2  Introduction 

The GE MDS TD 220 is a 25-Watt 220 MHz GMSK data radio intended for bridging ITCS messages 
over the air between locomotives and wayside devices.  The data interface is Ethernet, with UDP-
encapsulated ITCS message payload. 
 

 

 
Each second is divided into 8 133-byte time slots.  The first of the 8 timeslots each second is always 
reserved for bases A, B, or C to transmit beacon information to the mobiles in the area.  Following 
the beacon are 4 (or 5) time slots that are always reserved for mobiles to transmit.  At the end of 
each second, are 3 (or 2) time slots that can be used by bases or mobiles.  These slots are used with 
the following priority:  the previous base, the current base, and then mobiles.  In other words, during 
second 1 in the table below, base A actually has priority over the last three slots.  If A does not use 
them, B can use them.  If B does not use them, mobiles can.  Bases reserve these time slots with 
flags in the beacon.  This scheme maximizes the potential for utilizing all slots.

following the conventions outlined in the following figures.
