SHM 128 - 511004311 - Update: 11/25/2004                                                       22/31 

VI - RANGE 

 
The distances indicated below correspond to a guaranteed minimum 
range for twisted pairs of 

∅

 4mm (AWG26). 

For other diameters multiply roughly by: 

1.3 for 

∅

 0.5 mm (AWG24) ; 1.5 for 

∅

 0.6 mm (AWG22); 

2.0 for 

∅

 0.8 mm (AWG20) 

 
The range depends on the transmit clock used by modems: 
 
1) TC = internal clock for both modems (RS232, V35). 
   TC = receive clock for both modems (RS232, V35, R422).
