2.4.3  Channel Service Unit (CSU) (must be installed) 
The Channel Service Unit (CSU) provides the T1 connection between the iSC-3 and the 
telephone company that provides the T1 line. The CSU provides surge protection to the 
T1 line and loop-back testing for the telephone company. 
For more information about the CSU, refer to the manufacturer's documentation. 
2.4.4  GPS Antenna System (must be installed) 
The Global Positioning System (GPS) antenna provides GPS signals to the iSC-3, which 
constructs the timing reference for the MC-Series system hardware. One GPS antenna 
with a dedicated 50 Ω coax cable is required for each iSC-3.  
2.4.5  Powerplant (must be installed) 
The MC-Series system cabinet is powered by a nominal –48 VDC powerplant supplied by 
the customer. The powerplant may be installed in the cabinet or used externally. The 
cabinet is shipped with a Power Distribution Unit (PDU) installed in the cabinet. The PDU 
contains circuit breakers that provide overcurrent protection for MC-Series loads.
