5.3.2  Connecting FXS Interfaces Directly to MDF 
If you are using your own third-party MDF, follow the instructions below for connecting the 
FXS analog equipment to the device directly through the MDF. 
 
 
Warning:  To reduce noise interference, use a twisted pair Octopus cable that is 
terminated on a metal-hooded 50-pin Telco connector. 
 
ļ  To connect FXS interfaces directly to the MDF: 
1.  Wire the 50-pin Telco connectors according to the pinouts in Table  5-1. 
2.  Connect the wire-pairs at the other end of the cable to a male 50-pin Telco connector 
(not supplied). 
3.  Insert and fasten the male connector to the female 50-pin Telco connector on the 
device's rear panel (labeled ANALOG FXS LINES 1-24).
