27 284.3 POWER CONNECTIONThe Model 2715 offers three ways to supply external power: ACpower, DC power and interface power.4.3.1 Using the AC Power Supply (100-240VAC)The Model 2715 uses a 5VDC, 2A universal input 100-240VAC,power supply (center pin is +5V). The universal input power supply isequipped with a male IEC-320 power entry connector. This power sup-ply connects to the Model 2715 by means of a barrel jack on the rearpanel. There are a variety of international power cords available forthe universal power supply. The Model 2715 powers up as soon as itis plugged into an AC outlet–there is no power switch.4.3.2 Supplying DC PowerThe 36-60 VDC DC to DC adapter is supplied with the DC versionof the Model 2715. The black and red leads plug into a DC source(nominal 48VDC) and the barrel power connector plugs into the barrelpower supply jack on the 2715.4.3.3 Supplying Power via pin KKYou may also supply DC power directly to pin KK of the V.35 inter-face. DC Power supplied to pin KK must be +5VDC ± 5%, 300mAminimum.NOTE: Model 2715 is factory configured to accept power from theenclosed DC wall adapter (See Sections 4.3.1 and 4.3.2 above).If you wish to supply power via pin KK on the interface, you mustchange the setting of thepower supply jumper on the printed cir-cuit board See Appendix E. All power sources must be SELV(Circuit, Safety Extra Low Voltage) specified. (See CENELECEN60950, Section 1.2.8.5)5.0 OPERATIONOnce the Model 2715 is installed and configured properly it is readyto place into operation. This section describes the function of the LEDindicators, and the use of the loopback and pattern test modes.5.1 LED DESCRIPTIONSThe Model 2715 is equipped with seven LED indicators that moni-tor the status of communication. Figure 4 (below) shows the locationof the LEDs on the Model 2715 front panel.TXD When the unit sends a one, the TXD LED isturned on. When it sends a zero, the TXDLED is turned off. Moreover, the TXD LEDis active only in active DS0 channels. Ininactive channels, the TXD LED is off.RXD When the unit receives a one, the RXD LEDis turned on. When it receives a zero, theRXD LED is turned off. Moreover, the RXDLED is active only in active DS0 channels.In inactive channels, the RXD LED is off.RXDLOSALMERRT/LPWRTXDModel 2702G.703 Interface ConverterFigure 4.
