connector type at the end of the EIA530 cable is DB-25subminiature; female for DCE, male for DTE.n DTE/DCE X.21—The connector type at the end of the X.21 cable is DB-15subminiature; female for DCE, male for DTE.1 2 3 4AlarmOnlineNOTE: The PathBuilder S310has only one set of functioning LEDs
