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.
1.2 Physical Description
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)
