Installation and Operation Manual Chapter 1 Introduction

ASM-40CD Ver. 1.0 Physical Description 1-3

Remote Power Feeding

The phantom current option for ASM-40CD provides a connection from an

internal current supply to external G.703 repeaters (RPT-I, RPT-O) through the

line. A standalone power supply, LRS-PS-FEED, serves as a power feeding source

for this internal current supply, and must be ordered separately.

The LRS-PS-FEED is connected to the LRS-24 hub AC power supply interface

module, LRSI-F-PSP/230/115. This interface module connects the feeding voltage

to all the modules installed in the LRS-24. The phantom current is 50 mA.

Figure 1-3. ASM-40CD Card

The ASM-40CD front panel consists of LEDs, two fastening screws, and two

handles for removing the card from the hub.

ASM-40CD front panel LEDs indicate module and system status with respect to

transmitted data, signaling and serviceability (see

Figure 1-3

ASM-40CD couples to the LRS-24 hub backplane by three connectors, and

couples to the digital interface card by four card connectors (see

Figure 1-4)
